Lows tonight will drop into the lower to mid 20s with afternoon highs tomorrow in the mid 40s to lower 50s.
At this time with NW winds 4-6 knots forecasted, widespread frost is unlikely since low temperatures should stay just above freezing.
(Rest of today through Friday) A cold front has worked its way through the Southern Florida peninsula this morning and afternoon leading to isolated showers and increased cloud-cover across the area.
North Georgia cloud cover is squeezing out enough moisture to produce snow flurries in the higher elevations, unfortunately below radar beam level. Broad, confluent WSWly flow in place thru the forecast, along southern periphery of large, positively-tilted upper trough over the eastern and southern CONUS.
(This evening through Friday) Tonight will be slightly warmer than this morning but still on the chilly side with overnight lows in the upper teens to near freezing.
930 PM EST Thu Jan 26 2023 Some of the high resolution models have shown one final round of light snow/flurries overnight tonight north of I-40. These showers will remain a possibility through the rest of the day before the low level moisture gets wrung out or moves off to the northeast with the low heading into New England. Some additional light snow accumulations are possible in the higher elevations of northeast TN and southwest VA, but outside of there it should be too warm to see anything stick to the ground before precipitation comes to an end.
547 PM CST Thu Jan 26 2023 (This evening through Friday) Currently, visible satellite indicates most areas are snow free except for areas that received the highest snowfall in western Oklahoma as well as south central Oklahoma. This has kept the highs in the areas impacted by snow in the low to mid 40s, while everywhere else has increased into upper 40s to the low 50s. Breezy winds tonight will keep the low temperatures higher, with lows increasing into the upper 20s and low 30s.
There may be some frost across the interior sections of SE GA and NE FL during the pre-dawn hours trough about an hour after sunrise. At this time with NW winds 4-6 knots forecasted, widespread frost is unlikely since low temperatures should stay just above freezing.
Mild temperatures through tomorrow but cooler over the weekend.
552 PM EST Thu Jan 26 2023 High pressure will persist into the weekend. Low temperatures will be a few degrees cooler than normal, generally ranging from low 30s/around freezing across the interior to mid/upper 30s closer to the coast.
847 PM EST Thu Jan 26 2023 High pressure continues across the area tonight.
649 PM EST Thu Jan 26 2023 Weak high pressure will build east of the region tonight. Warm air on southerly winds will be pulled into the region during the day, ahead of a weak cold front washing out over northern Ohio in the evening.

This has kept the highs in the areas impacted by snow in the low to mid 40s, while everywhere else has increased into upper 40s to the low 50s. Breezy winds tonight will keep the low temperatures higher, with lows increasing into the upper 20s and low 30s.
524 PM CST Thu Jan 26 2023 A cold night is in store for the Mid-South as temperatures drop below freezing by Friday morning.
548 PM CST Thu Jan 26 2023 (This evening through Friday Night) High pressure has built over SE Texas providing up with mostly clear skies and a cool, light northerly flow. This high pressure will slide towards the Central Gulf Coast tomorrow bringing a more southerly flow into our region. This will bring increasing moisture and temperatures with daytime temperatures climbing into the low 60s - about five degrees higher compared to today.
A cold night is in store for the Mid-South as temperatures drop below freezing by Friday morning.
--------------------------------------------------------------------- Key Messages: - Clouds/light snow clearing out this evening - Gusty 30-40kt winds tomorrow --------------------------------------------------------------------- Broad upper-level troughing is leading to overcast low clouds and light snow showers moving through the area, currently. We will remain dry as weak upper-level ridge moves over the region in the overnight hours. Thinning cloud cover will allow ample radiational cooling, to bring low temperatures into the low-mid 20s overnight.
404 PM EST Thu Jan 26 2023 Weak high pressure will build east of the region tonight. Warm air on southerly winds will be pulled into the region during the day, ahead of a weak cold front washing out over northern Ohio in the evening.
510 PM CST Thu Jan 26 2023 (Tonight) A troughing west/ridging east upper air flow pattern continued across the greater North American domain. Upper ridging out west was part of an Omega-style block (troughing west and east of the ridge). More clear skies will result in lows cooling into the mid 20, with slightly warmer readings near large bodies of water.
