Aikyam-Lab/Synoptic-Bench huggingface dataset:
Interior showers and isolated thunderstorms this afternoon and early evening over the higher terrain across the eastern portion of the forecast area.
A weak cold front will move through the region today and tonight, however little to no impacts are forecast.
- A cold front will impact the area later this week bringing cooler temperatures through the weekend. Heading into the afternoon, the deep upper-level trough over the Great Basin will send waves of vorticity maxes into the CWA.
Windy conditions are expected through Friday, with gradually cooler temperatures through the weekend. A fairly strong closed low for this time of year was centered over northern California this morning.
* A low pressure system continues to bring breezy winds and below- normal temperatures to the region through Friday, along with precipitation chances in our northwestern areas.
/Issued 101 AM CDT Thu Sep 11 2025/ /Through Friday Night/ Slightly warmer conditions are expected today compared to yesterday with temperatures in the mid 90s across the board. The area of high pressure we've been tracking over the last couple of days is currently centered near the Midland area, slowly migrating to the east.
717 AM EDT Thu Sep 11 2025 Dry high pressure will persist over the region through this weekend.
644 AM EDT Thu Sep 11 2025 High pressure will dominate the weather pattern through the next seven days with dry conditions and near to above normal daytime temperatures. An upper level trough will gradually amplify while taking on a negative tilt, as its axis approaches from the west. Meanwhile, strong surface ridging will continue to build down the lee of the Appalachians, resulting in a low-level north/northeasterly flow across the area. Time/height cross-sections show sufficient moisture in the low/mid-levels to support partly to mostly cloudy skies across most of the Midlands, but sunshine should be more predominant across the CSRA. Light northeasterly winds will prevail, with lows in the lower to mid 60s except for a few upper 50s north/west.
531 AM MDT Thu Sep 11 2025 -Seasonally very warm through Friday -Isolated showers and thunderstorms through Friday with a good chance of widespread rain Friday night into the weekend 09Z upper level anaylsis has the forecast area under southwest flow, with ridge to the east and large closed low to the west. At the surface, low pressure resides across eastern Montana, with warm frontal boundary across ND, and cool frontal boundary extending southwest into Wyoming. Ahead of the low, broad southeast boundary layer flow is in place, with very mild temperatures across the forecast area at 3 AM - in the 60s to lower 70s.
644 AM EDT Thu Sep 11 2025 -High pressure will continue beautiful early fall weather today.
414 AM MDT Thu Sep 11 2025 -Seasonally very warm through Friday -Isolated showers and thunderstorms through Friday with a good chance of widespread rain Friday night into the weekend 09Z upper level anaylsis has the forecast area under southwest flow, with ridge to the east and large closed low to the west. At the surface, low pressure resides across eastern Montana, with warm frontal boundary across ND, and cool frontal boundary extending southwest into Wyoming. Ahead of the low, broad southeast boundary layer flow is in place, with very mild temperatures across the forecast area at 3 AM - in the 60s to lower 70s.
725 AM EDT Thu Sep 11 2025 As upper-level troughing deepens, high pressure will prevail at the surface into the weekend. The mid-levels will consist of troughing over the Southeast U. It'll strengthen over the entire East Coast this afternoon through the overnight in response to strong ridging over the Central Plains. At the surface, High pressure will remain firmly over the East Coast, with a stationary front well to our south and southeast. The periphery of the High will continue to dominate our weather, bringing dry conditions. Highs should range from the lower to middle 80s. Lows will range from the lower 60s far inland to the lower 70s near the beaches. Quiet conditions continue into the weekend, as upper level ridging across the eastern CONUS gradually shifts over the Atlantic.
628 AM EDT Thu Sep 11 2025 High pressure will persist through the rest of the week.
Subtropical Ridge builds over our area the remainder of this week.
638 AM CDT Thu Sep 11 2025 - Rainfall chances will increase Friday night into the weekend as an upper level trough approaches the area from the west.
