High winds may impact the Little Rockies at times this afternoon through Friday morning, expect gusty winds on Fort Peck A warm front will track east across the region today, with increasing west winds beginning this afternoon for NE Montana. The High Wind Watch previously in effect has now been replaced with a High Wind Warning. For the high wind, even if observations do fall just shy of criteria, impacts will likely be higher than otherwise would be due to the increased travel this evening. For this weekend, upper ridging will prevail, allowing for mainly dry and mild temperatures.
Cooler temperatures and gusty northeast winds are expected through Thanksgiving Day, with a warming trend and mild weather through the weekend.
The eastern slopes of the Cascades and northern mountain valleys will see a mix of rain, freezing rain, and snow through morning. Today through Friday: The warm front is currently pushing through the region. Through the early morning hours, below freezing surface temps and warmer air aloft is creating potential pockets of freezing rain for the lee of the Cascades including the Methow Valley. For Friday, a cold front will be swinging through the area and decreasing the shower chances across the region. With the cold front passage, winds will be breezy across the Basin with gusts around 25 MPH. OVernight lows will dip behind the cold front with upper 20s and low 30s.
436 AM EST Thu Nov 25 2021 A rain with a crossing cold front can be expected today. A few snow showers are possible Friday under upper level low pressure. Rain will begin to develop over the entire area as the trough advances out of the Midwest toward the Upper Ohio Valley region. That situation looks to improve on Friday, but dry ambient advection and sheared boundary layer flow look to limit problematic totals for the ridges and lake zones at this time.
(Today through Friday afternoon) The cold front has quickly moved s to near the I-10 corridor with ne winds of 15-20kts in its wake. Satellite continues to show an abundance of high clouds for today and high temps will be about 15-20 degrees cooler than yesterday with M50s common this afternoon. Into Fri AM said high clouds will likely hang around s of I-20, however a 1033 mb surface anticyclone will be settling in around 09Z/Fri and a widespread light freeze is expected for areas n of I- 20 and hard freeze for parts of Lea, Gaines, Dawson.
/Issued 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. High pressure will build back in from the west on Friday.
Upper level ridge will build over NorCal and strengthen into the holiday weekend. High temperatures will generally range from the low to upper 60's for Valley locations, possibly low 70's over the northern Sacramento Valley(Redding area).
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. Lows tonight will be in the lower 20s, with highs on Friday only in the 30s.
/issued 403 AM CST Thu Nov 25 2021/ Showers and a few isolated thunderstorms are pushing into the forecast area this morning as a cold front will move through the Mid South.
Zonal pattern aloft returns through mid week with high pressure at the surface settling into the SE U. High pressure builds into the area through mid week with mostly sunny conditions expected under a N'ly breeze with seasonal to slightly cool highs moderating from the mid 60s-70s into the 70s by mid week. High pressure over the eastern U.
Some high/mid level cloudiness will be associated with the warmer air evading the region, but no precipitation is expected.
513 AM MST Thu Nov 25 2021 12Z TAF CYCLE The back door cold front whas moved through the Rio Grande Valley overnight and will make it to the Continental Divide this morning.
The cold front will push through tomorrow, with snow starting to mix in late afternoon.
742 AM EST Thu Nov 25 2021 A rain with a crossing cold front can be expected today. A few snow showers are possible Friday under upper level low pressure. No changes were needed for the morning update as rain will begin to develop ahead of an approaching longwave trough/cold front. That situation looks to improve on Friday, but dry ambient advection and sheared boundary layer flow look to limit problematic totals for the ridges and lake zones at this time.
In addition to that, the High Wind Warning for the Rocky Mountain front and eastern Glacier County was extended through noon Friday. Weak ridging/zonal flow will continue building in behind an exiting trough. The lowest part of the atmosphere will be quite dry however, which makes me favor virga over precipitation reaching the ground in most areas.
A slight warming trend will occur through the weekend with high pressure moving into the region. However, the high resolution guidance in general shows a delay in onset of valley fog development along with less coverage of dense fog, compared to this morning and last night. The blended guidance shows a probability of at least freezing temperatures at these locations near 75 percent, though decline to about 30 to 40 percent for readings at or below 28 degrees. So, temperatures at or just below freezing are quite likely.
330 PM EST Thu Nov 25 2021 A cold front will move across the region overnight.
That plus some sunshine should help boost temps back well above average for late November with many spots getting above freezing and some locations in southeastern ND even up above 40 degrees. Cluster analysis for the next several days show a strong signal of a ridge out west retaining its strength prompting NW flow in the Northern Plains.
