Aikyam-Lab/Synoptic-Bench huggingface dataset:
- Cooler to near normal temperatures and dry weather is expected Wednesday through the rest of the week. High pressure sprawled out over the Canadian Prairies is extending ridging into the northern tier of the US. This feature moves into the Lower Midwest Thursday, with associated cloud cover drifting away - but smoke from upstream wildfires will continue to lead to hazy, filtered sunshine today through Thursday. Expect highs ranging in the lower to mid 70s - though locations closer to Lake Superior may struggle to get out of the 60s with northerly flow. Temperatures tonight fall back into the mid/upper 40s inland and the lower 50s near the shorelines of the Great Lakes.
The highest chance for flooding is for the northern combined Panhandles. Temperatures behind the cold front will be cooler on Thursday, and should stay in the 70's to 80's range through the afternoon.
Heat Advisory in effect today for Heat Indices in the low 100s up to 107 degrees.
* Cooler temperatures expected to arrive on Thursday and continue into the weekend.
- Shower and thunderstorm chances increase on Thursday ahead of a cold front.
1223 AM CDT Wed Jul 30 2025 - Hottest ambient temperatures continue midweek but the drier air helps to limit peak heat indices, and the overall heat risk - Higher humidity levels with low (20-40%) rain and storm chances returns late in the week through the weekend (Tonight through Wednesday night) A 598 dam subtropical ridge centered not far to our north and a 200 mb TUTT low southwest of the Rio Grande Valley will help to yield some of the driest air of the Summer so far across our region from today into Wednesday. Tonight should feel a bit more refreshing than most summer nights with overnight lows dipping as low as the mid 60s in the Hill Country to the low 70s.
Weak high pressure will remain in the region and meander over the Eastern Gulf with generally light winds and seas.
Stay weather aware! - Generally cooler than normal temperatures through the week.
- Thunderstorms will develop along a slow-moving cold front Wednesday, bringing a risk of strong storms and torrential rainfall. - Cooler and less humid air follows the frontal passage for Thursday into the weekend. Major pattern shift behind the front due to amplifying upper ridging over the Rockies and a deepening eastern CONUS trough. This to bring northwest upper flow to the region, ushering Canadian high pressure into the Great Lakes through this weekend, and a pleasant airmass we haven't seen since early June.
352 AM CDT Wed Jul 30 2025 - Cooler weather today with scattered chances for precipitation during the day. - Cooler weather continues into the weekend with highs in the 70s to low 80s. The backside of this MCS and cold front has recently exited eastern portions of the area. Much cooler weather is expected across the area aided by mostly cloudy skies and a high pressure system moving into the Midwest. Seasonably cool weather continues as highs only climb into the low to mid 70s, 10-15 degrees below normal. Dewpoints in the low to mid 60s combined with cooler temperatures will make for a fairly pleasant day, especially compared to the past few days.
Widespread rain and clouds will keep temperatures on the cool side today, with highs in the low to mid 70s. Lows will fall into the 50s and 60s as northeast winds behind a cold front usher cooler and drier air into the region. Boxell Issued 254 AM CDT Wed Jul 30 2025 Thursday through Wednesday: Cooler and dry conditions expected to build in on Thursday, continuing through the weekend as high pressure of Canadian origin sits over the Great Lakes region.
High pressure at the surface and aloft is expected to maintain dry and hot conditions across deep south Texas through next Wednesday.
Upper ridging will remained anchored to our south, while a ridge builds over the Western CONUS. A weak trough will move through the Great Lakes, dampening the ridge somewhat over the area. Given the weakening ridge, thunderstorm coverage may be a bit more today than we saw yesterday, especially given the current isolated to scattered storms moving across the region. Upper ridging will remain to our south, while the aforementioned tough digs into the TN Valley. The axis of the trough will move off the East Coast and generally remain in place through the weekend with northerly flow persisting over the local area.
Temperatures will be cooler than normal with highs ranging from the upper 70s to low 80s. A trough will continue to make its way across the western CONUS and gradually move east through the week.
Upper level high pressure will continue to sit over the region today and Thursday, which will keep mid and upper level dry air in place. Temps will continue to be several degrees above normal with highs ranging from the lower 90s across the east coast metro, to mid and upper 90s over inland and SW FL.
1046 PM CDT Tue Jul 29 2025 Updated aviation portion for 06Z TAF issuance - A cold front will move across northeast Wisconsin this evening, bringing a chance of showers and thunderstorms, though widespread severe weather is not anticipated.
(Today through Thursday) Some of the hottest temperatures of the week are expected this afternoon as a robust ridge is in place over the South Central US. The mid- level ridge shifts west tonight into Thursday allowing for an inverted trough to move over the Texas coast. Highs on Thursday will be similar to those of this afternoon, though the trough will bring back moisture to the area allowing for higher heat index values tomorrow. Rain chances with this trough remain confined to the coast Thursday keeping a dry forecast in the short term period.
High pressure remains centered off to the west, keeping hot/humid conditions over the area.
Locations close to marine environments will remain in the low 50s.
