1059 AM EDT Tue Mar 11 2025 * Gusty winds ahead of a cold front this afternoon will contribute to an elevated risk of wildfire spread. * After a brief cool down on Wednesday, warmer temperatures will return late in the week and remain with us into the weekend.
Snow levels will start out between 6 and 7 thousand feet on Wednesday ahead of the cold front and drop to 5 to 6 thousand feet Wednesday.
647 AM EDT Tue Mar 11 2025 High pressure overtaking the region today will lead to sunny skies, breezy, and warm conditions across the area.
209 PM MDT Tue Mar 11 2025 - High pressure allows for warm and dry conditions through tomorrow.
Latest surface analysis shows a low pressure center spinning about 280 miles offshore of Wilmington. This low was responsible for all of the rain we experienced last night into early this morning. As the low pressure center dragged further offshore throughout the day, it took the clouds with it, allowing for widespread blue skies by around noon EDT today. Temperatures have gotten up into the lower 70s as a result. Clear skies continue tonight under high pressure, with light and variable winds expected after sunset. Nothing but sunshine ahead for Wednesday, with high pressure in the Gulf poking slightly northward. Continental flow aloft means warmer high temperatures, generally in the upper 70s inland.
143 PM EDT Tue Mar 11 2025 High pressure builds across the area today behind an exiting area of low pressure. Low pressure continues to move further offshore to the southeast, and has resulted in a completely clear sky over the last couple of hours. A potent closed mid-upper low will continue shifting increasingly offshore through the period. With plenty of subsidence and dry air in the column, expect a sunny, warm, and dry day to ensue with highs in the low to perhaps mid-70s. Lows should dip into the low-mid 40s, with some normally cooler/sheltered locations possibly dipping into the upper 30s. High pressure to our south on Wednesday will maintain very dry and quiet weather across the region.
1239 PM CDT Tue Mar 11 2025 (This afternoon through Wednesday) Top of the hour readings are in the 60s along I-20 with some cooler valley areas. Our average for mid March is generally 10 degrees cooler, so get ready for Spring to give Winter a break too.
(This afternoon through Wednesday) Top of the hour readings are in the 60s along I-20 with some cooler valley areas. Our average for mid March is generally 10 degrees cooler, so get ready for Spring to give Winter a break too.
(Now through Wednesday) Subtle upper ridging over the area moves off to the east through this evening leaving a fairly zonal flow. An upper trof advances across the south central states and moves into the southeast states late Wednesday night. Very dry air over the region this afternoon is followed by improving deep layer moisture through the period, but this appears to be insufficient to support pops through Wednesday night, despite the approaching upper trof. Lows tonight range from the mid 40s inland to the lower 50s at the coast, then Wednesday night will be milder with lows ranging from the mid 50s inland to around 60 close to the coast.
A strong high pressure in the Gulf is giving us clear and comfortable conditions this afternoon. The high pressure will shift from the Gulf to the Atlantic throughout our week.
1213 PM CDT Tue Mar 11 2025 - Cooler temperatures are expected today.
/29 (Now through Wednesday night) Subtle upper ridging over the area moves off to the east through this evening leaving a fairly zonal flow. An upper trof advances across the south central states and moves into the southeast states late Wednesday night. Very dry air over the region this afternoon is followed by improving deep layer moisture through the period, but this appears to be insufficient to support pops through Wednesday night, despite the approaching upper trof.

1203 PM CDT Tue Mar 11 2025 (Today through Wednesday) Upper troughs off the South Carolina coast and off the coast of southern California, with upper ridging over the southern Plains States. At the surface, high pressure over the western Gulf, while low pressure over the Great Lakes had a cold front southwestward into Colorado. High pressure will move eastward over the next 36 hours and extend from near Bermuda to the eastern Gulf by Wednesday evening. The trough off the southern California coast this morning will move to Oklahoma by Wednesday evening.
1238 PM CDT Tue Mar 11 2025 (Today through Wednesday) Low pressure works into the Southern Plains by mid-week, gradually strengthening the pressure gradient along the lower Texas coast into Wednesday, increasing southerly winds. Much warmer temperatures arrive on Wednesday with a stronger southerly breeze.
