423 PM MST Mon Jan 3 2022 Low amplitude ridging across the region is bringing quiet weather to the area today. A strong cold front will push through tomorrow, bringing much colder temperatures and gusty NW winds. The best chance is where the High Wind Watch is currently out for.
427 PM MST Mon Jan 3 2022 A broad ridge is currently sliding across the region ahead of the next system making landfall in BC and the Pacific Northwest. Warm- air advection is underway in the southwest flow aloft, which is being felt in the higher elevations. Strong inversions still exist in the lower snow-covered valleys so highs will struggle. The Pac Northwest trough will quickly dive southeastward over the Northern Rockies late tonight. Clouds associated with the increasing moisture will spread across most of the forecast area tonight so lows will be warmer than previous nights. This trough is expected to clip north central CO with the bulk of the forcing remaining north of the area.
Possible freezing fog development lines up well with the lower highs we saw today than expected (mainly due to snow cover and lingering cloud cover). High pressure at the surface that moved into the area yesterday will eventually push E of the CWFA, which will help winds to become more southerly.
400 PM MST Mon Jan 3 2022 High pressure with dry and mostly clear conditions will be persistent through the week.
Look for showers to linger just north of the I-80 corridor clear through the week as strong westerly flow brings in more moisture and warmer temperatures for the region. Latest guidance still expects winds to reach much higher values as the day progresses thanks to combination of the low-level jet and frontal push still making their way into the region.
642 PM EST Mon Jan 3 2022 Quiet weather will remain in place through the middle of the week with high pressure in control.
Another active period of weather begins later tonight as moisture associated with an U/L trough sweeps across the region. This will be the first of many rounds of precip for the upcoming week as upper- level troughing will remain in place across the Pacific NW.
229 PM MST Mon Jan 3 2022 Low amplitude ridging across the region is bringing quiet weather to the area today. A strong cold front will push through tomorrow, bringing much colder temperatures and gusty NW winds. The best chance is where the High Wind Watch is currently out for.
508 PM CST Mon Jan 3 2022 (This evening through Tuesday) Much warmer temperatures are ongoing across Oklahoma and western north Texas this afternoon with temperatures in the 50s deg F. Given the orientation of the low- level thermal ridge, there should be a northeast to southwest gradient in temperatures. Opted to trend warmer than deterministic NBM guidance given the warm 850 mb temperatures and the veered low-level flow. It wouldn't be surprising if temperatures are even warmer in some locations given some of the guidance (e. Besides the warmer temperatures, breezy south to southwest winds are expected tomorrow afternoon--especially near the I-44 corridor --with a tight surface pressure gradient. Winds may actually be lighter across the west, in close proximity to a trough axis (i.
A little snow is expected to accompany the cold front, and some gusty winds develop behind it.
Expect lows in the low to middle 20s with sunrise wind chill only a few degrees lower. Temperatures will trend warmer.
An area of low pressure will move through South Dakota on Tuesday. Ahead of the low, warmer air (seasonable temps) will remain in place. Behind the low, conditions will quickly deteriorate. As the low winds up Tuesday afternoon and enters Iowa/MN, the pressure gradient will tighten to around 20 mb across the state and H85 temps will plummet from the positive single digits to the negative teens. Arctic air in a 1040mb high will follow on the heels of the low Tuesday night. While the winds start picking up, the caa will also help induce snow showers with the low and the upper trough.
647 PM EST Mon Jan 3 2022 High pressure will build across the region tonight, resulting in significantly colder temperatures. The high will drift overhead Tuesday, maintaining a mostly clear sky with light and variable winds.
Also received reports of patchy fog formation already in fog prone locations, and thus with temperatures below freezing, this will be classified as freezing fog. Previously also updated suite of forecast products to mention patchy freezing fog for low lying fog prone locations, near warm bodies of water, etc. Will be monitoring satellite and surface observation trends concerning freezing fog development as evening hours progress. If it appears freezing fog is becoming more widespread, will look into issuance of a freezing fog advisory.
