This will ultimately result in warmer than expected high temperatures today. Tonight mostly clear skies will allow nocturnal cooling to maximize with lows falling into the 20s across the entire area with the exception of our very far southern counties where temps bottom out in the low 30s.
The upper level trough driving Thursday's sensible weather digs southeast, providing the weekend weather maker for the East Coast while placing us in the cold sector with northerly cold air advection Thursday night. Model soundings indicate winds will remain elevated in the early evening hours, staving off surface temperatures dropping drastically before the high pressure sits overhead by the morning hours.
The next trough will swing into the area late this evening and overnight and bring another bout of snow.
254 PM CST Wed Jan 26 2022 Another mostly clear and cold night will be in store for the Tennessee Valley once again as high pressure centered over the Plains remains in control of our weather. Lows tonight will bottom out in the low to mid 20s. The combination of a still mostly clear sky and southerly flow will help to warm our temperatures about 10-15 degrees higher than today -- and into the low to mid 50s by the afternoon.
(This evening through Thursday) Some moisture has been observed filtering into West Central texas this afternoon, which should persist through this evening as the upper-level trough tracks easterly across the region. As of 2PM today there haven't been many observations showing precipitation reaching the ground up in the Big Country and northern portions of the Concho valley, mainly due to much drier air at the lower levels (Dewpoint temperatures in the single digits in some places). Expect cold overnight lows in the mid 20s (Big Country) to the upper 30s (South of I-10), which if fog develops over an area below freezing, can develop into freezing fog.
Gradual warming has occurred with temperatures in the lower 30s in the north, still below freezing, to the mid and upper 30s in the Pine Belt. /28/ Prior discussion below: Today and Tonight: In the wake of yesterday's cold front passage, today will be cool, dry, and sunny.
(The rest of today ) Upper low currently over New Mexico will continue to shift eastward throughout the day and weaken some as it does so. Precip will likely begin as rain as temperatures are expected to be above freezing, but quickly change to snow within the heaviest precipitation.
weather map shows upper troughs moving through the northeast and portions of southern Canada while closer to home water vapor shows a compact upper trough moving through the southern Rockies and the Texas Panhandle. With low level flow increasing as the upper trough passes to our north, the clouds will stick around throughout the night, tomorrow and into Thursday night.
High pressure at the surface will bring clear skies, and VFR conditions for the next 24 hours.

1257 PM EST Wed Jan 26 2022 Dry and colder Canadian high pressure settles across the region through Thursday.
307 PM EST Wed Jan 26 2022 Stationary front in place across the central zones with the low in place across south FL this afternoon. The low will continue to shift east across the peninsula, with the boundary shifting south of the area as weak high pressure builds in tonight and Thursday. The low clouds will linger through tomorrow morning, then should lift and scatter out through the day.
Northerly flow is reinforcing cooler and drier air into the region with precipitable water values sitting around 0. With mostly sunny skies, will see sufficient daytime heating, causing temperatures to rise into the lower to mid 50s inland with upper 50s along the Florida Panhandle. Breezy conditions will continue through the afternoon, but should start to relax overnight as the pressure gradient weakens and high pressure builds in. The HIGH risk of rip currents will remain in effect through this afternoon, then becoming a MODERATE risk tonight and Thursday due to decreasing swell.
Warmer and quiet weekend. At mid afternoon high pressure was centered over western Illinois, with sunny skies across much of the area. With the clouds and a return to a more southerly flow on the back side of the high overnight lows will range from the lower 20s over the eastern Ozarks, to near 30 over southeast Kansas and western Missouri. The wave will exit quickly on Thursday morning, but clouds will linger across the area as a cold front pushes through during the afternoon hours. Temperatures will rebound into the low to mid 40s for afternoon highs, as the colder air will lag behind the front.
