Area Forecast Discussion National Weather Service Pittsburgh PA 147 AM EDT Sat Oct 11 2025
.SYNOPSIS... High pressure over New England continues dry and cool conditions through Saturday. Rain chances rise Saturday night and remain through the early week especially across the eastern ridges as a weakening Great Lakes low combines with a developing coastal storm.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/... KEY MESSAGES:
- Increasing cloud cover and southerly flow will lead to warmer overnight temperatures than previous nights. ---------------------------------------------------------------
An upper level situated just north of Michigan will shift southeast overnight and draw a narrow column of mid-level moisture into the forecast region. Along with a weak jet streak aloft, each will foster increasingly broken cloud cover but lack any precipitation chances. Add in subtle southerly surface flow ahead of a cold front, and the result is moderation of overnight temperature compared to previous nights. Low readings are expected to be near to just slightly below average (for reference, the average low temperature at the Pittsburgh International Airport is 45 degrees).
&&
.SHORT TERM /6 AM THIS MORNING THROUGH MONDAY/... KEY MESSAGES:
- Slight warming trend and dry conditions through Saturday. - Rainfall through Monday favors northern and eastern areas. ----------------------------------------------------------------
Our pattern begins to shift as we move through the day Saturday. At the upper levels the closed upper low from the Great Lakes slides over central PA and begins to open up as it interacts with the closed upper low over the Southeast. At the SFC, a Great Lakes low and its associated cold front begin to drown out and transfer energy to a budding coastal low climbing the Eastern Seaboard. The coastal low slowly moves north and east hindered by stubborn high pressure Sun-Mon.
These interactions look to work in tandem to lower rain chances across our region as the highest POPs and rainfall totals shift eastwards over the mountains nearer the developing coastal low. Rain chances peak across our northern tier counties late Saturday as the Great Lakes low weakens (near 30%) and then across our eastern ridge counties Sunday and Sunday night as energy transfers to the coastal low (40-60%). POPs in the Pittsburgh Metro peak between 25-40% on Sunday and quickly fall off the further west you go. At this point it looks as though northern and eastern counties see the highest chances for showers during this time. Rainfall totals are likely to be lower across our area, with most of the rain falling across our eastern counties (0.25-0.50") and then a very sharp gradient immediately west as totals decline to a few hundredths across the remainder of western PA. Instability is quite low but there could be a couple of rumbles of thunder Saturday night mainly north and east of Pittsburgh as the Great Lakes upper low slides through the area.
High temperatures on Saturday are expected to be in the middle 60s across the north with more stout cloud cover closer to the approaching trough and ramping up to the low 70s as you move farther south. The gradient in temperatures becomes more east-west oriented by Sunday as the upper trough settles across Pennsylvania. High temperatures Sunday and Monday are expected to be near normal (mainly 60s) across western PA but slightly above average (upper 60s/lower 70s) across eastern OH.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... KEY MESSAGES:
- Dry/warm weather continues into Tuesday - Uncertainty builds mid-week with large-scale pattern -------------------------------------------------------------------
A persistent ridge axis east of the Rocky Mountains, reaching into the Ohio River Valley, will bring dry weather and warmer- than-average temperatures through Tuesday.
By mid-week, it remains uncertain if a trough will form over the Great Lakes or if the ridge will stay, and long-range ensemble temperatures indicate about a 10-degree spread between the 25th and 75th percentile. Should a trough pattern dominate, freezing conditions could return, accompanied by lake-enhanced precipitation under a northwest flow.
&&
.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/... VFR conditions will continue through most of the day. Mid-level clouds in the 6-8kft range will increase for FKL/DUJ by sunrise as a weak cold front crosses the area, coincident with decaying low pressure digging across the eastern Great Lakes. Mid clouds should then spread farther southeast after sunrise.
Broad upper level ascent could result in a few scattered showers around FKL/DUJ after 11z, but given the lower probability and scattered nature, kept a PROB30 group. These shouldn't bring much in the way of restrictions with a dry sub- cloud layer making it tough for visibility-reducing showers. The best forcing should remain north of the remainder of the terminals and preclude shower mention elsewhere. Light southerly wind will veer more northerly through the morning, becoming more northeasterly by the evening.
A coastal low tracking up the eastern seaboard will return restrictions and potential for showers Sunday morning. There will likely be an east-west cutoff of to the restrictions with the highest probability lying farther east, but some uncertainty exists with how far west sufficient moisture exists.
.OUTLOOK... Restrictions and shower chances will likely linger through much of Sunday and into Monday as the coastal low lifts north. Probabilities for both ceiling restrictions and showers will remain highest farther east with an east/west cutoff likely. High pressure will build back into the region midweek.

.KEY MESSAGES...
- A weak front may bring some light showers or sprinkles to areas along and north of the Toll Road later this afternoon and evening.
- Much of the next 7 days will feature near to occasionally somewhat above normal temperatures with the warmest days likely occuring Monday and Tuesday.
