/Tonight through Wednesday Night/ Dry and stable conditions to persist through the short-term period as the region remains under the influence of weak upper- level ridging aloft and firmly established high pressure at the surface. Without much airmass movement over the next 36 hours, diurnal temperatures swings will remain fairly persistent with low temperatures both tonight and tomorrow night around 40 degrees with highs on Wednesday in the lower to middle 70s.
Likely will be 1 to 3 degrees warmer in most locations, and have nudged temperatures closer to CONSMOS/90th percentile NBM values. Dewpoints are expected to be higher tomorrow, but have still kept them closer to the lowest guidance.
1243 PM EST Tue Mar 1 2022 A cold front sliding through southern Lower MI at press time moves south and east of the border by mid afternoon. Diffuse high pressure then settles overhead after midnight through sunrise with the resulting weak cloud layer wind allowing clouds to hang around through Wednesday morning. Temperatures will warm into the lower to mid 40s most areas with upper 30s holding on from northern Saginaw Valley into the Thumb.
Feel there is a decent chance lows will be colder than expected east of the Buffalo Ridge as high pressure tries to linger into the later evening, but an approaching jet max to the north of the area should help bring a small increase to winds overnight so temperatures should stabilize.
237 PM EST Tue Mar 1 2022 High pressure dominates our weather through late week.
Low pressure will transition east over the northern Great Lakes today with a trailing cold front progged to cross the region later this afternoon and through the evening, returning a chance of precipitation to the region. CAA with diurnal trends will allow temps to drop into the low 30s and even upper 20s overnight.
230 PM EST Tue Mar 1 2022 Mild weather continues through Wednesday before a cold front will bring a brief shot of colder weather.
202 PM CST Tue Mar 1 2022 It's a scortcher out there! Several places are already into the low 70s with all this sunshine and weak southwest flow.
349 PM EST Tue Mar 1 2022 High pressure dominates our weather through late week.
High pressure at the surface and a dry airmass aloft will persist during the forecast period.
Satellite imagery also shows the weak Rex block centered over western Utah is slowly marching east with the first strong low pressure system dropping south over the eastern Pacific behind it. This is in good agreement with the models which predict the ridge will be centered over Western Colorado late Wednesday.
The freezing drizzle potential looks even lower than it has over the past couple days as the moisture does look deep enough/cold enough to introduce ice crystals. The trough will slide southeast of the area Wednesday afternoon along with the favored jet support, which will allow the snow to diminish from west to east; however, the cloud cover will linger across the area. Wednesday Night Through Tuesday The most impactful weather in this part of the forecast will occur this weekend when a strong low pressure system tracks northeast across the area.
226 PM CST Tue Mar 1 2022 Temperatures today are still on track to top out in the lower 70s across much of the area with 1:30 PM observations on the West Texas Mesonet showing temperatures in the mid-60s. Winds tonight should remain relatively light as we are currently under an upper ridge. The upper ridge will amplify some tomorrow as an upper trough moves towards the area from the desert southwest. With the ridge somewhat amplifying, temperatures will be 1 or 2 degrees warmer tomorrow compared to today.
1059 AM MST Tue Mar 1 2022 Due to the shifting pressure gradient, the probability to see gusts above 58 mph in the foothills west of Billings has decreased, hence will cancel the wind advisory and let the high wind warning expire. Vertz Ridging over the area today and Wednesday will keep mainly dry conditions and warm temperatures in place. The impetus for the strong wind gusts diminishes this afternoon as the jet lifts north with the ridging weakening lee side pressure falls. A stronger jet streak crosses north of the area Wednesday and the right rear quad of the jet will help to pull a backdoor front in from the northeast during the day into Wednesday night as it crests the ridge and dives southeast into the plains.