(This evening through Tuesday) Much warmer temperatures are ongoing across Oklahoma and western north Texas this afternoon with temperatures in the 50s deg F.

631 PM EST Mon Jan 3 2022 High pressure will push east across the region tonight into Tuesday. This will lead to dry conditions and somewhat warmer temperatures on Tuesday.
This should help keep low temperatures relatively warmer, in the mid 20s. Have kept highs in those areas closer to 50 degrees while areas to the southeast should see highs around or into the lower 60s.
Minor impacts due to snow and slick roads can be expected along the I-90 corridor from Lookout Pass to Butte during the evening commute as the cold front moves overhead. Behind the cold front, high resolution models continue to indicate the possibility for snow bands developing over west-central Montana during the overnight hours.
A strong cold front moving through the area late Tuesday afternoon will result in a cooldown for a few days.
350 PM CST Mon Jan 3 2022 The forecast concern in the short term will be high wind potential on Tuesday with the arrival of an arctic cold front Tuesday night. A cold front will then drop southeast during the afternoon. The GFS and NAM bufkit soundings do not support expanding the High Wind Watch area.
Hi-Res models are expected precip to gradually decrease through 00Z as ridging builds from the west. High pressure wl maintain dry weather on Tuesday, but with temperature moderation as flow backs to the west aloft, and southwest in the boundary layer.
A look at water vapor imagery reveals an upper trough pulling off to the east as weak mid level ridging builds in aloft. At the surface, high pressure will move off across the eastern CONUS overnight which will allow for weak onshore flow to resume. However, we could see some low lying locations briefly reach freezing across the Northern Coastal Plains early tomorrow morning. Southerly winds will pick up a bit through the day in response to a low pressure system across the Plains. Continued onshore flow through the day will lead to warmer temps Tuesday night with lows in the mid 40s inland to mid 50s along the coast.
113 PM PST Mon Jan 3 2022 Returning onshore flow will bring cooler days, breezy conditions over the mountains and deserts, and patchy low clouds to temper overnight lows west of the mountains through Tuesday. A weak ridge aloft and offshore flow will return fair, dry, and warmer conditions midweek, with temperatures climbing back above average. Onshore flow increases again to wrap up the week with more clouds, and a return to cooler weather. It will be cool again tonight, but not as cold as last night, with patchy frost still likely well inland, in low, wind-sheltered areas and in the lower deserts.
Winds will turn more to the northwest at GUY later in the afternoon with the approach of a cold front.
The below normal temperatures currently in place will begin to moderate as upper-level ridging moves overhead by mid- week. A weak trough approaches the area late in the week and should knock temperatures down a few degrees. The chilly start to 2022 continued this morning, with lows in the Las Vegas Metro below freezing for the 2nd consecutive day. However, temperatures were a couple degrees warmer than yesterday.
225 PM MST Mon Jan 3 2022 A broad ridge is currently sliding across the region ahead of the next system making landfall in BC and the Pacific Northwest. Warm- air advection is underway in the southwest flow aloft, which is being felt in the higher elevations. Strong inversions still exist in the lower snow-covered valleys so highs will struggle. The Pac Northwest trough will quickly dive southeastward over the Northern Rockies late tonight. Clouds associated with the increasing moisture will spread across most of the forecast area tonight so lows will be warmer than previous nights. This trough is expected to clip north central CO with the bulk of the forcing remaining north of the area.
345 PM CST Mon Jan 3 2022 (Issued 345 PM CST Mon Jan 3 2022) Tonight through Tuesday: Gusty south to southwesterly winds will continue tonight into Tuesday ahead of an approaching low pressure system. Despite the clear skies overnight tonight, the warm air advection should be enough to keep temperatures in the low to mid teens. As the low pressure system approaches from the northwest the pressure gradient will tighten causing the southwesterly winds to increase throughout the day. This will lead to day time highs in the low 30s and some increasing cloud cover.
607 PM CST Mon Jan 3 2022 The forecast concern in the short term will be high wind potential on Tuesday with the arrival of an arctic cold front Tuesday night. A cold front will then drop southeast during the afternoon. The GFS and NAM bufkit soundings do not support expanding the High Wind Watch area.
