Aikyam-Lab/Synoptic-Bench huggingface dataset:
High pressure wedging down the eastern seaboard today will increase the NE-E wind flow and produce a breezy/gusty day. There is support aloft in the form of a weak nearly stationary trough as well as a developing coastal (inverted) low level trough. Rainfall amounts of 1-3" will occur with locally 4"+ and the highest amounts should occur near the coast. The tightening pressure gradient around the high pressure to the north will produce northeast to east winds 15-25mph with higher gusts esp along the coast. There will not be significant diurnal range in temps esp along the coast due to very mild low temps holding in the mid to upper 70s and max temps only in the low to mid 80s.
The large scale pattern has high pressure centered over northern Mexico into southern New Mexico, with a ridge over the southwestern United States and a Pacific storm system off the Washington coast. The Pacific low will dive southeast into central Nevada by late Friday as the high pressure ridge shifts east into Texas and the Gulf coast. The low will then shift east across the Great Basin over the weekend, with zonal flow across the desert southwest. The models indicate some of this deeper moisture will get pulled northward in advance of the approaching storm system and trough tonight into Friday. Depending upon the evolution of the moisture plume and trough axis this will be something to keep an eye on for tomorrow, mainly east of Tucson.
The highest precipitation chances can be expected over the marine zones and Coastal Bend during the weekend, with PoPs rising to around 20-50%.
Dry and warmer conditions are then expected for the remainder of the weekend. * FRIDAY: - Low pressure continues its trek through area tonight into Friday morning.
High pres ridging into the region with ENE gradient winds.
The trough will track across our area tonight into Friday, with showers lingering on Friday mainly in Lake and Modoc counties.
257 PM EDT Thu Oct 2 2025 High pressure remains stationed across the eastern seaboard through the weekend before exiting east.
1118 AM MDT Thu Oct 2 2025 - Mild to warm temperatures will continue through Friday, before a potent weather disturbance aloft and its associated cold front bring cooler and wetter weather for the weekend. With a slight increase in 700 mb temperatures, highs will be slightly warmer.
1229 PM CDT Thu Oct 2 2025 Updated at 1228 PM CDT Thu Oct 2 2025 - Dry with warmer than normal temperatures through at least this weekend.
The environment surrounding the Florida Keys is transitioning back to a more seasonal state as high pressure along the Eastern Seaboard settles in. While this does not sound all that impressive, northeasterly low level winds will help pull in residual moisture left behind by now Post-Tropical Cyclone Imelda over the Florida Peninsula and Bahamas. As high pressure along the Eastern Seaboard continues to extend south, winds will continue to freshen out of the northeast overnight. From synopsis, high pressure is slowly moving across the eastern U. This high will begin moving into the western North Atlantic later today and into the overnight and gradually build.
(This evening through Friday) Dry and warm weather will persist across West Central Texas through Friday, as a high pressure ridge aloft dominates our weather.
- Pattern change over the weekend toward cooler temperatures and increasing chances for precipitation. Current Water Vapor and upper air models show upper ridge over the Great Lakes region flattening out, as the upper trough slides over the west coast, with southwest flow over the forecast area. Upper ridge builds into the northern and central plains later today into Friday, prompting an increase in temperatures.
Temps have climbed into the low and mid 80s across the area under mostly sunny skies. As was discussed before, seeing an area of agitated cu across west central KY where a weakness in the upper ridge is noted along with some positive area between the LFC and the H6 inversion on soundings. Perhaps a few sprinkles or very light showers across our NW in the AM, otherwise quiet and dry conditions continue under the upper ridge. The upper ridge axis will steadily slide eastward through this period, so we will be starting to see the end of the dominant upper ridge by the end of the weekend.
119 PM PDT Thu Oct 2 2025 * The best chances for showers and thunderstorms continue through Friday as the low pressure system drops into the region. * Temperatures remain below average through the upcoming week, with Friday seeing the lowest temperatures along with light snow above 8000 ft on Friday morning. All due to the upper low finally moving inland this morning, while pulling a decent plume of subtropical moisture resulting in PWs increasing to 0. By Friday morning, we should be behind the axis of the trough and the cold front.
