Area Forecast Discussion National Weather Service Boston/Norton MA 307 PM EDT Wed Jul 9 2025
.SYNOPSIS... Temperatures trend cooler Thursday with continued chances for showers and storms. Warmer and drier conditions return Friday, continuing through the weekend before summertime heat and humidity make a return for the start of the week along with unsettled conditions.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... Key Messages:
* Mild and cloudy with scattered showers and thunder possible
Cloudy skies expected to remain across the region with some scattered showers and thunderstorms popping up heading into the evening hours. Cloud cover is expected to build back in over the interior tonight where some clearing has occurred this afternoon. Patchy fog across southern New England may also develop overnight. Lows expected to be in the 60s for most, with some spots approaching 70 in the CT Valley and RI.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/... Key Messages:
* Showers with the potential for heavy downpours throughout the day
A quasi-stationary front makes its way to southern New England then settles in overhead. Some clearing over western parts of the interior is possible tomorrow, which could aid in providing some daytime heating that would favor convective development in the early afternoon through the evening hours. Highs in western MA and CT may reach the low 80s while the rest of the region sits in the low to mid 70s. This area is still in a Marginal risk for severe weather per SPC, but aside from that, chances for severe weather remain low. HREF thunder probs are very low across the region, though a thunderstorm or two cannot be ruled out. Onshore flow will keep the cooler and cloudier conditions over eastern MA into RI, which will help limit the convective potential over this area. Torrential downpours are more likely as PWATs remain elevated, sitting at around 1.5" to just over 2". It's worth noting WPC has southern New England under a Marginal risk for excessive rainfall as we remain under this moist and warm airmass.
For Thursday night, lows once again sit in the mid 60s with cloudy skies. Rain clears out heading into Friday as a small low to the south exits northeast.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/... Key Messages:
* Trending drier Friday through the weekend * Summertime heat and humidity return early next week, with highs in the upper 80s to low 90s possible Monday through Wednesday * Daily chances for isolated, non-severe showers and thunderstorms
Friday through Sunday
After a wet and unsettled week, well begin transitioning to drier weather Friday into the weekend as an area of high pressure settles over the coastal waters to our east. This will support east/southeast flow through Sunday, resulting in relatively cooler temperatures (upper 70s to low 80s) east of I-495 along with sunny and dry conditions.
Across the interior, temperatures will be near normal, with daily highs in the mid to upper 80s. Elevated dewpoints in the upper 60s to low 70s will support diurnal instability west of I-495, leading to a slight chance of a pop-up afternoon shower or thunderstorm across the interior this weekend.
At this time, there are no signals indicating a risk for severe thunderstorms, as weak wind fields should suppress the wind shear needed to support deep moist convection. Any storms that do develop should collapse relatively quickly. Minimal, if any, thunderstorm activity is expected across eastern areas, as onshore flow/marine air should help stabilize the atmosphere.
Monday through Wednesday
Prevailing southwest flow returns on Monday, which will support rising temperatures across southern New England. Highs will reach the mid to upper 80s on Monday. A few scattered thunderstorms may also develop across the interior, as a pulse of shortwave energy could move through the Northeast Monday afternoon.
There is still no strong signal for the presence of deep-layer wind shear needed to support severe weather, but some uncertainty remains this far out.
By Tuesday, ensemble guidance suggests increasing heat, with a 4050% chance of high temperatures exceeding 90 degrees across southern New England on both Tuesday and Wednesday. While there is no clear signal for widespread precipitation during the middle of next week, the typical slight chance for a diurnal thunderstorm remains possible.
Stay tuned for further details.

...New AVIATION...
.SHORT TERM... (Today through Monday) Issued at 1200 AM CDT Sun Jul 6 2025
Warm day as expected across the region and by late this afternoon we did have convection with the bulk of it focused across near coastal MS. Most storms dissipated by sunset and the one or two storms that were still around by 3z were right along the SELA coast.