- Hot and dry conditions persist across the lower elevations through most of the forecast period, with localized critical fire weather returning Thursday. These stronger gusts look to primarily occur north of I-70, as the greatest winds aloft occur over this region, and the westward propagation of a trough increases the pressure gradient here as well.
While ongoing convection has muddled surface observations, a strong wind shift observed along this trough seen through south-central Minnesota with a secondary less noticeable boundary strewn zonally along the Iowa/Minnesota border. The zonally oriented boundary and its upper level jet streak will act to stave heaviest rainfall south while the inverted SW-NE trough and associated baroclinic gradient will try to break north. Rainfall Amounts & Location: An eventual pivot to the low results in a quasi-zonally oriented precipitation maxima of 0. Limiting factors in overall confidence include the narrow nature of band, overall residence time dependent on timing of trough, and highest model confidence to the south.
The one thing that does stand out about these storms are the higher bases with a LFC around 9-10k feet AGL over forecast points east of the Cascades. That is usually good enough to push storms off the higher mountains and into locations west of the Cascades.
There is concern that this cloud cover combined with the southward moving cold front could keep temperatures a bit cooler than the current forecast high across the north this afternoon. The highest chance for flooding is for the northern combined Panhandles. Temperatures behind the cold front will be cooler on Thursday, and should stay in the 70's to 80's range through the afternoon.
624 AM CDT Wed Jul 30 2025 - Very hot conditions will persist today underneath a high pressure ridge. - Starting this afternoon through the end of the week, increasing rain chances are expected as a weak trough arrives and lingers within an airmass of deep tropical moisture over the northern Gulf thus prompting a Marginal Risk of excessive rainfall.
- Temperatures remain near to slightly cooler than average. A weak axis of upper level ridging exists across the area between stronger upper ridging developing across western Canada and the larger scale ridge in place across the S-central US.
322 AM MDT Wed Jul 30 2025 - Cooler temperatures and scattered late afternoon/evening thunderstorms are expected through the duration of the work week. This morning, the 500 mb trough that fired off the storms yesterday will slowly continue moving through the CWA to the east. This will once again help us remain cooler Thursday as temperatures look to only make it to upper 70s and lower 80s.
623 AM CDT Wed Jul 30 2025 - Cooler weather today with scattered chances for precipitation during the day. - Cooler weather continues into the weekend with highs in the 70s to low 80s. The backside of this MCS and cold front has recently exited eastern portions of the area. Much cooler weather is expected across the area aided by mostly cloudy skies and a high pressure system moving into the Midwest. Seasonably cool weather continues as highs only climb into the low to mid 70s, 10-15 degrees below normal. Dewpoints in the low to mid 60s combined with cooler temperatures will make for a fairly pleasant day, especially compared to the past few days.
- From Thursday through the weekend, a pattern change will bring cooler, drier, and more comfortable air to the region. Otherwise, the big story will be cooler and much less humid conditions and tranquil weather conditions Thursday through the weekend. The rest of the region will see lows in the 50s, with some 60 degree readings at times near the warmer waters of the bay and Lake Michigan. Despite the cooler start to the day, most days should see high temperatures close to normal.
636 AM CDT Wed Jul 30 2025 High pressure at the surface and aloft is expected to maintain dry and hot conditions across deep south Texas through next Wednesday.
728 AM EDT Wed Jul 30 2025 After one more day of warm and humid conditions, a sharp cold front will bring scattered showers and thunderstorms this afternoon, and then cooler and drier conditions.
Upper ridging will remained anchored to our south, while a ridge builds over the Western CONUS. A weak trough will move through the Great Lakes, dampening the ridge somewhat over the area. Given the weakening ridge, thunderstorm coverage may be a bit more today than we saw yesterday, especially given the current isolated to scattered storms moving across the region. Upper ridging will remain to our south, while the aforementioned tough digs into the TN Valley. The axis of the trough will move off the East Coast and generally remain in place through the weekend with northerly flow persisting over the local area. Due to the low confidence, have kept the PROB30 group, though amendments may become necessary if the coverage increases and/or the timing is quicker than currently forecast.
- Temperatures remain near to slightly cooler than average. The greatest coverage of showers and thunderstorms today will be near the higher terrain of Southwestern and Central Montana. A weak axis of upper level ridging exists across the area between stronger upper ridging developing across western Canada and the larger scale ridge in place across the S-central US.
653 AM EDT Wed Jul 30 2025 - Chance of showers/storms this afternoon/tonight - Cooler, less humid late week - Chance of showers/storms this afternoon/tonight A cold front is near I-96 and moving south. Dewpoints are in the lower 60s north of the front and near 70 south of it.
Steady, onshore zonal flow will set in behind the trough for the remainder of the work week.

Weak high pressure will remain over the region with generally light winds and slight seas.