1143 AM MDT Thu Oct 2 2025 - Dry with warmer than normal conditions through Friday.
Conditions will remain cool and showery today as a low pressure system over the far northeast Pacific slowly moves southward and weakens.
126 PM PDT Thu Oct 2 2025 Cooler conditions with an uptick in winds in the mountains and deserts Friday.
940 AM PDT Thu Oct 2 2025 Cooler conditions with an uptick in winds in the mountains and deserts Friday.
Clouds will break up and begin to lift toward the end of the period as high pressure moves in from the west. Highs will be no higher than the low 70s for much of the region, with mid to high 60s for the higher populated areas. Low temperatures over the weekend in Central OR through the Wallowa's are forecasted to be near/at freezing. For precip, a the trough will continue to push east with the oncoming ridge taking more influence in the forecast.
Updated at 1121 AM CDT Thu Oct 2 2025 - Temperatures today will remain above normal with highs in the upper 80s to near 90 degrees with weekend temperatures a few degrees cooler.
Updated at 1140 AM CDT Thu Oct 2 2025 - Dry with warmer than normal temperatures through at least this weekend.
212 PM EDT Thu Oct 2 2025 High pressure will maintain dry weather through the upcoming weekend. High pressure over Quebec will drift southward to the southern New England through Friday, while maintaining dry conditions across the lower Great Lakes region and Northeast.
214 PM EDT Thu Oct 2 2025 Canadian high pressure will build across the eastern US, then offshore, through the weekend. A mid/upr-level ridge, and accompanying mid-level high/anticyclone centered in 12Z-observed upr air data over the OH Valley, will progress slowly ewd and across the srn Middle Atlantic tonight. At the surface, 1033 mb Canadian high pressure centered this afternoon over the Northeast will become centered over the Middle Atlantic tonight, while continuing to ridge swwd across the Carolinas and Southeast. * Another picture-perfect Fall Day Underneath a 588 dm ridge, Canadian high pressure will remain entrenched over the region, reinforcing a dry, stable airmass over central NC. Even so, another crisp and cool autumn night is expected, with lows in the lower to mid 50s, and some mid/upper 40s possible in more rural outlying areas.
1248 PM PDT Thu Oct 2 2025 * A low pressure system will bring gusty southwesterly wind to the region on Friday, with increased precipitation chances for the Great Basin and eastern Sierra.
617 PM CDT Thu Oct 2 2025 Updated at 609 PM CDT Thu Oct 2 2025 - Dry with warmer than normal temperatures through at least this weekend.
This will be due to the expected amplification of a weak inverted trough aligned over the Bahamas. In addition, the wind profile is not exactly favorable, being weak and backing in the lower levels and significant westerly shear begins below 500 mb. With all that said, the amplification of the lower level trough is generating good lower level confluence and has resulted in scattered showers and a few thunderstorms. Strong high pressure blanketing the eastern United States will pivot a bit further off the Atlantic Coast overnight. However, associated strong breezes will most likely remain to our north due to the expected amplification of an incoming weak inverted trough currently aligned over the Bahamas.
Broad mid-level ridging over the central part of the country has easterly flow through the lower and mid levels. A little higher around 500mb, a trapped low pressure circulation has been causing isolated shower and storm activity in the region.
639 PM CDT Thu Oct 2 2025 Updated at 636 PM CDT Thu Oct 2 2025 - Temperatures today will remain above normal with highs in the upper 80s to near 90 degrees with weekend temperatures a few degrees cooler.
506 PM MDT Thu Oct 2 2025 - Dry with warmer than normal conditions through Friday.

745 PM EDT Thu Oct 2 2025 High pressure remains stationed across the eastern seaboard through the weekend before exiting east.
607 PM EDT Thu Oct 2 2025 High pressure will maintain dry weather through the upcoming weekend.
350 PM PDT Thu Oct 2 2025 * A low pressure system will bring gusty southwesterly wind to the region on Friday, with increased precipitation chances for the Great Basin and eastern Sierra.
355 PM MDT Thu Oct 2 2025 - Dry with warmer than normal conditions through Friday.
The current pattern of surface to mid-level ridging over the area will compress and shift east this weekend as a trough pushes into the central CONUS from the west.
