Aikyam-Lab/Synoptic-Bench huggingface dataset:
The most organized areas of light rain are exiting to the south, while a few sprinkles may be lingering to the north as the mid/upper level low pressure system continues to exit our region this evening. Cloud cover could play a role in limiting radiation conditions despite building surface ridging/lighter winds and much colder air aloft (-4 to -6C at 850MB). Despite the insulation lows should still drop below freezing, and where there are consistent breaks lows have a chance (25%) to drop below 20 by daybreak Saturday morning. Lingering light rain is possible this evening, mainly south of Highway 200 as an upper low continues working to the southeast.
Gusty west to northwest winds to around 25 mph this afternoon for windprone areas and ridgetops to the east of Tucson as we experience the fringe of a disturbance passing over the central Rockies. However, overall few impacts anticipated from these cooler temperatures as they should remain above freezing.
614 PM CDT Fri Oct 31 2025 Updated at 613 PM CDT Fri Oct 31 2025 - Cooler and a bit breezy on Saturday behind an early-day cold front.
333 PM MDT Fri Oct 31 2025 - Cooler than normal temperatures east of the Divide and near to above normal temperatures west of the Divide this afternoon.
633 PM CDT Fri Oct 31 2025 Updated at 619 PM CDT Fri Oct 31 2025 - A storm system and cold front affect the region tonight into Saturday, bringing low rain chances, as well as a brief period of below normal temperatures.
A dirty ridge remains over the Pacific NW with high clouds from a system offshore spilling over and into our area.
High pressure will continue to build from the west northwest through Tonight. Due to subsidence under the ridge, skies will be clear. Lows Tonight will range from the mid to upper 30s inland with patchy frost possible, to around 50 for coastal communities due to proximity of warmer Atlantic waters.
606 PM CDT Fri Oct 31 2025 Updated at 603 PM CDT Fri Oct 31 2025 - Seasonably warm temperatures continue today before a cold front drops temperatures several degrees below normal for this time of year on Saturday.
909 PM EDT Fri Oct 31 2025 Gusty winds come to an end tonight as high pressure builds into the region.
637 PM CDT Fri Oct 31 2025 Updated at 620 PM CDT Fri Oct 31 2025 - Dry conditions will remain through this evening with highs in the low to mid 60s.
643 PM CDT Fri Oct 31 2025 Updated at 638 PM CDT Fri Oct 31 2025 - A cold front brings a low chance for rain showers and cooler temperatures on Saturday. (Rest of today and tonight) Mid-level heights will decrease today as a mid-level trough pushes to the south across the Plains.
Overnight lows are forecast to range from the lower 50s west of Lake Okeechobee, and mid 50s to around 60F elsewhere, except lower 60s over most east coast metro locations closer to the urban core. There is some level of broad troughing that extends towards the Florida Peninsula in the mid-levels and upper-levels. Low temperatures Friday night will range from the low to mid 50s near the Lake O region to the low 60s for the interior and along the coasts.
Muscha (This evening through Saturday night) A parade of weak cold fronts will traverse the Panhandles through the next 7 days, appearing every other day. Dry conditions continue tomorrow and in the wake of the cold front where high temperatures will drop to below average with highs ranging from the mid 50s to the lower 60s.
- Temperatures remain cool over the weekend with highs in the low/mid 50s and lows in the low/mid 30s. The continued CAA allows temperatures to drop out around freezing Saturday night (but our growing season has ended so no headlines will be issued for this).
Saturday Night into Sunday morning, closed-low system shifts east of the Mississippi River Valley as a mid-level ridge axis shifts eastward out of the Four Corners Region into the southern Plains. H5 height falls are progged to expand into the eastern Plains, fostering the development of surface anticyclone across the Central and eastern Plains. With sunrise on Sunday and ridge axis pushing eastward, should see a push of warmer air between 925mb- 850mb which should help bump up surface temperatures back into the mid 50s. Through the middle of the week, ridge axis will slide eastward but deamplify with a series of vort maxima ejecting toughing off the Pacific Northwest Coast. This pushes the surface anticyclone center east of the area and provides south to southwesterly low-level flow and WAA.
215 AM EDT Sat Nov 1 2025 Low pressure will track northeast across the Northern Maritimes today.
* Another upper level low will rotate through this weekend bringing a slight chance of showers late Saturday and into Sunday. Thin cirrus will spread in from the west overnight, with thickening mid and high level clouds Saturday morning ahead of a sharpening upper level trough over the MS Valley. So, will continue wording of patchy frost possible but don't plan on any more significant wording given the low confidence and multiple limiting factors to more widespread concern. An upper low wobbles into the mid Mississippi River Valley by afternoon, and could bring some light rain showers into our NW and W CWA through late afternoon/early evening. A closed upper low will rotate from the mid Mississippi River Valley down to the southern Appalachians Saturday night into Sunday.
