- Temperatures fluctuate with the regular passing of cold fronts through the area. Once the front passes, high pressure will build into the region for several days. High pressure moves off to the east by late week as southerly flow returns to the area. Southwesterly winds are prevailing over the region ahead of an advancing cold front. The cold front is expected to move trough the region Sunday evening.
(Rest of today through Sunday) The decaying cold front has passed through South Florida as of this morning with winds having shifted out of the north. Drier and cooler air in the wake of the front will provide for a rain-free weekend. Maximum temperatures on Saturday will be a few degrees cooler ranging from the mid to upper 70s. Temperatures on Sunday will be a few degrees warmer than Saturday with highs in the upper 70s across most of the area.
249 PM CST Sat Dec 7 2024 - Rain and light freezing rain is expected tonight through Sunday morning, becoming mostly rain late Sunday morning. - Winter Weather Advisory for freezing rain tonight.
1117 AM CST Sat Dec 7 2024 (Today through Sunday Night) All is calm early this morning with high pressure centered over the area. With this warmer air and plenty of sunshine, temperatures will warm into the upper-40s to low-50s by this afternoon.
- Much warmer and breezier for Sunday. (This evening through Sunday) The final vestiges of rain were found departing the southern Rolling Plains at 1 PM well ahead of an upper low located west of El Paso. Water vapor imagery showed deeper subsidence overspreading the South Plains ahead of this low which will serve to scour out lingering stratus from W-E by this evening ahead of clearing skies tonight. Sunday features the upper low deepening while lifting across the region early in the morning. Deeper and drier SW flow trailing this low will support much warmer and breezier conditions by midday as mixing heights extend 3-4K feet and tap a lingering band of 20-30 knot winds around 800 mb.
The ridge of high pressure that had been in place for days is getting pushed to our south as an upper level trough digs into the PacNW. The aforementioned trough will push a cold front through the region late tonight and into the overnight hours which will bring a brief period of snow to just about everyone across eastern Idaho. Any accumulations of note will mainly be limited to the higher terrain of the central mountains and eastern highlands and even this is 1-3 for areas located between 6kft-7kft in elevation.
Increasing high clouds and a brief break in the winds for the lower Colorado River Valley can be expected Sunday.
- Strongest winds for this high wind event still expected overnight tonight. - Pacific cold front moves through tonight, bringing in colder air for Sunday. /Issued 316 PM MST Sat Dec 7 2024/ - Meteorological Overview: A Pacific cold front is approaching MT from the west. The cold front will move eastward across the CWA overnight tonight. Strong winds will accompany the cold front, with the strongest likely between Midnight and 6 AM Sunday morning.
A brief bout of light freezing rain will be possible early Sunday with very minimal impacts.
Additional showers could then develop from late tonight into and during Sunday morning from the Southern Edwards Plateau into the Hill Country and even perhaps into the northern areas of the I-35 corridor with the approach of the base of the parent upper low that becomes centered from the Texas panhandle into Oklahoma. The base of the upper level low will swing across the area through Sunday and this will allow for a drier northwesterly flow aloft to arrive on the backside of the trough. The low-level and surface flow turns west-southwesterly through Sunday as well, which weakens the isentropic forcing across the region. A milder but cool day is forecast for Sunday where daytime highs in the low to mid 60s should trend common.
916 PM EST Sat Dec 7 2024 High pressure south of the region will keep the area dry with a warming trend through the weekend.
A weather disturbance and accompanying cold front will push through northern Nevada tonight into early Sunday morning bringing some light snow to far northern Nevada, although little to no travel impacts are expected.
Clear skies and temperatures running MUCH warmer right now compared to last night. We are seeing southerly flow and that is bringing a big change in our temperatures, they are running 13-17 degrees warmer than yesterday this time. A short wave trough will be lifting out of the Four Corners region on Sunday.
427 PM MST Sat Dec 7 2024 Updated Aviation Temperatures will continue to remain above average through this weekend with highs in the low to mid 70s across the region.