904 PM EST Mon Jan 3 2022 High pressure will push east across the region tonight into Tuesday. This will lead to dry conditions and somewhat warmer temperatures on Tuesday.
Tonight, a cold front moving southward from Canada will begin to shift winds in a more northerly direction, combined with a Pacific front moving from the east, will result in some snow showers moving eastward across the region.
651 PM EST Mon Jan 3 2022 Low pressure has moved away from the area with clear skies and light winds expected overnight.
Building high pressure will clear a band of clouds, oriented north/south over western PA, in the next few hours. With clearing sky and light wind at the sfc, strong radiational cooling will persist into the early morning hours and temps will drop and stay in the low 20s. High pressure wl maintain dry weather on Tuesday, but with temperature moderation as flow backs to the west aloft, and southwest in the boundary layer.
The winds pick up as a developing low pressure system approaches the Great Lakes from the High Plains.
Rain and snow chances return with a Wednesday cold front.
Warm front creeping eastward across western South Dakota, with arctic front accelerating southward across central Montana.
The main impact in the short term will be black ice on secondary roads, bridges, and overpasses that have not completely dried after yesterday's snow. Low level high pressure over the Southern and Central Appalachian region this morning will be shifting east toward the Atlantic coast through the day, while aloft, we will have a generally zonal flow. Tonight, high clouds will increase ahead of an approaching upper trough/jet, and the low level southerly flow will strengthen.
1030 PM EST Mon Jan 3 2022 High pressure continues to build over the local area, bringing with it mostly dry conditions behind a cold front that passed through east central Florida last night and into this morning. Tonight's low temperatures will be cooler than they have been, with lows around average for this time of year.
1054 PM CST Mon Jan 3 2022 (This evening through Tuesday) Much warmer temperatures are ongoing across Oklahoma and western north Texas this afternoon with temperatures in the 50s deg F. Given the orientation of the low- level thermal ridge, there should be a northeast to southwest gradient in temperatures. Opted to trend warmer than deterministic NBM guidance given the warm 850 mb temperatures and the veered low-level flow. It wouldn't be surprising if temperatures are even warmer in some locations given some of the guidance (e. Besides the warmer temperatures, breezy south to southwest winds are expected tomorrow afternoon--especially near the I-44 corridor --with a tight surface pressure gradient. Winds may actually be lighter across the west, in close proximity to a trough axis (i.
Expect this clearing to allow temperatures to fall to dewpoint values and eventually some patchy freezing fog to develop near the I-65 corridor after midnight and increase in coverage a bit towards daybreak, as winds may become a tad lighter. This clearing and lighter winds after midnight (especially near the I-65 corridor) will allow temperatures to fall into the lower 20s in most locations. This should keep lows there in the mid 20s and freezing fog at bay, despite some clearing late. High pressure at the surface that moved into the area yesterday will eventually push E of the CWFA, which will help winds to become more southerly.
1059 PM EST Mon Jan 3 2022 Upper level ridging will build over the eastern seaboard Tuesday and Wednesday. A moisture-starved cold front will push through the region Wednesday night.
Lows tonight will be warmer than what we saw this morning due to southerly flow continuing overnight. Went closer to MOS guidance for lows- especially along the I-10 corridor and the northwest Hill Country- where lows will dip into the lower to mid 20s.
Warm advection was in progress in the lower troposphere as of midnight, with temperatures climbing at 850 mb. A dry cold front will push rapidly through SW KS tonight, with northwest winds in the evening trending north. Wednesday will be noticeably cooler, especially northeast zones that will be deeper in this initial cool airmass. Pressure falls are expected over eastern Colorado in the afternoon, ahead of the incoming, much stronger, arctic cold front. Northeast zones are expected to remain below freezing daylight Wednesday, while south winds warm southwest zones through the 40s.
1048 PM EST Mon Jan 3 2022 As the winter storm departs, chilly high pressure will build into the region through Tuesday followed by a moderating southerly flow of air on Wednesday.