Lows Thursday morning will range from the high single digits across parts of the Bluegrass and southern Indiana to the high teens along and south of the Cumberland Parkway. At present, model soundings indicate that the lowest layers of the atmosphere will be very dry, especially south of the Ohio River. Therefore, have only gone with slight chance PoPs with the highest PoPs in southern Indiana. Otherwise, temperatures will be warmer across the region tomorrow as milder SW return flow sets in over the area.
1030 AM EST Wed Jan 26 2022 Made some minor adjustments to temps and POPs to better account for current conditions, but forecast is generally on track with the low gradually moving across the southern peninsula this afternoon and gradual clearing occurring Thursday as weak high pressure builds in between systems. SCEC will continue across the central and northern offshore waters this afternoon, with showers gradually ending as the low shifts south and east of the waters.
An approaching cold front will bring a swath of light snow showers and flurries to the region later tonight and Thursday as it pushes through the area Thursday morning. High temperatures on Thursday will depend on the timing of the cold front. North-central Wisconsin will likely see their highs in the morning, with falling temperatures throughout the rest of the day behind the cold front. Central Wisconsin will likely see their highs later in the morning while east-central and northeast Wisconsin somewhere around midday, with falling temperatures for the rest of the day behind the departing cold front.
As of 2 pm this afternoon, the warm front was pushing through portions of the Red River Valley. This warm spell will be very short lived, as the next cold front is already poised along the Canadian border. This cold front will sweep southward into the northern FA by early evening.
1125 AM EST Wed Jan 26 2022 Weak low pressure will cross south central FL this afternoon riding along a frontal boundary that extends SW-NE across our southern counties and over our southern marine zone. A mid/upper level trough will drop through the Northeast today. Will see shower chances diminish into the afternoon, mainly west of I-95 and north of Okeechobee County, as the low begins to pull away from the area and winds veer northeasterly. PoPs 30-40% there by late afternoon, though have up to 50% across Martin County, which will be closest to the surface front associated with the low. Temperatures remaining below normal this afternoon, as highs rise into the low to mid-60s from Titusville/Kissimmee northward and upper 60s to low 70s to the south.
Surface temps will have risen above freezing in most places by the time precip gets here, suggesting it could start off as rain.
1023 AM MST Wed Jan 26 2022 Current surface analysis shows warm front moving east across western SD, with temps slowly rising in many areas behind it. Upper level analysis shows large scale trough over the eastern US, with northwest flow from the western US through the midwest. Cold front across central Canada will slide south- southeast into the Northern Plains later tonight and Thursday. Froude number suggests the more significant snowfall will develop over the higher slopes of the northern BH, where a few inches of snowfall is likely late tonight into Thursday afternoon.
High pressure centered to our north will allow for northerly winds from 5 to 12kts through early evening. The high shift east just beyond this TAF issuance and winds will then turn southerly. High pressure at the surface will bring clear skies, and VFR conditions for the next 24 hours.

The Florida Keys remain in the warm sector of a gradually weakening and broadening low pressure system currently centered over the southeastern Gulf of Mexico. Surface winds have been blowing steady from the south-southwest, with air temperatures currently in the upper 70s and dewpoint temperatures in the lower 70s. Moderate to fresh southerly breezes will become southwest to west and weaken this afternoon, as low pressure over the southeastern Gulf of Mexico degenerates into a trough.
249 PM CST Wed Jan 26 2022 Temperatures this afternoon are a solid 15 to 20 degrees warmer than yesterday with pretty widespread sunshine allowing the light snowcover to melt away. Tonight, winds will shift to the northwest as an upper trough and associated cold front push through the area. Behind this cold front, we will see breezy northwest winds on Thursday afternoon (gusts 20-30 MPH). Flurries were added to the forecast for Thursday night as several models are showing some spotty light QPF in response to as secondary trough passage and the upper level jet nosing into the area.
300 PM CST Wed Jan 26 2022 Upper level low pressure trough will cross the region late this afternoon and early this evening. RMcQueen Surface ridging will nose in from the north behind our next front on Thursday evening, providing another chilly night with lows in the teens and lower 20s.
