300 AM EST Sun Mar 2 2025 High pressure will settle into the region today, keeping temperatures well below normal. Warmer temperatures and precipitation will return through mid week ahead of an approaching low pressure system.
645 AM EST Sun Mar 2 2025 Clouds will decrease today as high pressure builds in.
716 AM EST Sun Mar 2 2025 An upper level trough over Pennsylvania will lift out later today.
Meanwhile, an elongated upper level trough continue to dig southward along the West Coast. Post- frontal showers will continue through the day as the upper level trough moves overhead. A dusting of snow is possible on some of the higher passes of Highway 36 this morning, while Scott Mountain Pass on Highway 3 could see 2-4 inches through tonight. High temperatures are expected to be up to 15 degrees cooler compared with yesterday's reading, especially across the interior. Highs are forecast to be from mid 40's to mid 50's across the valleys, and low 30's to low 40's over the ridges. Blustery Northwest winds from 25 to 35 mph have been observed along the coastal headlands and interior ridges, with locally up to 45 mph over the high terrain. Gusts from 35 to 45 mph are expected over the ridges and high terrain.
Water vapor imagery shows a deep trough pushing into California early this morning. As we progress through the day, this trough will propagate east into California and the Intermountain West.
Under the influence of high pressure that will be expanding over the region, a cooler, drier air mass will be reinforced. (Sunday through Monday night) Northerly flow and the expansion of high pressure across the Tennessee Valley will keep cooler temperatures and very dry air in place on Sunday. Dry conditions will continue through Monday night as upper ridging continues to shift east and a warming trend begins over the Tennessee Valley. Clear skies and light winds will allow lows to dip back down to near or just below the freezing mark tomorrow night, but highs should rebound back into the lower 60s across much of the area on Monday.
542 AM EST Sun Mar 2 2025 Clouds will decrease today as high pressure builds in.

423 AM PST Sun Mar 2 2025 Updated AVIATION Discussion Precipitation is ongoing and is expected to continue through today as low pressure slowly translates through the region. Amounts are not expected to warrant any hazard headlines at this time, but road conditions could be hazardous through the morning hours for some of the highways/passes at elevations around 3500ft and above. High pressure is expected to briefly build in the wake of this current upper level disturbance.
- Meteorological Overview: An upper level ridge present across the Northern Rockies today will provide one final day of warm, dry, and overall quiet weather save for some continued increased snowmelt runoff from the higher terrain. However, this ridge will degrade and move eastward this evening as an upper level trough digs into the Great Basin, which will allow cooler air to move into the area from Canada.
308 AM PST Sun Mar 2 2025 Precipitation is ongoing and is expected to continue through today as low pressure slowly translates through the region. Amounts are not expected to warrant any hazard headlines at this time, but road conditions could be hazardous through the morning hours for some of the highways/passes at elevations around 3500ft and above. High pressure is expected to briefly build in the wake of this current upper level disturbance.
Meanwhile, the low temperature for tonight is expected to be in the mid to upper 60s. Given the low confidence at this point, current forecast excludes any dense fog concerns.
618 AM EST Sun Mar 2 2025 High pressure will settle into the region today, keeping temperatures well below normal. Warmer temperatures and precipitation will return through mid week ahead of an approaching low pressure system. Meanwhile, a low amplitude mid level ridge will begin to move in from the west.

339 AM MST Sun Mar 2 2025 KEY MESSAGES: - Last day of above normal temperatures and dry weather - Cooler and active weather expected through much of the work week Today will be the last day of the ridge of high pressure causing warm and dry conditions over the Northern Rockies. A low pressure system will dig along the coast and then slide eastward across the Great Basin on Monday.
/Issued 345 AM MST Sun Mar 2 2025/ - Meteorological Overview: An upper level ridge present across the Northern Rockies today will provide one final day of warm, dry, and overall quiet weather save for some continued increased snowmelt runoff from the higher terrain. However, this ridge will degrade and move eastward this evening as an upper level trough digs into the Great Basin, which will allow cooler air to move into the area from Canada.