- Highs today will be in the low 50s with lows tonight into the low 30s.
UPDATE The most organized areas of light rain are exiting to the south, while a few sprinkles may be lingering to the north as the mid/upper level low pressure system continues to exit our region this evening. Cloud cover could play a role in limiting radiation conditions despite building surface ridging/lighter winds and much colder air aloft (-4 to -6C at 850MB).

Lingering light rain is possible this evening, mainly south of Highway 200 as an upper low continues working to the southeast.
-Scattered showers are anticipated over the northern half of Arkansas on Saturday associated with the passage of a cold front.
This will result in freezing wind chill values along and west of the Blue Ridge with some values as low as the mid-20s. A mid-level trough will begin to make its way toward the Mid- Atlantic. A large scale trough over the eastern CONUS was shifting through the area this morning. This support moves out later this morning, allowing for high pressure and dry weather to prevail. Gusts to 40 to 50 mph are possible for parts of the southern Blue Ridge and the western Greenbrier Valley today, where a Wind Advisory is in effect. Tonight, moderate radiational cooling will support overnight lows in the 30s, with freezing temperatures possible for the mountains and other low-lying areas.
A weak area of high pressure will drift over CPA overnight into early Sunday. However, hires model data shows an uptick in mid and high clouds downstream of closed upper low tracking southeastward across the Mid MS Valley.
High pressure then builds into the region on Sunday.
- Increasing clouds and a few showers or thunderstorms expected this afternoon ahead of a weak upper level trough and associated cold front that will move through the area this evening.
Models continue showing good agreement, tracking a strong upper level low pressure system, moving from the Midwest, south into the TN Valley today. Normal daytime temperatures will stretch back into the low 60s for some across the Tri-State and Kanawha Valley areas, while remaining in the 40s/50s elsewhere. Lows will range from the lower 40s across the southern lowlands, into the mid to upper 30s north and east.
As such, tonight should be slightly cooler compared to this morning. With the southern system, can't rule out the chance for sprinkles and even some isolated light rain by the end of the day but models show dry air near the surface here so confidence is on the lower end.
Updated at 1221 AM CDT Sat Nov 1 2025 - Cool weather is expected today, with dry and warmer weather forecast Sunday and beyond. At the surface, the attendant cold front was moving through the CWA, with brisk, northerly winds trailing behind. The combination of CAA and strong subsidence aloft will keep high temperatures a few degrees below seasonal norms, with highs peaking in the lower-middle 60s amidst full insolation.
212 AM EDT Sat Nov 1 2025 Below normal temperatures and dry weather should continue through Sunday morning as high pressure builds across the Carolinas. Low pressure developing off the coast Sunday afternoon and Sunday night could bring rain.
- Warmer and continued dry conditions are expected through the weekend.
A weak backdoor cold front moves in on Saturday, bringing some cooler air and modestly breezy winds for west slopes. High temps will be 5-10 degrees cooler than Fri along and E of the RGV.
The main story today and through the weekend, however, will be the persistent influence of high pressure over the region. Current 500 mb RAP analysis places the axis of a high amplitude ridge approximately along the West Coast. Ensembles show the ridge axis shifting eastward over the weekend, with H5 heights over the forecast area increasing from ~584 dam this afternoon to a peak of around 590 dam late Saturday/early Sunday as the ridge axis passes directly overhead. Despite the increasing heights aloft, the relatively short residence time of those peak values will mean that thermal profiles do not have much time to respond, and daily highs should be fairly stable in a 5-8 degree above normal range (in the upper 80s to around 90F for the typically warmer lower desert locales.
The upper low that brought us a dreary Halloween is now over northeast Iowa. It's now November, so it shouldn't be a surprise that the stratus field in the wake of the upper low is expansive. As a result, we are expecting cloudy skies today, which will hold highs back into the low to mid 40s.
(This afternoon through Saturday) With quasi-zonal flow overspreading the Southeast at the mid- levels and high pressure nudging eastward at the surface, expect mild and tranquil conditions to continue. Highs this afternoon will be warmer than yesterday under abundant sunshine, in the mid-50s to mid-60s. Lows tonight will be cooler still, in the 30s to lower 40s areawide. Moving into Saturday proper, flow aloft will shift to the southeast ahead of an approaching digging trough. Sensible weather impacts will be minimal, supporting afternoon highs just a tick warmer -- topping out in the upper-50s to near 70 -- and increasing high clouds.
1028 PM CDT Fri Oct 31 2025 Updated at 1024 PM CDT Fri Oct 31 2025 - A cold front brings a low chance for rain showers and cooler temperatures on Saturday. (Rest of today and tonight) Mid-level heights will decrease today as a mid-level trough pushes to the south across the Plains.