&&
.DISCUSSION... Issued at 307 AM EDT Fri Oct 10 2025
Light SE flow and slowing increasing 850 mb temps seem to be keeping temperatures in check with everyone still in the low to mid 40s. Suspect frost potential will be very isolated if at all through sunrise, but no changes planned for the headlines.
Focus then shifts to a weak disturbance, currently located from SW Iowa to central Wisconsin. A broken lines of showers and even a few storms were drifting east, assisted by some elevated instability. The greatest coverage of the storms resided in SW/S central IA. With time this instability weakens as do the showers, leading to low confidence in any measurable precipitation falling in the 21Z to 3Z period as the trough approaches. Models generally confirming this with fairly saturated soundings AOA 800 mb, then a dry layer below that. As a result of these factors, pops have been lowered even more with at best low chc in the far NW. QPF will be limited to a few hundredths at best. From 6Z Sat on, a few sprinkles or light showers may linger in S lower MI.
Next feature of interest will be closed upper low which is well depicted on water vapor in SW Ontario will drop ESE, grazing NE Lake Huron by 6Z Sat and then reaching western NY by 00Z Sun. Main impacts into the weekend will be a slowing of the arrival of warmer temps and a shift in winds back to NW and N, which may stir up waves some in SE Lake MI.
Modest upper level ridging will try to bring in warmer air, at least briefly with highs in the low to mid 70s for Mon and Tue before it flattens out as a weak, moisture starved boundary drops south. Main impacts from this appear to be a return to more seasonable temps in the mid 60s and lows in the 40s.
&&
.AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 142 AM EDT Fri Oct 10 2025
VFR conditions expected at the terminals through the period, with mainly increasing high-mid level clouds to contend with. Warm air will advect in towards the late morning with a passing warm front, with E-SE flow shifting south-southwest through the period. A cold front approaches KSBN around 00z, then crosses through KFWA by Saturday morning. Light showers are possible along this front, but moisture is lacking so confidence in any specifics is low. For now, have VCSH at KSBN from 21z-03z-- though don't expect much of an impact at the terminal from these. Left out of KFWA for this issuance as best chances arrive around or just after the end of the TAF period. Will add greater detail with the 12z TAFS.

Area Forecast Discussion National Weather Service Paducah KY 130 AM CDT Sat Oct 11 2025
.KEY MESSAGES...
- High pressure will keep the next 7 days dry and seasonally mild.
&&
.DISCUSSION... Issued at 130 AM CDT Sat Oct 11 2025
Despite the Omega blocking-like pattern's hold, there are subtleties at play in the otherwise 7 day forecast of dry and seasonally mild conditions. One example is our current cloud cover associated with a subtle pva kink in the overtop-the-ridge flow. Gridded time/height cross sections suggest this ribbon of moisture manifest with the associated deck of clouds lingers into the mid morning hours before it disperses. If that holds, fog chances should lessen. But if/where breaks occur, fog can quickly become an issue, esp in our far east. We'll have to keep a close eye upon it thru daybreak but will stick with our inherited/persistence strategy nowcast for now.
The warmest temps of the period look to be in the early half of the next work week, when H5 heights peak into the 588 DM range, reflecting a 60+ DM increase from now. This will lead to a bump back into the lower 80s starting Monday but esp Tuesday and potentially bleeding into Wednesday, which by then will represent an almost 10 degree above seasonal normal high. Lows move similarly, into the mid 50s, also close to 10F above norms by then.
The high stays strong enough to maintain its predominant influence thru the remainder of next week, but does show signs of breaking down a little as low pressure presses in upon it from the west by week's end. In response, temps should retreat back a little, more solidly into the 70s for highs, but still round out a few degrees above normal on the daily. Rain chances look scarce until 200+ hours into the forecast, so perhaps before the end of the following weekend we'll see them re-emerge.
&&
.AVIATION /12Z TAFS THROUGH 12Z SUNDAY/... Issued at 130 AM CDT Sat Oct 11 2025
Current satellite trends suggest enough clear skies/scattered clouds, esp in our east, for patchy fog to offer at least temporary vsby restrictions as a potential flight hazard thru daybreak. Otherwise the forecast features a high pressure dominated pattern with SCT-BKN VFR bases generally 5-7K FT AGL thru the effective valid time of the terminal forecast package. Obviously, where clouds are more robust pre-daybreak, fog will be less of a concern; gridded time/height cross sections do hint at that potential evolution with a narrow ribbon of moisture showing thru about mid morning, after which it squeezes out with time.

Area Forecast Discussion National Weather Service Wilmington OH 1243 AM EDT Fri Oct 10 2025
.SYNOPSIS... High pressure will shift slowly east through the weekend. This will lead to dry conditions and seasonable temperatures.