/Issued 245 AM MDT Thu Sep 11 2025/ - Meteorological Overview: Today an upper-level trough is over North-central, Central, and Southwestern Montana. Due to the upper-level trough moving slightly eastward there will be greater coverage in showers and thunderstorms today than yesterday. On Friday the upper-level trough remains over North-central, Central, and Southwestern Montana and moves slightly east.
- Warmer temperatures reach the 60s and 70s most days for the forecast period. High pressure in place will allow for quiet conditions to wrap up the work week. Winds generally out of the south will help to usher in a warmer airmass, with highs ranging in the 70s.
442 AM CDT Thu Sep 11 2025 - Rainfall chances will increase Friday night into the weekend as an upper level trough approaches the area from the west.
(Today through Friday afternoon) An upper level ridge continues to sit over the Great Plains and will continue to bring above normal heat for both today and Friday. Highs will reach into the low to mid 90s for most with upper 80s in the higher terrain.
639 AM CDT Thu Sep 11 2025 Today through tonight: Upper and surface ridging will continue to prevail across the area today and this will continue through tonight. The upper ridge will strengthen over the area today and this will result in temperatures being a couple of degrees hotter, ranging from the low to mid 90s.
(Today through Friday night) We're back to quieter weather today and tomorrow as high pressure and drier air overtake the region.
631 AM EDT Thu Sep 11 2025 High pressure remains in place over the next several days, bringing mostly sunny skies and mild temperatures.
655 AM EDT Thu Sep 11 2025 High pressure will aid in quiet and predominantly dry weather through the forecast period. However, with abundant dry air above a subsidence inversion at 700mb, if any precipitation does develop in the low levels (like the CAMs are showing) it will be very light. Mostly clear skies tonight with low temps in the low 60s, potentially near 60F along and west of I-95. A mid to upr level trough approaches the eastern seaboard but with very little moisture to work with aloft, so anticipating mainly mostly sunny/clear skies, up to partly cloudy along the coast. highs in the low/mid 80s with lows in the upr 50s to mid 60s. Aforementioned upr-level trough pushes off the coast leaving continued northerly dry flow aloft in its wake.
Despite the increasing daytime highs, overnight lows will still fall back into the low 60s.
641 AM EDT Thu Sep 11 2025 A weak cold front will move through later today into tonight, bringing just some periods of clouds.
828 AM EDT Thu Sep 11 2025 Low pressure moves away today followed by high pressure which will bring sunshine and seasonably warm temperatures. Dry weather with near seasonable temperatures prevails for the rest of the week and into much of the weekend as high pressure remains over New England.
603 AM EDT Thu Sep 11 2025 A cold front will cross the region today. High pressure will then build across the region tonight into Friday night.
511 AM CDT Thu Sep 11 2025 (Today through Friday) A deep-layer ridge is encompassing the Central CONUS with expansive surface ridging extending from Canada into the Eastern CONUS. We'll actually have a mid to upper-level trough axis move across the Ohio Valley late today which will graze Central Alabama. A reinforcing shot of dry northerly flow will surge southward into the area tomorrow behind the trough axis. Highs today and tomorrow will range from the lower 90s west to upper 80s east with low afternoon humidity, and fortunately, we'll continue to experience cool mornings with lows in the 60s.
924 AM EDT Thu Sep 11 2025 High pressure will aid in quiet and predominantly dry weather through the forecast period. However, with abundant dry air above a subsidence inversion at 700mb, if any precipitation does develop in the low levels (like the CAMs are showing) it will be very light. Mostly clear skies tonight with low temps in the low 60s, potentially near 60F along and west of I-95. A mid to upr level trough approaches the eastern seaboard but with very little moisture to work with aloft, so anticipating mainly mostly sunny/clear skies, up to partly cloudy along the coast. highs in the low/mid 80s with lows in the upr 50s to mid 60s. Aforementioned upr-level trough pushes off the coast leaving continued northerly dry flow aloft in its wake.
(This evening through Friday night) Upper level high pressure continues to dominate the short term period. Tomorrow, 850 mb temperatures decrease a few degrees (in Celsius) across the combined Panhandles, leading to slightly cooler temperatures.