225 PM EST Tue Mar 1 2022 Dry weather is expected through Wednesday with temperatures trending warmer.
Early afternoon satellite imagery continued to show a shallow ridge of high pressure across the NW states with ribbons of precipitation topping the ridge and traversing the CNTRL mountains and WRN Washington. Numerical models continue to show moisture skirting the region tonight but lifting further north into NRN Idaho Wednesday and Wednesday night as an elongated upstream Pacific trough advances into the NW coastal waters. The main feature of interest here is the warming spring-like temperatures spreading into the region ahead of the trough.
(Wednesday night through next Tuesday) Gradual warming trend to continue through the rest of the week as ridge aloft moves across the Southern Plains.

At the lower to mid levels, northwest flow will allow for dry and stable conditions. Afternoon high temperatures forecast to climb into the lower 70s areawide with relative humidity values falling to around 25 to 30 percent. A steady stream of upper level moisture and cirrus clouds are moving over the region in the flow aloft ahead of an upper level low over Southern California/North Baja. This low will cut off and weaken as it becomes trapped underneath a building upper ridge over the Western CONUS today and into Wednesday. As the upper ridge strengthens, this will transition the flow aloft to northwesterly and gradually bring in some drier air from the north.
The high pressure will begin to shift to the east tonight and Wednesday bringing east to southeasterly flow back to the area. Cloud cover will increase Wednesday night as a weak coastal trough develops.
110 PM EST Tue Mar 1 2022 Aviation - Clippers bring chance of light precip today and Wednesday The large scale pattern the next couple days features fast northwest flow between western CONUS ridging and an upper low over eastern Canada. A departing clipper trails a cold front through Lower Michigan today with light snow/rain possible across the southern zones this afternoon, in an area of low level convergence.
A large, upper trough will continue to depart to the east through the near term, with zonal flow taking hold aloft late Wednesday afternoon as an upper ridge builds over the western CONUS and begins to progress over the central CONUS. After a chilly night in the upper 30s to lower 40s tonight, highs Wednesday afternoon will then reach the lower to mid 70s.
1116 AM MST Tue Mar 1 2022 Aside from a few clouds across northwest Colorado, skies remain clear this morning thanks to the ridge of high pressure in place over the Four Corners region. A cutoff area of low pressure along the California/Arizona border has set up a Rex Block that will keep eastern Utah and western Colorado high and dry through the end of the work week.
Overnight lows are expected to be mainly in the lower 40s away from the coast, but a few inland pockets will reach the upper 30s.
Surface pressure falls today as weak high pressure loses its influence across the area. We continued with the warmer high temps and lower dew points approach (though values should be up a bit).
An upper low drifting east from southern AZ will spread mid to high level clouds across the southeast half of NM thru Wednesday morning.
Temps will be cool again tonight but warmer than prev mornings. Highs Wed will be warmer than today with mid 70s.
An unseasonably warm start to March is expected across the local area today as temperatures climb into the lower 70s across much of the region. While temperatures aloft are very similar to yesterday, with the warmer start to the day and full sunshine, think that we should top yesterdays highs by a few degrees. As the upper level ridge aloft pushes further east on Wednesday, expect temperatures to climb even further, with widespread readings in the mid 70s expected across south central Nebraska, along with a few 80s possible across north central Kansas.
Dry high pressure over the region will weaken through mid week and then move into the W Atlantic for the rest of the week and into the weekend with generally light winds and slight seas along with afternoon seabreeze development. Dry high pressure will remain in the region with low afternoon RHs but light winds and moderate ERC values are not expected to support red flag conditions.
327 PM EST Tue Mar 1 2022 A mostly dry northwest flow will persist through late this week, with some weak upper level disturbances and associated surface cold fronts pushing through our region late today and again late Wednesday.
233 PM CST Tue Mar 1 2022 High pressure continues to promote tranquil weather across the Tennessee Valley as clear, dry, and calm conditions are prevailing.
