554 AM EST Wed Feb 24 2021 Aviation - Windy today - Colder Temps for Thursday - Above normal Temps for the weekend - Windy today A wave of low pressure will track eastward across Northern Michigan today. The low level winds will veer to the north later today and into tonight.
Expect gusty southwest winds today, with cooler conditions on Thursday. A second disturbance later this weekend provides another round of windy and cooler weather, along with another chance of light showers. The long-wave pattern of an eastern Pacific ridge and a broad trough over the continental United States will remain intact through much of this forecast period. Arizona lies on the eastern side of the ridge, only receiving fleeting/glancing blows from any s/wvs that do make it over.
639 AM EST Wed Feb 24 2021 High pressure will remain over the area today then move offshore and away from the region tonight as a weak cold front approaches from the north.
A cold front moved across the CWA last evening. Models have some weak upward vertical velocity over the CWA today and tonight as an upper trough moves into western Colorado by 12Z Thursday morning. The low level winds have an upslope component to them through today and much of tonight.
946 AM EST Wed Feb 24 2021 A cold front will move through the Ohio Valley today bringing a chance for showers.
312 AM CST Wed Feb 24 2021 A weak cold front is currently moving through the region early this morning.
423 AM MST Wed Feb 24 2021 Current surface analysis shows cold front east of the region, with high pressure over the intermountain west.
A weak cold front is currently located in the Texas Panhandle and northwestern Oklahoma and will continue to push south through the morning hours. Lows tonight will be cooler, in the 40s in the Hill Country and in the 50s across much of the remainder of the area. Weak overrunning conditions will continue and encompass much of the area with areas east of the I-35 corridor having the higher probability for the light shower activity. Highs tomorrow will be in the middle 50s to near 70 degrees with the cooler values in the Hill Country and Edwards Plateau.
Will see temperatures drop back down to freezing or below across all but our southeast, and could feel a little bit cooler with the wind chill.
In the wake of the cold front, today's temperatures will be cooler and closer to normal for this time of year: Expect highs in the mid 30s to low 40s.
It looks like there is some ice on the Kulm NDDOT webcam, with previous forecasts noting the chance for some light freezing rain this morning, so continued this chance for the next few hours. Forecast soundings indicate a lack of ice aloft briefly, therefore, some light freezing rain may mix in before the column fully saturates and produces light snow. A weak ridge and zonal flow will lead to warmer temperatures Thursday. A series of weak cold fronts will push through toward the weekend.
The upper westerly flow moving over the Rockies and central High Plains sags south and begins to turn more southwesterly as a short wave trough drops through the Intermountain region today and moves into the 4-corners area as an open wave by mid-day Thursday. The cooler area of high pressure that moved into the High Plains behind a cold front last evening will continue to expand across the plains today and tonight.
A cold front will approach and move through the region from northwest to southeast during the day today.
A quick moving upper level trough will trek across the northern tiers of the US today and a cold front associated with this trough will push down through the region this morning, hindering high temps this afternoon. The cold air will continue pushing southward and Thursday will be the coldest day of the week with highs in the low 40s and 50s and warmer temperatures along the Rio Grande. A trough swinging down from the Pacific NW will hit the four corners by Thursday morning, making its way to Texas by Thursday afternoon. Models indicate some convection as this trough moves through, although the greatest chance for precipitation remains to the east of our area.
Building high pressure will keep the region dry during the late week. Despite a period of strong ascent over the ridges due to frontogenesis, problems with showers and combined snow melt will be limited due to the systems quick exit. Shortly before midnight the cold front will finally reach our area, any remnants of low level moisture may create a snow/rain mix in ridges of West Virginia. Warm advection via wsw flow on the van of a Wrn CONUS trough is likely to maintain seasonable warm temperature into the weekend.
535 AM EST Wed Feb 24 2021 Dry high pressure will dominate today into Thu. A sfc cold front will lose much of it's moisture as it reaches the ILM CWA midday Thu and tries to further drop across the FA by sunset Thu. Forcing avbl along the cold front but just not enough moisture avbl for pcpn occurrence. The AC/SC may limit max temps Thu, especially closer to the cold front, ie. Clouds increase Thursday night, with lows in the low-to-mid 40s.
