100 AM EST Thu Jan 26 2023 A swath of light to moderate showers associated with a cold front will continue from just west of highway 301 to the offshore waters this early evening. Afterwards, behind the front we can expected much cooler, drier conditions. Mostly cloudy conditions will be present tonight, with breezy winds shifting from SW to NW with the passage of this cold front. (Thursday through Friday night) Dry weather and cooler temperatures will persist Thursday and Friday after the passage of the cold front. Lows Thursday night will be just above freezing for inland SE GA, and the upper 30s and 40s elsewhere. With lows dropping below freezing Friday night for inland SE GA and the Suwannee valley, a light freeze and areas of frost is possible.
Some slightly breezy northwest winds noted over Hill Country with cooler than normal high temperatures expected later this afternoon. The quiet weather remains as high pressure continues to influence the area through the short term period. Areas in the Hill Country and along and off of the Escarpment will see freezing or slightly below freezing temperatures, coldest Thursday morning. Mid to low level clouds begin to move over south central Texas early Friday morning, which may allow for slightly warmer low temperatures in the far southern portion of the area depending on timing.
Winds into Friday look to increase shortly after the passage of the cold front, but don't appear to stick around much after that. Gusty south winds shift to the northwest late Thursday night (around 06Z) with even stronger gusts and potential for additional blowing snow impacts as a strong cold front arrives.
104 AM EST Thu Jan 26 2023 The cold front will cross the area early tonight pushing remaining showers out or the area. On Thursday high pressure will build into the region along with cool and dry conditions.
323 AM EST Thu Jan 26 2023 High pressure will build into the region today along with breezy, cool, and dry conditions.
Cooler readings across the snowpack will be possible across the northern zones with 40s here. Even with the warmer temperatures, forecast minimum relative humidity is expected to only bottom out around 25 percent, so does not appear that Friday will have any slam dunk fire weather/red flag concerns given the relatively cool and moist conditions.
Broad, confluent WSWly flow in place thru the forecast, along southern periphery of large, positively-tilted upper trough over the eastern and southern CONUS.
A deep trough is stretched across most of the country, pushing towards the east coast by tonight. Low pressure in Ohio is moving towards the northeast. Progression of a trough axis and a very weak disturbance from the Upper Midwest will result in a chance of flurries overnight into Thursday, mainly for the eastern half of the forecast area. Despite winds shifting to southwesterly tomorrow night, clearing of skies will allow for lows to drop to the lower half of the 20s with near 20 values in areas with lingering snow cover. Low pressure moves across Ontario north of Lake Superior but precipitation on Friday is expected to stay north of the Quad State.
High pressure will strengthen across the area today, with mostly sunny skies and highs ranging from the mid 40s north to the mid 50s in the south.
At the surface, a trough is centered over the Dakotas, and winds are northwesterly at 15-25 mph, gusting up to 30 mph. Another factor with Round 2 will be stronger northwesterly winds behind the warm front. As the aforementioned low moves into the Great Lakes region, its cold front will slide south.
1048 PM EST Wed Jan 25 2023 The cold front will cross the area early tonight pushing remaining showers out or the area. On Thursday high pressure will build into the region along with cool and dry conditions.
131 AM EST Thu Jan 26 2023 A low pressure system will exit the Ohio Valley to the east tonight.
Expect gradual clearing skies from west to east overnight, with low temperatures in the lower/mid 30s north of I-10, mid/upper 30s along and south, to near 40 along the coast. Thursday will be sunny across the region, but still quite chilly with temps only reaching the lower to middle 50s. Thursday morning and again on Friday morning will see freezing temps impacting much if not all of the nrn 1/2 of the area as high pressure settles overhead. As high pressure moves to the east, southerly or southeasterly low-level flow is expected to redevelop Friday late day, which will allow for a bit of a warm up with highs progged to reach the upper 50s for a large chunk of the area.
Skies will start to clear out from west to east by Thursday afternoon as high pressure builds in the region though temps will be well below normal.
Cooler conditions persist through Friday morning, with near to High pressure and continued dry zonal (west to east) flow will keep below normal temperatures and fairly dry conditions over the area.
Clouds have helped keep temperatures a little warmer than otherwise. Scattered clouds will begin to redevelop/spread back over region today as positive tilted upper level trough shifts slowly southeast.
As temperature's continue to warm expect that these light snow showers will transition to more cold rain showers the rest of the day in the lower elevations of the valley. Discussion: A mid/upper level trough will be crossing the area today.
This activity is rotating around the west and south sides of the upper low that brought us the rain and wind yesterday. As usual, the highest snow accumulations will be in the favored upslope areas on the western edge of the Plateau from Bon Air Mountain northward through Monterey and Pleasant Hill to around Jamestown. Temperatures will remain near freezing this morning then rise above freezing during the day, so any snow accumulations should mainly be on grass and elevated surfaces, with roads just staying wet.