1222 PM CDT Tue Mar 11 2025 Updated at 1218 PM CDT Tue Mar 11 2025 - Dry and warmer conditions are expected today and Wednesday, with high temperatures reaching the mid 70s.
242 PM EDT Tue Mar 11 2025 High pressure will build across and offshore the South Atlantic states through mid-week. Temperatures should rise a few more degrees into the low to mid 70s before sunset. Tonight, high pressure over the Gulf will spread into central and southern FL.
234 PM EDT Tue Mar 11 2025 Dry high pressure continues through Wednesday with temperatures well above normal.
Various scenarios bring different hazards ranging from freezing rain to heavy snow to blizzard conditions, or some combination.
Weak high pressure will continue to drift eastward into the Florida Peninsula overnight.
(Tonight) A ridge of high pressure at the surface has shifted east allowing southerly flow to develop today.
02z ambient temperatures are some 5 to 10 degrees warmer compared to 24 hours ago and this trend will continue given the pressure gradient that is in place across the Southern Plains and Lower Miss Valley. Obviously the cooler temperatures will be in the valleys and more protected areas of our region and the current forecast has this well accounted for.
517 PM MDT Tue Mar 11 2025 - High pressure allows for warm and dry conditions through tomorrow.
651 PM EDT Tue Mar 11 2025 Dry high pressure continues through Wednesday with temperatures well above normal.
1006 PM EDT Tue Mar 11 2025 Dry high pressure continues through Wednesday with temperatures well above normal.
An upper level Low brings rain and snow across central Arizona late this evening and into Wednesday, with some snowfall accumulation above around 6500 feet.
Various scenarios bring different hazards ranging from freezing rain to heavy snow to blizzard conditions, or some combination. Any accumulations look to remain light and below an inch for areas along the Highway 2 corridor.
Beautiful clear skies to remain overnight allowing lows to drop into the low 40s to low 50s.
An upper level low will continue to bring rain, snow, and thunderstorms to central Arizona into Wednesday, with some snowfall accumulation above around 6500 feet.
151 AM EDT Wed Mar 12 2025 Very dry atmosphere and high pressure over the region will produce blue bird skies and cool temps this morning followed by warming but comfortable temps this afternoon through Thu. High pressure moves into the W Atlantic Fri into Sat with southerly flow increasing which will bring higher dew point airmass to the state with max temps climbing into the mid to upper 80s.
1240 AM CDT Wed Mar 12 2025 (Tonight) A ridge of high pressure at the surface has shifted east allowing southerly flow to develop today.
Aloft, the Florida Keys will remain under the influence of large-scale ridging, which will only grow in strength through the weekend. Meanwhile, at the surface, high pressure currently situated in the central Gulf will slide eastward into the west-central North Atlantic. This high will merge with a stronger secondary high diving southward from eastern Canada this weekend. At the same time, a strengthening area of low pressure will progress northeastward from the Rockies to the Upper Midwest.
320 AM CDT Wed Mar 12 2025 - Winter impacts are expected this weekend as a strong storm system brings freezing rain, heavy snow, strong winds, and blowing snow into the region.
1053 PM MDT Tue Mar 11 2025 - High pressure allows for warm and dry conditions through tomorrow.
Various scenarios bring different hazards ranging from freezing rain to heavy snow to blizzard conditions, or some combination. We continue to see snow move across the Highway 2 corridor this evening, with conditions slowly improving out in the Devils Lake Basin. Any accumulations look to remain light and below an inch for areas along the Highway 2 corridor.
Temperatures this morning range from the low 40s to low/mid 50s. Mixing at the higher elevations have kept temperatures elevated and some ridgetops may not dip below 50F. Bumped temperatures above NBM guidance by a couple of degrees as actual afternoon highs seem to be running on the warmer side of guidance. Lows again tonight expected to be in the mid/lower 40s in the lower elevations and valleys. Ridgetops stay warmer with continued mixing.
