.KEY MESSAGES... Updated at 1238 AM CDT Sat Sep 12 2026
- An elevated risk for localized heavy rainfall leading to street flooding and overflowing of poor drainage will continue today.
- Lower rain chances and warmer temps return next week.
&&
.SHORT TERM... (Now through Tuesday) Issued at 1238 AM CDT Sat Sep 12 2026
A shortwave trough axis moving trough the region will continue to bring increased rain chances to the area today. This trough will interact with a very moist environment as noted by PWATS of 2 to 2.2 inches which are in excess of the 75th percentile for this time of year. As temperatures warm into the 80s, updraft development will begin in the mid- morning hours and scattered to numerous showers and storms will start to fire up by the late morning hours. These showers and storms will continue to fire up through the mid to late afternoon hours before beginning dissipate in the evening hours with the loss of daytime heating. Storm motion will remain around 10 mph and rainfall rates of 2 to 3 inches per hour can be expected with the strongest storms. As a result, another day of localized flooding concerns, especially for low lying and poorly drained urban areas, will be in play. The region remains in a level 1 out of 5, marginal, risk of flooding for today.
The trough axis will begin to pull east of the area tomorrow and a broad upper level ridge over Texas will start to expand eastward. As the influence of the ridge increases, the mid and upper levels of the atmosphere will begin to both warm and dry in response to increasing subsidence on Sunday and Monday. This will allow PWATS to fall to between 1.8 and 2 inches. These values are still elevated for this of year at between the median and 75th percentile, but the increasing ridging aloft will help to somewhat limit updraft development. Convective activity will struggle to maintain itself until temperatures warm into the lower 90s and the weak mid- level capping inversion is overcome. Overall, shower and storm coverage will be lower and will be more confined to the sea breeze and lake breeze boundaries where low level forcing is maximized. PoP will be closer to average in the 30 to 50 percent range. Another concern will the threat of stronger wind gusts with the most intense storms that form. Drier air will easily entrain in the tallest updrafts and this could lead to winds of 40 to 50 mph with these more intense storms. An isolated severe wind gust of 60 mph cannot be ruled out for Sunday and Monday. This is supported by DCAPE values of around 1100 J/KG and favorable model sounding profiles exhibiting very steep lapse rates below 3km in excess of 8.0C/km.
By Tuesday, continued drying and warming aloft as the ridge becomes centered over the Tennessee Valley will push PWATS down to around the median values for this time of year. Convection will fire up later in the day, more toward the mid to late afternoon, when the convective temperatures in the low to mid 90s are reached. The end result will be more isolated to widely scattered showers and storms and PoP of 20 to 40 percent. Once again, storms will fire up first along the sea breeze and lake breeze boundaries and then fire up along outflow from the previous convection as those first storms collapse shortly after forming. Although the severe threat will be lower on Tuesday, one or two storms could turn strong enough to pull in some drier air aloft and produce damaging wind gusts.
&&
.LONG TERM... (Tuesday night through Friday) Issued at 1238 AM CDT Sat Sep 12 2026
By Tuesday night, upper level ridging is expected to be centered (598dm) near Chattanooga, Tennessee. Meanwhile, an upper trough that moves off the Mid-Atlantic coast Monday night and Tuesday is expected to close off a low off the coast of the Carolinas Wednesday and head southwestward around the upper ridge, crossing Florida and entering the eastern Gulf Thursday night into Friday. There's actually pretty decent agreement on the mid level feature between the GFS and ECMWF operational runs from the daytime hours Friday, at least through the end of the workweek next week.
At this time, neither of the medium range models develops a surface low over the Gulf with this mid level feature. The drying of the airmass that is anticipated from the ridging on Sunday and Monday actually continues through most of the workweek, with precipitable water values even on Friday forecast to remain between the 50th and 75th percentiles in most of the area (1.5 to 1.8 inches).
If the moisture depicted in the forecast soundings is in the ballpark, we may not see a lot of thunderstorms during the workweek. That would also mean the hot weather continues for most of next week with temperatures in the mid 90s looking reasonable. May not be enough humidity to justify heat advisories though.
Beyond next Friday, the global operational models fall out of agreement with each other. The ECMWF continues to take the mid level system westward to the Texas coast without a lot of impact. The 18z GFS brings it to about 90W before starting to drift it east next weekend. We'll worry about those differences when next weekend falls within the range of the forecast.