Farther north, a rope cloud skirting south from the Big Bend area marks the forward edge of a weak cold front progged to cross through Florida today. While slightly more of a blow than 24 hours ago, current temperatures along the island chain are in the upper 60s with still a few inland spots dropping to the lower 60s. This is due to ample dry air observed in the low levels of the environmental profile from not only our KKEY 00z sounding, but also those upstream (KMFL and KTBW). As winds lean back to their more usual southeast direction, warmer temperatures return to the forecast with highs lifting to near 80.

618 AM EST Sun Mar 2 2025 (Today through Monday) Models and sfc analyses depict broad high pressure expanding across the SE CONUS, while a very long sfc boundary stretches from the NW Atlantic, down to the central portions of the Florida peninsula and into the Gulf waters. Morning lows will range from the low 50s to around 60, warmer near the coasts.
Following one more mild, low-impact day across southeast Idaho, high pressure will shift east and surrender control to our next storm system. a split trough with a southern branch closed low tracking just to our south across NV/UT as a northern branch open trough also impinges on our forecast area from the north (and a bit later) than the southern low.
(Rest of today through Monday) A cold front has moved south of South Florida as of early this afternoon. The front will continue to move southward allowing for high pressure to build into the region from the north. Lows tonight will a little bit warmer compare to this morning with mainly mid to upper 50s over most areas except lower 60s over the east coast metro areas.
Lows are still expected to drop back to near or just below the freezing mark.
1250 PM EST Sun Mar 2 2025 High pressure will settle into the region today, keeping temperatures well below normal. Warmer temperatures and precipitation will return through mid week ahead of an approaching low pressure system. Meanwhile, a low amplitude mid level ridge will begin to move in from the west. It will be another cold night, with lows in the upper teens to the lower 20s. Highs will range from the lower 40s northeast to near 50 southwest.
(Sunday through Monday night) Northerly flow and the expansion of high pressure across the Tennessee Valley will keep cooler temperatures and very dry air in place on Sunday. Dry conditions will continue through Monday night as upper ridging continues to shift east and a warming trend begins over the Tennessee Valley. Clear skies and light winds will allow lows to dip back down to near or just below the freezing mark tomorrow night, but highs should rebound back into the lower 60s across much of the area on Monday.
The approaching weakening cold front is now entering our northern Gulf waters seen on visible satellite. In the wake of this weak front, a strong high pressure system is going to build off the East Coast which will result in breezes freshening further and veering from north to northeast eventually back to southeast by mid week. Breezes are expected to lull prior to the next cold front which seems to be more potent.
A vigorous upper trof meanwhile advances across the southwestern states, then strengthens while progressing into the southern and central Plains Monday night. Northerly surface winds over the area this afternoon become southeasterly on Monday with this evolution and bring warmer temperatures and improving moisture to the area.
Temperatures across the island chain are in the lower 70s and will warm to the mid to upper 70s through the afternoon. Tonight a weak cold front, currently in the Gulf waters west of Tampa, will push through our waters. A weak cold front will push through the Keys tonight shifting winds to the north to northeast.
A brief period of ridging will build in behind the system for the remainder of the short term period. At the surface, sprawling high pressure is currently anchored across the Ohio River Valley. The high will move east overnight and should emerge off the Mid Atlantic coast by mid Monday.
A cold front will move through as well, and Monday looks quite breezy from just east of Boise toward Twin Falls and Jerome. Local MVFR in valley rain and mountain snow in southeast OR today, spreading into SW ID along a surface cold front this evening. Surface winds: variable 10 kt or less through early afternoon, shifting to NW 5-15 kt behind a cold front and lasting through the night.
206 PM EST Sun Mar 2 2025 Chilly high pressure will settle over the East Coast tonight and Monday, then shift off the Mid Atlantic coast Monday night.
-IG /Issued 353 AM MST Sun Mar 2 2025/ - Meteorological Overview: An upper level ridge present across the Northern Rockies today will provide one final day of warm, dry, and overall quiet weather save for some continued increased snowmelt runoff from the higher terrain. However, this ridge will degrade and move eastward this evening as an upper level trough digs into the Great Basin, which will allow cooler air to move into the area from Canada.
