355 AM PST Tue Feb 8 2022 High pressure will rebound Tuesday bringing a prolonged period of mild and dry weather with areas of morning low clouds and fog. Tuesday and Wednesday: Quiet weather is expected over the next several days as a strong ridge of high pressure moves inland with a northwest flow aloft. Current satellite imagery shows high level clouds moving into the Inland Northwest as systems pass over the ridge into British Columbia. The warmer temperatures and breezy winds from today have kept fog almost nonexistent across the northern and central valleys. Temperatures today will be cooler compared to yesterday with highs in the upper 30s to mid 40s (low 50s in the L-C Valley today and tomorrow). The region will see slight warming on Wednesday with highs in the low to upper 40s.
828 AM CST Tue Feb 8 2022 After a cold start in the lower to middle 20s, temperatures are rising into the 30s. After the low level inversion mixes out, temperatures should warm nicely into the lower 50s by midday on their way to highs in the middle 50s for valley locations and upper 40s to around 50 atop the higher plateaus. The ridge of high pressure now across the OH, TN and lower MS valley will shift southeast a bit today, allowing southwest flow to develop in our northwestern counties this afternoon. The clear sky and dry air mass in place will allow for good radiational cooling this evening, with temperatures eventually settling in the lower 30s by early Wednesday morning.
521 AM CST Tue Feb 8 2022 (Today) SSW winds ahead of a weak cold front along with generally clear skies will result in a substantial warm up this afternoon, with very little lingering impact of snow cover remaining.
208 PM EST Tue Feb 8 2022 High pressure will build overhead tonight, then shift offshore Wednesday.
(This afternoon through Wednesday night) The quiescent pattern will continue over the next 36 hours beneath dry northwesterly flow aloft, with a weak cold front progged to move through the region tonight and Wednesday morning. High temperatures on Wednesday will be in the 60s across lower elevations with 50s across the higher terrain, similar to today despite the aforementioned cold front, thanks to a return to southerly/southeasterly surface flow by afternoon.
High pressure continues to dominate across the region this morning/afternoon as the upper trough axis shifts overhead. VFR prevailing conditions are forecast throughout the TAF period with clear skies and light winds as high pressure builds in from the west.

1024 AM EST Tue Feb 8 2022 Low pressure moves along our coast today and tonight. High pressure builds back over the area from the west late Tuesday through late week. The area of low pressure that brought us rainy weather yesterday is now well to our northeast and will continue moving farther away from the area this morning. Between 9 AM and noon, a dry cold front now just northwest of Raleigh, will help break up the inversion and our skies will brighten quite a bit as the low clouds scour out. High pressure builds across Eastern North Carolina tonight.
Gusty north winds in the wake of the front this evening will subside overnight as high pressure settles over the region. /DWK Upper level ridging will remain in place across the western CONUS through the weekend.
925-850 mb thermal trough with mean min temps around -10C and some values around 14C (favorable for dendritic growth) was located over the Alleghenies and Laurel Highlands at midday and will continue to produce fairly steady light snow across the region near and to the west of RT 219, with occasional snow showers and flurries near the I-99/RT 220 corridor. Mainly clear to partly cloudy skies will follow for tonight with the departure of the low-mid level trough, and an area of high pressure ridging across the CWA.
Gusty westerly winds this afternoon will become northerly by early this evening with the passage of a cold front. A strong upper ridge along the west coast keeps the jet stream orientation northwest to southeast producing a series of very quick moving cold fronts.
high temps are expected to be several degrees warmer with highs in the mid 50s - mid 60s common. Any lingering impact from snow cover looks to be confined to mainly the higher terrain of far Northwest Arkansas.
827 AM MST Tue Feb 8 2022 Low pressure system continues to advect east across the plains today. Lows tonight will drop to around freezing. locally higher amounts across the highest elevations.
Lows tonight should be above freezing area wide. A weak and dry cold front will pass through the area tonight resulting in slightly cooler conditions tomorrow.
