630 AM EST Sat Jan 22 2022 High pressure with some bitterly cold air will be over the region through today. A deep upper level trough is setting up over the northeastern CONUS, resulting in a prolonged cold spell with below normal temperatures certain.
326 AM MST Sat Jan 22 2022 A storm system will bring increasing clouds, scattered showers, gusty winds and cooler temperatures this weekend. Broad troughiness has opened up across most of the CONUS, with our area on the back side in the northerly flow. Our area will see the best chance of showers later today or tonight in an initial weak convective band opening up on the eastern flank of the low, and then again Sunday as the low itself pushes through.
The splitting upper level trough responsible for yesterday's light snowfall has transitioned to a closed low over southwest Arizona while the northern wave has continued to progress east towards the Northern Plains. Additional light snow showers have lingered over some of the higher elevations across southwest Colorado but, for the most part, denser clouds have started to dissipate across the region as this system continues to sag south. Bufkit soundings show this low stratus will persist through the early to mid morning hours. Pattern-wise, eastern Utah and western Colorado will remain sandwiched in between an elongating trough of low pressure over the central states and an amplifying ridge off the west coast while the aforementioned closed low slowly hovers near Baja.
Patchy freezing fog across areas of northern and central Nevada will diminish early this morning. Today through Sunday Patchy freezing fog across northern and central Nevada will diminish this morning.
There's some patchy fog across Middle Park early this morning, and patchy fog is also possible for the next few hours over North Park and the lower elevations of Weld county. Any remaining low clouds/patchy fog should burn out this morning as temperatures rebound into the low to mid 40s across the plains. Lows tonight will be in the teens to 20s across the plains and foothills with single digits likely for the higher terrain. Dry NW flow aloft will be across the area on Sun as a sfc lee trough develops. This will allow for warmer temps, across nern CO, with aftn highs ranging from the upper 40s to mid 50s. Highs will drop back into the lower to mid 30s over nern CO. By Thu into Fri, an upper level ridge is fcst to build into the area.
A ridge over the region will be the dominate feature through the week. The ridge axis, or the center of the ridge, will be west of the region setting up northwest flow. These do have the potential to cause some light precipitation, mainly in western Montana, but it will be subdued by the ridge's influence.
The first wave today will move a warm front to the east and bring a chance of light snow mixed at times with light rain to the northeast half of the forecast area.
456 AM CST Sat Jan 22 2022 Expect VFR conditions to persist through this TAF period as high pressure moves across the state. with lows tonight also warmer in the 20s.
426 AM EST Sat Jan 22 2022 Cold and dry weather continues today under high pressure.
640 AM EST Sat Jan 22 2022 Dry conditions will continue into this evening as high pressure sinks south of the area.
648 AM EST Sat Jan 22 2022 High pressure with some bitterly cold air will be over the region through today. A deep upper level trough is setting up over the northeastern CONUS, resulting in a prolonged cold spell with below normal temperatures certain.
Pattern is in a shifting state of weak ridging ahead of a closed upper-low out over AZ. The closed low will meander today before scooting eastward on Sunday through the end of the forecast period. Limited ascent will be offered prior to Sunday evening, so the only area that might see any precip will the far western zones with an isolated shower or even snow shower in the highest confines of the Guadalupes.
Overall, the relatively stable pattern will continue with a ridge of high pressure offshore that continues to build into our area. This will create a thermal trough/offshore (east) wind pattern typical of fall in the short-term. Mid to upper slopes and ridges will see some gusty east winds, with northeast winds possible in some of our valleys, just like the Chetco river drainage creating extra warm temperatures in Brookings today (low 70s). However, expect the status shield to break up slightly earlier in the afternoon allowing for a little more sunshine and temperatures a few degrees warmer than yesterday. We will still see the ridge, but with the east winds decreasing expect cooler temperatures at Brookings, and air to begin stagnating everywhere with a bit more of a marine push.
712 AM EST Sat Jan 22 2022 Cold and dry weather continues today under high pressure.
Some isolated areas in Sargent, Ransom, and Barnes county may hit the lower teens for highs. Where the main frontogensis sets up will dictate where exactly the higher amounts above an inch fall. Momentum transfers Sunday afternoon look deep and not as strong in the lower levels. 1 peak winds indicate 30 to 40 kts across the higher terrain west of the valley with the valley in the 28 to 35kt range.