340 PM EST Thu Nov 25 2021 Showers are likely late tonight into early Friday as a cold front moves across the area.
245 PM EST Thu Nov 25 2021 A cold front will move across the region overnight.
Satellite derived TPW shows very dry air associated with the anticyclone. Most of the moisture sampled was confined below 825 mb, and a few shallow showers have been able to capitalize on this lower-level moisture. Temperatures are in the lower 70s, there is abundant sunshine, and winds have abated since yesterday. From synopsis, high pressure over the Carolinas will slide south over the Florida peninsula and weaken through tonight.
This and some warm air advection ahead of the front should allow temperatures to climb into the lower 60s in many areas east of this leading precipitation this morning into the early afternoon hours before cloud cover and precipitation move in. Wind gusting to 20-25kt is likely overnight, especially in the higher elevations.
1115 AM CST Thu Nov 25 2021 An upper level trof continues to move eastward into the the upper midwest. Winds will turn to the southwest and a warm front will push through western and southwest Nebraska Thursday, which will help keep temperatures a little warmer with highs in upper 40s to low 50s. As for Friday warmer air moves back into the area behind the front, pushing temperatures around 20 degrees or more above normal.
1137 AM CST Thu Nov 25 2021 (Today and tonight) Gusty northerly winds will continue across the area this morning keeping temperatures in the low 40s until noon today.
Ridge tops to the east will also see very strong wind gusts, but not expected to reach 60 mph. RAE 3am discussion: A warm front will track east across the region today, with increasing west winds beginning this afternoon for NE Montana. The High Wind Watch previously in effect has now been replaced with a High Wind Warning. For the high wind, even if observations do fall just shy of criteria, impacts will likely be higher than otherwise would be due to the increased travel this evening. For this weekend, upper ridging will prevail, allowing for mainly dry and mild temperatures.
Sky cover will gradually decrease over southern areas today, then begin to increase in coverage again on Friday as an upper level low pressure system over the Baja Peninsula shifts eastward over northern Mexico.
209 PM EST Thu Nov 25 2021 High pressure over the Southeast states will shift offshore later today. A cold front will approach from the west this evening then cross central NC tonight.
Clouds and some slightly warmer temps are on the way, with readings already in the teens across western ND. Should see the slightly warmer temps start to move into our far west by mid- day and top out in the teens and 20s this afternoon. Our warmest locations will be west of the Red River, where temperatures could reach the lower to middle 20s. Winds shift through the midday and afternoon hours, allowing warmer air to slowly work northward heading into the evening and overnight period. Friday will be significantly warmer, with upper 20s for highs near Lake of the Woods, and low 40s near Valley City. This warmup is in response to the approach of an H5 ridge building into the northern US Rockies, then slowly working eastward.
Look for quiet and dry weather to continue through the weekend as high pressure remains in control.
A cold front extends from northeast to southwest across the Delta this afternoon, with showers occuring mainly along and out ahead of it. High pressure and drier/cooler conditions will build in behind the boundary overnight. Lows tonight will range from around 30 degrees in the north to the low 40s in the south.
Today through Friday Overall, the Turkey Day forecast is quiet with not a whole lot to gobble about in the near term as ridging builds into the weekend. Ridging will continue to build into tomorrow, with afternoon southwest winds across the usual areas and a continuing warming trend.
Heading into the overnight period, expect lingering cirrus along with southerly/southeasterly flow to keep Friday morning lows a touch warmer than this morning, as temperatures only fall into the teens to 20s. Nonetheless, could still see wind chill values approach the lower teens to single digits in areas east of I-29, so we encourage you to bundle up before heading outdoors! Despite a somewhat chilly start, expect temperatures to rebound quickly as a warm front lifts over the region.
Otherwise, each day from Friday through next Thursday will be a virtual repeat with highs warming to the upper 50s-lower 60s in most areas, and typical cool nights/mornings with lows mainly from near 20 degrees to the lower 30s.
After sundown, high surface pressure will start building as our cold upper trough axis makes its way through. As winds go light and variable after sundown under clear night skies and within a cooler air mass, will expect strong radiational cooling to begin. Expecting most of our areas temperatures to eventually drop below freezing, although not expecting much of a wind chill as winds should stay near calm. Did go slightly cooler with the MinT using the NBM 25th percentile. Our western CWA could even become a little bit warmer being more downwind of the Texas Panhandle. As a result, went slighlty warmer than NBM using the CONSMOS for Fridays MaxT.
It still looks as though precipitation will move southeast of the area before temperatures drop to near freezing behind the front. With winds become light Friday night and clear skies expected, good radiational cooling is expected with high pressure overhead. Models trending slightly cooler again today.
No updates to the current forecast but the main upper ridge over the western US will flatten later today and tonight as a weak Pacific upper trough passes through the northern part. Several models produce small amounts of pcpn tonight with the trough, although most models stay dry. Ridge will rebuild Friday as the trough exits east, but a warm front will come in from the Pacific Friday with a chance of rain in northern areas.