Redevelopment of showers on Friday afternoon look more relegated to the higher terrain and isolated at best in those areas. Cooler conditions through the weekend.
(Today through Saturday) An area of low pressure to the east of South Florida will continue to support wet and unsettled conditions across the area through the short term period. Satellite and radar imagery show the low sitting between the Florida peninsula and the Bahamas early this morning, and rain gauge data indicate the rainbands along the low dropped widespread 1-3 inches of rain across southeast FL overnight, with isolated spots up to 5 inches. Highs will top out in the upper 80s and low 90s, while overnight lows will stay in the low to mid 70s across the whole area.
1211 AM CDT Fri Oct 3 2025 Updated at 1209 AM CDT Fri Oct 3 2025 - Dry with warmer than normal temperatures through at least this weekend.
136 AM EDT Fri Oct 3 2025 High pressure remains stationed across the eastern seaboard through the weekend before exiting east.
(Today) Current temperatures are in the lower 60s across the Tennessee Valley.
- A slow moving cold front will pass through NE Montana today and tonight.
235 AM EDT Fri Oct 3 2025 Canadian high pressure will build across the eastern US, then offshore, through the weekend. Underneath a 588 dm ridge, Canadian high pressure will remain entrenched over the region, maintaining a dry and stable airmass over central NC. Forecast guidance suggests a very modest increase in low-level thicknesses, supporting highs similar to or a few degree warmers than yesterday, particularly across the Sandhills and coastal plain where stratocumulus was more pronounced yesterday. Lows in the lower to mid 50s, and some mid/upper 40s possible in more rural outlying areas. Canadian high pressure extending over the region will begin to moderate as the parent high center drifts south over the southern mid-Atlantic and DELMARVA region. Aloft, ridging and associated synoptic scale subsidence will persist.
Water vapor imagery currently shows a weak upper impulse sliding across the Mid Mississippi Valley with upper ridging through the Southern High Plains. Meanwhile, a sharp upper trough is just off of the Pacific Northwest Coast. For tonight into Fri, West Coast trough will consolidate as it sinks southeast and by Fri afternoon will be tracking across Central CA, with upper ridging remaining from Northern Mex through the Southern Plains. There is good agreement between the GFS and ECMWF in some upper energy getting cut-off over the Great Basin on Mon as the mean upper trough swings across southern Saskatchewan and into Southwest Ontario by Tue morning. This will allow a more substantial cold front to push south across the area for Tue into Wed, bringing cooler temps and increased rain chances.
257 AM EDT Fri Oct 3 2025 High pressure will maintain dry weather through the upcoming weekend.
At the same time, a high pressure that is along the eastern shoreline of the U. At the same time, the stationary front will begin lifting northward as a warm front and the winds will briefly becoming southerly. As the low travels further northwest and moves inland over Louisiana, high pressure will back into the southeast U.
- Fair weather remains with slightly above average temperatures and low (0-20%) rain chances over the next 7 days, with no significant impacts expected (Today through Saturday) Sub-tropical ridging gradually erodes into the weekend as a weak upper level low slowly begins to establish across the northern Gulf coast states/waters. This area of low pressure looks to help advance some slightly greater moisture into Texas.
Updated at 1038 PM CDT Thu Oct 2 2025 - Dry with warmer than normal temperatures through at least this weekend.
1049 PM PDT Thu Oct 2 2025 * A low pressure system will bring gusty southwest winds to the region on Friday, with increased precipitation chances for the Great Basin and eastern Sierra.
An upper level trough organizes over the north-central and northeastern Gulf coast into the weekend. A combination of better moisture levels, strong low level dynamics in the strong easterly flow, along with several easterly waves passing south of the Gulf coast, and added upper weakness from the upper trough, comes together allowing for daily showers and thunderstorms to form over these areas.
Showers and isolated thunderstorms will continue in the region through this afternoon while cooler than average temperatures prevail.
158 AM PDT Fri Oct 3 2025 * Showers will continue today as the low pressure system moves into the region. * Temperatures remain below average through the upcoming week, with today seeing the lowest temperatures along with light snow above 8000 ft. * The primary upper level low will move into the area today, with a continuation of the wet, cool weather.