318 AM MST Wed Feb 24 2021 Slow moving cold frontal boundary, which pushed south through the I- 80 corridor, has began to pick up speed as it continues to dig to the south/southeast. In the wake of the frontal boundary, wind is expected to remain much lighter than seen over the past few days, as the low-level gradients lessen significantly. The passing of this front has brought temperatures down significantly to more seasonable conditions, with highs in the low 30s east of the Laramie range, and in the mid to low 20s to the west. However, it does look that snow will remain under half an inch for the plains and upwards to an inch for the higher peaks, due to limited upper level support and weak upslope flow.
501 AM CST Wed Feb 24 2021 A weak cold front is currently moving through the region early this morning.
420 AM CST Wed Feb 24 2021 A cold front will approach and move through the region from northwest to southeast during the day today.
VFR will return this afternoon with north winds as a weak cold front moves into the area. A weak cold front is currently located in the Texas Panhandle and northwestern Oklahoma and will continue to push south through the morning hours. Lows tonight will be cooler, in the 40s in the Hill Country and in the 50s across much of the remainder of the area. Weak overrunning conditions will continue and encompass much of the area with areas east of the I-35 corridor having the higher probability for the light shower activity. Highs tomorrow will be in the middle 50s to near 70 degrees with the cooler values in the Hill Country and Edwards Plateau.
/issued 332 AM CST Wed Feb 24 2021/ Weakly cyclonic westerly flow aloft today will back southwesterly tonight in advance of an upper level low pressure trough approaching from the west. At the surface, a cold front that swept through the area early this morning will be south of the area by daybreak.
Mid-level ridging across the Yucatan peninsula and NW Caribbean will keep zonal flow aloft across the region. Models would also suggest a weak trough pushing southward across the coverage warning area late tonight as winds begin to become NWRLY after midnight and towards sunrise. Weak high pressure over the area with light pressure gradient in place.
Northwesterly flow aloft ahead of a deepening trough is in place this morning, centered over the ID/MT/WY region and breezy northwesterly flow locally at the surface. Highs today will be much cooler than yesterday but as temperatures climb to around 40, we will see continued reduction of snowpack.
A cold front will bring a northerly wind shift to all TAF sites over the next 3 hours. A quick moving upper level trough will trek across the northern tiers of the US today and a cold front associated with this trough will push down through the region this morning, hindering high temps this afternoon. The cold air will continue pushing southward and Thursday will be the coldest day of the week with highs in the low 40s and 50s and warmer temperatures along the Rio Grande. A trough swinging down from the Pacific NW will hit the four corners by Thursday morning, making its way to Texas by Thursday afternoon. Models indicate some convection as this trough moves through, although the greatest chance for precipitation remains to the east of our area.
310 AM CST Wed Feb 24 2021 A cold front continues to push through the forecast area this morning and will effectively end our short run on 60 degree temperatures.
305 AM MST Wed Feb 24 2021 Current surface analysis shows cold front east of the region, with high pressure over the intermountain west.
320 AM CST Wed Feb 24 2021 Cold front has pushed into portions of northeast Oklahoma early this morning, currently located near a Pawnee, Nowata line. Very mild conditions ahead of front with temperatures currently running in the lower 60s.
328 AM CST Wed Feb 24 2021 A cold front will approach and move through the region from northwest to southeast during the day today.
711 AM EST Wed Feb 24 2021 High pressure will slowly move offshore later today and tonight. A weak cold front will cross the area on Thursday. Low pressure will impact the Southeast Coast into the weekend with unsettled weather. With high pressure sliding offshore, W/SW winds increase this afternoon and that will help push the high temperatures into the lower 70s in many areas away from the water, with mid to upper 60s along the coast, except closer to 60 degrees on the northern Outer Banks. Winds will be SW but will start to veer to NW just before daybreak as a dry cold front crosses the area and moves offshore during the early morning hours. A dry cold front will push through early Thursday morning with high pressure building in briefly.