Today and tomorrow should see more convection than we have the last 2 days. My lvl setup is transitioning to two ridges once again with the western ridge centered just south of the 4 corners already starting to build. The other ridge is east of the Bahamas while both Chantal and an mid/upper lvl low much like a TUTT low is centered over the northeastern Gulf. This TUTT will slide west over the next few days and will increase the rain chances over the area. There are some interesting details for today. We had been mentioning deeper moisture moving back in but it appears both from models and GOES19 TPW product that drier continental air will actually recycle back into the area from the northeast and east. This will have 2 impacts. First it will likely keep much of the area east of I-55 on the drier side today. That said the mid lvl dry air infiltrating should lead to slightly better lapse rates and impressive DCAPE values. In fact many of the CAMS are suggesting DCAPE values of 1200-1400 j/kg (some even greater than 1400) before convection begins to fire. Obviously CAPE is not an issue with SBCAPE expected over 3k. That said the lack of stronger mid lvl flow or deep layer shear should hinder things somewhat however given the cooling temps in the mid lvls thanks to the approaching TUTT, the mid lvl dry air working in from the east, and sufficient moisture across the western half of the CWA storms will likely develop and a few will be capable becoming strong to severe. The main concern will be damaging downbursts but can't rule out some hail given the cooler mid lvl temps (H5 temps around -8 maybe even -9C). Area with the greatest risk should be the River parishes including EBR and just to the east up to possibly I-55.
Convection will quickly start to wane over the land areas around sunset and we lose the daytime heating but convection will begin to transition more towards the marine areas. There will likely be a period of minimal activity between 1/2z and 8/9z but given the TUTT moving across the region convection likely begin to fire up quickly over the coastal waters. The question becomes how fast does that transition back to the land on Monday. Given that there is still not deep southerly flow in the LL convection likely struggles to work inland initially but with the low more on top of the area convection will probably begin to fire over the area a little earlier on Monday than Tuesday. This will lead to slightly lower instability. There may be more storms around Monday but the risk for strong to severe storms should be slightly lower.
As for rainfall, storms today should be a little more efficient than Monday. PWs looks to be on the lower end Monday with most of the CWA around 1.5-1.8 which is not anything out of the ordinary and the more efficient rain looks to be later in the week. /CAB/
&&
.LONG TERM... (Monday night through Saturday) Issued at 1200 AM CDT Sun Jul 6 2025
Medium range models continue to advertise a slightly more active pattern setting and high daily rain chance through the week. Overall the consistency in the medium range guidance, continuity between the models, and basically a slight lean towards persistence given what we have seen this Summer suggest no real deviations from the NBM.
The driest and probably warmest day of the extended portion of the forecast this package may be Tuesday. Our upper low will be much weaker as it continues to slide west into TX but the bigger influence will likely be the Atlantic ridge nosing west in the Lower MS Valley. The increase in hghts, suppression, and mid lvl temps should hurt convective potential some but this will change for the reminder of the work week.
As fast as the ridge noses in Tuesday it erodes and gets suppressed just as fast heading into Wednesday. Two things, the western ridge over the 4 corners amplifies and in response we get a trough to dig across the mid and lower MS Valley. The trough quickly erodes the western portions of the Atlantic ridge and we then move under that trough across through the rest of the week. The other things this trough is going to do is pull up rich gulf moisture and PWs begin to climb back over 2" for the 2nd half of the work week. We will also see deeper southwesterly flow in the LL across the northern Gulf and into SELA. This should allow seabreeze convection to develop a little earlier probably by late morning and start to move inland. The deeper moisture, favorable upper lvl outflow regime, and rather weak steering current will lead to efficient storms so locally heavy rain will need to be monitored especially if it falls over flood prone areas. /CAB/
&&
.AVIATION... (12Z TAFS) Issued at 633 AM CDT Sun Jul 6 2025
VFR conditions across all forecast terminals this morning. Main concern will be potential for TSRA during the afternoon and early evening hours. Most of the convection allowing model solutions keep areal coverage rather low. Will keep PROB30 groups in all terminals for this package until a definitive focus becomes apparent. Any storms that do develop will likely dissipate by about 01z Monday.
&&
.MARINE... Issued at 1200 AM CDT Sun Jul 6 2025
Still fairly quiet over the coastal waters with generally benign conditions outside of convection. Winds will remain a little more chaotic and very light until about Monday night when high pressure finally become a little more established over the eastern Gulf. High pressure then just slightly builds to the west a little through the week leading to onshore flow finally setting back up Tuesday and through the work week. On the other hand convection will likely begin to increase in coverage over the next 5 to 6 days, especially over night and through the early to mid morning hours. Waterspout potential looks like it may increase late in the week as much deeper moisture begins to move north through the Gulf. /CAB/

Area Forecast Discussion National Weather Service Indianapolis IN 1235 AM EDT Thu Jul 10 2025
.KEY MESSAGES...
- Fog possible late tonight.
- Drier weather expected on Thursday.