154 PM CST Thu Nov 25 2021 Bitterly cold air has been pouring into Iowa today, and as it's advected into Illinois through the day, it's been modified to the lower 30s.
A ridge will begin to expand from the West Coast to the central Rockies, which keeps us dry for the next few days and causes temperatures to moderate.
1110 AM CST Thu Nov 25 2021 (Today and tonight) Expect much cooler and breezy conditions today behind a cold front.
This activity has been ongoing along and ahead of a cold front that is currently located from ERN OK into NWRN AR and SRN MO.
132 PM CST Thu Nov 25 2021 A cold Canadian high pressure ridge will slide southeast into the lower Ohio Valley tonight and Friday, bringing clearing skies and much colder temperatures to the region. The chilly high pressure center will move off to the east as we head into the holiday weekend.
This will aid in the quick warming of the lower troposphere which will support afternoon temperatures well into the mid to perhaps upper 60s for highs across nearly all of the southwest, west central, and south central Kansas region.
A weakening cold front will move into inland southeast Georgia after midnight.
A pre-frontal trough is moving across middle Tennessee.
17z/11am surface analysis shows a cold front well to the east across Indiana. The cold front as of 3am was situated just to the west of I-57 corridor. Ahead of the front, southerly winds continued to usher warmer temperatures in the mid 40s to low 50s, while behind the front, northwesterly winds began to usher cooling temperatures across western Illinois. Heading through today, the upper level trof axis will shift through the region, helping to rapidly move the frontal system out of the Midwest into the Ohio Valley and east coast.
214 PM CST Thu Nov 25 2021 A cold front is slowly diving eastward towards Monroe County. Behind the cold front cooler air is filtering in with temperatures beginning to fall. Lows tomorrow night will be a tad warmer than tonight.
(This afternoon through Friday night) Temperatures are a good 15-20 degrees cooler now compared to yesterday thanks to the cold front that moved through overnight. Winds this afternoon are still on the elevated side, but we'll see those relax over the next 3-6 hrs as high pressure quickly moves overhead for the overnight time frame. Upper low over Mexico will finally scoot eastward Friday night with increasing shower chances moving NE into the remainder of the forecast area.
This moisture is confined to the lower-levels due to a strong inversion around 825 mb. The aforementioned high pressure will be shoved off the southeast coast by an approaching upper-level trough. The high pressure will elongate and the ridge axis will settle across Florida on Friday ahead of the frontal boundary associated with the upper-level trough. This is more of a re-enforcing cold front to keep these comfortable conditions around through the weekend.
Cold front is just starting to inch its way into the northwest zones this afternoon, and will also work its way across the area.
1137 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.
High clouds are building across the area as high pressure moves away, and winds become westerly. A clipper type system will move through the region at the start of the period in association with the passage of an upper s/w trough.
Subsequent high level cloud cover across much of the area will moderate high temperatures in the low 60s down south to the mid 60s up north.
A pre-frontal trough is moving across middle Tennessee. A cold front will move through the region this afternoon/evening which will prompt increased sky cover and lowering cigs amidst shra.

227 PM EST Thu Nov 25 2021 A cold front will move across the region overnight.
A cold front is moving into the Delta this morning with widespread rainshowers, mainly along and north of the Natchez Trace Corridor. Dry conditions look to remain in place until a little after daybreak, where a line of showers accompanied with a cold front will begin to propagate E-SE through the region. By the late evening into the overnight hours, rain should be on its way out of the area with cooler air pooling in behind it. By tonight, overnight lows will drop to freezing for those along the Highway 82 corridor.
At forecast time, thanks to decent southerly flow all day, we're 20+ degrees warmer than we were at this time last night.
1243 PM EST Thu Nov 25 2021 Rain with a crossing cold front will transition to snow showers for later tonight and Friday.
At the surface, a broad, 1036 mb anticyclone is settling into the OK/TX Panhandle region as post-frontal, northerly winds diminish in intensity as the pressure gradient loosens. The surface anticyclone is forecast to be centered over the eastern Permian Basin into the Edwards Plateau by 26/12Z, with winds prevailing out of the west across the CWA by then. Vertical mixing heights are forecast to ascend to around 1-km AGL tomorrow afternoon as West Texas will remain under the influence of split flow aloft, contributing to a modest increase in theta-e with height between 700-850 mb and light southwesterly winds generally around 10 mph or less as the surface anticyclone moves into eastern Texas.
Showers and a few isolated thunderstorms are pushing into the forecast area this morning as a cold front will move through the Mid South.
Light south winds will develop from west to east across the area overnight but still expect lows to drop a bit colder than NBM so have kept mins toward the lower end of the guidance. Low pressure will develop across the northern high plains Friday with southwest winds of 5 to 15 mph expected across the area along with some passing mid clouds.