High pressure ridging will continue to bring clear skies and slightly above average temperatures today, with high temps this afternoon reaching into the upper 70s and lower 80s. High pressure axis will be south of the forecast area through tonight and into Thursday morning with overnight low temperatures ranging between the mid and upper 40s.
1141 AM CST Wed Feb 24 2021 A cold front continues to push through the forecast area this morning and will effectively end our short run on 60 degree temperatures.
Visible satellite imagery highlights cumulus clouds streaming northward off the traditionally-favored islands in the Lower Keys.
1252 PM EST Wed Feb 24 2021 A cold front will move through the Ohio Valley today bringing a chance for showers.
Despite the abundant cloud cover, temperatures should have no trouble climbing into the lower 70s, though did shave a bit off of the previous forecast. The cold front will move into the forecast area later tonight, then stall across the forecast area as flow aloft becomes more zonal. South of the front, with warm and moist south winds moving over the cooler near shore waters, some patchy sea fog will be possible, however this looks to be mainly near the coast, as lift and winds seem to favor more low cloudiness further inland.
1030 AM EST Wed Feb 24 2021 High pressure will remain over the area today then move offshore and away from the region tonight as a weak cold front approaches from the north.
Brief rain showers are expected as a cold front pushes through the Commonwealth through this evening.
1045 AM MST Wed Feb 24 2021 Slow moving cold frontal boundary, which pushed south through the I- 80 corridor, has began to pick up speed as it continues to dig to the south/southeast. In the wake of the frontal boundary, wind is expected to remain much lighter than seen over the past few days, as the low-level gradients lessen significantly. The passing of this front has brought temperatures down significantly to more seasonable conditions, with highs in the low 30s east of the Laramie range, and in the mid to low 20s to the west. However, it does look that snow will remain under half an inch for the plains and upwards to an inch for the higher peaks, due to limited upper level support and weak upslope flow.
234 PM CST Wed Feb 24 2021 Following passage of a cold front this morning, our temperatures this afternoon have dipped back down to near average for this time of year with temperatures currently in the mid 50s to mid 60s across the region. Lows tonight be cool tonight as many locations will drop below freezing by tomorrow morning under clear skies. Scattered showers will also spread into northeast Oklahoma and northwest Arkansas late Thursday night, and temperature profiles may be cold enough for a mix of snow and rain to develop, especially across some of the higher elevations of northwest Arkansas.
Winds calm as the high moves in and become light and variable lasting through the day Thursday. The high also ushers in cooler air limiting Thursday's highs to the mid-40s.
1133 AM CST Wed Feb 24 2021 A weak cold front is currently moving through the region early this morning.
Lead cold front stretches southwest down through Ohio. Weak wave of low pressure will follow, sliding through the northern lakes region on Thursday. Meanwhile, as mentioned, secondary weak low level wave of low pressure slides across the northern lakes region on Thursday.
Decent low level WAA will be able to bring us back into the lower 40s in western MN & IA and upper 40s in south- central SD, largely in part to the winds gusting 20-25 mph. As the surface pressure gradient remains tightened across the area, expect windy conditions to continue into the late afternoon hours before decreasing after the associated cold front moves through.
In general for Western Montana, snow totals will be relatively low with the highest amounts likely along I-90 and to the south.
A weak area of high pressure centered in the vicinity of the Florida Panhandle will push eastward into western Atlantic on Thursday.
241 PM CST Wed Feb 24 2021 Temperatures today are noticeably cooler than yesterday for all but far southern zones, as a cold front continues to slowly sag southward across the region. Cold advection in the wake of the front will make for a colder night tonight, especially across portions of Lea county and the northern Permian Basin, where lows will dip below freezing, with lows in the mid 30s and 40s expected for most of the remainder of the area. The best chance for precipitation will be across the eastern Permian Basin, Lower Trans Pecos, and Stockton Plateau, and given precipitation looks to come to an end before temperatures have a chance to fall below freezing late Thursday night, only light rain is expected.