&&
.AVIATION... (06Z TAFS) Issued at 1238 AM CDT Sat Sep 12 2026
A weak inversion has formed over southwest Mississippi this morning in relation to light boundary layer winds and continued high relative humidity. This has resulted in LIFR low stratus and fog development at MCB in the last hour. These conditions will persist through around 13z before quickly mixing out as temperatures begin to warm and inversion lifts. Outside of MCB, prevailing VFR conditions are expected at the remaining terminals through daybreak. After 16-17z, scattered showers and storms will begin to develop and could impact any of the terminals. PROB30 wording is in place from 17z to 23z at the majority of the terminals for thunderstorm impacts with gusty winds of 20 to 25 knots, lightning, and brief reductions in visibility.
&&
.MARINE... Issued at 1238 AM CDT Sat Sep 12 2026
Winds will turn more south-southwesterly but with the Bermuda ridge centered well east of the area, wind speeds should be light at 10 knots or less today. The high will become more centered over the north-central Gulf Sunday into next week. This will cause winds to turn more south-southeasterly and even light/variable at times. Seas will generally remain in the 2 feet or less range. Additionally, thunderstorm activity will develop each day, peaking in the early to mid-morning hours, and these storms will produce higher wind gusts, waterspouts, and lightning concerns.

Area Forecast Discussion National Weather Service Cleveland OH 235 PM EDT Mon Sep 14 2026
.WHAT HAS CHANGED... The forecast largely remains on track and no significant changes were needed with this update.
&&
.KEY MESSAGES... 1) Cool temperatures and dry weather expected tonight.
2) An unsettled and humid weather pattern returns Tuesday through late week. A few strong storms are possible in Northwest Ohio Tuesday night, although confidence is low.
&&
.DISCUSSION... KEY MESSAGE 1... High pressure will remain in place over the region through tonight. Clear skies will allow for efficient radiational cooling and expect lows in the upper 40s and lower 50s. A few spots across interior NE PA may manage to drip into the low to mid 40s if cooling ends up being more efficient than currently anticipated. This will be the last chilly night of the workweek before temperatures warm up Tuesday onwards.
KEY MESSAGE 2... After a brief break in the unsettled weather pattern, multiple rounds of showers and thunderstorms will likely impact the area late Tuesday through at least Thursday. The first round of showers and thunderstorms will arrive behind a warm front and with a pre-frontal trough Tuesday evening. There is a small chance of a couple of stronger storms Tuesday evening into Tuesday night, although most CAMs suggest that the best instability will be to the west of the local area and storms will be coming in during a diurnally unfavorable time of day. The severe weather risk may be a little bit higher if storms end up moving in earlier than currently anticipated, but either way bulk shear values of around 30 knots supports an SPC Marginal Risk (Level 1 of 5) of severe weather with damaging wind gusts being the main concern.
From there, a cold front will push southeast across at least a portion of the area before slowing and wavering over the region Wednesday through late Thursday. This will result in periodic showers and thunderstorms for the mid to late week timeframe. There may be opportunities for a few stronger storms given the proximity of the front, but there is still uncertainty in the exact placement of the boundary and the amount of instability in place each afternoon. Will need to keep an eye on the forecast and update as needed.
It will also be quite humid and warm across the area with highs in the 80s and dew points in the upper 60s and low to mid 70s Wednesday and Thursday. PWAT values will increase to 1.5 to at least 2 inches during this time and flow parallel to the boundary may result in potential in heavy rainfall rates and training showers/thunderstorms.
&&
.AVIATION /18Z Monday THROUGH Saturday/... High pressure continues to provide for cooler, drier, and VFR conditions through the TAF period. FEW-SCT cumulus around 4000 feet across parts of NE OH/NW PA will continue to clear out through this evening. High clouds will filter through at times. Fog is generally not expected tonight due to a light breeze. Speaking of, north-northeast winds at under 10kt this afternoon will remain light while shifting south-southeast tonight. Winds increase to around 10kt out of the south-southwest on Tuesday.
Outlook...Non-VFR at times in scattered showers/storms Tuesday night through Thursday night.
&&
.MARINE... Light and variable winds will continue through early this evening before shifting to the southeast and increasing to 10 to 20 knots ahead of an approaching warm front tonight into Tuesday morning. There may a brief period where winds in the nearshore zones (especially in the western basin) touch 20 knots Tuesday morning, however confidence in winds of 20+ knots is highest in the open waters. Have opted against a Small Craft Advisory for the time being, but will need to keep an eye on wind speeds. The offshore winds will mitigate wave heights and keep the risk of rip currents relatively low. Offshore winds will diminish to roughly 10 to 15 knots Tuesday evening with flow becoming more southwesterly behind the warm front Tuesday night into early Wednesday. Northeast winds of 10 knots or less are expected on the lake as a frontal boundary wavers over the region Wednesday with flow becoming variable Thursday through the end of the week. Winds/waves should remain below Small Craft Advisory limits late this week.