Made some minor upward adjustments to hourly temperatures with southwesterly flow starting to warm up the ridge tops. Low level southwesterly flow will see a modest uptick in strength with resultant wind gusts in the upper teens to lower 20s through this afternoon as gradients tighten in advance of a weak cold front slated to approach overnight. Although rather moisture starved, this cold front could yield some sprinkles across our northeastern counties for a few hours during the overnight hours. A warm and breezy day is expected Wednesday as a weak area of high pressure slides off the East Coast and interacts with a front sweeping through the Midwest and Great Lakes.
Tranquil weather across the Tennessee valley region today with high pressure firmly in control of the weather.
910 AM CST Tue Mar 1 2022 Tranquil weather across the Tennessee valley region today with high pressure firmly in control of the weather.
This fantastic weather will continue through the work week as dry, northwesterly flow aloft persists downstream of a broad, low- amplitude ridge over the Intermountain West.
244 PM EST Tue Mar 1 2022 High pressure along with drier air will build into the region through mid-week.
1220 PM EST Tue Mar 1 2022 Dry and warmer weather is on tap into Wednesday before a cold front brings a brief shot of colder weather and a small chance for some light rain or snow by Wednesday night. The clouds have helped temperatures remains fairly steady much of the night, but these same clouds (which continue well upstream into MN) could hamper full mixing of the warmer h85 temps that will be in place to start the day (but begin to lower across the north as the wave passes through. The warmer air will be nudged south briefly tonight with h85 temps back to 0 to +3 C, yielding lows in the 30s.
We'll stay chilly overnight tonight with good radiational cooling, but warmer than last night with above freezing temps expected.
1026 AM EST Tue Mar 1 2022 High pressure along with drier air will build into the region through mid-week.
A region of lower- middle tropospheric subsidence connected to this jet streak has shifted to our east, with an attendant surface anticyclone situated near the Louisiana-Texas border. Anticipate highs ranging from the low-mid 70s through the remainder of the afternoon, with a scattering of upper 60s possible from the southern Edwards Plateau through Hill Country. Given how small this layer is forecasted to be, any sort of wind at the surface would likely mix this layer out with the much warmer and drier layer residing immediately above it. Benefiting from decreasing clouds through the second half of the day, temperatures should climb into the low-mid 70s across the entire CWA - including our higher-elevation communities in the southern Edwards Plateau and Hill Country.
159 PM MST Tue Mar 1 2022 WNW flow aloft will remain over the area, tonight through Wednesda,y as a sfc lee trough becomes better organized.
Made some minor upward adjustments to hourly temperatures with southwesterly flow starting to warm up the ridge tops. Low level southwesterly flow will see a modest uptick in strength with resultant wind gusts in the upper teens to lower 20s through this afternoon as gradients tighten in advance of a weak cold front slated to approach overnight. Although rather moisture starved, this cold front could yield some sprinkles across our northeastern counties for a few hours during the overnight hours. Precipitation will be light, and mainly in the form of rain, although a few flakes cannot be ruled out across the higher terrain.
Snow levels will remain above valleys but the ground is still quite cold, with many locations still seeing sub-surface temperatures below freezing. So for the third straight morning, patchy freezing rain is possible, mainly along and north of I-90 but including shady stretches of road in west- central Montana.
At the upper levels, there is general troughing over the northeast and ridging over the western portion of the country, with NW flow aloft locally.
VFR conditions along with light, variable winds will prevail through the fcst period underneath high pressure.
It's a scorcher out there! Several places are already into the low 70s with all this sunshine and weak southwest flow.
Similar, though slightly warmer, weather is expected tomorrow, with high temperatures in the low to mid 70s. /NEW/ /Wednesday Night through Tuesday/ Mid level ridging will prevail across the Southern Plains into the upcoming weekend promoting a continued warming trend.
Surface analysis this evening places a ridge of high pressure over the Lower Mississippi Valley near the Gulf Coast. This fantastic weather will continue through the work week as dry, northwesterly flow aloft persists downstream of a broad, low- amplitude ridge over the Intermountain West.