WEATHER PATTERN OVERVIEW: A surface warm front will move through the area this morning to bring temperatures above normal today. Then a cold front will move through tonight to bring west to northwest winds up quite a bit on Sunday.
200 AM EDT Sat Nov 01 2025 High pressure will dominate through most of the weekend, moving offshore Sunday.
1013 PM CDT Fri Oct 31 2025 Updated at 1013 PM CDT Fri Oct 31 2025 - Seasonably warm temperatures continue today before a cold front drops temperatures several degrees below normal for this time of year on Saturday.
- Much cooler and drier air continues into the weekend.
This will support some passing cirrus as well as warmer conds, esp the western third where the warmest temps will be.
This round of cloud cover will move out later this afternoon and highs today will warm into the mid and upper 50s in the upper Snake River Plain and low to mid 60s in the lower Snake River Plain and eastern Magic Valley. Winds will be more noticeable today with gusts ranging from 15 to 20 mph for many, but expect stronger gusts closer to 20 to 25 mph farther north around Stanley, Challis, Spencer, and Island Park as a cold front approaches from the northwest this evening. This cold front gets held up a bit in the Central Mountains and along the Montana/Idaho state line tonight, which is where we will see the most impacts.
This was largely driven by pressure rises behind a passing cold front. Overnight lows in these areas will only marginally touch the freezing mark and as a result, no impacts are anticipated given antecedent warm grounds.
Global models tend to show the highest amounts, while higher-resolution guidance has trended drier in recent runs. There will be enough sunshine early to allow for a quick climb into the low to mid 50s before leveling off. Likewise, lows tonight will be warmest across the south where clouds linger and cooler to the north with earlier clearing. Temperatures near freezing are possible across our far northwest.
(Tonight through Sunday night) The broad scale weather system will slowly move eastward today and Sunday allowing a broad ridge to slowly settle across the southern plains. This will keep the temperatures below normal today with morning lows starting off around freezing. Once the panhandles falls under the influence of the ridge of high pressure on Sunday the cold northerly flow will end.
Updated at 1014 PM CDT Fri Oct 31 2025 - Dry conditions will remain through Saturday morning with highs in the low to mid 60s.
Ridging should start to build back across the region by Saturday, leading to a robust warming trend for the weekend. Highs tomorrow should get into the low 60s with generally light winds. By Sunday, a pretty impressive mid-level thermal ridge should be directly over the region, with zonal flow aloft also aiding in some weak downslope.
Looking upstream, several lobes of vorticity are rotating around the large upper trof to our north, and the second and most significant of these waves will moving over our area tonight and Saturday. Under more extensive clouds tonight, lows in in the lower to mid 30s should be common through out the CWA. The fast zonal flow will keep any moisture return from being established ahead of the quickly passing warm/cold fronts, thus a dry period is expected, with little fog potential.
- Rain chances increase Sunday afternoon and Sunday night associated with the next cold front. Forecast model soundings show a light onshore flow will develop above the boundary layer but as long as a light NW drainage flow can develop, coastal sections will also drop back into the low and mid 50s, except holding in the upper 50s/near 60 Martin coast. Dry conditions will continue Sat as high pressure scoots eastward across the southeast U. A little less wind and a little warmer with max temps in the mid to upper 70s. A cut-off upper low will dig southward Sat night and Sun over the MS Valley.
A small disturbance off the southern CA coast may track inland Sunday, but the main impact will be cooler temperatures, albeit not much cooler.
Looking at the rest of the day, quieter conditions should return as surface ridging moves in to replace the departing ULL. With lingering CAA aloft and light northwesterly surface winds, another cool day is expected as highs peak in the low to mid 40s as cloud cover gradually diminishes from west to east.
This will result in freezing wind chill values along and west of the Blue Ridge with some values as low as the mid-20s. A mid-level trough will begin to make its way toward the Mid- Atlantic.
Will remain dry elsewhere with lows mainly 30s mountains to lower 40s valleys with increasing cloud cover keeping lows significantly warmer.
Updated at 1255 AM CDT Sat Nov 1 2025 - A cold front brings a low chance for light rain showers and cooler temperatures on Saturday. (Through Saturday) Cooler weather, with low chances for light rain/sprinkles, will greet us as we begin November 2025. Early morning water vapor imagery captures a southward-advancing upper low across portions of the Central Plains. An attendant cold front continues to advance southward across northern Oklahoma at this hour. Cooler temperatures and clearing skies will be left in the wake of the front by this afternoon and evening.
Upper level low is slowly moving south across the region this morning. This will bring cloudy skies to the area and cooler temps. Cyclonic flow behind the upper level low will help to form showers across the area today. We will need to keep an eye on this, as this could lead to some freezing fog. At the beginning of the period, upper level ridging builds into the area. We remain close to this ridge through the period.