An additional inch and half could accumulate in the higher terrain due to upsloping into late Friday morning. Actually, if conditions permit, may cancel the Winter Weather Advisory in the West Virginia/ Pennsylvania ridges before midnight. Late Friday morning through Friday evening is expected to be mostly dry under a ridge across the East Coast.
928 PM EST Thu Jan 26 2023 Weak high pressure will build east of the region tonight. Warm air on southerly winds will be pulled into the region during the day, ahead of a weak cold front washing out over northern Ohio in the evening.
Band of moderate snow with the warm front continues to push eastward. MBG has risen into the low 30s with moderate snowfall.
Accumulating snowfall is most likely in the higher elevations of northern Elko county.
A winter weather advisory continues until midnight for Somerset and Cambria counties, where an additional coating to a couple inches of snow is possible, with highest amounts in the high terrain. Lake enhanced/orographic snow showers will diminish over the Alleghenies and gusty winds will diminish everywhere Friday, as surface ridging builds into the area. Mixing down model 850mb temps of -10C yields expected highs near seasonable levels Friday, ranging from the upper 20s over the northwest mountains, to near 40F across the Lower Susq Valley.
(Tonight) Lingering cloud cover from earlier has given way to an influx of seasonably cooler air from the NW. High pressure building into the region from the west will help the quiet/cool wx pattern prevail well into the morning hrs Fri.
(This evening through Friday Night) High pressure has built over SE Texas providing up with mostly clear skies and a cool, light northerly flow. This high pressure will slide towards the Central Gulf Coast tomorrow bringing a more southerly flow into our region. This will bring increasing moisture and temperatures with daytime temperatures climbing into the low 60s - about five degrees higher compared to today.
533 PM CST Thu Jan 26 2023 (This evening through Friday) Tonight will be slightly warmer than this morning but still on the chilly side with overnight lows in the upper teens to near freezing.
This will allow surface winds to back to the southwest to south once again, bringing in warmer weather for the last part of the work week and into the early part of the weekend. With temperatures below freezing it will start off as very light snow/flurries, then transition to light rain/sprinkles before moving out by midday Friday. As for low temperatures tonight, it will be a bit warmer, in the upper teens to mid 20s. On Friday, highs will be around 20 degrees warmer than today, in the mid 40s to around 50 degrees.
315 PM CST Thu Jan 26 2023 Band of moderate snow with the warm front continues to push eastward. MBG has risen into the low 30s with moderate snowfall.
513 PM CST Thu Jan 26 2023 A few flurries remain in the Evansville Tri-State area, with most of the precipitation having moved off east as the main low pressure system has moved towards Northern New England. A sharply tilted trough axis will cross the Quad State tonight bringing temporarily clearing skies and colder air with lows in the near 20 to mid 20s range. Between that system and high pressure in the deep south, the pressure gradient will increase, with winds increasing to 15-20 mph tomorrow with gusts of 25-35 mph. Warm advection with rising heights results in highs in the mid 40s to lower 50s and lows near freezing.
A band of moderate to heavy snow continues to move east across central North Dakota this afternoon ahead of a surface warm front located over the west. This warm front was extending south from low pressure centered over southeastern Saskatchewan near the Manitoba border. Behind the warm front across the west and central, temperatures should rise above freezing in most areas. A cold front will then approach from the north tonight, extending west southwest from the low. However, the best chances for some light snow will be in the afternoon and evening across the far west, associated with another cold front and reinforcing shot of arctic air.
These less robust winds could be due to the nature of the warm air mass riding the strong winds as opposed to a cold air mass intrusion or cold front which would more easily drive down those stronger winds from aloft.
High pressure will build overhead from the west through the day Today. With the exception of areas south of Gainesville, where highs will climb into the lower 60s this afternoon, most areas will remain in the mid to upper 50s. For Tonight, the high will be centered just to the north.
Accumulating snowfall is most likely in the higher elevations of northern Elko county. Accumulating snowfall is most likely in the higher elevations of northern Elko county.
Winds will remain relatively calm along the Highway 25 corridor eastward thus creating the productive environment needed to efficiently radiate.