636 PM EST Sat Dec 7 2024 High pressure south of the region will keep the area dry with a warming trend through the weekend.
(Tonight) Temperatures around 8 PM CST range from the lower 30s in the DeKalb Valley to the mid 40s at various locations, including portions of the Huntsville/Decatur metro area. High, thin cirrus clouds can be observed in satellite imagery streaming into the region from the SW, in advance of an upr trough moving eastward from the Southern Plains towards the southern/central Miss Valley. Any significant moisture advection and lift in advance of the upr trough will be confined largely to layers at or above 500mb overnight. Low temperatures are currently forecast to be in the 30s, but will probably remaining above freezing in most areas. The main exception will be in the often cooler DeKalb Valley (under similar conditions), where the latest temperature was at 31 degrees.
In addition, a longwave trough slowly inches towards the Mississippi Valley from near the Four Corners region. These conditions will warrant a warmer evening, so morning lows were increased slightly.
533 PM CST Sat Dec 7 2024 - Much warmer and breezier for Sunday. (This evening through Sunday) The final vestiges of rain were found departing the southern Rolling Plains at 1 PM well ahead of an upper low located west of El Paso. Water vapor imagery showed deeper subsidence overspreading the South Plains ahead of this low which will serve to scour out lingering stratus from W-E by this evening ahead of clearing skies tonight. Sunday features the upper low deepening while lifting across the region early in the morning.

503 PM MST Sat Dec 7 2024 Updated Aviation Temperatures will continue to remain above average through this weekend with highs in the low to mid 70s across the region.
- Temperatures fluctuate with the regular passing of cold fronts through the area. Once the front passes, high pressure will build into the region for several days. High pressure moves off to the east by late week as southerly flow returns to the area. Light southwesterly winds on Sunday will slowly veer through the day becoming northwest in central KS as we move toward 00Z with the arrival of a cold front.
550 PM CST Sat Dec 7 2024 - Rain and light freezing rain is expected tonight through Sunday morning, becoming mostly rain late Sunday morning. - Winter Weather Advisory for freezing rain tonight.
1247 AM EST Sun Dec 8 2024 High pressure south of the region will keep the area dry with a warming trend through the weekend.
352 AM EST Sun Dec 8 2024 High pressure will prevail early this week, before a cold front impacts the area midweek. High pressure will return for late week. Southern stream closed low is pressing into the western Texas/Oklahoma region with an upper jet axis arcing downstream through the Deep South/southeast U. Aforementioned southern stream closed low will eject through the Central Plains today before opening and lifting up through the lower Great Lakes region tonight. Meanwhile, lower level W/SW flow further develops, drawing warmer/higher dewpoint air into the region and daytime highs finally rebounding to around normal (middle 60s).
340 AM EST Sun Dec 8 2024 Significant warming picks up today and continues for the next couple of days ahead of a cold front.
1047 PM CST Sat Dec 7 2024 - Much warmer and breezier for Sunday.

Still on track for light Freeze and widespread Frost across inland areas this morning with lows in the lower 30s, while lows will be closer to 40F along the Atlantic Coast. High pressure remains over the region at the surface with light and variable winds at 5-10 mph, while high clouds will increase aloft through the afternoon hours, but likely not thick enough to prevent temps from getting back closer to normal values with highs in the mid/upper 60s SE GA and around 70F across NE FL. High pressure pushes off the Atlantic Coast at the surface and light south winds around 5 mph develop and will lead to milder overnight temps as high clouds continue to become more prevalent and will lead to partly to mostly cloudy skies towards morning.
1205 AM CST Sun Dec 8 2024 (Tonight) Temperatures around 8 PM CST range from the lower 30s in the DeKalb Valley to the mid 40s at various locations, including portions of the Huntsville/Decatur metro area.

1249 AM EST Sun Dec 8 2024 (Rest of today through Sunday) The decaying cold front has passed through South Florida as of this morning with winds having shifted out of the north. Drier and cooler air in the wake of the front will provide for a rain-free weekend. Maximum temperatures on Saturday will be a few degrees cooler ranging from the mid to upper 70s. Temperatures on Sunday will be a few degrees warmer than Saturday with highs in the upper 70s across most of the area.