Temperatures will rise from the low-mid 40s today to the upper 40s/lower 50s on Sunday.
By this afternoon, winds are expected to increase to 5- 12 mph, and resulting warm air advection will lift temperatures into the low to mid 30s for highs. Tonight, the pressure gradient will remain relatively tight ahead of a cold front dropping south from the northwest. A clipper system drops SE through the parent eastern CONUS troughing on Sunday. Temperatures likely won't make it out of the low to mid 30s in our NE where snow is expected, however look for upper 30s and low 40s elsewhere across our CWA.
Highs will be slightly warmer today in the upper 30s and lower 40s. McD Chattanooga Airport, TN 24 48 27 52 35 / 0 0 0 0 10 Knoxville McGhee Tyson Airport, TN 22 45 26 48 34 / 0 0 0 0 10 Oak Ridge, TN 22 46 24 47 33 / 0 0 0 0 10 Tri Cities Airport, TN 19 41 23 44 29 / 0 0 0 0 0.
1010 AM EST Sat Jan 22 2022 High pressure will provide cold and dry conditions through Sunday morning. A weak cold front should bring snow showers to southeast West Virginia during Sunday afternoon into Sunday night.
243 PM CST Sat Jan 22 2022 At 20Z (2:00 PM CST) this afternoon, temperatures had warmed to near 50 degrees in many locations across the forecast area, making for a noticeably warmer day than recent days. Surface maps showed high pressure centered over the Red River Valley while a clipper system was moving from Canada into the Dakotas. A cooler air mass in the wake of tonight's clipper system will impact temperatures tomorrow, especially in far northeast and eastern KS.
Temperatures will continue to rebound through the day with afternoon highs peaking in the low to upper 40s beneath sunny skies. High pressure building into the region keeping the forecast quiet but cold, with this morning starting off in the upper teens and lower 20s. Weakly northwesterly flow aloft remains through the short term, as a cutoff upper low parks over the desert SW. but warmer than yesterday. Tonight, temps will drop into the low to mid 20s yet again.
103 PM EST Sat Jan 22 2022 High pressure will cross the region today then move east Sunday. A cold front will cross the region later Sunday through Sunday night.
Warmer air to advect north allowing for a gradual warming trend through Sunday night with afternoon highs on Sunday near 60 degrees with overnight lows on Sunday night in the low to mid 30s.
Note the low chance as suggested by guidance is a bit generous, with amounts likely to be very little. Otherwise, as the back edge of the cold frontal zone passes, some partial clearing and freshening of northwest winds can be expected. Some guidance as backed off a bit on the winds Sunday night, however cold advection over the warmer waters should lead to several hours of breezy conditions. High pressure will settle into the northern Gulf of Mexico, allowing winds to quickly decrease and become more easterly early in the work week.
Associated mid level warm front will bring a chance for light snow to the area from west to east tonight, then across central and eastern areas of the state during the day Sunday.
This cloud cover that has helped to keep temperatures cooler than surrounding areas this afternoon, will serve to keep temperatures a bit warmer overnight (mainly for areas south of Interstate 20). The aforementioned cloud cover will again persist across much of the area south of I-20, ahead of an approaching upper level low to our west.
Temperatures tonight will be near average for late January with lows ranging in the low to mid 20s.
/NEW/ /This afternoon through Sunday/ A building ridge aloft and a deep layer of dry air will result in a sunny and warmer day across North and Central Texas with highs generally in the lower and middle 50s. Some subtle changes will begin to take shape on Sunday in response to an approaching upper low from the Desert Southwest. The main changes will be a few more clouds, slightly warmer temperatures and the return of a west to southwest wind. expect afternoon temperatures to climb up into the 60s thanks to the ridging aloft and mostly sunny skies.
312 PM EST Sat Jan 22 2022 A milder westerly flow of air returns to the region tonight as high pressure slides off of the eastern seaboard tonight.
High pressure will keep significant weather systems away from the area for at least the next several days.
VFR conditions will continue through the period as high pressure slides across the area. highs today will range from the lower to mid 50s, then into the mid to upper 50s tomorrow afternoon.