1236 PM EST Wed Jan 26 2022 Bitterly cold temperatures expected through tonight as Arctic high pressure builds in.
235 PM EST Wed Jan 26 2022 Dry and cool Canadian high pressure settles across the region through Thursday.
103 PM CST Wed Jan 26 2022 High pressure over the area continued to result in mostly clear skies and cold conditions today.
Otherwise, a northern stream upper trof will settle southward across the north central conus late tonight into Thursday. The associated surface trof/weak cold front will likewise move southward across Kansas. As winds become light near the surface trof/front, a combo of radiative and advective processes may lead to some freezing fog, mainly over the residual snow cover in parts of central and south central Kansas toward dawn.
330 PM EST Wed Jan 26 2022 High pressure will build across the region through Thursday.
Otherwise the forecast remains on track, with snow expected to overspread portions of North Central through Southwest Montana this afternoon and through the overnight hours in wake of a passing cold front. - Moldan 1010 AM MST Wed Jan 26 2022 (26/18Z TAF period) VFR conditions are expected through 00-06z Thursday ahead of a weak cold front; thereafter a transition to MVFR, and at times near-IFR, conditions are expected until 12-18z Thursday. CIGS will lower this evening and during the overnight hours in wake of the aforementioned cold front, in addition to snow developing and persisting in northerly upslope favored regions.
The low ceilings may also create slick spots on elevated surfaces. Overnight Wednesday, low temperatures will fall into the low teens to lower 20s. Thursday, another trough moves through the region from the northwest. A colder air mass moves in behind this trough with western portions of the CWA falling into the single digits for overnight lows. The forecast period begins with northwest flow aloft over the Tri- State area and a ridge over the Western CONUS. Dry conditions are expected to persist as the ridge remains present over the west through the weekend. Have kept temperatures quite a bit cooler in areas receiving a foot or more of snowfall from the latest storm system to move through.
Another cold air reinforcement will be rushing out of Canada tomorrow ahead of a trough axis. A cold front will move through our area Thursday night.
The zonal flow aloft will persist today as strong high pressure moves southeast into the Ohio River Valley region. Lows will range from the mid 20s northwest to around the freezing mark far southeast. Highs will range from the low 50s north and northeast to the upper 50s south and southwest.
A post-frontal air mass will continue to settle across northern Arizona today as an upper level low continues to depart into New Mexico. The trough that brought chilly winds to the region yesterday and snow showers along the eastern Mogollon Rim, in the White Mountains and along the New Mexico border continues to move east out of the area with showers in Apache County ending by mid morning. Winds will decrease through the day as the low pushes farther east.
/Issued 1105 AM EST Wed Jan 26 2022/ Temperatures have trended warmer with dew points trending drier have made changes according to these trends this morning. Main concern for today will be potential for fire danger as dry air advects into the area behind yesterday's cold front.
A dry northerly flow aloft remains over the region with a strong high pressure ridge anchored off the coast.
There will be a weak sfc trof that will fragment and move across the FA during the early morning hours. For tomorrow, weak high pressure will prevail. Warmer readings elsewhere. Lastly, there was a minor concern if freezing fog could develop during the morning hours as cold/moist air blows off the snowpack.
127 PM EST Wed Jan 26 2022 An upper level trough will drift across the region this morning before lifting northeast across Upstate New York and New England tonight and Thursday.
1105 AM EST Wed Jan 26 2022 Temperatures have trended warmer with dew points trending drier have made changes according to these trends this morning. Main concern for today will be potential for fire danger as dry air advects into the area behind yesterday's cold front.
Otherwise the forecast remains on track, with snow expected to overspread portions of North Central through Southwest Montana this afternoon and through the overnight hours in wake of a passing cold front. Weak Canadian cold front moves south of the border early this evening bringing low clouds and areas of snow for IFR/MVFR conditions at times over the plains.
321 PM EST Wed Jan 26 2022 Bitterly cold temperatures are expected through tonight under high pressure.
1159 AM EST Wed Jan 26 2022 Cold air remains around the area between now and the weekend with only a slight warm up on Thursday ahead of a cold front.
