97 Lingering light snow will exit to the southeast this morning before high pressure settles across the region, bringing dry weather conditions this afternoon. Look for milder and drier weather conditions for Thanksgiving and extending into the upcoming weekend with upper ridging across the area.
1202 PM EST Wed Nov 24 2021 Southerly flow will support a dry and seasonable afternoon, but a cold front with rain can be expected on Thanksgiving. The filtered insolation is in response to increasing upper moisture flowing from Plains trough into the broad ern CONUS ridge. That ridge will maintain dry weather through tonight, with warm advection supporting a temperature recovery to near the seasonal averages. The cold front associated with that low is progged for evening passage across the Upr OH, with rain spreading across the region as it advance across the midwest on Thursday.
347 PM EST Wed Nov 24 2021 Dry weather will prevail overnight into most of Thanksgiving, as high pressure moves just to the east of the region early Thursday. A cold front will bring some rain showers into western PA Thursday afternoon and evening, with showers overspreading the rest of PA Thursday night.
A cold front is currently situated over central Kansas and is currently pushing through our northwestern counties. Thanksgiving Day will be much colder with highs in the low to mid 40s throughout the region.
1025 AM EST Wed Nov 24 2021 Water vapor imagery highlights the sinking air across the region associated with high pressure centered over the Appalachians. Winds are still elevated this morning due to the enhanced gradient due to high pressure continuing to build across the area. A windy, cooler morning is ongoing across the island chain, with temperatures still just below or near 70 degrees.
Plenty of sun will be around on Thanksgiving day with daytime temperatures running closer to normal (so a bit cooler than recent days). High pressure keeps us dry through Thursday night with another cold night expected Thursday night.
1220 PM EST Wed Nov 24 2021 High pressure will remain over the area through tonight. The high will shift south on Thursday as a cold front approaches from the west.
Thanksgiving morning may see a mix of rain and snow for some spots, before warmer temperatures drive snow levels up into the weekend. The one area where there is some fog is along the Highway 2 corridor west of Spokane through Davenport and to Wilbur. A warm front will overtop a ridge of high pressure that is situated over the Pacific Northwest tonight. There is a small chance for light freezing rain by Thanksgiving morning for colder pockets in the northern mountain valleys such as in the Methow Valley, Omak, Republic, and at the Colville Airport.
Widespread rain will move through the area late this evening into early Thursday with a cold frontal passage, but excessive rainfall is not expected. Short term conditions will be driven by the passage of a trough and cold front currently NW of the area. Precipitation: Rain will develop over the NW CWA this evening as the cold front and upper trough move into the area, then moves SE through the area through sunrise Thanksgiving morning. Thursday night - Cold: Incoming high pressure, clear skies, and light winds will lead to a very chilly night Thursday night.
High pressure over the Carolinas this afternoon, will weaken as it sinks south over the area Tonight. A cold front will approach the region from the northwest Thursday night, with clouds increasing.
235 PM EST Wed Nov 24 2021 High pressure over the coastal plain today will shift south on Thursday as a cold front approaches from the west.
Another dry day is on tap, with slightly warmer conditions than yesterday. In addition, upper ridging will remain in place through much of today before sliding east later this afternoon into this evening. Along with this, a cold front will approach from the northwest. /28/ On Thursday, a midlevel trough will make its way into the Lower Mississippi River Valley, which will offer some relief to the mostly dry conditions we have been experiencing. A line of non-severe storms accompanied with a cold front will make its way through our region early Thursday morning and propagate SE throughout the day into the evening.
As a cold front moves through tonight, cigs will lower with MVFR likely and IFR or worse possible. Today Through Thursday Night Temps are several deg warmer early this Wed morning compared to Tue morning due to the increased winds seen for most areas. a cold front to the NW of AR will move towards AR. The drier and cooler air will move into the state by Thu night behind the departing cold front.
Low pressure currently over western Wisconsin will move northeast tonight and drag a cold front through the state Thursday morning.