643 AM EDT Fri Oct 3 2025 High pressure will maintain dry weather through the upcoming weekend.
446 AM PDT Fri Oct 3 2025 * A low pressure system will bring gusty southwest winds to the region today, with increased precipitation chances for the Great Basin and eastern Sierra.

636 AM CDT Fri Oct 3 2025 Updated at 634 AM CDT Fri Oct 3 2025 - Dry with warmer than normal temperatures through at least this weekend.
Today: Isolated Showers/Rumble of Thunder A well-defined upper level vort lobe is noted early this morning on water vapor imagery, with enough DCVA and theta-e advection ahead of the trough to spur the development of scattered showers and even a couple of weak thunderstorms over north-central Iowa. Have increased PoPs for this morning based on radar trends, but overall impacts are expected to be light and scattered in nature given the highly elevated updraft bases around 600 mb and a 15-25 C T/Td spread under these cells. This first round of showers departs to the northeast by midday with the passage of the lead upper trough.
Cloud cover and precipitation will keep high temperatures in the lower 80s, potentially upper 70s, across our far eastern zones on Wednesday.
Another quiet morning is unfolding across the CWA, with temperatures at 3am in the low to mid 50s. Afternoon highs to top out in the lower 80s. Overnight lows will drop into the lower 50s.
The low-lvl flow will remain light and sea-breeze driven today, however, there will be a light W-NW component aloft as our area remains positioned just to the NE of the mid-lvl ridge axis over the SE GOM. The pattern will not change noticeably for Wednesday with the mid- lvl ridge axis centered just southwest of the area and the front remaining draped over North-Central Florida.
Going with national blend of model temps which are mid to upper 80s today, but some possibilities exist we stay a bit cooler. At least from the HRRR smoke aloft looks quite thick today, but time will tell if thick enough to keep temps on the cooler side of fcst. A bit cooler for most areas Wednesday with a wind shift to the north and then northeast behind our current system.
Mostly sunny skies alongside 850mb WAA has warmed temps into the low to mid 70s save for near Lake Superior where the lake breeze has moderated temps, keeping them into the 60s. The ridge recovers from midweek onward, with strong positive height anomalies maximized near Hudson Bay. While many members show some QPF, confidence in this actually playing out remains low given that this weakening wave will have to contend with the stubborn ridge over the region. Light winds mainly of 20kts or lower are expected across the lake this week thanks to high pressure and a warm airmass over the region.
High pressure ridge slides eastward today as southerly flow builds into the Northland overnight. Overnight low temperatures in the low-60s are forecast tonight in the Brainerd Lakes region under elevated southeasterly winds as a low level jet slides through the southern part of the Northland into Tuesday. A deep long-wave trough over the western U.
245 AM EDT Tue Sep 10 2024 High pressure will begin to build into the region today and will last through at least mid week.
418 AM EDT Tue Sep 10 2024 High pressure will remain in control of our weather through the weekend and it will bring plentiful sunshine. Then we'll have surface and upper level high pressure continuing to build into our region, leading to fair weather through the period.
117 AM EDT Tue Sep 10 2024 - One more night of near-record low temperatures, then warmer through mid-week.
There is the low chance for showers overnight tonight but forcing is very weak so the probability is very low thanks to lower level dry air. The wave is accompanied by steady 850mb warm advection, but no low level jet, minimal 0-6km effective shear, and very dry air in the low layers. Have not really noticed it being too thick during the days, definitely not enough to result in cooler highs. Highs may be a few degrees cooler across the Devils Lake region on Wednesday (upper 70s), otherwise highs look to remain mainly in the 80s all week.
Otherwise a gradual warming trend with seasonably normal temperatures this afternoon with another cooler night (50s) across most of our area. However, increasing surface moisture transport from Tropical system Francine off the Texas Gulf Coast will start increasing into southeast Oklahoma raising those dew points keeping it slightly warmer there (lower to mid 60s) overnight. However, did go just slightly cooler than NBM default across central through southeast Oklahoma using the NBM 10th percentile for tonight's MinT.