537 AM EST Thu Jan 26 2023 (Today through Tonight) Dry weather, cooling temperatures, and clearing skies will be in place today as high pressure settles in over the region following the frontal passage.
Elsewhere under the stars, most sites are in the low to mid 30s with frost developing. An area of high pressure over NE New Mexico is still pushing in our direction and will settle into E TX overnight with 1029mb. After bottoming out to start the day, a return flow of moisture and warmer temperatures will end the short term period.
524 AM CST Thu Jan 26 2023 (Today through Friday) Mostly sunny skies will continue today with cooler than normal temperatures across South Texas. Cloudy skies will continue to keep temperatures cooler on Friday with highs in the upper 50s to low 60s.
746 AM EST Thu Jan 26 2023 A departing storm will head toward the Canadian Maritimes today while high pressure begins to slowly build in its wake.
At 930 AM, visible satellite imagery showed a cold front across east central Florida from southeast Lake county to southern Volusia county. Cold front is pushing SE across the local Atlc waters early this morning and will push south of Jupiter Inlet by early afternoon.
A warm surge of temps will occur as the snows band moves east and winds turn west with temps rising into the low 30s for many in eastern ND and 20s elsewhere. HRRR and NAM 12 indicate what is likely the main cold front dropping south thru GFK 08/09z.
532 AM CST Thu Jan 26 2023 A quiet pattern will perpetuate the end of the week and weak ridging will begin to build in. Low level wind flow will remain mostly out of the northwest today which will counter some of the ridging this afternoon. Additionally, there is a weak upper level disturbance coming into the CWA ahead of the ridge which will keep the clouds rather thick as well. Tonight, the winds will begin to shift to the southwest as the mid and upper ridging will continue to build.
Clear skies will persist today, with temperatures warming into the lower 40s to lower 50s and the warmer temperatures off the Caprock. Weak lee troughing will develop overnight with the southwest surface winds picking up to around 10 to 20 mph across the northern half of the forecast area.
510 AM CST Thu Jan 26 2023 A few sprinkles/snow flurries are continuing in the low level curvature behind our departing storm system. A storm system over the Great Lakes region combines with surface ridging over the deep south to produce what looks like a fairly breezy day Friday with winds out of the southwest. Temps should recover a bit with the low level warm advection into the mid 40s to low 50s.
(Today through Friday night) Large scale cyclonic flow continues to dominate the CONUS as a longwave trough moves into the Great Lakes region. In its wake a secondary trough axis, with an extremely positive tilt, will rotate into the Plains today leading to strong subsidence under the left entrance region of a 250mb jet.
946 AM EST Thu Jan 26 2023 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.
Upper level ridging off the West Coast in the short term leaves the central U. The high out west breaks down tomorrow causing upper flow to become more northwesterly.
A strong 1042 mb high pressure is located over the NE Pacific, promoting quiet weather conditions.
647 AM EST Thu Jan 26 2023 Early morning IR satellite imagery is showing a band of cloudiness draped across the Florida Peninsula as the cold front pushes into southwest Florida. The northwest flow will also advect in a significantly cooler airmass, with afternoon highs topping out in the low 60s over the Nature Coast this afternoon, and mid 60s to mid 70s farther south. Lows tonight will drop to near (but not quite) freezing over the Nature Coast, and into the 40s and low 50s over central and southern portions of the forecast area tonight into Friday morning. North winds around 5-10 mph at sunrise will also contribute to the wind chill measuring about 5 degrees cooler than the observed low.
924 AM EST Thu Jan 26 2023 An upper level trough and cold air filtering into the area will lead to snow showers today. High pressure will offer cold temperatures and a brief period of dry weather tonight into Friday morning. Total snow accumulation is expected to be around an inch in most locations with 1 to 2 inches possible across the north -- especially the Bellefontaine ridge. High temperatures to range from the mid 30s northwest to the lower 40s southeast.
The pressure gradient between this feature and high pressure along the Gulf Coast will create breezy southwest winds. A warm front will also pass through, the flow aloft will go more zonal, and temperatures will show an appreciable rebound to above normal levels. A new cold front will be on the horizon in the mid- Mississippi Valley.
537 AM CST Thu Jan 26 2023 (Today through Friday night) Large scale cyclonic flow continues to dominate the CONUS as a longwave trough moves into the Great Lakes region. In its wake a secondary trough axis, with an extremely positive tilt, will rotate into the Plains today leading to strong subsidence under the left entrance region of a 250mb jet.
