409 PM CST Tue Jan 9 2024 Tonight through tomorrow: Weak high pressure will build over the forecast area and allow wind to diminish with seasonably cool temperatures remaining. Temperatures will dip below freezing tonight under clearing skies.
647 PM EST Tue Jan 9 2024 A strong low pressure system will exit the area this evening.
539 PM CST Tue Jan 9 2024 (This evening through Wednesday night) For portions of the northern Panhandles and the southwest Texas Panhandle, cold temperatures coupled with high albedo surfaces are getting these particular areas to struggle to get above freezing, along with a good snow pack as well.
The supporting upper level flow pattern shows a strong and broad trough with very cold air moving into our region from the north.
606 PM CST Tue Jan 9 2024 (This evening through Wednesday) Upper ridge moves overhead tonight as low-level flow shifts to the southwest, and as surface winds shift to the south.
1052 PM CST Tue Jan 9 2024 (This evening through Wednesday) Upper ridge moves overhead tonight as low-level flow shifts to the southwest, and as surface winds shift to the south.
A few snow showers remain across Southwest Idaho this evening in the wake of the earlier cold front. Temperatures remain in the upper 30s this evening in the lower valleys which will limit snow accumulations with the showers. The next cold front has reached the Pacific Northwest coast and will continue eastward into the Intermountain West reaching the forecast area by mid Wednesday morning. There will be a sharp gradient of snow amounts in the valley with the highest amounts (2-3") along the foothills to a dusting south along the Snake river. Strong winds of up to 60 MPH will be expected across the higher terrain through Wednesday morning for blizzard conditions especially on parts of US-20, Highway 93 and Highway 51.
WV imagery indicates weak ridging aloft transitioning east through the Central Plains. Near the surface, a weak lee side trough of low pressure is anchored in southeast Colorado. Much drier air in the lower and levels and associated with the system itself will hinder precip chances (<10%). A slight bump up in temperatures is likely today with westerly downsloping developing behind an advancing trough axis, helping nudge H85 temperatures up above 0C today. Even with widespread snowpack lingering, look for afternoon highs up into the 30s(F) across west central and central Kansas with the lower/mid 40s(F) in south central Kansas.
Currently at the surface, high pressure is building into Florida from the Gulf of Mexico in the wake of the recent cold front that is now pushing south of Florida.
1231 AM CST Wed Jan 10 2024 (Tonight through Wednesday night) A breezy but pleasant day is unfolding across the region with temperatures currently in the low to mid 60s. Clear skies and light winds will allow temperatures to fall into the low to mid 30s across the Coastal Plains. It's possible that the typical drainage areas across the Northern Coastal Plains experience brief freezing temperatures early Wednesday morning. Another pleasant day is in store tomorrow as high pressure remains in control.
100 AM EST Wed Jan 10 2024 A strong low pressure system will exit the area this evening.
1010 PM EST Tue Jan 9 2024 A strong low pressure system will exit the Ohio Valley to the northeast overnight.
These westerly breezes combined with sunny skies will lead to high temperatures about 10-15 degrees warmer than yesterday with 60s east of the escarpment and mostly 50s to lower 60s on the Caprock. Light winds and clear skies tonight will allow temperatures to drop back into the lower to mid 20s across the far southwest Texas Panhandle to the mid 30s across the southern Rolling Plains.
104 AM EST Wed Jan 10 2024 A strong low pressure system will exit the Ohio Valley to the northeast overnight.
- Light snow tonight/Wednesday night (inch type accumulations) preceding a cold front.
/15/ Tonight through tomorrow: Weak high pressure will build over the forecast area and allow wind to diminish with seasonably cool temperatures remaining. Temperatures will dip below freezing tonight under clearing skies.
Discussion: Weather impacts from the departing low pressure system will be winding down this morning. Snow showers associated with steep lapse rates under the mid/upper trough will continue to affect northern sections early this morning, with some heavier snow bursts at times in SW VA. Accumulations will be enhanced in the higher elevations and western facing slopes due to the 30-40 kt westerly flow at ridgetop level.