Exception is the normally much wetter Bear River Range with 4-6" except 6-9" on the ridge line at the 90th percentile. Since airmass remains moist and generally dominated by overall moist zonal flow related to deep western trough, forecast remains cloudy enough to limit confidence on fog development, even after a heavy wet fresh snow.
435 PM EST Sat Mar 2 2024 After some fog develops tonight, high pressure will bring dry conditions for Sunday.
A weak cold front will move into northwestern Oklahoma after midnight and bring temperatures down only slightly.
/22/ Tonight through Sunday: Overall, a warmer weather pattern is taking shape, and dense fog will continue to be a concern as we go through the near term.
The CAMs in general did better with the lower dewpoints, especially the HRRR.
Inverted trough will shift to the east taking the snow with it by midday today. Winds behind the trough will shift to the northwest this morning and increase to 20-30mph, gusting to 40mph making blowing and drifting snow the main hazard so despite precipitation ending, will likely leave the headlines in place till the current expiration time due to the blowing snow.
Southwest mid/upper flow prevails across the Central Plains while a large trough was situated over the Northern Intermountain/Pacific Northwest regions. This dry air will eventually build eastward today ahead of slow moving cold front. Average dewpoints through the depth of the mixed layer during the afternoon hours range from -3 to -9 on point forecast soundings supporting the lower HRRR dewpoint forecasts.
1230 AM EST Sun Mar 3 2024 After some fog develops tonight, high pressure will bring dry conditions for Sunday.
Should cloud cover take longer to progress north we could see much cooler lows in the mid to low 40s.
1025 PM MST Sat Mar 2 2024 145 PM MST Sat Mar 2 2024 -Windy conditions tonight and Sunday with elevated fire weather conditions -Unsettled and cooler weather starting Sunday Current surface map places low across north central Wyoming with warm front across northeast Wyoming into southwest South Dakota. Warm front will continue to lift north this afternoon/evening, with increasing southwest winds. Pressure fall/rise couplet behind cold front front peaks Sunday morning, with best pressure rises east of the area Sunday afternoon. with around an inch of snow for the higher elevations of the Black Hills. Flattish northern stream trof sits along the Canadian border through mid week with frontal boundary lingering across the area.
Otherwise continued southwest flow aloft will continue the thermal rebound, and with our neck of the woods underneath a synoptic ridge, we should have a nice mild day with no rain. Tonight more patchy fog is possible for northeastern Tennessee, clouds in the southern valley and southern Plateau may prevent fog formation and keep overnight lows a few degrees warmer.
Deep, cold, upper trough along the nw coast will develop scattered snow showers again Sunday, and latest hi-res models are consistent bringing a semi-organized band of snow showers northeastward through Harney and Malheur Counties Sunday morning, and western Idaho between noon and 4 PM MST.
235 AM EST Sun Mar 3 2024 High pressure will shift east offshore today into tonight.
1005 PM EST Sat Mar 2 2024 Rain will taper off this evening as a low pressure system departs the area.
1149 PM CST Sat Mar 2 2024 Cloud cover will increase overnight as a warm front approaches the Mid-South. High pressure will continue to build into the Mid-South on Sunday, resulting in afternoon temperatures in the mid to upper 70s.
Winds will be slightly weaker than yesterday across the forecast area as the upper level trough over the High Plains region tracks northeast into the upper Midwest early this morning. At the surface, lee troughing will continue to produce dry west to southwest winds across the forecast area today with winds ranging from 15 to 25 mph.
Deep western CONUS trough will shift east in the period with the region on the southern semi-active periphery. A cold front will slide through the region today and support breezy westerly winds, at first over SW SD early.
An upper trough, traversing eastward through our area, has helped to destabilize the column through this period. The presence of the upper trough and the deep layered ridge well northeast of our area will contribute to a gradual increase in precipitable water. Forecast soundings suggest the low level inhibition will hold steadfast through the night. Expect temperatures to bottom out in the lower 70s with dew points holding near 70.
102 AM EST Sun Mar 3 2024 Rain will taper off this evening as a low pressure system departs the area.
A post-frontal trough will support scattered showers through Sunday.
649 AM EST Sun Mar 3 2024 High pressure off to the east of the area will keep southerly flow across the region allowing for temperatures to rise well above normal.