603 PM MST Tue Mar 1 2022 Upper level ridge and plenty of cloud cover courtesy of a moist Pacific flow will yield another warm night in our region. Precipitation will form along a stalled front overnight, with soundings showing a warm nose and saturated atmosphere conducive to freezing rain potential.
354 PM CST Tue Mar 1 2022 The main highlight for the short term period is a Winter Weather Advisory for freezing rain that is in effect from 6 pm CST this evening until 9 am CST Wednesday morning. While some of this will fall as snow, a fair amount is also expected to fall as freezing rain. Freezing rain is supported by model soundings suggesting a loss of ice in the DGZ throughout much of this event. Therefore, the aforementioned Winter Weather Advisory for freezing rain was issued over a large swath of the forecast area from northwestern North Dakota down through the southern James River Valley.
/issued 223 PM CST Tue Mar 1 2022/ SHORT TERM (Tonight through Wednesday Night): High pressure continues to build across Deep South Texas, with very comfortable conditions expected both today and Wednesday. Highs should reach the low to mid 70s today and mid to potentially upper 70s tomorrow.

642 PM CST Tue Mar 1 2022 Current satellite imagery shows just some mid/high clouds moving over the High Plains with surface observations showing very warm readings this afternoon. Expect quiet and warm conditions will persist through tomorrow with lows tonight generally 30 to 35 and highs tomorrow ranging from around 70 along the NE/SD border to the low/mid 70s along and south of Interstate 80. Temperatures to the north will be feeling the effects of a cold front pushing down from the northeast.
/issued 226 PM CST Tue Mar 1 2022/ Temperatures today are still on track to top out in the lower 70s across much of the area with 1:30 PM observations on the West Texas Mesonet showing temperatures in the mid-60s. Winds tonight should remain relatively light as we are currently under an upper ridge. The upper ridge will amplify some tomorrow as an upper trough moves towards the area from the desert southwest. With the ridge somewhat amplifying, temperatures will be 1 or 2 degrees warmer tomorrow compared to today.
With an upper level ridge currently over much of the western CONUS and expected to be not much further east Wednesday, temperatures will again be unseasonably warm under mostly clear skies, with highs in the mid to upper 70s.
640 PM EST Tue Mar 1 2022 Forecast remains unchanged as high pressure continues to settle across the peninsula providing dry and cool overnight conditions. Dry high pressure over the region will weaken through mid week and then move into the W Atlantic for the rest of the week and into the weekend with generally light winds and slight seas along with afternoon seabreeze development. Dry high pressure will remain in the region with low afternoon RHs but light winds and moderate ERC values are not expected to support red flag conditions.
647 PM EST Tue Mar 1 2022 High pressure along with drier air will build into the region through mid-week.
713 PM EST Tue Mar 1 2022 Light precipitation will be possible this evening with the passage of a cold front. Light rain is expected to continue through midnight for portions of our region as a trough and its associated cold front advances from the north. Despite the presence of the cold front, early morning temperatures for Wednesday will still range a few degrees above the climatological average with the lingering clouds.
500 PM MST Tue Mar 1 2022 WNW flow aloft will remain over the area, tonight through Wednesday as a sfc lee trough becomes better organized.
658 PM EST Tue Mar 1 2022 Dry weather is expected through Wednesday with temperatures trending warmer.
Then a stronger high will move down out of Canada on Wednesday night which will push the cold front back through the entire CWA. Tomorrow's highs will be a few degrees warmer than today's as low level thermal profiles will be slightly warmer. Then Wednesday night lows will be about the same as tonight's as the cold front begins to move through the area.
Mostly dry weather will continue across the region through Wednesday as an upper ridge amplifies over the Intermountain NW. An upper trough will approach the Pac NW coast Wednesday night. This approaching trough will keep winds out of the east to south through Wednesday night.