1043 PM CST Tue Jan 9 2024 (This afternoon through Wednesday night) We're seeing much quieter conditions today as the upper low responsible for yesterday's wind/dust storm is moved to the Eastern US and dry northwesterly flow aloft has moved in.
1038 PM CST Tue Jan 9 2024 (This evening through Wednesday night) For portions of the northern Panhandles and the southwest Texas Panhandle, cold temperatures coupled with high albedo surfaces are getting these particular areas to struggle to get above freezing, along with a good snow pack as well.
Surface analysis places a powerful area of low pressure centered over the Great Lakes region, with a cold front stretching southward through the Eastern Seaboard. Overnight, all available mesoscale guidance suggests the line of showers will push through the Lower Keys in the next hour or two, then the Middle Keys shortly after midnight, and then finally the Upper Keys shortly thereafter. A cold front will continue to push through the Florida Keys coastal waters from west to east overnight. From synopsis, breezes will shift rapidly around the compass over the next five days across the Keys coastal waters, as a series of low pressure systems and associated fronts slide east through the Gulf of Mexico. The first cold front will push through the Florida Keys coastal waters overnight, with winds backing to the northwest in its wake.
Another buckle in the trough arrives Wednesday morning, reinforcing the orographic flow for western Wyoming, and bringing another possible snow squall to Sweetwater County, albeit with a lower wind profile than today.
Morning lows will be in the 20s to lower 30s, with afternoon highs in the 50s and 60s (standard cooler north OK, warmer north TX gradient within that range).
505 AM CST Wed Jan 10 2024 (Today and tonight) Expect some warmer temperatures today as south to southwesterly winds continue to filter in some warmer air across much of West Central Texas.
951 AM EST Wed Jan 10 2024 Strong low pressure over Lake Huron will continue to move northeast into Quebec today. For tonight into Thursday, a weak low pressure system will move east across the Great Lakes.
The coldest air will likely arrive for the weekend with highs mainly below zero and lows in the teens/20s below zero along with dangerous wind chills Water vapor shows evolving western CONUS trof with main upper low over the Pac NW. Surface analysis place trof/front entering the far western Dakotas, with arctic boundary moving south into northern MT. Breezy west/northwest winds will develop behind the trof/cold front during the day with highs mainly in the 30s. Tonight, upper low currently over the Pac NW dives into WY by Thursday morning. Thursday, light snow will continue across our southern zones with upper low shifting southeast across the Central Rockies.
Current temperatures are cooler compared to 24 hours ago and range from the mid 30s to mid 40s in the Central Valley, and 20s to lower 30s over the mountains. The Winter Weather Advisory remains in effect for the Coast Range, Shasta County Mountains, and Burney Basin for 1-4 inches of snow above 2500 ft, and up to a foot at the higher peaks.
High temperatures today across South Florida are expected in the low to mid 70s. This will trigger cooler air advection, which brings down temps about 10 degrees from previous day. Morning lows on Thursday should drop into the low 50s around the Lake, and low to mid 60s elsewhere. By Thursday afternoon, weak high pressure over the state and the east GOMEX will continue to push eastward and offshore into the Atlantic.
This warming trend will continue into tomorrow, as the pressure gradient becomes tighter ahead of the approaching cold front. Our first event will move into the region by Thursday evening, as an negatively tilted upper trough ejects out of the SW CONUS into the Southern Plains. A strengthening low-level jet ahead of the trough will bring an influx of moisture into the region Thursday afternoon which will help increase sfc base instability, as dewpoints will climb to near 60 degrees.
This will allow high temperatures to climb to the mid 70s Today and low 80s Thursday as warmer air is advected into the region. With increasing cloud cover, less cooling is anticipated tonight, keeping low temperatures in the low to mid 50s for most of the area. The strongest gusts likely to occur over the Lower Rio Grande Valley. Pressure gradients are expected to tighten again Thursday afternoon ahead of an approaching cold front.