AREA FORECAST DISCUSSION...UPDATED National Weather Service Jackson KY 1215 AM EDT Sun Sep 13 2026
.KEY MESSAGES...
- Areas of fog could become locally dense into the start of the morning.
- Temperatures will increase to well above normal, or even near record, levels by the middle of next week.
&&
.UPDATE... Issued at 1215 AM EDT SUN SEP 13 2026
A pesky stray thunderstorm to the northwest is not enough to justify keeping or extending the flood watch after a mostly dry evening. For that reason - and in concurrence with all the CAMs guidance - the Flood Watch was dropped before midnight. Otherwise, have updated the forecast for the latest obs and trends of the T/Td/Sky grids along with PoPs through dawn. Still expect areas of fog becoming locally thick with a potential for low stratus thick substantial enough for even some spits of sprinkles or drizzle into the morning. These adjustments have been sent to the NDFD and web servers along with a freshening of the HWO, zones, and SAFs.
&&
.SHORT TERM...(This evening through Sunday night) Issued at 452 PM EDT SAT SEP 12 2026
An area of light to moderate rain continues across portions of southeastern Kentucky late this afternoon, along with generally more discrete activity over the Bluegrass and west of Lake Cumberland. The clouds and precipitation have held temperatures on the cool side, ranging mainly in the 70s to lower 80s. Also, the heaviest rainfall totals have fallen outside of the Flood Watch area so far, with no reported impacts, but trends will need continued monitoring through the evening. Instability remains on the weak, skinny side, generally between 1000 and 1500 J/kg of MLCAPE, with anomalously moist PWATs near 2.0 inches, a deep warm- cloud layer, and weak Corfidi upstream vectors around 10 kts or less--all still favorable for torrential rainfall and backbuilding. The latest surface analysis shows a warm frontal boundary draped northeast of the area from North Carolina up into central West Virginia, across Ohio, to over southern Lake Michigan. Meanwhile, a cold front extends from Ontario southwestward over Chicago and St. Louis. Looking aloft, a 500 hPa shortwave trough axis extends from Cincinnati to Nashville to Huntsville. Additional weaker shortwave energy is located upstream along the cold front.
The primary focus through this evening will be continued rounds of convection and the potential for training and backbuilding leading to instances of isolated flash flooding ahead of the upper-level shortwave trough. As mentioned prior, most of the substantial rainfall has occurred outside of the Flood Watch, and guidance is not hitting the Flood Watch area particularly hard this evening. However, given the favorable environment and mediocre CAM performance, the Watch will remain in place for now. Otherwise, look for convection to diminish this evening as the 500 hPa trough axis passes overhead. Lingering low-level moisture will then favor plenty of fog and low stratus overnight. Additionally, a second 700 hPa vort lobe will pass late tonight and Sunday morning, when model soundings still show a little instability in the lowest few hundred hPa of the troposphere -- perhaps enough for a few light showers in addition to drizzle. Therefore, there is still a low chance of precipitation (10 to 30 percent) in the forecast closer to daybreak. Otherwise, low-level moisture will gradually thin during the day Sunday as weak 500 hPa shortwave ridging moves overhead. The aforementioned cold front then approaches Sunday evening from the northwest and sags southward across the CWA Sunday night. Upper-level support appears to be fading as the boundary approaches, but a few showers or thunderstorms cannot be ruled out, with the best chances toward and northwest of I-64.
In sensible weather terms, look for showers and thunderstorms to impact much of the area through this evening, though a few places could stay dry. Where activity is most persistent, there could be instances of flooding. Otherwise, it will be mild and muggy, with fog, variable cloud cover, and perhaps a few light showers or patchy drizzle late. Look for low temperatures ranging through the mid to upper 60s. Looking ahead to Sunday, morning low clouds and fog yield to increasing sunshine. It will be seasonably warm, with highs in the lower to middle 80s. Clouds increase Sunday evening and give way to a chance of showers and thunderstorms, with the best chances in the northwest. It will again be seasonably mild, with lows ranging through the 60s.
.LONG TERM...(Monday through Saturday) Issued at 302 PM EDT SAT SEP 12 2026
To open the extended period, prominent features at 500 mb include a trough over the Northeast, a ridge extending from the Upper Midwest down through the Mississippi Valley, while a second trough is modeled over the Northern Rockies. The upper pattern remains fairly progressive, with the ridge moving east over the Southeast US and Ohio Valley by Tuesday, lasting through Wednesday. Thursday through Saturday, the second trough modeled over the Northern Rockies by Monday will slowly break the upper ridge down, ushering in cooler weather for Friday and Saturday.