1015 AM PST Wed Feb 24 2021 Today will be sunny and mild with high pressure building over the Great Basin.
Cold front is currently pushing through southeast OK and will clear the forecast area by early afternoon.
Upper low continues to sag south through the forecast area this morning.
At the surface, weak high pressure resides across much of the area, with low pressure well to the north.
1011 AM EST Wed Feb 24 2021 Dry high pressure will dominate today into Thu. A sfc cold front will lose much of it's moisture as it reaches the ILM CWA midday Thu and tries to further drop across the FA by sunset Thu. Forcing avbl along the cold front but just not enough moisture avbl for pcpn occurrence. The AC/SC may limit max temps Thu, especially closer to the cold front, ie. Clouds increase Thursday night, with lows in the low-to-mid 40s.
1137 AM CST Wed Feb 24 2021 (Today and tonight) A weak cold front will move across West Central Texas this morning. Slightly cooler temperatures are forecast today, with highs in the low to mid 60s across the Big Country and the upper 60s to mid 70s elsewhere.
1125 AM EST Wed Feb 24 2021 Dry high pressure will dominate today into Thu. A sfc cold front will lose much of it's moisture as it reaches the ILM CWA midday Thu and tries to further drop across the FA by sunset Thu. Forcing avbl along the cold front but just not enough moisture avbl for pcpn occurrence. The AC/SC may limit max temps Thu, especially closer to the cold front, ie. Clouds increase Thursday night, with lows in the low-to-mid 40s.

Current surface analysis shows cold front east of the region, with high pressure over the intermountain west.
A cold front will bring slightly cooler temperatures for the end of the week, compared to what central Indiana has seen in the past couple days.
315 PM EST Wed Feb 24 2021 Showers will end with passage of a cold front this eve. High pressure will keep the region until rain chance returns for the weekend. A brief transition to snow is possible over the ridges with frontal passage, but progression and lack of mixing depth will limit accumulation potential.
220 PM EST Wed Feb 24 2021 High pressure will bring another day of sunny skies and above normal temperatures to the region. A dry cold front will move through the area early Thursday, bringing slight cooler temperatures and a period of increased clouds to the area, but no rain.
With light winds, clear skies, and the cooler airmass settling into the region, low temperatures will be colder than the past few mornings with most locations near or below freezing. With cloudy skies and the cooler airmass still in place, daytime high temperatures will be about 10- 20 degrees colder than today with most locations struggling to climb out of the lower 40's. It should be just mild enough to secure liquid with any sprinkles/showers, likely diminishing before surface temperatures dip below freezing Thursday night.
240 PM EST Wed Feb 24 2021 High pressure over the area today will move offshore and away from the region tonight as a weak cold front approaches from the north.
Low temperatures this evening will be below freezing for much of the area.
1030 AM EST Wed Feb 24 2021 High pressure will slowly move offshore later today and tonight. A weak cold front will cross the area on Thursday. Low pressure will impact the Southeast Coast into the weekend with unsettled weather. With high pressure sliding offshore, W/SW winds increase this afternoon and that will help push the high temperatures into the lower 70s in many areas away from the water, with mid to upper 60s along the coast, except closer to 60 degrees on the northern Outer Banks. Winds will be SW but will start to veer to NW just before daybreak as a dry cold front crosses the area and moves offshore during the early morning hours. A dry cold front will push through early Thursday morning with high pressure building in briefly.
At 10 AM EST current readings are in the lower to mid 50s. Tonight, winds will decrease and clouds increase from the north ahead of an approaching cold front.
207 PM EST Wed Feb 24 2021 A zonal mid-level flow persists over the Florida peninsula with flat ridging extending through the southern Gulf of Mexico and over southern Florida. The surface reflection is a pair of high pressure centers located over the northeastern Gulf of Mexico and near Bermuda.
Forcing for ascent ahead of this trough will combine with upslope flow to foster light snow development mainly west of U.
120 PM EST Wed Feb 24 2021 High pressure over the area today will move offshore and away from the region tonight as a weak cold front approaches from the north.