349 AM EST Fri Jan 27 2023 High pressure will persist through most of the weekend.
1005 PM CST Thu Jan 26 2023 (Tonight) Lingering cloud cover from earlier has given way to an influx of seasonably cooler air from the NW. High pressure building into the region from the west will help the quiet/cool wx pattern prevail well into the morning hrs Fri.
1135 PM CST Thu Jan 26 2023 (This evening through Friday Night) High pressure has built over SE Texas providing up with mostly clear skies and a cool, light northerly flow. This high pressure will slide towards the Central Gulf Coast tomorrow bringing a more southerly flow into our region. This will bring increasing moisture and temperatures with daytime temperatures climbing into the low 60s - about five degrees higher compared to today.
1234 AM EST Fri Jan 27 2023 High pressure will persist into the weekend. Since the ridge axis associated with the high to the west stays west of the Appalachians, this maintains just enough mixing to prevent ideal radiational cooling.
Guidance indicates the highly modified post-frontal airmass will remain quite shallow, with the sharp wind discontinuity perhaps evolving into a more veering pattern late tonight from 2000-5000 feet, implying some isentropic lift. A Small Craft Advisory remains in effect for the Gulf waters north of the Lower Keys and beyond 5 fathoms including the Dry Tortugas. Small craft should exercise caution for the Bayside and Gulfside inside of 5 fathoms, and the Straits of Florida west of the Seven Mile Bridge. From synopsis, high pressure will continue to build into the region overnight and Friday.
1047 PM CST Thu Jan 26 2023 (This evening through Friday) Currently, visible satellite indicates most areas are snow free except for areas that received the highest snowfall in western Oklahoma as well as south central Oklahoma. This has kept the highs in the areas impacted by snow in the low to mid 40s, while everywhere else has increased into upper 40s to the low 50s. Breezy winds tonight will keep the low temperatures higher, with lows increasing into the upper 20s and low 30s.
1017 PM EST Thu Jan 26 2023 Temperatures are trending slightly cooler, so overnight minimum temperatures have been adjusted accordingly.
Although clouds will generally increase, temperatures should still be a few degrees warmer overall with highs in the upper 50s to around 60. With winds remaining breezy through tonight, lows will be warmer as well, dropping into the upper 30s to lower 40s, as opposed to the freezing temperatures we've seen the last few nights.
Temperatures will fall below freezing over the entire area overnight, so we do expect that what little snow falls will stick. MVFR conditions possible across the lower valleys in SW Idaho aft 27/18z with a rain/snow mix.
1206 AM EST Fri Jan 27 2023 Temperatures are trending slightly cooler, so overnight minimum temperatures have been adjusted accordingly.
High pressure will start building in, leaving us with mostly clear skies for Friday. Temps are currently in the low 30s to upper 20s. Winds will be calm overnight, allowing temperatures to fall into the low- to- mid 20s. Lows tonight will drop into the lower to mid 20s with afternoon highs tomorrow in the mid 40s to lower 50s.
While, not expecting the lows to be more than a degree or two lower than previously forecast, the drop in winds could have significant impact on frost potential toward dawn.
Winds respond from the south making for a milder night tonight as well, with some locales remaining in the lower 40s overnight.
1222 AM EST Fri Jan 27 2023 Some of the high resolution models have shown one final round of light snow/flurries overnight tonight north of I-40. These showers will remain a possibility through the rest of the day before the low level moisture gets wrung out or moves off to the northeast with the low heading into New England. Some additional light snow accumulations are possible in the higher elevations of northeast TN and southwest VA, but outside of there it should be too warm to see anything stick to the ground before precipitation comes to an end.
340 AM EST Fri Jan 27 2023 A weak area of high pressure builds over Maine today, as a storm system tracks northeast through the Maritimes.
1110 PM CST Thu Jan 26 2023 A few flurries remain in the Evansville Tri-State area, with most of the precipitation having moved off east as the main low pressure system has moved towards Northern New England. A sharply tilted trough axis will cross the Quad State tonight bringing temporarily clearing skies and colder air with lows in the near 20 to mid 20s range. Between that system and high pressure in the deep south, the pressure gradient will increase, with winds increasing to 15-20 mph tomorrow with gusts of 25-35 mph. Warm advection with rising heights results in highs in the mid 40s to lower 50s and lows near freezing.