High pressure over the region will continue the fair dry weather with light winds becoming westerly as the sea breeze develops and moves inland this afternoon. Very dry atmosphere and high pressure over the region will produce blue bird skies and cool temps this morning followed by warming but comfortable temps this afternoon through Thu. High pressure moves into the W Atlantic Fri into Sat with southerly flow increasing which will bring higher dew point airmass to the state with max temps climbing into the mid to upper 80s.
Key Message(s): - Warmer today with clear skies and southwest winds. High pressure continues to ridge over the area today with sunny skies. Ridging strengthens over the area today which will lead to higher temperatures than yesterday with highs topping out in the upper 70s to low 80s. A mid to upper level transient trough is forecast to move across the Gulf Coast states into the Southeast on Thursday, which brings increasing clouds for the day. As a result of the clouds, temps are expected to be slightly cooler than Wednesday, but still above average. After the trough passes, ridging builds back into the area ahead of the next system progressing through the central parts of the CONUS.
A broad storm system will bring a strong cold front through the area Thursday afternoon and evening, bringing significant snow to the mountains of Utah, with strong and gusty winds anticipated over western Utah ahead of the front.
Will have one more warm and mostly dry day today with southwesterly flow aloft keeping the warm conditions going one more day ahead of a strong Pacific storm system with a strong cold front which will move through southeastern Idaho on Thursday.
330 AM MDT Wed Mar 12 2025 KEY MESSAGES: - Occasional pass level snow and slick roads, mainly overnight/early day periods throughout the week A broad low-pressure system off the West Coast will continue funneling Pacific moisture into the Northern Rockies today. However, a passing cold front will bring snow levels back down to valley floors by Thursday evening.
Highs each afternoon will peak in the low to mid 80s today, while overnight lows could drop to the low-mid 50s inland, and low 60s along the East Coast.
Dew points are also still on the lower side of things ranging from the upper 40s to the upper 50s. From synopsis, high pressure centered over the central Gulf will slide eastward through the rest of the work week.
- Winter impacts are expected this weekend as a strong storm system brings freezing rain, heavy snow, strong winds, and blowing snow into the region. West to northwest flow through tonight and tomorrow with rising heights ahead of the next main trough.
Precipitation will continue tonight in the wake of the front as an upper trough moves into the area with snow concerns expected around the Mount Shasta Area, and portions of the Eastside with moderate to strong winds in the Shasta Valley, and higher elevations east of the Cascades. Marine stratus remains locked in with low VFR/MVFR ceilings as warm moist air pushes in ahead of the cold front. As the cold front approaches, there is a low chance of low level wind shear over Roseburg this morning. A cold front will move inland this morning, with winds shifting from south to southwest and gradually diminishing.
A warm front under strong southwest flow aloft will bring showers to the area today, mainly focused over the mountains and the upper Weiser River Basin. A cold front will track across eastern OR late this afternoon and into southwest ID late tonight into Thu morning.
(Tonight through Thursday night) Key Messages: - Elevated Fire Weather expected today and tomorrow (see Fire Weather Discussion) - A Weak and Dry Cold Front this Afternoon/Evening A weak and dry cold front associated with a mid-level trough over the Southern Plains is expected to move across our CWA from west to east before stalling across the Coastal Plains starting this afternoon into tonight. Slightly cooler conditions are in store behind the front. Thursday afternoon will warm to the low to mid 90s across much of the region in response to more efficient radiational heating due to the drier air and mainly clear skies. Thursday night lows will range in the low to mid 60s across the region.
259 PM EDT Wed Mar 12 2025 - Mainly warmer than normal temperatures are expected into the weekend.
1245 PM EDT Wed Mar 12 2025 High pressure is expected to prevail through the end of the week. A cold front is expected to push through the region late in the weekend. Tonight: Dry conditions will prevail across the area under weak ridging occurring from the west-southwest. At the sfc, high pressure will become more centered across the western Atlantic well offshore, while weak low pressure and nearly stationary front remain across the Mid-Atlantic states.
High pressure over the area will move east out into the western Atlantic Ocean over the next few days with a southerly flow setting up bringing a gradual increase in temperatures and low level moisture.
A strong low pressure system will impact the area this weekend, with strong, heavy thunderstorms possible.