Thanksgiving morning may see a mix of rain and snow for some spots, before warmer temperatures drive snow levels up into the weekend. The one area where there is some fog is along the Highway 2 corridor west of Spokane through Davenport and to Wilbur.
200 PM EST Wed Nov 24 2021 High pressure will remain over the area through tonight. The high will shift south on Thursday as a cold front approaches from the west.

Strong low level jet along with tight pressure gradient in advance of a cold front continue to induce strong and gusty south winds this morning, with consistent gusts over 40 an several Mesonet sites and also noted in the high terrain of SE OK and western AR.
1256 PM EST Wed Nov 24 2021 Aviation - Becoming fairly windy later today - Southerly winds will gradually ramp up today as a result of a strengthening pressure gradient between the high pressure ridge over the southeastern CONUS and the low pressure system over the upper midwest. A consensus of latest high res short term guidance suggests the highest gusts will occur from near KMKG northward along the coast where some gusts to around 40 mph are possible. - Rain to light lake effect snow showers for Thanksgiving - The approaching cold front will bring rain showers late Wednesday night through midday Thursday.
345 PM EST Wed Nov 24 2021 High pressure will prevail across the region through Thanksgiving Day.
1141 AM CST Wed Nov 24 2021 Current observations show the cold front has pushed through all of north central Nebraska. Behind this front, cooler air is pushing into the central Plains. The coolest temperatures will be across the Pine Ridge region where cool 850 mb temperatures (-1C to -5C) will have the greatest impact on surface temperatures. Besides this nuisance light snow/flurries, the quiet weather pattern will continue through Thursday as upper level ridging builds back across the western US.
225 PM CST Wed Nov 24 2021 Windy conditions ahead of the upper trough and cold front that will bring rain to the mid state during the day tomorrow.
616 PM EST Wed Nov 24 2021 High pressure will prevail across the region through Thanksgiving Day.
Then, prob30 for MVFR at all sites late tomorrow afternoon as showers begin to move in ahead of a cold front. Precipitation chances begin to increase Thanksgiving afternoon and into the evening due to an approaching cold front. Discussion: The short term period begins with an upper level ridge axis transitioning across the Appalachian region, with a deepening trough upstream over the Great Plains and approaching the Midwest. With the presence of the cloud coverage tonight, overnight lows will be a few degrees warmer relative to previous days amidst the warm air advection brought on by south/southwesterly flow today. Heading into Thanksgiving, the southerly flow at the surface will continue to prevail ahead of the cold front, along with increasing sky coverage as model guidance shows some weak divergence aloft.
835 PM EST Wed Nov 24 2021 High pressure centered over the SE US will shift south and east of the area on Thursday as a cold front approaches from the west.
After a warm start to the morning, temperatures continue to fall this afternoon as a cold front passes through the Upper Midwest. Temperatures will take on a warming trend towards more seasonable values through the weekend, as the lower heights and cold air aloft moves eastwards over the Great Lakes.
602 PM CST Wed Nov 24 2021 (This evening through Thursday) A cold front will push into the area late tonight, and may result in some scattered showers across our southeast counties. A 1035mb high pressure center will push a cooler Canadian airmass into west Texas for Turkey Day, which should result in high temperatures in the mid to upper 50s. The aforementioned breezy conditions will continue through at least early afternoon, which will make the air feel a bit cooler than the actual temperature.
917 PM EST Wed Nov 24 2021 High pressure will prevail across the region through Thanksgiving Day.
549 PM CST Wed Nov 24 2021 Light rain will develop and blossom this evening in the vicinity of a cold front. Conditions will turn colder but remain blustery into Thursday as a modified Canadian air mass filters into the region behind the departing cold front. Light rain will develop as early as 00z/6pm this evening west of the Illinois River Valley ahead of the cold front and within a wing of warm advection. 40", with the higher amounts coming east of Interstate 55 overnight.