There has been little change in the areas where the strongest winds are expected, so made no changes to the High Wind Warning. By Friday morning cold high pressure will begin pushing south from the Canadian prairies, resulting in upslope snowfall across central and southern Montana.
(Today through Friday) Mostly sunny skies will continue today with cooler than normal temperatures across South Texas. Cloudy skies will continue to keep temperatures cooler on Friday with highs in the upper 50s to low 60s.
528 AM EST Thu Jan 26 2023 A departing storm heads toward the Canadian Maritimes today while high pressure begins to slowly building in behind it.
High temperatures are forecast to be in the lower to middle 30s.
Current temperatures are in the mid to lowers 70s, with dew points in the low 70s. The main story of the day will be the passage of the cold front that we have been advertising for last couple of days. Friday high temperatures will be in the lower 70s, with lows in the upper 60s, ENJOY.
647 AM EST Thu Jan 26 2023 High pressure will build into the region today along with breezy, cool, and dry conditions.
At the surface, high pressure was over the southern Rockies. Forecast soundings would indicate below normal temperatures remain on tap for today and tomorrow, with tomorrow's highs a couple degrees warmer than today. With clouds departing, Friday morning lows will be much closer to freezing north of Lake Pontchartrain, but nothing unexpected for late January.
(Today through Friday Night) A chilly start to Thursday with temperatures dropping into the low 30s to low 40s. Temperatures in the low 30s can be expected across our far northern counties. This pattern will enhance the southerly flow at the surface; bringing a warmer and more humid Gulf airmass.
Coupled with temperatures above- freezing, the chances for snow continue to look less promising for those who are hoping some. A low chance (15%) of snow showers exists through this afternoon in higher elevations, primarily on ridge tops in southern middle TN and far northeast AL. High temperatures will peak in the low to mid 40s today as gusts continue to reach around 20 mph.
637 AM EST Thu Jan 26 2023 An upper level trough and cold air filtering into the area will lead to snow showers today. High pressure will offer cold temperatures and a brief period of dry weather tonight into Friday morning. Total snow accumulation is expected to be around an inch in most locations with 1 to 2 inches possible across the north -- especially the Bellefontaine ridge. High temperatures to range from the mid 30s northwest to the lower 40s southeast.
524 AM CST Thu Jan 26 2023 (Today through Friday Night) A chilly start to Thursday with temperatures dropping into the low 30s to low 40s. Temperatures in the low 30s can be expected across our far northern counties. This pattern will enhance the southerly flow at the surface; bringing a warmer and more humid Gulf airmass.
655 AM EST Thu Jan 26 2023 Snow showers at the higher elevations should taper off Thursday morning with dry conditions moving in.
240 AM PST Thu Jan 26 2023 Valley inversions and cooler than average temperatures persist through Thursday. This will bring patchy low clouds, freezing fog, and some air quality concerns in urban valleys.
439 AM EST Thu Jan 26 2023 An upper level trough and cold air filtering into the area will lead to snow showers today. High pressure will offer cold temperatures and a brief period of dry weather tonight into Friday morning. Total snow accumulation is expected to be around an inch in most locations with 1 to 2 inches possible across the north -- especially the Bellefontaine ridge. High temperatures to range from the mid 30s northwest to the lower 40s southeast.
143 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.
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.
Low temperatures tonight are forecast in the mid 30s for most locations, with some sheltered and drainage areas in the low 30s to upper 20s.
Cold conditions will continue as elevated winds contribute to wind chill values below freezing for the remainder of today. Otherwise, expect the cold to persist until tomorrow, when afternoon high temperatures return to the low to mid 50s.
A few sprinkles/snow flurries are continuing in the low level curvature behind our departing storm system. A storm system over the Great Lakes region combines with surface ridging over the deep south to produce what looks like a fairly breezy day Friday with winds out of the southwest. Temps should recover a bit with the low level warm advection into the mid 40s to low 50s.
/NEW/ /Through Tomorrow/ Pleasant weather conditions are expected through the end of the week across North and Central Texas as the region remains under the influence of high pressure. Radiational cooling will be maximized as light winds and clear skies prevail, resulting in another night with lows mostly in the low 30s. As southwest winds increase in response to a deepening system across the Plains tomorrow, high temperatures will warm into the low 60s, about 10 degrees warmer than today.
No precip is expected, clear skies, and mostly cooler than average temps throughout. As of 1920z, temps in the southern Texas Panhandle are in the low-to-mid 40s. Lows tomorrow night will be in the lower 20s in the northwest/upper 20s in the southeast.
/96 (Now through Friday) A broad upper level trough will continue to extend across most of the eastern half of the nation today before gradually deamplifying late tonight into Friday.
This setup should continue into the weekend, as blocking off of the west coast keeps setup of ridging west and troughing east.