The stationary boundary/weak warm front that has been stretched across our CWA remains in place as we head into the overnight hours. Consequently, we end up eating the temperature gradient with our overnight low temperatures, with lows in the low/mid 30s along and north of I-70 and low in the upper 40s closer to the Ohio River. High temperatures on Thursday rise into the low 70s. As the disturbance moves off the the east, this finally dislodges the stationary boundary that has been hanging out over the area and it begins to lift north as a warm front ahead of the weekend system.
234 PM MDT Wed Mar 12 2025 KEY MESSAGES: 1) Warmer temperatures will persist into Thursday, with highs across northeast Montana reaching the 50s and 60s for most places.
Temperatures along the Island Chain are in the lower to mid 70s with a few isolated locations in the upper 70s. The high will continue to slowly slide into the western North Atlantic moving farther out towards the central North Atlantic by the weekend.
Precipitation will continue tonight in the wake of the front as an upper trough moves into the area with snow concerns expected around the Mount Shasta Area, and portions of the Eastside with moderate to strong winds in the Shasta Valley, and higher elevations east of the Cascades. Despite VFR ceilings into this afternoon, the higher terrain could end up partly obscured after 21z. A cold front will move inland this morning, with winds shifting from south to southwest and gradually diminishing.
- Warmer temperatures into Thursday with increasing south winds.
733 PM EDT Wed Mar 12 2025 - Mainly warmer than normal temperatures are expected into the weekend.
657 PM CDT Wed Mar 12 2025 - There is a 20 to 50 percent chance of light freezing rain north of Highway 2 tonight through early Thursday morning.
LAL and PGD have the highest chances for intermittent periods of IFR/LIFR conditions, especially closer to sunrise. High pressure over the area will move east out into the western Atlantic Ocean over the next few days with a southerly flow setting up bringing a gradual increase in temperatures and low level moisture.
5" right now and limited time before the wave reaches the lower Mississippi River Valley means not enough time for much moisture to move in from the Gulf of America.
The proximity of the high, along with earlier day time heating, has resulted in rather light winds ranging from northeasterly to southeasterly across the area. As the high pulls away and the effects of day time heating dissipate, surface winds will firm up slightly out of the east to east southeast. High pressure across the Florida Peninsula and northern Bahamas will push further out to sea through the night.
High temperatures on Thursday rise into the low 70s. As the disturbance moves off the the east, this finally dislodges the stationary boundary that has been hanging out over the area and it begins to lift north as a warm front ahead of the weekend system.
453 PM PDT Wed Mar 12 2025 An active weather pattern continue today with periods of rain, strong wind, thunderstorm chances, and some snow to the higher regional mountains. This is when we are expected to see minor urban and small stream flooding and when we are expecting to see the strongest winds with gusts up to 55 mph, up 70 mph in the higher terrain and typically windier spots. In addition, snow will be likely across the higher elevations as snow levels drop to between 2,200 to 3,000 feet across the North Bay and down to about 3,000 feet across the Central Coast overnight. The highest peaks in the Santa Lucia range can expect up to 12 inches of snowfall with light accumulations around Mt.
LAL and PGD have the highest chances for intermittent periods of IFR/LIFR conditions, especially closer to sunrise.
640 PM CDT Wed Mar 12 2025 (Tonight through Thursday night) Key Messages: - Elevated Fire Weather expected today and tomorrow (see Fire Weather Discussion) - A Weak and Dry Cold Front this Afternoon/Evening A weak and dry cold front associated with a mid-level trough over the Southern Plains is expected to move across our CWA from west to east before stalling across the Coastal Plains starting this afternoon into tonight. Slightly cooler conditions are in store behind the front. Thursday afternoon will warm to the low to mid 90s across much of the region in response to more efficient radiational heating due to the drier air and mainly clear skies. Thursday night lows will range in the low to mid 60s across the region.
At 8 PM MDT a cold front was in OR just west of Burns and should move slowly eastward through the night, and into western ID Thursday morning. Later Thursday graupel showers are expected in the colder unstable air mass behind the cold front.
(Today and tonight) Weak upper level ridging will result in above normal temperatures today. The next potent upper level low will approach West Central Texas from the west tonight into Friday.