Radar continues to show light snow diminishing as the low pulls away from the region.
- Cold frontal passage this afternoon/evening with increasing winds (west-northwest gusts 20 to 35mph).
Thursday will be the nicest day we have in the forecast with plenty of sunshine and temperatures in the low to mid 50s.
(Today and tonight) Expect some warmer temperatures today as south to southwesterly winds continue to filter in some warmer air across much of West Central Texas.
This will trigger cooler air advection, which brings down temps about 10 degrees from previous day. Morning lows on Thursday should drop into the low 50s around the Lake, and low to mid 60s elsewhere. By Thursday afternoon, weak high pressure over the state and the east GOMEX will continue to push eastward and offshore into the Atlantic.
141 PM EST Wed Jan 10 2024 Winds will gradually diminish this afternoon as high pressure settles over the area along with dry weather through Thursday Night.
(Rest of today through Thursday) Quiet weather will continue this afternoon behind the passage of the cold front last night. High temperatures will be in the low to mid 70s with the exception of upper 60s right by Lake Okeechobee. Winds will shift out of the east and increase slightly as weak high pressure shifts offshore into the western Atlantic. Temperatures tonight will fall into the 50s near the lake and 60s elsewhere, with high temperatures tomorrow mostly in the low to mid 70s.
1248 PM EST Wed Jan 10 2024 Strong low pressure over Lake Huron will continue to move northeast into Quebec today. For tonight into Thursday, a weak low pressure system will move east across the Great Lakes.
Light southwest to south winds of 5 to 10 knots tonight become light southeasterly and increase to about 10 to 12 knots on Thursday (especially over the western half of the forecast area) as the ridging weakens and warmer and more moist air begins to advect into the area from out over the Gulf. Lows tonight will be a little warmer than last night, generally in the mid 30s over all of interior southeast MS and interior southwest AL, upper 30s along the I-10 corridor and then low to mid 40s along the immediate coast. Warmer by around 10 degrees or so for daytime highs on Thursday as well, with highs mainly in the mid 60s across the entire area.
(This evening through Thursday) Warm and dry conditions continue again on Thursday, as southwest winds increase ahead of an upper level trough approaching from the west.
Lee cyclogenesis will ramp up in southeast Colorado tomorrow as an upper level trough digs southeast across the Four Corners region. Wind speeds should decrease a bit after sunset but will likely remain breezy going into the overnight hours as a cold front approaches the forecast area and winds turn to the northwest.
1158 AM CST Wed Jan 10 2024 (Today and tonight) Expect some warmer temperatures today as south to southwesterly winds continue to filter in some warmer air across much of West Central Texas.
GOES 16 Visible satellite imagery shows a mid level cloud deck in the form of altostratus clouds which have lingered around since the cold front stalled over the southern Straits. The previous front that moved through last night is expected to lift back north as a warm front tonight through Thursday evening.
247 PM CST Wed Jan 10 2024 - Cold frontal passage this afternoon/evening with increasing winds (west-northwest gusts 20 to 35 mph).
Higher ratios expected should allow for 2-4 inches of snow across the far southwest, with the higher amounts near the Nebraska border.
304 PM EST Wed Jan 10 2024 Dry high pressure with near normal temps to overspread the area tonight into early Fri.
(This afternoon through Thursday) Already warmer than yesterday with a range of 50s area wide. There is a chance we may end up a little warmer than lower 60s with a southwest wind, but it will be mixing at the same time. Our first event will move into the region by Thursday evening, as an negatively tilted upper trough ejects out of the SW CONUS into the Southern Plains. A strengthening low-level jet ahead of the trough will bring an influx of moisture into the region Thursday afternoon which will help increase sfc base instability, as dewpoints will climb to near 60 degrees.
KBYX radar shows some light rain showers, mainly over the Straits of Florida continuing to move from southwest to northeast with the cold front just south of the Straits of Florida, but, to the north of Cuba. In the wake of the frontal passage overnight, temperatures are currently near 70 degrees with dew points much more comfortable in the lower 60s.