901 PM CST Mon Jan 3 2022 After a brief and modest warm-up on Tuesday, a cold frontal passage early Wednesday morning will bring strong westerly winds and nearly steady temperatures during the day before a sharp cool-down occurs on Wednesday night.
325 AM EST Tue Jan 4 2022 Early morning water vapor satellite imagery is showing a rather dry airmass spread out across the Florida Peninsula in the wake of the recent cold front that has now passed south of Florida.
/Tonight/ The evening sfc analysis indicates sfc ridging anchored from the Middle TN valley SW into SE TX. Thus, winds near the ridge axis have decoupled since the setting sun, with temps quickly plummeting below freezing as of mid-evening across much of the region given the very dry, arctic air mass in place.
At the surface, high pressure gradually shifts east of the area shifting us from northerly surface flow tonight to more easterly and ultimately southerly by Tuesday afternoon and evening. Many locations are already down to or near the freezing mark, and expect temperatures to generally fall into the middle to upper 20's for most locations. Highs will be warmer Tuesday for most of the area, rising into the middle to perhaps upper 50's. Lows Tuesday night are cool once again but much warmer compared to the previous night. Wednesday features even warmer weather, with highs in the lower to middle 60's.
1019 PM EST Mon Jan 3 2022 Cool high pressure will build into the area and persist through the middle part of the week. Another cold front could impact the area late this week. Strong and cold high pressure will build out of West Virginia and Virginia through the night, leading to clear skies across the forecast area. We have min temps ranging from the upper 20s along the northwest tier to the lower and middle 30s most elsewhere. Thus, we expect a return to fair, cooler and less humid conditions. Some semblance of a coastal trough does develop well offshore Tuesday, slowly migrating toward the coast Tuesday night into Wednesday. This will eventually drive the tail-end of a cold front into the SE states toward the latter half of the week.
/issued 936 PM CST Mon Jan 3 2022/ High pressure continues to settle over the Mid-South this evening. With temperatures below freezing, it would be freezing fog. Will add mention of freezing fog to grids. Expect lows in the low to middle 20s with sunrise wind chill only a few degrees lower. Temperatures will trend warmer. Everyone should be above freezing Wednesday morning with highs in the mid 40s to mid 50s. Northwest flow will return to the area Wednesday allowing another strong cold front to move across the region.
A broad ridge is currently sliding across the region ahead of the next system making landfall in BC and the Pacific Northwest. Warm- air advection is underway in the southwest flow aloft, which is being felt in the higher elevations. Strong inversions still exist in the lower snow-covered valleys so highs will struggle. The Pac Northwest trough will quickly dive southeastward over the Northern Rockies late tonight. Clouds associated with the increasing moisture will spread across most of the forecast area tonight so lows will be warmer than previous nights. This trough is expected to clip north central CO with the bulk of the forcing remaining north of the area.
258 AM CST Tue Jan 4 2022 Key Messages: - Warm temperatures and breezy southerly winds are expected today, followed by a cold front this evening with gusty northwest winds.
North- central WI and cooler central WI locales may fall into the single digits to even around zero, however. Mid/high clouds will increase on Tuesday ahead of the trough with highs reaching the mid 20s to low 30s. Majority of guidance shows this system morphing into a closed low over the Great Lakes region early Wednesday. Some hints of transient low-level frontogenetic support coming into play Tuesday night as the cold front swings through locally, but nothing for any appreciable length of time to support localized banding. some patchy light initial freezing drizzle. Regardless, freezing drizzle threat (if any) currently looks very marginal and limited in area.
This process will trail a strong cold front through Wednesday morning with flurries/snow showers, falling temps and gusty winds (sub zero wind chills possible by late Wed-Wed night).
245 AM EST Tue Jan 4 2022 Dry and warmer days through Wednesday.
Another strong cold front will move through the area Tuesday night into early Wednesday.
1243 AM EST Tue Jan 4 2022 Cool high pressure will build into the area and persist through the middle part of the week. Another cold front could impact the area late this week. Thus, we expect a return to fair, cooler and less humid conditions. Some semblance of a coastal trough does develop well offshore Tuesday, slowly migrating toward the coast Tuesday night into Wednesday. This will eventually drive the tail-end of a cold front into the SE states toward the latter half of the week.