- Much cooler over the weekend in the wake of the strong winds, with highs in the 50s and 60s. As the western trough approaches the central plains during the day Thursday, strong lee cyclogenesis will take place extending from eastern MT southward through eastern CO and northeastern NM. Daytime Friday, conditions across southwest KS will continue to deteriorate as the strong, negatively-tilted upper trough ejects onto the central plains.
High pressure remains in place over the Florida Keys today. Temperatures across the Keys before sunrise rose from the 60s into the 70s, the lowest being a measurement of 60 F at the Big Pine Key RAWS, into the low 70s once easterly winds interrupted radiational cooling. Dew points rose into the low 60s before sunrise as well.
1259 AM EDT Thu Mar 13 2025 - Mainly warmer than normal temperatures are expected into the weekend.
159 AM EDT Thu Mar 13 2025 - Mainly warmer than normal temperatures are expected into the weekend.
Areas west of I-55 will see nighttime temperatures in the low 60s. Elsewhere, areas along and south of I-20 will see highs in the low 80s.
Recent trends have the low a bit further south as it moves through our area. As far as the thunderstorm threat goes, the bulk of the moisture is still expected to remain to our north and east, but some recent model runs have some mid-level instability and saturation occurring Friday late afternoon across northeast Kansas before the low pushes out of the area.
1043 PM MDT Wed Mar 12 2025 - Mild and dry through Thursday - Elevated to critical fire weather conditions Thursday afternoon/early evening - Deep low pressure brings strong northwest winds Friday with some light rain/snow 19z surface analysis had trough from weak low over central MT to central NE. Water vapour loop had upper trough ready to invade the western CONUS with modest ridging over the CWA. Main forecast concern is fire weather Thursday and upper trough Friday. Tonight/Thursday, upper trough moves into the Rockies.
1209 AM CDT Thu Mar 13 2025 (Tonight through Thursday night) Key Messages: - Elevated Fire Weather expected today and tomorrow (see Fire Weather Discussion) - A Weak and Dry Cold Front this Afternoon/Evening A weak and dry cold front associated with a mid-level trough over the Southern Plains is expected to move across our CWA from west to east before stalling across the Coastal Plains starting this afternoon into tonight. Slightly cooler conditions are in store behind the front. Thursday afternoon will warm to the low to mid 90s across much of the region in response to more efficient radiational heating due to the drier air and mainly clear skies. Thursday night lows will range in the low to mid 60s across the region.
Weak high pressure will remain over the W Atlantic, FL Peninsula and E Gulf Basin today through Fri with low level flow becoming southerly which will bring slightly higher dew point airmass to the state with max temps climbing into the mid to upper 80s.
646 AM CDT Thu Mar 13 2025 - There is a 20 to 40 percent chance of light rain, snow, and freezing rain in northeastern North Dakota this morning.
640 AM CDT Thu Mar 13 2025 - Patchy freezing drizzle, light freezing rain, and light snow are possible this morning along and just south of the International Border, especially the northern Red River Valley. - Winter impacts are expected this weekend as a strong storm system brings freezing rain, heavy snow, and blowing snow into the region. Still looking at a dusting of snow in some areas, with pockets of light freezing rain. Zonal H5 flow this morning will give way to weak ridging later this afternoon, followed by an approaching upper low heading into Friday. This will bring our next chance for significant moisture into the area in the form of rain, freezing rain, and snow. As the upper low approaches the area late Friday, rain and isolated thunderstorms are expected across much of the region.
447 AM CDT Thu Mar 13 2025 Through Tonight: An upper-level low pressure system sliding east along the Interstate 40 corridor overnight has been instigating an area of thunderstorms under its colder mid-level temps (across central/eastern AR into far northern MS), but upper-level cold front feature was not enough to sustain showery development in our forecast area beyond midnight. Surface flow will remain out of the south as the broader synoptic low over the High Plains takes shape.
429 AM CDT Thu Mar 13 2025 - There is a 20 to 40 percent chance of light rain and freezing rain north of Highway 2 this morning.
- Well above average temperatures through Friday; slightly cooler this weekend behind a weak and dry cold front. Afternoon high temperatures will reach the low to mid 80s in most locations.