At the surface, high pressure located over southern Kentucky will continue to shift to the east, allowing warmer southwesterly surface flow to continue through this afternoon and into Sunday morning. Low temperatures tonight will be much warmer than Sunday morning's values, only dropping into the middle and upper 20s at most locations. However, as CAA and gusty NW winds arrive from an associated cold front, temperatures will begin to fall during the afternoon, especially in our northern counties.
1051 AM EST Sat Jan 22 2022 High pressure will cross the region today then move east Sunday. A cold front will cross the region later Sunday through Sunday night.
/Issued 1100 AM CST Sat Jan 22 2022/ /This afternoon through Sunday/ A building ridge aloft and a deep layer of dry air will result in a sunny and warmer day across North and Central Texas with highs generally in the lower and middle 50s. Some subtle changes will begin to take shape on Sunday in response to an approaching upper low from the Desert Southwest. The main changes will be a few more clouds, slightly warmer temperatures and the return of a west to southwest wind.
257 PM EST Sat Jan 22 2022 The cold front is currently pushing through the southern most zones this afternoon, with light areas of rain in place across the CWA along with overcast low clouds. The rain and clouds will be slowly clearing out of the area overnight from north to south as cooler and drier high pressure starts to build into the area from the NW.
1027 AM MST Sat Jan 22 2022 18Z TAF CYCLE Upper low centered over swrn/south central AZ at 17Z advecting mid and lower level moisture into west central NM as well as up the lower and middle RGV, which may contain isold light showers, while ely low level flow into central and ern NM slowly weakens.

1118 AM CST Sat Jan 22 2022 (The rest of today ) A mostly sunny and warmer day is in progress across eastern Oklahoma and northwest Arkansas.
The cloud cover should keep temperatures warmer tonight compared to last night.
1255 PM EST Sat Jan 22 2022 Dry conditions will continue into this evening as high pressure sinks south of the area.
With thicknesses increasing just a hair tomorrow combined with light westerly winds, afternoon high temperatures should be about 5 degrees warmer than today.
Warmer tomorrow with highs in the 40s. In the upper levels, a trough will be over the Eastern U. At the surface, high pressure will be over the Southeast as a low moves through the Midwest. Lows will be in the lower 20s for most locations. Tomorrow will be dry and warmer as southerly low level flow returns to the region. Highs will be in the low to mid 40s which is still slightly below normal for this time of year.
Only other tweak to the forecast is the high temps for this afternoon. Else where, temps should rise into the low 30s, possibly just above freezing in a few spots. By this afternoon, winds are expected to increase to 5- 12 mph, and resulting warm air advection will lift temperatures into the low to mid 30s for highs. Tonight, the pressure gradient will remain relatively tight ahead of a cold front dropping south from the northwest. A clipper system drops SE through the parent eastern CONUS troughing on Sunday. Temperatures likely won't make it out of the low to mid 30s in our NE where snow is expected, however look for upper 30s and low 40s elsewhere across our CWA.
1021 AM EST Sat Jan 22 2022 High pressure with some bitterly cold air will be over the region through today. A deep upper level trough is setting up over the northeastern CONUS, resulting in a prolonged cold spell with below normal temperatures certain.
232 PM CST Sat Jan 22 2022 The Rex Block persists over the western CONUS this afternoon with a deep trough anchored over the east.
Aloft, flow becomes quasi-zonal over our area as a longwave trough moves over the eastern CONUS. At the surface, high pressure will shift down to our southwest providing us with light southwesterly winds that help bring temperatures up to the low to mid 30s.
200 PM MST Sat Jan 22 2022 Current surface map places low over western North Dakota with warm front into central South Dakota. Not expecting any freezing rain tonight. Surge of low level warm advection on Sunday will result in highs around 10 degrees warmer than today.
1250 PM EST Sat Jan 22 2022 High pressure will provide cold and dry conditions through Sunday morning. A weak cold front should bring snow showers to southeast West Virginia during Sunday evening into Sunday night.
This will all be gradually settling south through the day with the front as it continues it's slow push southward, with cooler and drier high pressure starting to clear out the area tonight from the north.