242 PM CST Wed Jan 26 2022 Gusty southerly winds have developed this afternoon as Arctic high pressure continues to slide off to the southeast. temperatures eventually bottom out around in the lower teens by Thursday morning, with northwest winds likely leading to yet another period with hazardous wind chills below -25 degrees.
High pressure will provide mainly clear skies and frigid temperatures and wind chills tonight into Thursday morning.
High pressure on Thursday with continued sunny and mild weather.
633 PM EST Wed Jan 26 2022 Aviation - Some impacts look possible Thursday due to the snow A positively tilted mid level trough pushes eastward through the CWA on Thursday.
515 PM CST Wed Jan 26 2022 Gusty southerly winds have developed this afternoon as Arctic high pressure continues to slide off to the southeast. temperatures eventually bottom out around in the lower teens by Thursday morning, with northwest winds likely leading to yet another period with hazardous wind chills below -25 degrees.
A weak cold front will bring a period of light snow to primarily the mountains from this evening and through Thursday morning. Low temperatures tonight are expected to fall closer to climatological norms in wake of the front, with temperatures rebounding into the low 30s to low 40s for the day on Thursday.
Thursday many valleys will see brief sunshine before the low clouds redevelop and continue into the weekend.
Have broadened the coverage of patchy freezing fog throughout most lower elevation areas to cover the remainder of the evening as well as the overnight hours. Visibilities so far appear to be remaining above 1/4 mile, so will continue to hold off on a Freezing Fog Advisory for now, but will issue if observations indicate that visibilities are dropping significantly. Current satellite imagery shows a very weak cold front moving through the area, just moving through Hailey and Idaho Falls currently. This very weak system is breaking down the high pressure slightly. High pressure will quickly build back in this evening. Expect patchy freezing fog starting this evening. Thursday expect clear skies for mountains and stratus for valleys with dry conditions under high pressure.
We will initially see a mix of VFR to MVFR conditions at most sites as the wwd extent of the low cloud deck erodes temporarily. (This afternoon through Thursday night) Current WV satellite shows the wintry precipitation has completely moved out of SE New Mexico, with the upper level trough pivoting and the moisture now over the northern counties in the Permian Basin. We are currently looking at the possibility of some freezing fog Thursday morning given models agreement on RHs > 98% and temperatures in the 20s.
633 PM EST Wed Jan 26 2022 High pressure will build across the region through Thursday.
324 PM MST Wed Jan 26 2022 The forecast focus in the short term is on the transient low pressure trough aloft moving across the region on Thursday that will bring a chance of light snow to the western sections of the forecast area. Eastern Colorado may see a few tenths of an inch of new snow on Thursday as the upper trough moves across. As skies clear out Thursday night in the wake of the exiting upper trough, low temperatures are expected to drop into the teens with dingle digits above zero along the axis of the recent significant snowfall.
534 PM CST Wed Jan 26 2022 High pressure over the area continued to result in mostly clear skies and cold conditions today.
Latest radar mosaic showing the first round of up to moderate intensity snow off the high plains starting to move into southwestern Oklahoma. By late evening, most of our area should lie west of the trough axis with the mid-level ascent weakening and the snow concluding. Did go slightly cooler than NBM with the CONSRAW Thursday afternoons MaxT due to a likely snowpack, especially across our west.
A dry cold front will cross Utah and southwest Wyoming tonight into Thursday morning.
449 PM MST Wed Jan 26 2022 pper level analysis shows large scale trough over the eastern US, with northwest flow from the western US through the Great Plains. Surface analysis has a warm front east of the Dakotas with a weak front/trough extending through western South Dakota; all of these features orginiate from an upper low across central Canada. Skies are mainly clear to partly cloudy with temps ranging from the mid 30s to the lower 40s. For tonight and Thursday, the cold front across central Canada will slide south-southeast into the Northern Plains. Should see a few inches of snow in the highest elevations of the Black Hills tonight into Thursday afternoon.
