Today: High pressure will continue sliding east through the day which will begin to shift the winds around to the south and east. The high clouds, 850mb temps still around -8C and snowpack will all act to keep high temps below freezing however most areas will climb into the lower to middle 20s. The one exception is across far southeast Kansas and the Highway 54 corridor where enough forcing could cause a few flurries late this afternoon and evening. Saturday: West to west northwest flow aloft will finally advect some warmer 850mb temps into the area (-2 to 2C). With the sunny skies, temps should finally break freezing, however did temper highs down into the middle 30s for most areas given the existing snow depth.
934 PM MST Thu Feb 20 2025 - Much warmer temperatures heading through the weekend. Water vapor shows upper trof axis from the Upper Midwest through the Central Rockies, with upper ridge over the Northern Rockies. At the surface, ridge is over the far eastern Dakotas, with staunch pressure falls westward to the Rocky Mountain Front. Much warmer temperatures can be expected through the weekend with generally flat upper ridge building overhead and Arctic air continuing to shallow/erode.

A low pressure center parked over the Colorado Springs area is pushing an easterly wave back across the mountains this morning. High pressure begins to build back over The West and clear skies, subsidence, and light winds should add up to a rather mild day on Saturday. A weak mid-level short wave trough in northwest flow moves over the forecast area Saturday night.
Thankfully, as the ridge begins to center overhead, winds are expected to greatly diminish by this afternoon. Under full sunshine filtered by high cirrus within the westerly flow aloft, highs will be able to range from the lower 40s in Marion County to near 50 degrees in Barbour County.
Clear skies and strong cold advection tonight has dropped temperatures in the low to mid 20s in many locations. The Arctic high pressure system will continue to move east through the Mississippi and Tennessee Valleys today with cold northeast winds persisting over the southeast, and temperatures will only be able to warm up into the mid to upper 40s, which is still about 12 to 16 degrees below normal. Still, winds will decouple as the center of high pressure passes into central NC, and lows will tumble again into the low to mid 20s. Despite sunny skies, highs are only expected to get into the low to mid 50s across the forecast area.
A dry weather system will pass through the Four Corners region today, resulting in breezy to locally windy conditions across the Lower Colorado River Valley.
Today looks to remain largely uneventful other than increasing clouds, as the weak upper ridge flattens, allowing a weak front to approach the Oregon coast late tonight into Saturday.
(Today and tonight) Expect another cold day across the area with temperatures a few degrees warmer, upper 30s to mid 40s. Tonight may a little more interesting across the far southeast counties as increasing low level moisture is overrunning a remaining cold airmass(surface temperatures below freezing). Expect no significant impacts, but a few slick spots are possible on bridges and overpasses so motorists should be prepared to slow down.
Current upper air models show ridge over the PAC NW, with northwest flow over the northern plains. Upper ridge builds over the Rockies and into the northern plains over the weekend, bringing much warmer temperatures compared to earlier this week.

Finally, elevated seas along the Lower Texas Coast will ensure a High Risk of rip currents at the local beaches throughout the entire short term forecast period.
622 AM EST Fri Feb 21 2025 Dry and cold weather will continue into the weekend as Canadian high pressure builds in from the west. Chilly temps will start the day with a Cold Weather Advisory in effect for wind chill values in the lower teens. Temps will reach above freezing by mid to late morning and will rise into the low to mid 40s, remaining well below normal. Gusty northwesterly winds will diminish through the day as gradient relaxes as low pressure moves farther off into the Atlantic and high pressure sprawls across the Southeast. Therefore temps will fall off quickly after sunset and will drop down to the low to mid 20s again. High pressure will move overhead Saturday and then offshore Saturday night. A coastal trough with possibly some low pressure along it will form offshore.

Midday satellite imagery shows a transitory ridge of high pressure building in from the west which is leading to continued mostly dry and quiet conditions across SE Idaho under a mix of mostly cloudy to mostly clear skies. Light flurries will be possible out of these low clouds at times which coupled with areas of freezing fog, may lead to slick travel conditions at times. Highs both today and Saturday will be in the 30s/40s with overnight lows below freezing in the teens/20s for most with coldest mountain basins dropping down into the single digits above and below zero.
A modest upper low over southwest Kansas spread several inches of snow over a small area of northwest Kansas this morning with radar imagery showing small areas of increasing returns in central Kansas. Could see enough shower activity in the frontogenetical/deformation area of this low produce some light snow to the ground mainly along and south of I-70 over the next several hours before the low departs into southwest Missouri.