&&
.NEAR TERM /THROUGH TODAY/... Weak return flow will develop across the region today as surface high pressure shifts east into the northeastern US. With a dry airmass in place, expect mostly sunny skies again today. Temperatures will be a tad warmer with afternoon highs in the upper 60s to lower 70s.
&&
.SHORT TERM /TONIGHT THROUGH 6 PM SATURDAY/... A mid level low pressure will drop slowly southeast across the Great Lakes tonight into Saturday while an associated weak surface low weakens as it moves into northern Ohio. With a lack of deeper moisture, the main effect with this system will likely just be an increase in some clouds later tonight and into the day on Saturday. Lows tonight will generally be in the 40s with highs on Saturday again in the upper 60s to lower 70s.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... The closed low will be moving off toward northeast Ohio at the start of the extended and will be in the process of being absorbed by a broader area of low pressure off of the Atlantic coastline. Closer to the surface, a weak cold front will be pulled through the region, though sensible impacts will be minor and any isolated showers will taper off by the overnight. Overnight lows fall to the mid 40s.
Meanwhile, to our northwest, a robust area of low pressure will be moving through southern Canada, allowing for continued warm air advection. Temperatures on Sunday rise to the low/mid 70s but we'll feel more warmth on Monday/Tuesday, when we reach the upper 70s while Tds reach the mid 50s again. The cold front associated with this system will be dragged across the Ohio Valley sometime on Tuesday into Wednesday, though moisture is quite limited and we likely won't see any precipitation with its passage. Behind this feature, strong continental high pressure pushes in from Canada and temperatures look to moderate back closer to seasonal norms in the upper 60s. Overall, the warmer and dry pattern looks to continue for the Extended period.
&&
.AVIATION /04Z FRIDAY THROUGH TUESDAY/... High pressure will shift slowly off to the east through tonight as an upper level disturbance drops southeast across the Great Lakes. With a dry airmass in place, expect mainly just a gradual increase in high level moisture through the TAF period. The one exception could be some river valley fog at KLUK toward daybreak.
OUTLOOK...No significant weather expected.

Area Forecast Discussion National Weather Service Boston/Norton MA 109 PM EDT Sat Oct 11 2025
.SYNOPSIS... High pressure maintains drier and colder conditions today. A coastal storm brings rain and gusty winds Sunday into Monday night, along with the minor coastal flooding and erosion. Unsettled weather will be possible through much of next week towards the eastern half of southern New England.
&&
.NEAR TERM /THROUGH TONIGHT/... Key Messages...
* Dry with near normal temperatures
High pressure continues to move offshore today, resulting in an increasing E to SE flow. Clouds this morning develop a few breaks into this afternoon. Overall, a typical quiet Fall day.
&&
.SHORT TERM /SUNDAY/... Key Messages...
* Coastal storm arrives Sunday afternoon
Not much change to the expected pattern within the latest guidance suite. Still some uncertainty with timing and how far north the main impacts will get. Do have high confidence in a measurable rainfall across our region, but will need a little more time to work out the details on how much rainfall we could actually see. Favored the slower timing for rainfall as we will have a lot of dry air to overcome.
Have the greatest confidence in widely ranging rainfall totals through Sunday. By evening, areas towards northwest MA may see very little rainfall, while areas towards Nantucket could be approaching 1 inch of rainfall. Winds will also begin increasing Sunday afternoon with a similar pattern of the highest winds towards Nantucket.
&&
.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... Key Messages:
* Coastal storm effects linger through Tuesday
* Cooler air may move in towards the end of next week following this storm with some lingering showers towards the east coast
A coastal low will continue to make its way up the eastern US coastline. It still appears like this will be a prolonged rainfall event, mainly from Sunday night into Tuesday morning. When all is done some time Tuesday, rainfall could range from around one inch towards northwest MA, to as much as 3-4 inches towards southeast MA. It's how sharp the rainfall gradient will be that remains a question. We really can use this rainfall. It's duration allays concerns about flash flooding, but we will need to watch out for poor-drainage flooding, especially where storm drains may be blocked by leaves or debris.
Winds will pick up Sunday night as this storm approaches and the pressure gradient between it and a strong Canadian high pressure tightens. Gusts close to 50 MPH will be possible over the Islands, with the Cape seeing gusts around 45 MPH; the rest of southern New England can expect gusts to 30-35 MPH. With higher confidence in these elevated winds over the Cape and Islands, continued a High Wind Watch for the islands and a Wind Advisory for Cape Cod. With the combination of higher seas and winds, some beach erosion and minor coastal flooding cannot be ruled out.
Once this storm shifts out to sea, we may start to see even cooler conditions with rain chances starting to decrease. Some guidance is indicating it expanding a bit, and as surface high pressure behind an upper level trough cutting down from Canada moves in towards Friday, the gradient between these systems may end up elevating winds slightly once more. NW winds will help advect in cooler air as well, with 925 mb temperatures sinking to 5C and lower. This would favor highs in the mid 50s to end next week.