Currently, temperatures across Upper Michigan are generally in the low to mid 30s with some upper 20s over the far eastern counties. Normal high temperatures for this time of year are closer to the low 20s.
SHORT TERM (Now through Wednesday Night): High pressure builds across Deep South Texas with light winds and generally clear skies.
236 PM CST Tue Feb 8 2022 High pressure centered over the western Gulf of Mexico into the Appalachian mountains hold tight tonight from the western Gulf of Mexico into the Appalachian mountains. This area of high pressure will slowly weaken on Wednesday.
The Lower and Upper Keys are in the lower to mid 70s while the Middle Keys are in the mid to upper 70s. Visible satellite shows a mid deck of altocu associated with convection in the southwest Straits of Florida, moving northeast towards the Lower Keys. This deck should stay just north of the Lower Keys and dissipate over the next couple of hours. This front has temporarily stalled as we await a high pressure to move out of the Southern Plains to help push it further along. Breezes will begin freshening this afternoon and peak this evening as a weak cold front sweeps through. This front will be preceded by high pressure, maintaining moderate to fresh breezes for Wedneday.
1222 PM EST Tue Feb 8 2022 High pressure allows for dry weather tonight. A moisture starved cold front arrives Wednesday. Chances for rain with another cold front this weekend. A high pressure system will provide dry weather tonight. A moisture starved cold front will then push through on Wednesday. Will continue with dry weather and warmer Wednesday with temperatures reaching the mid 50s lowlands.
Otherwise, forecast remains on track with high pressure bringing continued dry conditions and light wind.
/EC/ Prior discussion below: Today and Tonight: A weak midlevel trough with an axis centered over the ArkLaMiss region will continue cool and dry conditions throughout the remainder of the short term period. By this evening, the trough axis should remain east of MS, which will allow for sustained light W/SW winds into the overnight period. Low temperatures will bottom out in the lower to mid 30s overnight. Broad mid-level troughing will remain present across the region.
There is an upper level low over southern Canada and a series of short waves moving through the northern plains. Tonight and overnight the low over southern Canada will advance towards the upper great lakes region, while a cold front associated with the system will slowly advance to the mid west by Wednesday morning. Overnight lows will generally be in the lower 30s, but some of the deeper valleys may fall into the upper 20s. Partly cloudy and warm ahead of the front, with afternoon high temps in the low to middle 50s.
Above-normal temperatures are the highlight of the forecast this week as most locations warm into the 60's and 70's.
209 PM EST Tue Feb 8 2022 High pressure builds in tonight through Wednesday.
A weak cold front will move through this evening with little overall change in the weather.
Some cloud cover moves into the area overnight into tomorrow as a cold front passes west to east across the region on Wednesday afternoon into evening.
After a cold start in the lower to middle 20s, temperatures are rising into the 30s. After the low level inversion mixes out, temperatures should warm nicely into the lower 50s by midday on their way to highs in the middle 50s for valley locations and upper 40s to around 50 atop the higher plateaus. The ridge of high pressure now across the OH, TN and lower MS valley will shift southeast a bit today, allowing southwest flow to develop in our northwestern counties this afternoon. The clear sky and dry air mass in place will allow for good radiational cooling this evening, with temperatures eventually settling in the lower 30s by early Wednesday morning.
1253 PM EST Tue Feb 8 2022 Low pressure moves along our coast today and tonight. High pressure builds back over the area from the west late Tuesday through late week. The area of low pressure that brought us rainy weather yesterday is now well to our northeast and will continue moving farther away from the area this morning. Between 9 AM and noon, a dry cold front now just northwest of Raleigh, will help break up the inversion and our skies will brighten quite a bit as the low clouds scour out. High pressure builds across Eastern North Carolina tonight.
159 PM MST Tue Feb 8 2022 Highs will peak a few degrees cooler today behind a cold front that pushed through this morning. Most locations will still be well above normal for this time of year as the ridging continues across the western US.