Tonight through Thursday A band of moderate to at times heavy snow along a cold front will progresses through central Nevada this evening moving into the southern portion of the county warning area by tonight. Stronger winds will push into central Nevada this evening as the cold front progresses southward.
Details: A strong cold front is set to enter northwest Oklahoma around 6pm tonight, pass through the OKC metro between 10pm and 2am, and clear the forecast area about 3 to 4 hours after that.
Surface analysis places an area of high pressure centered in the vicinity of the Florida Big Bend area.
The one thing of note is models are indicating high pressure building into the east and a weak wedge in the northeast Thursday night that ultimately should erode before any rain makes it to the northeast. Temps today to top out in the mid 40s to low 50s for much of the area before dipping down into the low to mid 30s tonight and then increasing into the mid to upper 50s tomorrow.

Forecast high temperatures are expected to be in the mid 50s to mid 60s Thursday before dropping into the upper 30s to lower 60s as the cold front moves across the state.
Jet support behind the leaf is enough to permit it to develop in a low pressure system in the lee of the Rockies.
Currently at the surface, high pressure holds over the Florida Peninsula while the recent frontal boundary is stalled out over the Straits of Florida. The stalled front will gradually lift north today and tonight as a warm front, with southerly low level flow leading to increasing atmospheric moisture and chances of showers.
1044 PM CST Wed Jan 10 2024 - Another round of snow is anticipated across much of the area with the heaviest amounts focused along the highway 36 corridor from Thursday afternoon through Friday morning.
533 AM CST Thu Jan 11 2024 (Today through Friday) Continue southerly flow will allow temperatures to climb to the low 80s this afternoon. A cold front extending to the southwest of this system looks to move across Texas, reaching Deep South Texas Thursday night. Cooler temperatures are also expected behind the front, with high temperatures Friday expected in the mid 60s to low 70s.
(Today and tonight) Expect warmer and mildly windy conditions today as southwesterly winds gradually increase ahead of an approaching upper-level trough to the northwest. There is also a small chance for some precipitation to fall across the far northern portions of the Big Country overnight tonight into Friday morning, which could fall in the form of light snow or flurries given the below freezing temperatures overnight tonight.
Strong winds expected tonight into Friday morning, Wind Expect warmer and mildly windy conditions today as southwesterly winds gradually increase ahead of an approaching upper-level trough to the northwest.

A cold front extending to the southwest of this system looks to move across Texas, reaching Deep South Texas Thursday night. Cooler temperatures are also expected behind the front, with high temperatures Friday expected in the mid 60s to low 70s.
Cold front Friday night. A high pressure system will provide dry weather through Friday morning. An strong inversion should protect counties away from the higher elevations and southeast flow downsloping until late in the day when the inversion erodes. Gradient winds in the higher elevations will not need mixing to make it to the ground and will be strong enough for a High Wind Warning. Frontal passage Friday evening should aid in mixing, and the potential for stronger winds to mix down in the lower elevations.
Temperatures along the Island Chain are hovering near 70 degrees with some locations in the lower 70s. The stationary front to the south of the Florida Keys will continue to slowly drift northward as a warm front through the evening hours. Friday and Friday night, went with a completely dry forecast due to stout southerly flow in the low to mid levels of 20 to 30 knots.
(This afternoon through Friday) As expected the warmer dew points arriving over the cool ground in E TX have a decent fog going with 1/2 to 1/4 mile restrictions from Lufkin to Nacogdoches, Jacksonville and Henderson. /24/ (Friday Night through Thursday) A dry and much cooler post-frontal airmass will settle across the region by Friday night.
Cold front Friday night. Cooler with snow showers over the weekend. A high pressure system will provide dry weather through Friday morning. An strong inversion should protect counties away from the higher elevations and southeast flow downsloping until late in the day when the inversion erodes.