High pressure remains in control of our weather through the weekend with generally light winds and temperatures around 5-15 degrees above normal.
- Below average temperatures today and tonight, with near to below freezing temperatures supporting the potential for a widespread freeze tonight into early Sunday. PRECIPITATION CHANCES: A deep upper trough and associated deep cold frontal zone currently dropping south-southeast across the region will be the focus for areas of sprinkles and light rain showers over southeast Kansas through about sunrise this morning.
557 AM EDT Sat Nov 1 2025 Below normal temperatures and dry weather should continue through Sunday morning as high pressure builds across the Carolinas. Low pressure developing off the coast Sunday afternoon and Sunday night could bring rain.
/Issued 348 AM MDT Sat Nov 1 2025/ - Meteorological Overview: An upper level trof is going to slowly move across MT over the next few days. Even though the trof is slow moving, very strong winds will occur aloft. On Sunday, the upper level trof will be pushing to our east, allowing for cooler air to move back into the CWA.
706 AM EDT Sat Nov 1 2025 - Much cooler and drier air continues into the weekend.
The upper level low that brought precipitation to areas across the region over the past 24 hours has dove south and eastward towards the Missouri/Iowa/Illinois border. Meanwhile upstream ridging is apparent on water vapor, which will build in for the weekend. Thereafter, temperatures will drop a few degrees as a low traveling across the southern Canadian Prairies drags its attendant cold front through this FA. Temperatures will remain fairly consistent ranging from the 40s to 50s for highs all week, as zonal flow/broad ridging sets up over the central CONUS. By late week, troughing over the Great Lakes will set up some form of northwest flow over the Northern Plains.
High pressure will continue to bring calm weather to the CWA with weak inversions likely across northern UT valleys through midweek.
(Today) High pressure overhead has resulted in clear skies and light winds this morning. A cold front is approaching the area from the NW today. A brief window of WAA in response to SW flow ahead of the cold front will help raise afternoon temperatures into the lower 60s, despite the cloud cover.
622 AM CDT Sat Nov 1 2025 Updated at 622 AM CDT Sat Nov 1 2025 - Dry conditions will remain through Saturday morning with highs in the low to mid 60s.
Unfortunately any sunshine currently present will be short lived as overcast conditions can already be seen infiltrating NW AL ahead of a cold front. The approaching surface cold front associated with a deep mid level cut off low will be our main weather feature through the remainder of the near term forecast. Along and ahead of the approaching front, light SW surface winds will provide some WAA and allow temps to rise into the low 60s despite the overcast skies. The overcast conditions will keep temps much warmer than previous night with morning lows in the mid 40s.
Meanwhile the western and central areas continue to be mostly cloudy ahead of the trough and warm front. Current surface analysis shows high settled through the northern and central plains while low remains over eastern Alberta and a lee side trough remains settled to the east of the northern Rockies. Upper level analysis shows ridge over the northwestern CONUS, with compact low dropping from Minnesota into Iowa. For today, a quiet day is on tap with temperatures starting to rebound as warmer air tries to push in with the upper ridge pushing easterly. Generally westerly flow sets up over the area to start the work week before a ridge passes over mid-week.
622 AM CDT Sat Nov 1 2025 Updated at 618 AM CDT Sat Nov 1 2025 - A cold front brings a low chance for light rain showers and cooler temperatures on Saturday. (Through Saturday) Cooler weather, with low chances for light rain/sprinkles, will greet us as we begin November 2025. Early morning water vapor imagery captures a southward-advancing upper low across portions of the Central Plains. An attendant cold front continues to advance southward across northern Oklahoma at this hour. Cooler temperatures and clearing skies will be left in the wake of the front by this afternoon and evening.
As large scale troughing continues to work into the West, the overall 500mb pattern will begin to flatten tonight into Sunday, bringing increasing mid-level winds (40-60 kts at 700 mb), tightening pressure gradients (12-15mb IDA-LWT), cooler temperatures, and shower chances (10-40%). Pressure gradients favor the Livingston to Nye areas this evening into Sunday morning, spreading into the Big Timber and Melville foothill areas tonight as well, ahead of an approaching cold front. As the cold front approaches from the west and northwest, areas farther north along US-191 (Harlowton) will become favored for gap winds by Sunday afternoon. Temperatures in the 50s are forecast for Sunday, a good 5 to 10 degrees cooler than today.
635 AM CDT Sat Nov 1 2025 -Scattered showers are anticipated over the northern half of Arkansas on Saturday associated with the passage of a cold front.
536 AM CDT Sat Nov 1 2025 - Low rain chances (20-40%) for the Hill Country and along and east of Hwy 281 Saturday as another cold front moves through the region. There shouldn't be many low clouds at daybreak, but the late morning should see some developing fair weather cumulus and some mid level clouds rolling in from the north with the arrival of a reinforcing cold front.