1253 PM EST Sat Jan 22 2022 Cold and dry weather continues today under high pressure.
The low clouds will clear later this morning into this afternoon, lingering the longest over the Umpqua.
248 PM CST Sat Jan 22 2022 Northwest mid/upper flow prevails across the Central CONUS with a mean mid/upper trough along and north of the Great Lakes area.
Ridge of high pressure will be over the region the next couple of days. This will keep relatively quiet weather across the region except for the typical fog and freezing fog. Otherwise current forecast is on track with freezing fog expected to reform and become more widespread tonight.
Ridge of high pressure will be over the region the next couple of days. This will keep relatively quiet weather across the region except for the typical fog and freezing fog. Otherwise current forecast is on track with freezing fog expected to reform and become more widespread tonight. High pressure will provide generally clear skies aside from some high cirrus over the next 24 hours but will also see the development of fog and stratus as an inversion strengthens over the Columbia Basin and adjacent areas. This morning a stratus deck has developed coming out of the Columbia Gorge into the Lower Columbia Basin impacting DLS with MVFR CIGs. Tonight am expecting the low stratus and fog to be more widespread with LIFR and IFR conditions developing after 03Z at PSC and ALW and after 09Z at YKM, ALW, PDT and DLS.
Long-wave upper level troughing persists across the eastern CONUS with generally zonal flow aloft over the southeast U. A remarkably dry airmass advects into the area through tonight and Sunday morning, characterized by PWATs dipping below a tenth of an inch by Sunday morning as high pressure settles in just west of the area. For the rest of today, dry weather continues and temperatures climb into the lower to middle 40's for inland locations and middle to upper 40's across southwestern AL and the FL panhandle. Likewise dry weather and clear skies favor a large diurnal cycle with temperatures rising into the lower 50's for many locations Sunday afternoon.
Amplified upper pattern continues with broad cyclonic flow around a deep Hudson Bay low and a west coast ridge rounding the top of a cutoff low in the Baja region.
/SVH 18Z TAFS: Dominating high pressure in place will continue light winds and persistent strengthening inversions for most of the Inland Northwest. Pullman will carry the lowest risk given a light southeast wind. The Columbia basin will see the low clouds swirl around. Inversions are strongest over this area and it will be very difficult to mix this fog out today relying only on the low January sun angle to burn it off.
Trough axis is moving through with winds shifting to the northwest by late afternoon and inversion heights falling to around 5 kft. The mid to near term models consistently show a deepening trough that is coupled with a 850mb thermal trough consisting of an arctic air mass with 850mb temps.
155 PM EST Sat Jan 22 2022 Today troughing over the eastern CONUS and a blocking ridge in place over the northeastern Pacific will result in northwesterly flow overhead and a change in our sensible weather.
122 PM EST Sat Jan 22 2022 High pressure with some bitterly cold air will be over the region through today. A deep upper level trough is setting up over the northeastern CONUS, resulting in a prolonged cold spell with below normal temperatures certain.
The bulk of the frontal zone remains to the north of the Keys, with high pressure well-removed to the northwest, centered near the ArkLaTex. Note that the combination of the near-saturated boundary layer reinforced by a little light rain aloft over the cooler West Florida Shelf may result in a rapid return of stratus and some fog later this evening. Continuing with the previous synopsis, a cold front will push through the coastal waters of the Florida Keys tonight or Sunday morning, followed by fresh northerly breezes Sunday afternoon and Sunday night.
Highs will likely top out in the lower to middle 40s for most of the area, with 50s over the northeastern Permian Basin and across the Rio Grande Valley and portions of the Marfa Plateau. Cloud cover will continue expanding overnight, limiting radiational cooling and keeping temperatures in the lower to middle 30s across the Permian Basin, Trans Pecos, and portions of the Rio Grande Valley, with lows in the middle to upper 20s elsewhere.
Highs will be slightly warmer today in the upper 30s and lower 40s. BW Chattanooga Airport, TN 43 24 48 27 52 / 0 0 0 0 0 Knoxville McGhee Tyson Airport, TN 40 22 45 26 48 / 0 0 0 0 0 Oak Ridge, TN 41 22 46 24 47 / 0 0 0 0 0 Tri Cities Airport, TN 39 19 41 23 44 / 0 0 0 0 0.