122 PM EST Sun Mar 2 2025 Clouds will decrease today as high pressure builds in.
The track of the low across Nevada and Utah will be key, especially in the first 18-24 hours of where the main band of precipitation sets up. The Blend of Models is also struggling to come up with anything close to what some of the higher resolution models are forecasting. The idea is for the highest amounts, for now, to be across the southern and eastern highlands. This will be a warmer event which will cut down on more widespread issues with that. Temperatures will be around 10 degrees cooler Monday vs today.
Increased southerly flow will allow for moisture to increase across the region with dewpoint values approaching the lower to middle 60s across portions of Deep East Texas by the afternoon. High temperatures on Monday will average in the 60s across much of the region except for the lower 70s across Deep East Texas. an upper-low across the Central Plains with an attached trough extending south into Texas will allow for increased height falls along the Texas dryline on Monday night.
EST Sun Mar 2 2025 Chilly high pressure will settle over the East Coast tonight and Monday, then shift off the Mid Atlantic coast Monday night.

954 PM EST Sun Mar 2 2025 Dry and cool conditions will continue into Monday as high pressure moves off to the east. Warmer temperatures and precipitation will return through mid week ahead of an approaching low pressure system.
An upper level trough is moving over the region today, bringing an cool and unstable air mass. Temperatures this afternoon are running about 5 to 15 degrees cooler than this time yesterday thanks to increased cloud cover and the cooler air mass. Shower activity will diminish overnight, but linger along the coastal mountains and Cascades into early Monday as the back side of the trough exits to the east.
The weather is quiet across the forecast area as high pressure continues to slide into the Carolinas and Mid-Atlantic states. Dewpoints began the evening in the lower teens and have recovered back into the mid 20s, but this has also led to temperatures falling really quickly.
540 PM EST Sun Mar 2 2025 - Partly Cloudy and warmer on Monday.
Ahead of these clouds, temps have dropped efficiently with some sites already in the lower 40s.
Other than some minor adjustments to hourly temperatures this evening, no other changes needed at this time as it will be cooler than last night with lows falling to the 40s across the Nature coast and low/mid 50s for the remainder of the area.
518 PM CST Sun Mar 2 2025 Updated aviation portion for 00Z TAF issuance - Small chance of light freezing rain northern WI Monday night.
These systems will bring breezy to windy southwest winds, elevated fire weather conditions, cooler temperatures, and precipitation chances. As this system moves in and associated cold front pushes through, much cooler temperatures areawide with highs 10 to 15 degrees below normal. Given these cooler temperatures and gusty winds, it will certainly feel chilly. As the trough axis pushes through Monday afternoon through Monday evening, there is enough moisture and dynamics for a 20%-40% chance of valley rain and mountain snow showers north of Tucson across Pinal/Graham/Greenlee Counties.
315 PM CST Sun Mar 2 2025 Forecast discussion for routine afternoon forecast issuance - Small chance of light freezing rain northern WI Monday night.
703 PM EST Sun Mar 2 2025 Chilly high pressure will settle over the East Coast tonight and Monday, then shift off the Mid Atlantic coast Monday night.
Temperatures this morning will be below freezing for most areas in central SC and the CSRA of GA with a few spots reaching into the mid 20s. Daytime temperatures will be warmer than the previous day as the air mass moderates with highs mainly in the low 60s. A cold front will still be well west of the region, but will continue pushing eastward through the day. Ahead of this, strong warm advection should be setting up as winds increase, with afternoon highs climbing back above normal with readings in the upper 60s to the lower 70s.
(Rest of today and tonight) Showers and thunderstorms will move through the area this afternoon and evening ahead of and near the upper low moving through the Texas panhandle. But the second wave of storms moving into the forecast area from the Texas panhandle does have more instability to work with thanks to it's proximity to the cold mid-level air close to the upper-level cyclone, thus we are seeing the strong to severe thunderstorms. The moist likely timeline for severe looks to be late Monday evening and overnight Tuesday morning as the next mid-level trough moves toward the Plains.
1235 AM EST Mon Mar 3 2025 Dry and cool conditions will continue into Monday as high pressure moves off to the east. Warmer temperatures and precipitation will return through mid week ahead of an approaching low pressure system.
942 PM CST Sun Mar 2 2025 Updated aviation portion for 06Z TAF issuance - Small chance of light freezing rain northern WI Monday night.