1242 AM EST Tue Jan 4 2022 As the winter storm departs, chilly high pressure will build into the region through Tuesday followed by a moderating southerly flow of air on Wednesday.
1022 PM EST Mon Jan 3 2022 Upper level ridging will build over the eastern seaboard Tuesday and Wednesday. A moisture-starved cold front will push through the region Wednesday night.
At the surface, a lee trough extends down the High Plains, with a ridge axis extending from the northwest Gulf up into the Ohio Valley.
Otherwise, building high pressure will clear a band of clouds, oriented north/south over western PA, in the next few hours. High pressure wl maintain dry weather on Tuesday, but with temperature moderation as flow backs to the west aloft, and southwest in the boundary layer.
A cold front will push south across the TAF sites during the late afternoon into the early evening hours. Winds will turn more to the northwest at GUY later in the afternoon with the approach of a cold front.
936 PM CST Mon Jan 3 2022 High pressure continues to settle over the Mid-South this evening. With temperatures below freezing, it would be freezing fog. Will add mention of freezing fog to grids. Expect lows in the low to middle 20s with sunrise wind chill only a few degrees lower. Temperatures will trend warmer. Everyone should be above freezing Wednesday morning with highs in the mid 40s to mid 50s. Northwest flow will return to the area Wednesday allowing another strong cold front to move across the region.
1125 PM CST Mon Jan 3 2022 After a brief and modest warm-up on Tuesday, a cold frontal passage early Wednesday morning will bring strong westerly winds and nearly steady temperatures during the day before a sharp cool-down occurs on Wednesday night.
Clouds will increase as zonal mid-level flow becomes WSW in base of very broad large upper trough that extends across the entire CONUS by 00Z Wed.
The approach of the low will make for breezy sswly winds and warm advection Tue-Tue eve. The strong cold front and brisk wly winds will then arrive late Tue nt and Wed AM. Gehring (Issued 345 PM CST Mon Jan 3 2022) Tonight through Tuesday: Gusty south to southwesterly winds will continue tonight into Tuesday ahead of an approaching low pressure system. Despite the clear skies overnight tonight, the warm air advection should be enough to keep temperatures in the low to mid teens. As the low pressure system approaches from the northwest the pressure gradient will tighten causing the southwesterly winds to increase throughout the day. This will lead to day time highs in the low 30s and some increasing cloud cover.
1210 AM EST Tue Jan 4 2022 High pressure will push east across the region tonight into Tuesday. This will lead to dry conditions and somewhat warmer temperatures on Tuesday.
1205 AM EST Tue Jan 4 2022 Cold high pressure will be overhead today and early tonight before moving offshore overnight.
1000 PM MST Mon Jan 3 2022 High pressure with dry and mostly clear conditions will be persistent through the week. Localized freezing temperatures will again be possible Wednesday morning, but mainly away from population centers.
(Today and tonight) With sunny skies today, temperatures will be warmer. This will occur as low pressure develops across the Texas Panhandle toward Childress, and surface pressure gradient increases across our area.
221 AM CST Tue Jan 4 2022 A strong upper jet maximum will continue to drive an upper trof from the northern Rockies across the northern Plains today. Stronger southerly low level flow ahead of the lee side trof will result in gusty winds this morning. As this trof moves eastward toward central Kansas by early afternoon, the strongest gusts will affect the Flint Hills and southeast Kansas, though expected to remain just below wind advisory criteria. Otherwise, temperatures will continue to warm a bit over yesterday with highs in the 50s, less a few degrees cooler over the residual snow cover in central Kansas. The approaching upper trof will amplify as it moves over the Upper Midwest and western Great Lakes tonight into Wednesday with a shallow cold front dropping temperatures back below climo.
This will lead to a quick veering of the winds by the afternoon which should allow temperatures across the southwestern South Plains to warm to near 60 degrees while the rest of the area remains in the low to mid 50's.