517 PM CST Wed Nov 24 2021 Key Points: * Cold front moving through the region this afternoon will be the trigger for sprinkles/light rain late this afternoon/evening.
Early afternoon analysis showed a surface cold front extending from the UP of Michigan southwestward through Iowa and into Kansas. Behind the front, northwest winds were generally gusting in the 25 to 35 kt range across the region, ushering in much cooler air for tonight and Thanksgiving.
700 PM EST Wed Nov 24 2021 High pressure over the coastal plain today will shift south on Thursday as a cold front approaches from the west.
528 PM CST Wed Nov 24 2021 A cold front completes its sweep across the region this evening with polar air streaming in overnight and setting the stage for a relatively chilly Thanksgiving day. As of 2pm, a well-advertised cold front was knocking on La Crosse's doorstep and should complete its passage through the Upper Mississippi River Valley by early this evening. Thus, have not deviated too far from the NBM deterministic wind speeds for tonight with a leaning towards the HRRR to capture the higher wind gusts. Low-level moisture wrapping around the lower tropospheric low may experience enough synoptic lift ahead of the H500-300 trough to generate light flurries during the overnight hours. With the thermal trough over the region during this timeframe, highs will struggle to reach the mid 20s west to low 30s east.
Tomorrow, a cold front will move across the region and will be accompanied by widespread showers through the late morning and afternoon hours.
716 PM EST Wed Nov 24 2021 High pressure settling in north of Florida is favoring northeast and east winds, with temperatures gradually moderating. High pressure will hold north of the waters through Thursday evening, with generally easterly flow continuing.
533 PM MST Wed Nov 24 2021 An upper level trough will drop to the southeast across the region this afternoon into tonight. Could see a few showers east of the higher elevations. Lows will be in the mid to upper teens over the plains (cooler in the valleys) and single digits to low teens over the higher elevations. Behind the previous system, an upper level ridge moves into the region overnight into Thursday.
315 PM MST Wed Nov 24 2021 As an upper trough axis moves through tonight skies will clear.
509 PM CST Wed Nov 24 2021 Aside from some cirrus to our south, latest satellite imagery shows a fairly narrow stratus deck sliding southeastward over the region in tandem with a sfc cold front. While overall moisture remains largely limited at this time, should see an uptick in the low to mid levels develop by late afternoon/evening. Otherwise, expect afternoon highs to largely remain at or just below freezing, with locations along and west of the James River approaching the upper 30s under southwesterly flow.
438 PM CST Wed Nov 24 2021 Summary: Warmer temperatures this evening in northwestern Wisconsin will decrease significantly as a cold front moves through with the chance for light snow showers and flurries. As the low moves through the area tonight, a chance for some flurries is possible along its cold front. Dry air aloft and a resultant lack of ice crystals in the atmosphere may cause freezing rain/drizzle to fall near the start of the precipitation before temperatures within the mixing layer decrease enough for ice to form lower in the atmosphere. The lake effect precipitation should end by Thursday afternoon as the low departs from the Northland. Though temperatures will begin to slowly increase over the weekend once again as a ridge moves into the region.
552 PM EST Wed Nov 24 2021 Cold and dry Canadian high pressure will hold temperatures below normal through Thursday.
210 PM MST Wed Nov 24 2021 As an upper trough axis moves through tonight skies will clear.
503 PM CST Wed Nov 24 2021 (Tonight) Gusty southerly winds will continue ahead of the cold front which will move into NE OK by late afternoon and continue steadily eastward clearing northwest AR before sunrise Thursday. Guidance remains consistent with a band of showers and storms developing this evening along and immediately behind the advancing cold front and expanding in coverage through the the late evening into early morning hours.
Windy conditions ahead of the upper trough and cold front that will bring rain to the mid state during the day tomorrow.
557 PM CST Wed Nov 24 2021 Low level moisture continues to move into the region in advance of an approaching cold front.
Another chilly morning is on tap for Thanksgiving morning but afternoon highs will warm back to above normal levels tomorrow as high pressure builds into the area.