For sensible weather, the new work week starts with a surface cold front having just passed southeast of the area. Some lingering isolated showers remain possible early along the Virginia-Kentucky border. Some residual river valley fog should mix out by mid-morning. Temperatures will be cooler, ranging from the upper 70s to mid 80s from north to south. A mix of sun and clouds can be expected early, becoming fair in the afternoon and evening. With skies clearing out Monday night and high pressure building in, temperatures cool into the low to mid 50s in the valleys, with upper 50s to low 60s along ridge tops. River valley fog is expected to develop again Monday night before mixing out Tuesday morning.
With the ridge shifting into the Southeast, high pressure builds into the region, leading to temperatures warming into the upper 80s to low 90s through Thursday. Shortwave energy associated with the second trough brings shower and storm chances back to the CWA Thursday through Saturday. A cold front looks to progress into the forecast area from the Ohio Valley before stalling out Saturday. Agreement among model and ensemble guidance does widen heading towards the end of the week. With troughing energy seemingly breaking down the ridge heading into the weekend, high temperatures lax some, ranging from the mid 80s to upper 80s north to south on Friday, and low 80s to mid 80s north to south on Saturday.
&&
.AVIATION...(For the 00Z TAFS through 00Z Sunday evening) ISSUED AT 805 PM EDT SAT SEP 12 2026
Widely varying conditions were in place across eastern Kentucky at the 00z TAF issuance, ranging from IFR under low clouds to VFR under clear skies. A few showers will remain possible this evening with the passage of an upper level trough, but most locations should remain rain-free. Of more note, fog and/or low stratus are expected to develop overnight amidst weak upslope flow and the leftover moisture from today's rainfall. This will lead to poor flying conditions across much of the area through daybreak Sunday with IFR or worse conditions probable. Winds will remain light and variable overnight and then become westerly around 5 knots or less during the day on Sunday.

Area Forecast Discussion National Weather Service Boston/Norton MA 226 PM EDT Sun Sep 13 2026
.WHAT HAS CHANGED... The heaviest rainfall has come to an end, with remaining showers tapering off from west to east through early this evening. Additional significant rainfall is not expected, though localized nuisance flooding may linger given the 2 to 4 inches of rain that fell across portions of Rhode Island and southeast Massachusetts today. Lastly, Small Craft Advisories issued for most waters starting Monday afternoon through Monday night for gusty winds.

.KEY MESSAGES...
- Heaviest rainfall ending, drier overnight, though low clouds and areas of fog are possible. A stray early morning shower remains possible too.
- Dry and fall-like Monday into Tuesday, with a chilly start Tuesday morning.
- High pressure in control next week brings generally quiet weather. Brief bout of summer warmth and humidity expected Wed- Fri.

.DISCUSSION... KEY MESSAGE 1...Heaviest rainfall ending, drier overnight, though low clouds and areas of fog are possible. A stray early morning shower remains possible too.
The back edge of the heaviest rain is now working from west to east across southern New England, with clouds thinning across eastern New York and approaching western Massachusetts. Rainfall totals have been impressive today, with many areas seeing 2 to 4 inches, mainly across Rhode Island and southeast Massachusetts. The Flash Flood Watch remains in effect through 6 PM. While the heaviest rain is over, light to moderate showers linger and could still lead to nuisance flooding. Expect these showers to continue for the next couple of hours before wrapping up between 4 PM and 6 PM, though a few may linger an additional hour or so across the outer Cape.
Drier conditions arrive overnight, though low clouds and areas of fog may persist into early Monday morning. A final push of showers is possible toward daybreak, though guidance has generally shown this activity weakening as it approaches southern New England, leaving just a spotty shower or two, mainly in the 4 AM to 8 AM time frame. It is worth mentioning that some of the high-resolution guidance indicates a bit of a resurgence in shower activity as it approaches the coast, possibly picking up on some instability near the shore. Nevertheless, this would not lead to impactful weather and would be nothing like what we saw today.
KEY MESSAGE 2...Dry and fall-like Monday into Tuesday, with a chilly start Tuesday morning.
Surface high pressure around 1020-1025 mb builds in from the Great Lakes region on Monday, settles overhead Monday night, and remains with us through Tuesday as a 1030 mb surface high. Little weather to talk about during this time frame. While there is lingering moisture early Monday morning, with some areas of fog, a much drier airmass arrives by noon as PWATs fall below half an inch.