Dewpoints have dropped into the mid to upper 60s and temperatures have remained steady in the lower 70s since the frontal passage. Enjoy the cooler air behind the front while it lasts because it will unfortunately be a brief cool down.
1128 AM CST Thu Jan 26 2023 (Today through Friday night) Large scale cyclonic flow continues to dominate the CONUS as a longwave trough moves into the Great Lakes region. In its wake a secondary trough axis, with an extremely positive tilt, will rotate into the Plains today leading to strong subsidence under the left entrance region of a 250mb jet.
The warm front has crossed into our CWA, behind which winds are WNW 25 to 35 mph. As the low slides into the Great Lakes region, its cold front will back into our CWA, and arctic air will begin infiltrating our area.
(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.
1029 AM EST Thu Jan 26 2023 A departing storm will head toward the Canadian Maritimes today while high pressure begins to slowly build in its wake.
Temps are running in the lower to middle 50s with a cool NW/N breeze under sunny skies.
125 PM EST Thu Jan 26 2023 An upper level trough and cold air filtering into the area will lead to snow showers today. High pressure will offer cold temperatures and a brief period of dry weather tonight into Friday morning. Total snow accumulation is expected to be around an inch in most locations with 1 to 2 inches possible across the north -- especially the Bellefontaine ridge. High temperatures to range from the mid 30s northwest to the lower 40s southeast.
Much of the area is clear, thus temps running a few degrees warmer. High pressure will strengthen across the area today, with mostly sunny skies and highs ranging from the mid 40s north to the mid 50s in the south.
349 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.
A high-amplitude upper ridge resides off the coast as a dry northerly flow aloft remains over our area today.
This precip will continue to quickly clear from NW to SE as our attention turns more to the High Winds expected today. There has been little change in the areas where the strongest winds are expected, so made no changes to the High Wind Warning. By Friday morning cold high pressure will begin pushing south from the Canadian prairies, resulting in upslope snowfall across central and southern Montana.
Went close to the NBM for the lows tonight which is about a category above MOS guidance. A mid level short wave trough over northern Mexico to Far West Texas this evening will weaken as it shears eastward into central Texas on Friday.
However, most of the day will feature cooler than average temperatures. Tonight will be warmer than last night due to the insulation of the overcast skies. As for Friday, an inverted trough creeps north towards the lower Texas coast bringing the next chance for rain.
This morning started off with light winds and dewpoints in the lower 70s. An interesting cloud phenomenon, a rope cloud along the leading edge of a weak cold front, made its way across the Florida Keys. Winds quickly shifted to the northwest to north behind the boundary, which brought in some cooler, drier air. Dewpoints dropped into the upper 60s and temperatures at our office have dropped from the upper 70s to the lower 70s. High pressure will build in behind the front, causing a sharp increase in winds by the afternoon in the western half of the forecast area. A Small Craft Advisory is currently in effect for Western Straits of Florida, Hawk Channel from west end of Seven Mile Bridge to Halfmoon Shoal, and Gulf waters north of the Lower Keys and beyond 5 fathoms including the Dry Tortugas.
1153 AM CST Thu Jan 26 2023 A quiet pattern will perpetuate the end of the week and weak ridging will begin to build in. Low level wind flow will remain mostly out of the northwest today which will counter some of the ridging this afternoon. Additionally, there is a weak upper level disturbance coming into the CWA ahead of the ridge which will keep the clouds rather thick as well. Tonight, the winds will begin to shift to the southwest as the mid and upper ridging will continue to build.
Update will adjust for cloud cover trends across far NE OK into far NW AR and also adjust temps slightly cooler across far NW AR where clouds and snow cover combination will limit warm up.
315 PM EST Thu Jan 26 2023 --------------------------------------------------------------------- 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.
1123 AM CST Thu Jan 26 2023 (Today through Friday Night) A chilly start to Thursday with temperatures dropping into the low 30s to low 40s. Temperatures in the low 30s can be expected across our far northern counties. This pattern will enhance the southerly flow at the surface; bringing a warmer and more humid Gulf airmass.
Rather benign conditions expected over most of the forecast period as high pressure moves east across the SE U. After cool and breezy conditions this afternoon under clearing skies and a much cooler night tonight, mostly sunny and cool conditions look to be on tap for Friday, with morning lows in the mid 30s north to around 50 south, warming into the 60s in the afternoon.
Cold sub-freezing temperatures move in tonight allowing for some areas of black ice so be careful driving. We warm up to just above freezing Friday, but another chance for snow arrives, which could have times of lowered visibility. Following a short lull in the precipitation, a low pressure system, which passes by to our north, swings a cold front through later in the day providing another chance for snow. Highs on Friday will likely be able to rise above freezing.