Warmer again by this weekend as high pressure builds back in from the west. This is due to another shot of energy dropping into the base of the trough already in the vicinity. At the same time, as the colder air begins to filter in aloft later tonight with this next system, snow levels will lower overnight with some light accumulations expected above 8,000 ft, mainly over the higher peaks of the Chiricahua and Pinaleno where 2-4 inches are possible at the tops.
Ensemble guidance in good agreement that high pressure over the Eastern Pacific will move east over California today into the weekend.
The high pressure shifts southeast throughout the day on Thursday, with return flow developing fairly quickly over western South Dakota. Keep high temperatures on the cooler side of guidance in the northeast CWA with reading in the mid 20s.
A warm front is taking shape along the Front Range and will be moving east later on tonight which should stabilize or even begin to warm our temperatures as we get closer to morning.
539 PM CST Wed Nov 24 2021 Summary: Warmer temperatures this evening in northwestern Wisconsin will decrease significantly as a cold front moves through with the chance for light snow showers and flurries. As the low moves through the area tonight, a chance for some flurries is possible along its cold front. Dry air aloft and a resultant lack of ice crystals in the atmosphere may cause freezing rain/drizzle to fall near the start of the precipitation before temperatures within the mixing layer decrease enough for ice to form lower in the atmosphere. The lake effect precipitation should end by Thursday afternoon as the low departs from the Northland. Though temperatures will begin to slowly increase over the weekend once again as a ridge moves into the region.
Dry air remains in place with dewpoints in the lower to upper 20s at this time. This should modify overnight, as low level moisture and warm air advection increases courtesy of a low level jet pushing into the region ahead of a cold front. However, further west, expect lows to drop only into the lower to mid 40s due to stronger winds.
A much cooler airmass will reside across the area through tonight. High pressure will follow for the latter portion of the week, bringing dry and stable conditions.
533 PM EST Wed Nov 24 2021 A cold front with rain can be expected on Thanksgiving.
Quiet weather will continue over the Northern Rockies through Thanksgiving day due to a weak ridge of high pressure. This ridge could allow for the development of patchy river fog by Thursday morning.
658 PM EST Wed Nov 24 2021 Dry weather will continue this evening as high pressure tracks to the East Coast. Widespread rain is forecast for Thanksgiving Day along a cold front traveling from the west.
No change in the forecast with high pressure keeping a quiet weather pattern through the remainder of November, and likely continuing into the first few days of December.
310 PM CST Wed Nov 24 2021 A cold front continues to move through the Great Plains and is expected to begin impacting the CWA on Thursday evening. The moisture is still primarily in the low levels, so despite higher PWAT values, the mid- levels will remain fairly dry up until the actual front moves through.
852 PM EST Wed Nov 24 2021 High pressure will shift south of the area tonight.

929 PM EST Wed Nov 24 2021 Cold and dry Canadian high pressure will hold temperatures below normal through Thursday.
221 PM MST Wed Nov 24 2021 An upper level trough will drop to the southeast across the region this afternoon into tonight. Could see a few showers east of the higher elevations. Lows will be in the mid to upper teens over the plains (cooler in the valleys) and single digits to low teens over the higher elevations. Behind the previous system, an upper level ridge moves into the region overnight into Thursday.
637 PM EST Wed Nov 24 2021 Cold and dry Canadian high pressure will hold temperatures below normal through Thursday.
Current IR satellite data depicts a broken coverage of cirrus spreading across the region this evening, within a west-southwest flow regime to the east of an approaching mid-level trough. As a result of the high-level cloudiness and light/moderate south-southeasterly flow in the low- levels, minimum temperatures will be several degrees warmer compared to previous nights, with readings ranging from the mid 30s in northeast AL to the mid 40s along the AL-MS border.
(The rest of tonight) Cold front has pushed into NE OK as of mid evening.