The main trough axis remains situated over the Dakotas early this afternoon. Model soundings at EST/MCW show periods of low level saturation through the lowest kilometer with drier air aloft including through the dendritic growth zone. As such, light freezing drizzle is the primary precipitation type for tonight should precipitation develop.
100 PM EST Tue Feb 8 2022 High pressure builds in tonight through Wednesday.
1228 PM EST Tue Feb 8 2022 Dry weather is expected today as high pressure builds to the south.
Heights will rise through the afternoon and stable conditions will continue with clear skies as ridging briefly builds into the area. An upper low will track across Ontario tomorrow and provide weak cyclonic curvature and height falls over the Southeast. The air will be dry enough such that PoPs will remain at 0 percent, but the prevailing westerly flow will help to provide the warmer air.
139 PM MST Tue Feb 8 2022 High pressure will bring dry conditions with a warming trend the rest of the week.
This front will also initially have stronger winds along the leading edge of the front and expecting breezy conditions to develop across the Lower Keys tonight.
With high pressure off to the west and a longwave trough across the central plains, expect persistent northeast flow, dry conditions, and above average daytime temperatures for north-central Arizona today. High pressure over the Pacific will continue to push to the east over the coming week, keeping us on the east side of the mid level ridge.
A strong ridge over the eastern Pacific will remain there for the remainder of this week.
331 PM EST Tue Feb 8 2022 Dry, tranquil conditions with decreasing clouds will occur late today through Wednesday morning as a ridge of high pressure builds over the state.
High pressure continues to dominate across the region this morning/afternoon as the upper trough axis shifts overhead. VFR through the period as high pressure prevails at all terminals.

356 PM EST Tue Feb 8 2022 High pressure builds over the area through late week. Winds expected to decouple as high pressure gains a stronger footing across the FA. Lows tonight will be in the low 30s inland with mid to upper 30s closer to the coast. High pressure will remain in control with a dry forecast on tap. Low level thickness values look to support warmer temperatures for the aftn, but most areas inland are expected to remain just shy of 60. OBX coast will see a weak NNE flow that will keep them stuck in the low to mid 50s.
Ridging aloft will keep dry conditions in place through tonight. An upper level trough will move across the region Wednesday. The airmass will modify with temperatures on Wednesday a little warmer than today and closer to normal values. Increasing cloud cover and a light south to southeast wind (at times variable) developing by Wednesday night will lead to slightly warmer lows, but still below normal values for this time of year.
Inversion conditions will continue through Wednesday with warmer temperatures at high elevations.
/GKoch 18Z TAFS: The passage of yesterday's dry front scoured out most of the low clouds and fog from the Inland Northwest. Looking at the High Resolution Ensemble (HREF), the majority of our short range guidance is dry for our TAF sites.
Low pressure will move across south FL this evening, and to the east of the area Overnight into early Wednesday. As the low moves further to the northeast Wednesday, high pressure will build from the west and northwest. As the high builds Tonight, skies will begin to clear well inland, with clearing across forecast area from northwest to southeast through the day Wednesday. With expected sunshine, temperatures will recover into the lower 60s on Wednesday. The coolest spots Wednesday afternoon will be along the coast, due to northerly flow across the relatively cooler waters.
Could see a few mid to high cigs as a weak cold front moves through the area overnight into Wednesday. Mostly clear skies will continue across the region today, with highs in the low to mid 60s. Afternoon temperatures today will range from the lower to mid 60s across the region with plentiful sunshine. Temperatures will remain above freezing tonight, also the first time for the past few days.
A couple weak ripples in a broader upper trough over the upper Mississippi River valley will descend southeast into the Ark-La-Tex the next couple days before becoming less noticeable at the base of the trough.
254 PM CST Tue Feb 8 2022 A 995mb occluded low pressure system across southwestern Ontario has resulted in a tight pressure gradient across the region, and thus breezy to windy conditions this afternoon. Temperatures will be cooler Wednesday, due to continued weak CAA and cloud cover, though highs will still be near to around 10 degrees above average (in the upper 20s to mid 40s). The grassland fire danger will be lower due to the higher relative humidities, but still high considering northwest wind gusts of around 30 knots during the afternoon. North to northwest flow will continue aloft, with a nearly steady- state broad 500mb trough residing over eastern Canada through the eastern two thirds of the U.