The dry air left behind will set up a rapid temperature recovery in the morning, and with the light winds, Friday will feel even warmer.
118 AM EST Fri Jan 27 2023 Weak high pressure will build east of the region tonight. Warm air on southerly winds will be pulled into the region during the day, ahead of a weak cold front washing out over northern Ohio in the evening.
Regional METAR observations from across the state are showing the much cooler and drier airmass filling into the forecast area this morning, with temperatures approaching freezing over parts of the Nature Coast.
1012 PM EST Thu Jan 26 2023 High pressure will persist into the weekend. A west-southwest flow will prevail throughout much of the vertical, between an anticyclone centered over Cuba and the southeast Bahamas and fast moving short waves traversing the Northern Plains, the Upper Mississippi Valley and the Great Lakes. At the surface, high pressure will continue to build from the west through the night, resulting in PWat just 40-50% of normal. Since the ridge axis associated with the high to the west stays west of the Appalachians, this maintains just enough mixing to prevent ideal radiational cooling.
1034 PM CST Thu Jan 26 2023 (This evening through Friday) Tonight will be slightly warmer than this morning but still on the chilly side with overnight lows in the upper teens to near freezing.
(Today) A pleasant end to the work week is expected today as high pressure along the Gulf Coast dominates the local weather. Subsidence under the high will result in a mostly sunny day. As a longwave upper level trough slides east today, CAA will not be as strong as yesterday. Therefore, expect afternoon temperatures to rise up to near the climatological normals in the lower 50s.
1221 AM EST Fri Jan 27 2023 (Rest of today through Friday) A cold front has worked its way through the Southern Florida peninsula this morning and afternoon leading to isolated showers and increased cloud-cover across the area.
Up to an additional inch and half could accumulate in the higher terrain due to upsloping into late Friday morning. Late Friday morning through Friday evening is expected to be mostly dry under a ridge across the East Coast.
521 AM CST Fri Jan 27 2023 Surface analysis at 0800 UTC shows an area of low pressure near the US-Canadian border, with a cold front draped to its south across the Upper Mississippi Valley. Further south, chances of rain showers increase with the trailing cold frontal passage Saturday night. As the low-level cold air comes in behind the front, the rain may mix in with or briefly changeover to snow or freezing rain/drizzle before ending. The reason that freezing drizzle/rain is possible is that some model guidance suggests a largely unsaturated dendritic growth zone.
Lows tonight should generally be in the low to mid 30s.
Temperatures are falling below freezing again. Arctic high pressure will build in from the northwest on Saturday, pushing the precip south with the front edge of the arctic front. Will start under an Arctic airmass with the center of a 1040mb high over northern Montana and a ridge extending east into the eastern Dakotas and western Minnesota.
Today and tomorrow will be warmer and windier than previous days thanks to increasing southwesterly surface flow in response to lee troughing in SE CO and the Panhandle. Highs this afternoon will reach the mid to upper 50s under clear skies, while lows overnight should be 5-10 degrees warmer than previous nights as clouds move back in.
510 AM CST Fri Jan 27 2023 (Today) A pleasant end to the work week is expected today as high pressure along the Gulf Coast dominates the local weather. Subsidence under the high will result in a mostly sunny day. As a longwave upper level trough slides east today, CAA will not be as strong as yesterday. Therefore, expect afternoon temperatures to rise up to near the climatological normals in the lower 50s.
327 AM CST Fri Jan 27 2023 Forecast Highlights: -A weekend cold front brings in a frigid air mass and wind chills below zero. Forecast Discussion: At 09Z today, water vapor imagery shows a trough axis associated with a system centered over northern MN moving over northeastern KS. Increased cloud cover and perhaps some flurries have been associated with the trough, which is quickly moving east very early today.
Night time microphysics satellite imagery has been depicting boundaries associated with the cold front that moved though the Florida Keys yesterday. Temperatures in the island chain are in the mid to upper 60s, with dewpoints in the lower 60s Temperature-wise, today and tonight will be the "cooler day/night" of the weekend with highs in the lower 70s degree Fahrenheit and lows in the upper 60s.