215 PM EDT Wed Jul 30 2025 One more very warm day with mainly dry conditions ahead of a cold front that will slowly push from north to south across the region between late this afternoon and early Thursday bringing some showers and a few thunderstorms. Another cold frontal boundary will push south from Canada late this afternoon into the evening that will see temperatures drop further for late this week, as well as be the focal point for any precipitation development headed into Thursday. With mostly cloudy skies throughout the day and cooler weather behind the front, Thursday's highs will be 10-15 degF less than Wednesday remaining mostly in the low-70s Cooler and drier weather expected for late this week as 850mb temps drop into the single digits (degC) across the area, around the climatological 10th percentile for early August.
An upper ridge off the southeast US will build westward into the Gulf through late week and into the weekend.
Issued 310 PM CDT Wed Jul 30 2025 Tonight: Cooler temperatures and widespread rainfall continues across southern Wisconsin today. Weak low pressure is moving east through the Ohio River Valley today, which has placed us in the stratiform region of the rainfall. Far southeastern Wisconsin may see light rain linger into the early morning commute tomorrow as both this weak low and the high pressure behind it are at a crawling pace. Overnight lows are expected to fall into the mid 50s Patterson Issued 310 PM CDT Wed Jul 30 2025 Thursday through Wednesday: The cooler and drier conditions are on the horizon for southern Wisconsin. High pressure in the Northern Plains and Central Canada will gradually move east southeast into the Great Lakes Region starting Thursday.
Warmer and drier conditions continue with temperatures ranging from below normal to seasonal within the marine layer and seasonal to slightly above normal in the higher elevations above the marine layer. Steady, onshore zonal flow will set in behind the trough for the remainder of the work week.
1144 AM MDT Wed Jul 30 2025 - Cooler and wetter weather will prevail today and Thursday, with scattered to numerous coverage of late day showers and thunderstorms.
227 PM EDT Wed Jul 30 2025 A cold front will cross the area today into this evening.
(Rest of Today and Tonight) Persistent ridging maintains its grasp on the lower Mississippi Valley today. Once convection dissipates this evening, temperatures will fall into the low to mid 70s once again.
Canadian high pressure will set up across the region through at least the weekend, leading to dry weather, cool nights, warm days and low humidity.
- Cooler through Thursday, warmer this weekend. The ridge axis is aligned along the Rockies with a deepening western CONUS trof. broad high pressure has set up across the region, with easterly sfc winds located across the eastern part of the CWA with southerly winds across the WY counties. Surface dewpoints still remain in the low 60s. Some light SHRA have developed across our southern counties as convective temps are in the low to mid 70s with dwpts in the lower 60s. Given that the 500hpa wave still needs to round the ridge axis, am generally leaning toward the slower solutions. 850Hpa RH values still remain on the high side so expect partly to mostly cloudy skies for the most part.
- Afternoon highs a little cooler in the 80s and 90s throughout the Valley as high temperatures drop several degrees below normal.
Heat Advisory remains in effect through this afternoon with heat indices in the low 100s up to 106 degrees.
- Much cooler, below seasonal temperatures expected tomorrow into the weekend. The HRRR develops storms along a H925 cold front just south of I-70. If storms develop in our area, the low-level jet could support support storm formation into the morning hours on Thursday. For Thursday, expect much cooler temperatures on the backside of the cold front.
The synoptic scale pattern this afternoon features a strong ridge of high pressure in the mid and upper levels located across the Southern Plains and extending into the Midwest and TN Valley. Closer to the surface, high pressure can be found along the TX Coast, with weak low pressure centered over the MS/AL vicinity, with weak troughing located in its vicinity. Temperatures in the low to mid 90s with dewpoints in the mid to upper 70s are largely responsible for this unstable environment and generally expect thunderstorm coverage to increase through the afternoon fairly quickly.
Temperatures west of the mountains will continue to be near average through the weekend, with highs in the low desert up to 5 degrees above average. Highs today are expected to be 3 to 5 degrees warmer than yesterday for most locations. There will be minimal changes in the high temperatures into the weekend, keeping conditions near or slightly above the seasonal average.
Freezing heights are still pretty high so hail does not look like much of a threat outside some pea-sized hail.
Updated at 1252 PM CDT Wed Jul 30 2025 - A low (10-30%) chance of thunderstorms are possible most afternoons, mainly over the higher elevations of the Davis, Guadalupe, and Sacramento Mountains and immediately adjacent plains.
Wildfire smoke continues to bring occasional reduced visibility to portions of the region, with the highest concentrations in northwest Minnesota.
- Showers and thunderstorms are likely this afternoon and evening along and ahead of cold front and/or convectively induced outflow boundary.
- Much cooler weather will move into the area tonight and last through this weekend. For the remainder of the night, the synoptic cold front continues to make gradual progress southward, ushering in much cooler temperatures to the region. Isolated to widely scattered showers are possible overnight tonight into Thursday morning, with the best chances centered in/near the 850-hPa cold front. Behind the surface cold front, look for northerly winds to increase to around 10-15 mph, with widespread low stratus enveloping the area.
Upper ridging persists over the central plains ahead of an upper trough meandering along the west coast. There does appear to be some weak waves moving through the ridge axis however the next couple of days.