347 PM EST Sat Jan 22 2022 High pressure weakens across the area tonight. A cold front moves through Sunday evening.
Stable conditions will continue through the short term period with high pressure centered over the ArkLaTex and extending east through the Deep South. Expect temperatures to fall generally into the lower 20s area-wide. Afternoon highs should be several degrees warmer due to the zonal flow aloft and sunny skies.
(The rest of today ) A mostly sunny and warmer day is in progress across eastern Oklahoma and northwest Arkansas.
Temperatures tonight will be on the warmer side as the cloud cover won't allow for efficient cooling to occur. Overnight lows are forecast to range in the low to mid 40s area- wide. An upper level low will be traversing eastward across northern Mexico/Desert Southwest tomorrow, before reaching the western portions of the state by tomorrow night. As this happens, a coastal trough will develop over western portions of the Gulf bringing an influx of deeper moisture into the region by late Sunday night. However, as we head into Sunday night showers could become more likely owing to the combination of the approaching upper level disturbance, the surface coastal trough and deep rich moisture available.
225 PM MST Sat Jan 22 2022 An upper low will affect Arizona and southeast California this weekend with breezy to windy conditions and isolated to scattered light showers at times.
Upper level ridging will keep things nice and pleasant the next couple days, with southerly winds helping promote the warmup. Lows will still remain below freezing, with lows Saturday night into Sunday remaining in the mid to upper 20s.
334 PM CST Sat Jan 22 2022 - Seasonable temperatures will exist into Sunday, albeit a touch cooler.
Cold Canadian high pressure building into the region is producing cold air advection from the Deep South southward into the FL Peninsula. With light winds abundant low level moisture and temps near freezing in N FL have added frost for Levy and N Citrus Counties tonight. /issued 257 PM EST Sat Jan 22 2022/ The cold front is currently pushing through the southern most zones this afternoon, with light areas of rain in place across the CWA along with overcast low clouds. The rain and clouds will be slowly clearing out of the area overnight from north to south as cooler and drier high pressure starts to build into the area from the NW.
Relatively quiet across the forecast area early this afternoon, with strengthening southwesterly flow gradually ushering in some warmer air. However, dry air in the lowest levels is expected to win out, with a few sprinkles and/or flurries being the most those areas get. Sunday looks to be quite similar to today though perhaps a few degrees cooler.
/issued 232 PM CST Sat Jan 22 2022/ The Rex Block persists over the western CONUS this afternoon with a deep trough anchored over the east.
An upper low will affect Arizona and southeast California this weekend with breezy to windy conditions and isolated to scattered light showers at times.
514 PM CST Sat Jan 22 2022 - Seasonable temperatures will exist into Sunday, albeit a touch cooler.
These are the counties where we should see the highest accumulations.
214 PM MST Sat Jan 22 2022 As the main trough that affected us yesterday moves across the High Plains region, a ridge of high pressure will build off of the Pacific Coast.
A ridge of high pressure will continue to cause valley inversions throughout the Northern Rockies.
Areas of morning freezing fog are possible Sunday morning associated with a strong temperature inversion.
High pressure over Northern California with a low pressure system centered in southwest Arizona will continue over the next day before the low begins to move eastward. Have issued a wind advisory through 10 am Sunday due to strong ridgetop winds and favored mountain locations expected to have wind gusts topping 50 mph.
/Issued 155 PM EST Sat Jan 22 2022/ Today troughing over the eastern CONUS and a blocking ridge in place over the northeastern Pacific will result in northwesterly flow overhead and a change in our sensible weather.
Winds are expected to be mostly below 10 knots through the period, and there are no signs of fog forming in the next 30 hours by any of the higher res models so far. The cloud cover should keep temperatures warmer tonight compared to last night.
Early morning low temperatures will average between the mid 20s to freezing, but more in the mid 30s near the Colorado River Valley. No matter, increasing west or southwest winds coming off the higher terrain of the Big Country/West-Central Texas and abundant sunshine/insolation will work in conjunction with weak low level WAA for highs in the lower to mid 60s for most areas, though upper 50s can be expected where thicker high cloudiness exists across western Central Texas.
High pressure at the surface will settle across the region during the period.