A cold front will move through the region with scattered light showers late Thursday night and Friday morning. Dry weather will remain in place but temperatures will be warmer than the previous day ahead of an approaching cold front. A cold front will push into the Appalachians this evening then across the forecast area overnight. There will be a modest increase in moisture ahead of the cold front with precipitable water values increasing to near 1. Winds become calm late Friday which combined with clear skies will lead to favorable radiational cooling with temperatures dropping below freezing across the entire forecast area.
428 PM MST Thu Nov 25 2021 The cold northwest flow pattern will slowly exit the area through Friday as a northeast-oriented ridge of high pressure pushes into the Great Basin region. As a result, expect seasonably cool temperatures tonight and Friday night under mostly clear skies and slightly warmer afternoon high temperatures on Friday with partly cloudy skies across the north with mostly sunny skies expected across the south.
Outstanding Thanksgiving wx continues across SE Idaho, courtesy of a longwave ridge of high pressure dominating much of the wrn US. HREF- projected RH values as well as HRRR/MOS guidance are far too dry tonight to support fog/low stratus concerns outside of normal localized problem spots adjacent to water sources, such as Osborne Bridge in Fremont County. We did bite and broke ranks with the NBM on this advertising a progressive zone/band of light 15-25% PoPs calibrated to the HREF consensus as well as one of the high-res blends, but impacts should be very low with zero accumulation expected out of this activity and just an increase in cloud cover.
Mostly clear and warmer temperatures tonight with lows in the upper 20s/low 30s across the lower elevations and teens/20s over the higher elevations. An upper level ridge pushes further eastward into CO Friday further promoting dry and mild conditions. Meanwhile a cold front will move across northeast Colorado early on Sat with temps dropping back to more seasonal levels. On Sun, it will be dry and warmer, with highs rising into the lower to mid 60s, over the plains.
The clearing line behind today's cold front currently extends from near Batesville (MS), to Jackson (TN), to Paris (TN) and will continue to move east overnight with clear skies anticipated before sunrise. /issued 214 PM CST Thu Nov 25 2021/ A cold front is slowly diving eastward towards Monroe County. Behind the cold front cooler air is filtering in with temperatures beginning to fall. Lows tomorrow night will be a tad warmer than tonight.
Northwesterly winds are currently gusting 25-30mph: however, as high pressure builds eastward, winds will slowly decrease to less than 10mph overnight.
as a cool airmass remains behind yesterdays cold front. which will help to modify temperatures as a warmer airmass is advected across the local area.
632 PM EST Thu Nov 25 2021 A cold front will move across the region overnight.
A cold Canadian high pressure ridge will slide southeast into the lower Ohio Valley tonight and Friday, bringing clearing skies and much colder temperatures to the region. The chilly high pressure center will move off to the east as we head into the holiday weekend.
216 PM MST Thu Nov 25 2021 The cold northwest flow pattern will slowly exit the area through Friday as a northeast-oriented ridge of high pressure pushes into the Great Basin region. As a result, expect seasonably cool temperatures tonight and Friday night under mostly clear skies and slightly warmer afternoon high temperatures on Friday with partly cloudy skies across the north with mostly sunny skies expected across the south.
North winds are picking up with the cold front passage this evening, sustained in the 10-15 kt range with gusts 22 to 25 kts.
These conditions will help keep temps 10 to 20 degrees warmer tonight than last night with temps remaining steady or slightly climbing in the east after a quick drop this evening. That plus some sunshine should help boost temps back well above average for late November with many spots getting above freezing and some locations in southeastern ND even up above 40 degrees. Cluster analysis for the next several days show a strong signal of a ridge out west retaining its strength prompting NW flow in the Northern Plains.
129 PM PST Thu Nov 25 2021 High pressure will dominate our weather pattern the next several days. This pattern will bring light winds, reduced humidity, and warmer daytime temperatures. Latest model guidance shows the high clouds will increase further overnight. Therefore, overnight lows tonight will be a tad warmer. Otherwise, high pressure will build overhead leading to a slight warming trend through the weekend. Not a strong or even moderate offshore gradient, but enough for warmer conditions with less nighttime fog. KSFO Bridge Approach. Light to moderate winds will prevail into the weekend as high pressure dominates the region.
High pressure was bringing mainly sunny skies to the Northland this Thanksgiving in the wake of a cold front that brought an extra helping of cold air to the region this morning.
431 PM EST Thu Nov 25 2021 A cold front will move across the region overnight.
747 PM EST Thu Nov 25 2021 Early evening IR and water vapor satellite imagery is showing relatively dry air over the Florida Peninsula ahead of an approaching dry cold front moving into the western Gulf of Mexico. High pressure over the coastal waters will shift east into the Atlantic on Friday ahead of an approaching cold front.