CAA during the day allows for a period of breezy northwest winds. Forecast soundings through BUFKIT show a well-mixed boundary layer upwards of 850 mb, which should allow most of the wind aloft to mix to the surface. Winds aloft are 25 to 30 kt, resulting in surface wind gusts of roughly 20 to 30 mph from the north-northwest. Highs Monday afternoon are largely in the lower to middle 70s.
With high pressure overhead Monday night, winds decouple, allowing for effective radiational cooling. Have opt'd to do a model blend to show the coldest of the guidance. This would mean many of us wake up Tuesday morning in the 40s; however, would not be shocked if towns in far northwestern Franklin County dip to 38 to 40 degrees. That being said, urban centers remain in the upper 40s to lower 50s. Boston may retain enough heat due to the urban heat island effect to maintain lows in the middle 50s. Lastly, there could be areas of ground fog due to the abundant recent rainfall.
Heading into Tuesday, a crisp and dry day with dew points in the 50s, with some upper 40s possible in northern Massachusetts. Meanwhile, 925 mb temperatures settle around +9C to +12C, which would suggest high temperatures in the middle 60s to lower 70s. High pressure slowly drifts east during the day, with winds shifting to a north-northeasterly direction.
KEY MESSAGE 3...High pressure in control next week brings generally quiet weather. Brief bout of summer warmth and humidity expected Wed- Fri.
High pressure firmly in control by Tuesday will bring much drier weather with it. Under dry NW flow dewpoints will be very comfortable to start the week, in the 40s. This will be a comfortable taste of Fall Tuesday when combined with high temperatures in the upper 60s (coasts) to low 70s (inland). As the high shifts over the Atlantic Wednesday flow turns southerly bringing the return of more summer- like temperatures and dewpoints in the upper 70s and mid 60s respectively. Still some uncertainty with regard to the forecast for late week and next weekend. Zonal mid level flow continues with potential for a low to cross somewhere in the vicinity of southern New England; whether that stays to our north or goes overhead is uncertain, but generally looking at a better shot of unsettled weather late Thursday onward.

.AVIATION /18Z SUNDAY THROUGH FRIDAY/... Forecaster Confidence Levels...
Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.
18z TAF Update: Widespread rain ending from west to east this afternoon.
Through 00z...Moderate confidence in trends and timing.
The heaviest rain is starting to exit from west to east across southern New England, ending first west of the CT River Valley around 19z, reaching the I-95 corridor around 21z, and moving east of Cape Cod by 00z. While much of the night will be dry, a decaying line of showers pushes through southern New England from 06z-10z. Ceilings are generally LIFR to IFR, with some improvement overnight to high-end IFR, if not MVFR. A drier airmass arrives predawn, which will erode cloud cover and allow conditions to trend VFR between 10- 14z Monday.
Monday and Monday Night...High confidence.
VFR. NW to NNW winds 8 to 12 kt with gusts 20 to 25 kt. Winds ease overnight, becoming light and variable under clear skies. Isolated areas of ground fog are possible due to abundant recent rainfall.
Tuesday...High confidence.
VFR. Light N to NNE winds, becoming E/SE by the end of the day.
KBOS Terminal...Moderate confidence in TAF.
KBDL Terminal...Moderate confidence in TAF.
Outlook /Tuesday through Friday/...
Tuesday: VFR. Breezy.
Tuesday Night through Wednesday Night: VFR.
Thursday: Mainly VFR, with local MVFR possible. Slight chance SHRA.
Thursday Night: Mainly VFR, with local MVFR possible. Chance SHRA.
Friday: VFR.

.MARINE... Forecaster Confidence Levels...
Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.
Through Tuesday...High confidence.
Surface low pressure moves northeast from the southern coastal waters Sunday afternoon, crossing into the Gulf of Maine overnight before reaching Nova Scotia Monday morning. Meanwhile, high pressure builds in from the Great Lakes region on Monday, resulting in a tightening pressure gradient and gusty northerly winds Monday afternoon through the overnight hours. There may be a brief period of gusts around 25 kt, thus a marginal Small Craft Advisory has been issued. Seas during this time are 2 to 3 ft across the nearshore waters and 3 to 4 ft across the outer waters. However, the outermost portions of the forecast zones may approach 5 ft.
Outlook /Tuesday through Friday/...
Tuesday: Winds less than 25 kt. Areas of seas approaching 5 ft.
Tuesday Night through Wednesday Night: Winds less than 25 kt. Seas locally approaching 5 ft.
Thursday: Winds less than 25 kt.
Thursday Night: Winds less than 25 kt. Chance of rain showers.
Friday: Winds less than 25 kt. Slight chance of rain showers.