Upper level ridging builds promoting a stagnant pattern. Weekend: An upper level trough digs into western CONUS by midweek and may bring our next best chance for precipitation. Cluster analysis shows the trough weakening and quite possibly being deflected up over the blocking pattern.
Forecast soundings aren't overly impressive with dry air in the lower levels but there should be enough forcing given steep mid-level lapse rates present. Temperatures today will warm into the low to mid 80s as the combination of cloud cover & elevated wildfire smoke suppress high temperatures a bit. Tonight's lows will be in the low to mid 60s. Highs will be in the low to mid 80s and lows in the low to mid 60s. Systems will struggle to make it further east than the Dakotas given the upper level ridge across the Great Lakes and E NOAM.
(Today) Tranquil conditions across the region for one more day as high pressure to the north continues to promote clear/dry conditions.
350 AM EDT Tue Sep 10 2024 - One more night of near-record low temperatures, then warmer through mid-week.
Lows by morning should range from the middle 50s in the Hill Country to the lower 70s in the southeast. Lows tonight will be warmer given the cloud cover, in the 60s to lower 70s across the region with the warmer values in the eastern areas.
From synopsis, weak high pressure over the western Atlantic will maintain light to gentle mainly east to southeast breezes across the Keys coastal waters through the rest of the week.
737 AM EDT Tue Sep 10 2024 High pressure and ridging aloft will keep dry weather and above average temperatures in the forecast this week. Fog will dissipate with sunrise and the stratus will erode with daytime mixing giving way to a mostly sunny sky save for some cirrus this afternoon as an increase in upper level moisture rides atop the building ridge.
Warmer than normal temperatures will persist through the work week as mostly dry weather continues. Cooler temperatures for the upcoming weekend as precipitation chances return. The sky was clear across SE AZ this morning under weak ridging aloft. Highs today will be at or a few degrees warmer than yesterday.
927 AM EDT Tue Sep 10 2024 Cool and dry weather is expected for the first half of this week as Canadian high pressure builds in from the north.
514 AM EDT Tue Sep 10 2024 Another extended stretch of rain-free weather is expected to last into the weekend with temperatures trending warmer. Ridge tops will stay 5-6F cooler. High pressure will dominate and control the sensible wx pattern through midweek. Temperatures will get 5-6F warmer on Wed (9/11) vs Tues in the N, and 2-3F warmer in the S. High pressure will remain firmly in place over the Mid-Atlantic and New England regions late this week.
Persistent high pressure and onshore flow from Lake Erie and Lake St. Once morning fog erodes, ample sunshine is expected as mid level ridging moves overhead while a large low level anticylone dominates across the Ohio Valley and eastern Great Lakes. Last evenings cold front has eroded across srn Mi. Low level thermal fields will be slightly cooler across the eastern portions of the forecast area in comparison to yesterday, warranting forecast afternoon highs of mid to upper 70s. Model soundings and latest guidance suggest the western sections of the forecast area should be able to see afternoon temps into the low 80s. Despite the resultant increase in mid/high level clouds, southerly flow circulating around the high to the east will boost afternoon temps well into the 80s.
613 AM CDT Tue Sep 10 2024 (Today and tonight) Early this morning, temperatures across west central Texas were in the upper 50s to low 60s with dewpoints around 50, indicating a dry, cooler-than-normal airmass in place. At the surface, high pressure that was centered over the Ohio Valley yesterday has lifted northeast and will have much less influence on the weather over west central Texas today. The forecast should be similar to yesterday with afternoon high temperatures in the low to mid 80s. Overnight lows should be a few degrees warmer than last night as higher dewpoints begin to creep northward into the region.
The highest winds look to remain generally west of the I-55 corridor, while the other risks look to plague the rest of the area. In terms of specific impacts, storm surge looks to be the highest west of Port Fourchon where a max inundation of 5-10 feet is possible along the coastline.
- Breezy winds this afternoon with wind gusts up to around 30 mph, the highest gusts in the northwest.
936 AM EDT Tue Sep 10 2024 A trough of low pressure will cross the northern part of the forecast area today.
506 AM EDT Tue Sep 10 2024 A trough of low pressure will remain to our north today.