We are waking up to cooler temperatures this morning behind a cold front that pushed through yesterday. We will have a quick warmup tomorrow as winds shift south as a response to a strong cold front that will start to push through the southeast. This will bring temperatures into the low 80's by Tuesday afternoon.
1041 PM EST Sun Mar 2 2025 Canadian High pressure builds over the region tonight, then shifts off of the East Coast on Tuesday.
330 AM EST Mon Mar 3 2025 Dry weather is expected under high pressure through Tuesday with gradually warming temperatures.
1245 AM EST Mon Mar 3 2025 Dry conditions continue as high pressure builds in before moving offshore Tuesday.
(Monday through Tuesday night) Monday will pose another risk for fire weather as dry conditions remain with high pressure to our NE. Monday night our pattern will shift as a low pressure system and associated fronts begins to make its way across the CONUS.
230 AM EST Mon Mar 3 2025 High pressure will remain in control today, gradually sliding off the coast tonight and Tuesday.
1240 AM EST Mon Mar 3 2025 Chilly high pressure will settle over the East Coast tonight and Monday, then shift off the Mid Atlantic coast Monday night.
1121 PM CST Sun Mar 2 2025 (This evening through Tuesday) To begin the period, high pressure has begun to shift east of the area as a weak low pressure system over the Central Plains moves towards the state. As this system dissipate south of the state, a strong upper level trough will dive down into the Central Plains setting the stage for unsettled weather Monday night into Tuesday across the Natural State. Right now, there is still some uncertainty on how far north we could see severe storms due to the highest instability staying in Louisiana and southern Arkansas.
The closed upper-level low pressure system will continue moving slowly eastward across Nevada this evening, bringing light rain showers along the Idaho/Nevada border with light snow above 4500 feet. As the low shifts eastward, northwesterly winds will increase, especially in the Upper Treasure Valley, where winds are forecast to reach advisory levels. Overnight temperatures will remain above freezing in the valleys, while cooler temperatures are expected tomorrow as colder air follows the departing low pressure system.
An active weather pattern will bring unsettled weather with periods of rain, strong wind, and cooler temperatures through the week and beyond.
131 AM EST Mon Mar 3 2025 Canadian High pressure builds over the region tonight, then shifts off of the East Coast on Tuesday.
Today through Tuesday night An upper-level area of low pressure over Northern Nevada will move eastward into the Great Basin this afternoon. A ridge of high pressure will move eastward over the Silver State Tuesday and Tuesday night. High temperatures throughout Northern and Central Nevada Tuesday afternoon will be around five degrees warmer than this afternoon.
Under mostly sunny skies, temperatures will warm back up into the upper 50s to lower 60s (Tonight through Tuesday night) Monday night our pattern will shift as a low pressure system and associated fronts begins to make its way across the CONUS.
219 AM EST Mon Mar 3 2025 High pressure provides dry weather through the day on Tuesday amid a warming trend.
408 AM MST Mon Mar 3 2025 KEY MESSAGES: - Cooler temperatures are expected through midweek.
414 AM MST Mon Mar 3 2025 KEY MESSAGES: - Cooler and active weather expected during the work week allowing for snow in the higher elevations. A low pressure system is currently traversing south of the region today causing scattered showers across north central Idaho into west central Montana. The higher elevations should anticipated 1 to 3 inches of snowfall which should only have minimal impacts to Lookout, Lolo and Lost Trail passes. Once again the snow will be mainly confined to the higher elevations potentially causing some minor impacts to mountain passes due to the timing of the precipitation.
Our attention will turn to the overnight hours as the main mid- level trough and attendant large scale ascent overspreads the area. Steep mid- level lapse rates associated with strong cooling aloft ahead of the the mid-level trough will promote instability roughly 1000-1500 J/kg.
While cloud cover remains over northern California and southern Oregon under the back side of an upper level trough this morning, shower activity appears minimal on radar.
957 AM EST Mon Mar 3 2025 High pressure provides dry weather through the day on Tuesday amid a warming trend.
953 AM EST Mon Mar 3 2025 High pressure centered over Pennsylvania early this morning will shift off of the East Coast later today.