A weak cold front will slide across the are abut have little effect. Lows tonight will still be mainly a radiational cooling situation, with the usual cold air drainage areas seeing the lowest temperatures. The area will remain under dry northwest flow aloft through the end of the workweek as strong upper level ridging dominates over the western US.
Temperatures continue to warm into the upper 50's to near 60 degrees today for most locations, with even warmer temps in the middle 60's expected Wednesday. We have another cold night on tap tonight with lows in the lower 30's for most locations.
The coolest nights will be Tuesday and Wednesday night with lows in the upper 30's to mid 40's possible, however no freezing temperatures or frost is expected. The rainfall will be slow to exit the area, but should begin to clear out by late morning on Wednesday as high pressure builds into the southeast U.
237 PM CST Tue Feb 8 2022 18z data has a weak low east of KMSP with a warm front running through southwest Wisconsin and northern Illinois. A cold front ran from the low southwest into the Oklahoma panhandle. The next clipper system passes well north of the area but the attendant cold front will sweep through this afternoon/evening with only an increase in clouds.
Clouds increase with the trough tonight, with a period of light precip possible from late tonight through much of the day on Wednesday. Overall, think that light snow showers will be the predominate precip type, but some light rain or freezing rain/drizzle (depending on surface temperature) may mix in at times. In any case, actual QPF will be very light, so outside of a few slick spots during the morning when temperatures will be below freezing, impacts should be minimal.
Ridge of high pressure anchored over the West Coast will keep conditions dry and warm across much of the region this week, with periodic northerly breezes. Forecast looks to be on track with an upper-level ridge dominating the sensible weather this week. Ridging over the west coast will be the dominant feature through the end of the week and into the weekend. This ridging will allow for temperatures to warm up to well above normal for this time of year.
VFR conditions are expected to prevail through the TAF period with high pressure in control. High pressure building into the Lone Star State will produce VFR conditions at the aerodromes through the next 24 hours.
1234 PM PST Tue Feb 8 2022 A strong ridge remains locked over the eastern Pacific, continuing our dry and mild conditions. The static pattern of high pressure dominance lingers well into the early days of February. Low pressure systems that advance across the Pacific have done little to degrade the ridge, so influences from these waves are limited to increasing winds in the near term. Warmer daytime highs are on tap for the weekend, with temperatures reaching mid- to upper-60s in valleys and 50s elsewhere. Our impacts are largely dependent on the position and strength of the system, and how/where the low tracks around the ridge.
Many of the higher resolution models are suggesting a band of light precipitation along the weak front associated with the larger system, and this is borne out by weak returns on national radar mosaic at this time.
The combination of cyclonic flow through a deep vertical layer, steepening low-level lapse rates (from CAA maximized around 700 hPa), and marginal low-level moisture could also be sufficient to yield isolated rain showers across east- central and south-central IL with weak low-level convergence along the cold front during the late afternoon/evening. Behind the first front, temps at 850-hPa will cool 7 to 10 C between today and Wednesday, but with surface winds and low-level flow predominantly westerly ahead of the second cold front high temps will again be above average and only up to 10 F cooler (in the low-40s to mid-50s F).
212 PM CST Tue Feb 8 2022 Dry weather continues to roll on the next few days but a decent cold front is coming in over the weekend which may give us some light pcpn. Early Sat, a fairly strong cold front will push through the mid- state, but upper support really not that great.
Mostly clear skies will continue across the region today, with highs in the low to mid 60s. Afternoon temperatures today will range from the lower to mid 60s across the region with plentiful sunshine. Temperatures will remain above freezing tonight, also the first time for the past few days.