Overnight lows are forecast to bottom out in the lower to mid 20s. A gradual warm-up is expected into the weekend as an amplified, mid level ridge across the western states weakens and moves eastward. Downsloping should mix warmer western temperatures into the region with highs in the 40s and 50s likely.
High pressure will continue to result in areas of fog and low clouds--especially in the night and morning hours. A cold front will reach the area over the weekend.
Behind the cold front this evening, winds are likely to pick up again in the Sisseton Hills and then into west central MN as the winds shift to the north on Thursday. Models have been struggling with the low QPF event on Thursday associated with caa and a weak low moving through central SD. The high will bring in much drier air cutting off the potential for snow showers, but good lift along the western edge of the arctic push will enhance showers.
234 PM PST Wed Jan 26 2022 Blocking high pressure will likely maintain dry and generally quiet weather through the end of January.
This will moderate the low temperatures across the snow covered valleys that have been plagued by inversions. By late morning the trough will begin to pass overhead and mark the peak of the snowfall rates. As the trough progresses southward so will the higher snowfall rates. Snow will be most likely in the higher valleys and mountains mainly along the Divide. Dry environments over the lower valleys will favor deeper mixing, especially along the frontal boundary. By late evening the trough exits the area and snow showers diminish by midnight for most locations.
939 PM EST Wed Jan 26 2022 Bitterly cold temperatures are expected through tonight under high pressure.
/22/ Cool, but dry conditions have prevailed today with plenty of sunshine thanks to high pressure prevailing at the surface. Heading into tonight, a weak mid-level trough will swing through the region. Slightly warmer temperatures will occur tomorrow with a range of the lower 50s in the north to the upper 50s/around 60 in the south.
958 PM EST Wed Jan 26 2022 High pressure will build across the region through Thursday.
/issued 307 PM EST Wed Jan 26 2022/ Stationary front in place across the central zones with the low in place across south FL this afternoon. The low will continue to shift east across the peninsula, with the boundary shifting south of the area as weak high pressure builds in tonight and Thursday. The low clouds will linger through tomorrow morning, then should lift and scatter out through the day.
This evening a clipper system will move across the region bringing light snowfall and possibly some freezing drizzle at times. Temperatures will continue to fall throughout Thursday as a cold front sinks south. This will likely result in some brief freezing drizzle, however, little to no ice accumulation is expected. Temperatures will continue to warm through the evening until a cold front pushes south of the International Border after midnight.
931 PM EST Wed Jan 26 2022 Bitterly cold temperatures are expected through tonight under high pressure.
Temperatures this afternoon are a solid 15 to 20 degrees warmer than yesterday with pretty widespread sunshine allowing the light snowcover to melt away. Tonight, winds will shift to the northwest as an upper trough and associated cold front push through the area. Behind this cold front, we will see breezy northwest winds on Thursday afternoon (gusts 20-30 MPH). Flurries were added to the forecast for Thursday night as several models are showing some spotty light QPF in response to as secondary trough passage and the upper level jet nosing into the area.
401 PM EST Wed Jan 26 2022 Today has been a variably cloudy and muggy day with the Florida Keys remaining in the warm sector of a dying weak cyclone currently degenerating into a trough over the southeastern Gulf of Mexico. Currently, air temperatures in most Keys island communities are in the upper 70s with dewpoint temperatures in the lower 70s.
707 PM EST Wed Jan 26 2022 Arctic high pressure prompts a burst of cold temperatures through tonight.
Temperatures will get plenty of opportunity to cool before this cloud deck moves in and traps heat, so overnight lows will cool down to the lower 30s again for northeastern counties, mid 40s for the coast, and near 40 everywhere else. Tomorrow will be a few degrees warmer with partly cloudy skies and temps in the upper 50s to low 60s. Increased cloudiness and moisture tomorrow night means temps will dip down into the mid 40s for areas south of I-10 and in the lower 40s elsewhere.