Temperatures will warm into the lower to mid 80s, with the warmest readings across the Big Country and Concho Valley.
Cloud cover will slowly begin to move into the region tomorrow as a warm front begins to lift northward.
If this low possibility is realized, we couldn't rule out a storm or two becoming briefly strong to severe with the forecasted amounts of shear and instability in place.
448 AM EST Sun Mar 3 2024 High pressure off to the east of the area will keep southerly flow across the region allowing for temperatures to rise well above normal.
406 AM EST Sun Mar 3 2024 High pressure off to the east of the area will keep southerly flow across the region allowing for temperatures to rise well above normal.
Winds will be slightly weaker than yesterday across the forecast area as the upper level trough over the High Plains region tracks northeast into the upper Midwest early this morning. At the surface, lee troughing will continue to produce dry southwest winds across the forecast area today with winds ranging from 15 to 25 mph.
Cold front currently analyzed along a line from Gillette. Will continue the High Wind Warnings for the Laramie Range and central Laramie County through 8 AM. Will let the warnings continue for the mountains and wait for this morning's CoCoRaHS reports for the lower elevations before ending any of these headlines.
652 AM CST Sun Mar 3 2024 (Today through Monday) This AM, there is E coast surface ridging with SE flow into C AL through the short term.
Southwest mid/upper flow prevails across the Central Plains while a large trough was situated over the Northern Intermountain/Pacific Northwest regions. This dry air will eventually build eastward today ahead of slow moving cold front. Average dewpoints through the depth of the mixed layer during the afternoon hours range from -3 to -9 on point forecast soundings supporting the lower HRRR dewpoint forecasts. This is expected to result in cooler air with multiple chance for wetting rains.
Temperatures along the Island Chain are in the lower to mid 70s with dew points near 70 degrees. Marine platforms are observing east to southeast winds near 10 knots with Island Chain communities observing near 10 mph as the western periphery of high pressure over the western North Atlantic remains in control. The western periphery of high pressure over the western North Atlantic will continue to maintain east to southeast breezes along the Island Chain as well as slight rain chances. Towards mid-week, energy emerging out from the Intermountain West and into the Plains is expected to initiate an area of low pressure along the stalled boundary that has been across Florida for the past few days.
552 AM EST Sun Mar 3 2024 High pressure will briefly build across the region this afternoon through Monday.
Overnight low temperatures are forecast to average in the lower 60s tonight with highs on Monday in the mid to upper 70s.
The High Wind Warning will remain in effect through today for this area. The stronger winds (25-35 mph) will spread east across the plains of SE NM and W TX by afternoon with the highest gusts (50 mph) possible across Eddy County.
Cool and unsettled weather will continue into the first half of the week, before warmer and drier weather moves in for the latter half. Snow showers continue to push towards the south and east as the cold front progresses.
- A cold front will move across the region Monday evening and overnight with an accompanying threat for showers and thunderstorms. Early this morning, low pressure is analyzed over northern Nebraska with a tight pressure gradient in place across portions of the mid and upper Mississippi Valley. Low pressure will lift north and occlude as it moves into Canada tonight into Monday, but a cold front will push across the Upper Mississippi Valley while the tail end of the front stalls over northwestern Illinois. In addition, deep layer shear and cloud bearing flow will be largely parallel to the slow moving cold front suggesting some training may be possible.
A potent Pacific storm system will continue to bring strong winds and cooler temperatures to northern Arizona today. Fair and warmer weather returns Monday through mid week before more unsettled weather arrives by late week.
A broad trough of low pressure will be the dominant feature over the Northern Rockies for the next several days.
Heading into Monday, the pattern shifts a bit as a cold front slides into the forecast area bringing much cooler conditions (although still above normal).
(Today through Monday) This AM, there is E coast surface ridging with SE flow into C AL through the short term.
Behind the disturbance winds are going to be gusty out of the west to northwest with gusts in the 30 to 40 mph range common, and a few higher gusts likely over the higher terrain of southeast Montana into the Sheridan foothills.
A low pressure system will continue to impact our area through this evening, with more snow expected for the Sierra Nevada through this morning.