- Generally very warm/humid through this weekend greatest rain/ with best chance for storms late Saturday.
&&
.FORECAST UPDATE... Issued at 947 PM EDT Wed Jul 9 2025
Convection has been slow to diminish in northern and eastern zones, so have kept isolated shower/thunderstorm wording for the next 2 hrs in these areas with precip chances dropped elsewhere. For the rest of the night, as temperatures fall combined with light winds and clear skies patchy fog is expected to develop after midnight. Areas of fog are expected in valleys, especially in southern areas of Central Indiana. The rest of the forecast temps, winds and sky cover remain in good shape.
&&
.SHORT TERM (This evening through Thursday)... Issued at 330 PM EDT Wed Jul 9 2025
Surface analysis early this afternoon shows a weak, poorly defined frontal boundary across Central Indiana. Radar shows an area of showers and isolated thunderstorms over SE Indiana, associated with the passing of an upper trough. Meanwhile convective temperatures are being touched allowing a few isolated showers to develop in NW Central Indiana. All of these echos were continuing a slow eastward progression. Water Vapor showed a plume of moisture streaming across the SE 1/2 of Indiana, and subsidence across the northwest parts of Central Indiana, marking the relative position of the upper trough progressing across the area. Winds remained light and variable across the forecast area due to the weak and poorly defined pressure gradient across the area. Dew point temperatures remained quite high in the middle 60s to around 70.
Late this afternoon, diurnal heating may still allow a few isolated pop-up showers or storms across Central Indiana in the wake of the trough. HRRR continues to depict this, but most locations will remain dry. Some low chance pops will be needed through the afternoon.
Tonight...
The trough axis will continue to depart to the east, allowing subsidence to build across Indiana. This will result in clearing skies through the evening and into the overnight hours. Forecast soundings overnight show a dry column and winds are expected to become light to calm. This may result in some patchy/areas of fog toward daybreak as dew point depressions will become small. Given our current dew points, lows are expected to fall to the middle and upper 60s.
Thursday -
Models suggest that upper ridging in place over the northern plains and upper midwest will continue build slowly east, but this will still result in lee side subsidence and NW flow across Indiana. Meanwhile at the surface, weak but broad high pressure stretching from the Great Lakes across Indiana to Arkansas will be in place. Forecast soundings show a dry column through the day with very dry mid and upper levels. However, some hint of lower level CU development are suggested as convective temperatures are reached. Thus after a foggy start, skies should become partly cloudy with warm temperatures by afternoon. Look for highs in the middle to upper 80s.
&&
.LONG TERM (Thursday night through Wednesday)... Issued at 330 PM EDT Wed Jul 9 2025
Overall typical midsummer weather is expected through the long term as generally warm and humid conditions with mostly scattered, diurnally-driven convection expected for much of the period.
Aloft, troughing with embedded short waves will bring chances for rain for the end of the week and into the weekend. Friday's chances are mainly for the afternoon while better forcing later in the day Saturday bring best chances for precip in the long term. Above normal PWATs are expected for late Saturday, so could see some localized flooding potential within heavy showers or should storms pass over the same area numerous times. Also can't rule out a few stronger storms producing higher wind gusts; otherwise, widespread severe weather is not expected at this time.
Global models have been slowing the exit of the rain as a boundary looks to linger over the region, so could see storms continue through the day Sunday. High pressure still looks to bring a brief break in precipitation early next week before another upper wave returns midweek, bringing additional storms and continued warmth.
Aside from the near normal mid 80s high temps early next week, slightly above normal highs are expected, upper 80s to near 90, while overnight lows will be in the 60s and 70s.
&&
.AVIATION (06Z TAF Issuance)... Issued at 1235 AM EDT Thu Jul 10 2025
Impacts:
- Brief IFR/LIFR conditions in fog likely towards sunrise Thursday, especially in low lying areas near KBMG, KLAF and KHUF
Discussion:
Isolated convection and most clouds have largely diminished early this morning...leaving mainly clear skies with near calm winds. With abundant moisture still present in the near surface layer...the setup for areas of fog to develop looks favorable over the next several hours. Potential is there for visibilities to briefly fall below 1SM at the outlying terminals in the predawn through daybreak before fog dissipates quickly as the morning progresses.
Weak high pressure over the region will enable drier air to make a brief appearance over central Indiana later today. While diurnal cu will form into the afternoon...the presence of a mid level cap will likely be sufficient to keep much if any showers from forming late day. Cu will diminish near sunset.