Temperatures will begin a cooling trend as a a pair of low pressure systems will drop southward over the West Coast this weekend.
- Warmer conditions Friday and Saturday for most locations.
301 AM PST Fri Jan 27 2023 A trough from the north will influence the weather this weekend with gradual cooling occurring as winds turn onshore.
633 AM EST Fri Jan 27 2023 High pressure will build into the forecast area and remain in control of the region through Saturday.
316 AM CST Fri Jan 27 2023 Surface analysis at 0800 UTC shows an area of low pressure near the US-Canadian border, with a cold front draped to its south across the Upper Mississippi Valley. Further south, chances of rain showers increase with the trailing cold frontal passage Saturday night. As the low-level cold air comes in behind the front, the rain may mix in with or briefly changeover to snow or freezing rain/drizzle before ending. The reason that freezing drizzle/rain is possible is that some model guidance suggests a largely unsaturated dendritic growth zone.
Colder rural, outlying areas across the lower elevations will likely see low temperatures this morning fall to around the freezing mark. Some Phoenix suburbs, such as Queen Creek, may also see temperatures this morning flirt with the freezing mark. An amplified upper level ridge over the eastern Pacific will continue to promote a dry northerly flow over the region heading into the weekend with tranquil weather prevailing.
304 AM CST Fri Jan 27 2023 An upper trough will move out of the Northern Plains today and into the Upper Mississippi Valley. This will send a cold front down the Plains with well below normal temperatures behind it.
Overnight lows chilly across the north with L40s for much of Lake and inland Volusia counties, however, any delay with thin high clouds across the north and we could realize some U30s in normally cooler rural locations. High pressure pushing across the Gulf Coast will extend its reach to southeast U. Conditions will remain less than ideal for small craft as wind speeds support 15-17kts over the Gulf Stream/Treasure Coast waters and 10-15 kts elsewhere with some higher gusts as this wind component opposes the warmer, northerly flowing Gulf Stream.
422 AM MST Fri Jan 27 2023 Current surface analysis shows low pressure along the MN/Canadian border, with warm front well east of the forecast area and arctic front from central ND to northeast MT. Upper level analysis shows broad trough covering the central and eastern US, with ridge remaining off the west coast.
At this time we plan on maintaining the Winter Weather Advisory but I would not be surprised if we had a few reports come in with locally higher amounts of 6 inches or greater in the higher terrain. However, a much tighter spread of warmer temperatures does reappear Friday.
Forecast soundings show a small window for some drizzle/freezing drizzle as the mid layers dry out, but this is very short-lived as the entire sounding aside for a thin layer of stratus becomes unsaturated as the cold front pushes through. This cold front is also quite impressive, with gusts of 40 to 45 mph widespread across the Dakotas.
511 AM CST Fri Jan 27 2023 (Today and tonight) SIGWX NIL today as an inverted trough stretching from northern Baja California to the Red River Valley continues to sag southward with a broad fetch of northwesterly flow building in behind over the CWA. However, locations where the snowpack remains present will experience much shallower PBL mixing, yielding much cooler temperatures compared to locales in the immediate vicinity without snow. , trending cooler and more moist) to best capture these highly localized mesoscale effects the snowpack will cause on the sensible heat flux budget with the expectation of significant sublimation and melting of the snowpack occurring due to the southwesterly breeze. Surface winds will remain breezy overnight tonight as the lee cyclone drifts into west-central Kansas, resulting in a slight uptick in low temperatures on Saturday morning.
At the surface, high pressure was centered near the Sabine River. High pressure will slide eastward to the Carolina coast by Saturday evening. Most temperature guidance is within a couple degrees through tomorrow, have trended on the warmer side where there are discrepancies.
403 AM EST Fri Jan 27 2023 High pressure builds into the Mid-Atlantic through tonight, pushing offshore on Saturday.
633 AM EST Fri Jan 27 2023 High pressure will build into the area today and Saturday, ending the mountain snow showers and with wind speeds gradually diminishing.