237 AM EST Thu Nov 25 2021 Latest surface analysis places a center of low pressure of the upper peninsula of MI with a cold front stretching SW into OK/TX. The cold front will push though later this afternoon through the evening with rain turning to a rain/drizzle mix in its wake.
1031 PM CST Wed Nov 24 2021 Aside from some cirrus to our south, latest satellite imagery shows a fairly narrow stratus deck sliding southeastward over the region in tandem with a sfc cold front. While overall moisture remains largely limited at this time, should see an uptick in the low to mid levels develop by late afternoon/evening. Otherwise, expect afternoon highs to largely remain at or just below freezing, with locations along and west of the James River approaching the upper 30s under southwesterly flow.
243 AM EST Thu Nov 25 2021 Cold front currently stretches from the central Great Lakes back through northern TX. High pressure is centered across the Outer Banks and Low Country. The high center will shift southward today as the cold front pushes east of the Mississippi River.

Expect overnight lows to fall broadly in the upper 60s with the coolest temperatures in the Lower and Middle Keys and warmest in the eastern Upper Keys. A weakening high pressure centered near the Carolina coast will drift a bit southwards overnight.
(Today) Early this morning, a cold front extended from near KFYV to KDUA with scattered to numerous showers and a few thunderstorms occurring in the vicinity of the front.
1037 PM EST Wed Nov 24 2021 High pressure will prevail across the region through Thanksgiving Day.
1238 AM EST Thu Nov 25 2021 Dry weather will continue this evening as high pressure tracks to the East Coast. Widespread rain is forecast for Thanksgiving Day along a cold front traveling from the west.
1032 PM CST Wed Nov 24 2021 (The rest of tonight) Cold front has pushed into NE OK as of mid evening.
1235 AM MST Thu Nov 25 2021 As an upper trough axis moves through tonight skies will clear.

1133 PM CST Wed Nov 24 2021 Summary: Warmer temperatures this evening in northwestern Wisconsin will decrease significantly as a cold front moves through with the chance for light snow showers and flurries. As the low moves through the area tonight, a chance for some flurries is possible along its cold front. Dry air aloft and a resultant lack of ice crystals in the atmosphere may cause freezing rain/drizzle to fall near the start of the precipitation before temperatures within the mixing layer decrease enough for ice to form lower in the atmosphere. The lake effect precipitation should end by Thursday afternoon as the low departs from the Northland. Though temperatures will begin to slowly increase over the weekend once again as a ridge moves into the region.
217 AM CST Thu Nov 25 2021 A strong cold front plowed south across the forecast area last night, with much colder air moving into the area. Expect minimal travel concerns for today, as a Canadian ridge of high pressure builds into the region, with temperatures slightly below seasonal normals.
111 AM CST Thu Nov 25 2021 High level cloud cover was overspreading the area in advance of an upper trough and cold front. High pressure was located across the Carolinas and was keeping a dry and stable airmass in place over the TN valley. Wind gusting to 20-25kt is likely overnight, especially in the higher elevations.
113 AM EST Thu Nov 25 2021 Cold and dry Canadian high pressure will hold temperatures below normal through Thursday.
214 AM EST Thu Nov 25 2021 A rain with a crossing cold front can be expected on Thanksgiving.
The rain will be associated with a surface cold front and mid level trof moving across the area today.
Early this morning, an upper trough axis was across Minnesota down to Nebraska. A surface cold front was across northwest Illinois. Isentropic lift along with forcing from the upper trough and the cold front itself will continue to produce rain this morning as the cold front moves through. Widespread rain at any location will cut off after the cold front passes. Weaker forcing will continue ahead of the upper trough axis passes, and some lake enhanced showers may sneak into the area as colder air moves in later this afternoon into the evening (mainly northeast). Temperatures will peak ahead of the cold frontal passage, then fall some behind it. Readings will be in the upper 30s northwest to the lower 40s most other areas by sunset.