Wind gusts up to 70 MPH expected near Arlington starting around 5 PM Thursday, so the High Wind Watch has been upgraded to a High Wind Warning. The I-80 Summit area and areas along I-25 up to Wheatland currently has a High Wind Watch out and due to uncertainty in the timing of when the high winds will kick in, it will stay a High Wind Watch for now.
1129 AM CST Wed Feb 24 2021 10am Update Temperatures were bumped down to account for cloud cover due to the weak cold front on approach. Wind gusts were bumped up out ahead of the cold front. RH values bumped down as the air mass ahead of the cold front is pretty dry. The low level jet has been cranking around 50 knots all night. Latest surface analysis places a 1003mb low over the Great Lakes with a cold front extending from Green Bay back through Saint Louis and into Oklahoma City.
1146 AM PST Wed Feb 24 2021 High pressure brings quieter weather to the Inland Northwest for Wednesday.
At 10 AM EST current readings are in the lower to mid 50s. Tonight, winds subside, and we see increasing cloud cover from the north ahead of an approaching cold front.
(This evening through Thursday) Sunny and a little cooler behind the cold front, with highs in the 60s and 70s. Cooler across Oklahoma and thats the air mass settling into West Central Texas tomorrow. Models are forecasting increasing low cloudiness by sunrise tomorrow morning as a warm and more moist air mass runs up and over this cooler mass settling into the area.
High pressure will keep the region dry during the late week. Warm and moist advection has occurred all morning so far, and may allow for lapse rates in the low levels to reach 6. With any lingering showers over the WV Ridges, a transition to snow may be possible with frontal passage. Once the cold front passes late tonight, much colder temperature will be observed area-wide. Seasonable temperature is expected Thursday, with building high pressure throughout the column. Expect cloud cover to be on the increase as a cold front approaches the region. VFR conditions will return on Thursday with building high pressure.
309 PM EST Wed Feb 24 2021 Warm sector in advance of approaching cold has remained relatively cloud free over much of the forecast area this morning into early afternoon with temperatures responding and climbing into the upper 40s to lower 50s along and south of I-69 with slightly cooler readings north where clouds have been more persistent. With gusty west to southwest winds and dew points into the lower to mid 30s, the slow/steady snow melt that began yesterday has continued.
238 PM CST Wed Feb 24 2021 After yet another pleasant day, northerly low-level flow will advect cooler air into region overnight.
High pressure building in on Thursday will provide dry weather through the end of the work week. tonight, dragging a cold front to the southeast of the CWA by midnight. Cool high pressure will build into the Ohio Valley on Thursday under rapid zonal flow.
1230 PM EST Wed Feb 24 2021 Aviation - Windy today - Colder Temps for Thursday - Above normal Temps for the weekend - Windy today A wave of low pressure will track eastward across Northern Michigan today. The low level winds will veer to the north later today and into tonight.
The clouds will clear again early Thursday with high pressure centered to the south.
At the surface, winds will shift more toward the southwest late tonight ahead of a weak cold front approaching the forecast area from the northwest. With the low level moisture continuing late tonight into Thursday morning, there is again a good signal for fog development in the models and conditions would suggest it to be a little more pronounced over southern and eastern portions of our forecast area during that time. Temperatures on Thursday will again be well above seasonal norms, with highs ranging in the low to mid 70s across the region.
Subtropical ridging over the Caribbean Sea will keep abnormally warm temperatures in place through Thursday night. A strong pressure gradient will remain in place as low pressure across northeast Mexico interacts will strong high pressure over the eastern Gulf of Mexico. A slow and nearly stationary, weak cold front will continue to push south from central Texas through the day on Thursday, stalling just north of the CWA by Thursday evening.
/Tonight through Wednesday/ Take Home Points: *Snow melt continues *Temperature roller coaster, with mostly above freezing highs *Periodic light precipitation chances Discussion: While it was a markedly cooler day across the state, it remained hard to complain too much about considering the bitter cold only a few days in our rear view mirror. That too will keep Thursday highs similar to today with little opportunity to advect in any appreciably warmer or colder air masses.
Meanwhile, s/w ridging will assert itself across the region on Thursday.