142 PM EST Tue Feb 8 2022 High pressure allows for dry weather tonight. A moisture starved cold front arrives Wednesday.
Could see some temps around the freezing mark in areas north of the Interstate 30 corridor, especially across portions of Southeast Oklahoma and adjacent Southwest Arkansas.
A longwave trough will clear the Southeast US tonight while a secondary trough swings through the Southeast on Wednesday. Lows will drop into the lower to middle 30s for most of the area, but may remain in the upper 30s in the southeast Big Bend (where clouds will be the slowest to clear). Sunshine (finally) returns again on Wednesday, and temperatures will respond by rising into the lower to middle 60s.
1038 AM MST Tue Feb 8 2022 Low pressure system continues to advect east across the plains today. Lows tonight will drop to around freezing. locally higher amounts across the highest elevations.
Highs today will be near season normals, in the low to mid 60s. A weak cold front will move into the Big Country late this evening, then through the rest of the area Wednesday morning. The area will remain under dry northwest flow aloft through the end of the workweek as strong upper level ridging dominates over the western US.
Lingering flurries will end quickly this afternoon with passage of the light-snow-supporting trough axis. That warm advection will drive high temperature 5 to 10 degrees above avg on Wednesday, but the approach and passage of the aforementioned trough will promote light rain and snow development for late Wednesday aftn and night.
1112 AM CST Tue Feb 8 2022 VFR conditions will persist today through Wednesday with high pressure maintaining dry conditions across the area.
347 PM EST Tue Feb 8 2022 High pressure begins to shift eastward but keeps conditions dry through Wednesday night.
Latest synoptic analysis indicates the center of a broad area of high pressure located over the South Central CONUS, nearly directly over SE TX. Light winds and clear skies have paved the way for a gorgeous afternoon, with daytime highs thus far topping out in the low to mid 60s area wide. Have once again incorporated the lower end of NBM distribution for low temps given blend performance over the past few days, clear skies, and relatively unchanged synoptic pattern.
157 PM MST Tue Feb 8 2022 Sunny skies have prevailed across much of eastern Utah and western Colorado today as dry northwesterly flow dominates overhead in response to the continued building of the west coast ridge. This system will quickly exit to the east late this afternoon as the high's center continues to wobble off the coast of northern California.
Issued by National Weather Service Jackson KY 1051 AM EST Tue Feb 8 2022 Dry weather is expected today as high pressure builds to the south.
High temperatures will be similar to those today, in the 40s and lower 50s across the plains and 20s and lower 30s in the high country.
623 PM EST Tue Feb 8 2022 High pressure builds in tonight through Wednesday.
Several impulses will ride the eastern side of the western NOAM ridge wavering a sfc front and supporting bouts of rain and snow showers. Strong upper trough continues to advance SE across the region with the FA under the dry slot. Have canceled the high wind warning, as the strongest winds aloft have shifted SE, opting for a wind adv for the remainder of the afternoon there.
A weak cold front is moving across the region this afternoon. While the cold front that is moving through today will knock temperatures down ever so slightly, continued westerly flow over the down sloped warmed air of the western Plains will push temperatures into the high 40s to around 50 the next couple of days. A trough deepens across the upper midwest which turns 850 mb flow out of the SW. The large areal expanse and velocity of the LLJ shuttles warmer air into the area as it feeds the deepening cyclone.
Clear skies with VFR conditions will continue to prevail through the TAF period as high pressure remains in control. /issued 255 PM CST Tue Feb 8 2022/ SHORT TERM (Now through Wednesday Night): High pressure builds across Deep South Texas with light winds and generally clear skies.
430 PM MST Tue Feb 8 2022 Highs will peak a few degrees cooler today behind a cold front that pushed through this morning. Most locations will still be well above normal for this time of year as the ridging continues across the western US.
Dry weather continues to roll on the next few days but a decent cold front is coming in over the weekend which may give us some light pcpn. Early Sat, a fairly strong cold front will push through the mid- state, but upper support really not that great.
High pressure will remain anchored over the area through the weekend which will keep weather quiet for the next several days.