However, if clouds hang on longer than expected we will have to lower the high temperature forecast by a few degrees.
423 AM EST Sun Mar 3 2024 High pressure will briefly build across the region this afternoon through Monday.
1223 PM EST Sun Mar 3 2024 High pressure off to the east of the area will keep southerly flow across the region allowing for temperatures to rise well above normal.
Afternoon temperatures are forecast to climb into the upper 70s along the coast and into the low to mid 80s across the interior west of I-95.
A potent Pacific storm system will continue to bring strong winds and cooler temperatures to northern Arizona today. Fair and warmer weather returns Monday through mid week before more unsettled weather arrives by late week. Look for another windy day across northern Arizona as the current trough continues to move across the area. A bit warmer temperatures and much lighter winds remain in store for the early portion of the coming week.
Look for fair and warmer weather with lighter but breezy winds for Monday through mid week before more unsettled weather arrives by late week. A broad trough was located over the western states during the afternoon hours. Over the next 24 hours the trough will gradually head to the northeast, exiting Arizona.
High pressure in the western North Atlantic continues to promote light to gentle east to southeast breezes across our marine observation platforms. While a few of these showers have drifted into our northern most waters, the Keys remain on the wrong side of the trough for upper level support of precipitation. These clouds aren't hindering surface heating too much as temperatures across the island chain are currently in the upper 70s with a couple locations already hitting the forecast highs in the lower 80s. High pressure will keep wind speed and direction generally the same.
Cool and unsettled weather will continue into the first half of the week, before warmer and drier weather moves in for the latter half. /ISSUED 440 AM MST Sun Mar 3 2024/ Snow showers continue to push towards the south and east as the cold front progresses.
Warmer and drier weather finally returns late week. (This evening through Monday) Isolated to scattered rain showers and higher elevation snow showers will continue trough the day before tapering off during the overnight hours.
With increasing moisture across parts of the area, low temperatures will once again range from the mid 40s to the low 60s where higher dewpoints will keep temperatures from falling too much. Highs will range from the upper 60s in NW OK which will be behind the front to the low 80s.
Some localized fog may be possible by early Monday morning along ridgetops due to the lower ceilings, but did not have enough confidence to put in the forecast at this time.
213 PM EST Sun Mar 3 2024 High pressure off to the east of the area will keep southerly flow across the region, allowing for temperatures to rise well above normal.
Cooler SSTs with much warmer air and increasing low level moisture may maintain marine fog along the lower Texas coast further into the week.
Some breaks in the low cloud deck has allowed for pockets of warming, and southerly winds around 10 mph and higher gusts have brought in some warmer temps today with most of the area in the mid to upper 60s and even some 70s out there.
The short term progs are in good agreement with H925-850 theta-e ridging persisting through the afternoon across portions of Deep E TX into NCntrl LA/SCntrl and SE AR, which would maintain the lifting cigs longer through the afternoon than areas farther W where the drier low level air is a bit deeper, which should help to taper temps back slightly compared to areas farther W where stronger insolation/Srly winds occur.
901 AM MST Sun Mar 3 2024 MORNING UPDATE: The below mentioned inverted trough continues to move east of Glasgow as of 8AM this morning. Behind this trough passage, snowfall rates have increased across the Hi-Line this morning between Saco and Fort Peck Lake. Additionally, northwest winds behind the trough are expected to gust as high as 40 mph through this evening, so blowing snow concerns will remain across the area even after the cessation of snowfall. Inverted trough will shift to the east taking the snow with it by midday today. Winds behind the trough will shift to the northwest this morning and increase to 20-30mph, gusting to 40mph making blowing and drifting snow the main hazard so despite precipitation ending, will likely leave the headlines in place till the current expiration time due to the blowing snow.
(Tonight through Sunday) Low level moisture will continue to lift north into the area on Monday with the unseasonably warm conditions persisting ahead of approaching cold front.
Tomorrow: A trough digging to the west will mean increased upper level Southeasterly flow. Max temperatures Monday will be a few degrees warmer then Sunday, with highs reaching into the low to mid 70s.