The stationary front is expected to be nudged south starting tonight as surface Canadian high pressure presses south.
752 PM MST Tue Mar 1 2022 800PM UPDATE: Changes to the forecast focused around the GLAMP brining dense fog to the region along the line with the stalled out cold front from Opheim to Wolf Point to Circle to Glendive to Wibaux. The stationary front is expected to be nudged south starting tonight as surface Canadian high pressure presses south.
After a sunny and warmer day across the forecast area today with highs in the 60s, temperatures were slowly dropping into the 40s to lower 50s with skies still clear. A weak inverted trough at the surface shifts eastward slowly overnight. High pressure to the south and weak pressure gradient across the region will lead to light SWLY winds tonight.
355 PM MST Tue Mar 1 2022 Weak high pressure over the Intermountain West will slowly move eastward the next two days, bringing a flattened ridge axis over western and central Wyoming. Some moisture in the flow continues light snow showers to the northwest mountains today and tonight, with the showers diminishing after midnight as the ridge axis pushes moisture into SW Montana. With the ridge axis moving over the area on Wednesday, similar temperatures are expected with highs into the upper 50s and 60s.
/NEW/ /Through Wednesday Evening/ Large-scale ridging will dominate for the next few days, providing above-normal temperatures and overall quiet weather across the region. High clouds will hang around for much of Wednesday, but the presence of the ridge and modest insolation should still allow temperatures to climb into the 70s Wednesday afternoon. /Issued 323 PM CST Tue Mar 1 2022/ /Wednesday Night through Tuesday/ Mid level ridging will prevail across the Southern Plains into the upcoming weekend promoting a continued warming trend.
High pressure continues to promote tranquil weather across the Tennessee Valley as clear, dry, and calm conditions are prevailing.
846 PM EST Tue Mar 1 2022 High pressure along with drier air will build into the region through mid-week.
High pressure will bring dry conditions along with a warming trend through the middle of the week.
312 PM CST Tue Mar 1 2022 The region is currently situated between high pressure to the east and low pressure to the west, with a frontal boundary splayed across the central part of the CWA. This has resulted in a large temperature gradient across the area, with temperatures currently in the mid 20s across west central Minnesota and far northeastern South Dakota, and in the lower 60s across south central South Dakota. There continues to be some warm air aloft in place, so may see a mix of freezing precipitation and snow, but amounts will be minimal and likely not impactful. Wednesday looks to be fairly quiet, but cooler, across the area as the high to the north noses southward.
Precipitation will form along a stalled front overnight, with soundings showing a warm nose and saturated atmosphere conducive to freezing rain potential.
401 PM EST Tue Mar 1 2022 Light precipitation will be possible today and tonight with the passage of a cold front. Light rain is expected to continue through midnight for portions of our region as a trough and its associated cold front advances from the north.

401 PM CST Tue Mar 1 2022 Current satellite imagery shows just some mid/high clouds moving over the High Plains with surface observations showing very warm readings this afternoon. Expect quiet and warm conditions will persist through tomorrow with lows tonight generally 30 to 35 and highs tomorrow ranging from around 70 along the NE/SD border to the low/mid 70s along and south of Interstate 80. Temperatures to the north will be feeling the effects of a cold front pushing down from the northeast.
236 AM CST Wed Mar 2 2022 The short term starts off with a mid level ridge over the western CONUS.
1258 AM EST Wed Mar 2 2022 Dry weather is expected through Wednesday with temperatures trending warmer.
The drier air is proving tough for models to adjust to, and since the air is drier than models suggest, we have been able to squeeze out some warmer high temps in the afternoon.
Observed 03z temps were a little warmer than fcst 03z temps across these less protected areas to our west and north and much colder across the more sheltered areas to our northeast and east.
1053 PM CST Tue Mar 1 2022 (Today and tonight) The very warm late winter trend continues today with general upper- level ridging to the west of Oklahoma.