1006 PM MST Sat Dec 7 2024 Updated Aviation Temperatures will continue to remain above average through this weekend with highs in the low to mid 70s across the region.
Water vapor imagery highlights a meandering upper-level low in the Southwest US, upstream from an amplifying and progressive mean layer ridge. Given the cooler SSTs north of the island chain and stronger gradient over the Straits, we assume values across the Gulf and Bayside range from 10 to 15 knots, while the Reef registers 13 to 19 knots at this hour. Temperatures range from the upper 60s to near 70 and dewpoints are in the lower 60s.
Satellite and radar imagery showing clouds and precipitation along the cold front as it advances through SE Oregon this evening. Webcams and weather observations are showing snow and freezing rain at lower elevations, with snow in the mountains. So far lower elevation temps have been fairly steady with some rise noted on the ODOT sites west of Ontario but still at or below freezing from Boise to Baker City. Higher elevation sites in SE Oregon have responded to the cold frontal passage with a wind shift to the NW and an increase in speed. Cold front bringing wintry mix of rain, snow, and freezing rain, moving through SW Idaho this eve through early morning. Cold front with freezing rain and snow will cause IFR/LIFR between Sun/04Z-08Z, then IFR/LIFR continuing in fog and low clouds behind front.
WEATHER PATTERN OVERVIEW: A strong storm system moving across the region today will be limited in moisture, but contain impactful winds through tonight behind a cold front. The High Wind Warning was kept the same in the west with highest winds being observed in the Little Rockies and messaging focused on blowing snow to the east. After the upper low moves to the east and winds diminish through the day on Monday, a northwest upper flow will prevail through midweek with seasonable temperatures and chances of light snow at times. DISCUSSION: As the wind increases today and bands of snow progress behind an incoming cold front this afternoon through tonight, ceilings will gradually lower to MVFR by 00Z with periods of IFR in the snow bands, primarily due to reduced visibility from falling/blowing snow.
Ssely winds will then develop for the afternoon as low pressure tracks from SD to srn MN with its warm front moving into far srn WI. The warm front will then shift nwd this evening as the low heads toward far nrn Lake MI, while a larger occluded low approaches from the nrn Great Plains. The low will drag its cold front through srn WI Mon AM and low level moisture may deepen enough for patchy drizzle over ern WI Sun nt.
939 AM EST Sun Dec 8 2024 Significant warming picks up today and continues for the next couple of days ahead of a cold front.
- Some light snow moves through Sunday night through Monday night as a cold front drops southward, bringing around 2 to 4 inches to the northern and central mountains.
As sfc ridging continues to shift away from the area and low level flow increase out of the S-SW, T/Td values have increased drastically over the past 24 hours. Some light rain has occurred overnight across generally the southern half of the state but as the H500 cyclone moves across northeast OK later today precip will increase from S-N across the state. The cold front lingering to the west of Arkansas will begin to move into the state Monday night.
A cold but moisture starved trough will move through the area through Sunday, bringing a chance of light snow to northern Utah and significantly weakening or mixing out inversions. High pressure will then return for the first part of the upcoming week.
Fog and freezing fog will be the main concerns for weather impacts over the next few days.
109 AM PST Sun Dec 8 2024 * A dry cold front will bring cooler temperatures for Monday with a period of gusty northeast to east ridge top winds.
This is due to prolonged southwesterly flow ahead of a closed mid-level trough shifting across the Texas Panhandle and Southern Great Plains. The approach of this troughing will boost southerly surface flow and warm air advection to allow 50 and 60-degree isodrosotherms to drift further north and across the I-20 corridor.
All this moisture will move up and over the lower thetaE air at the sfc providing more of an isentropic lifting situation with more of a tilt to the isentropic layers brought about by the layer lifting from the jet.
311 AM CST Sun Dec 8 2024 - Mild today with highs in the 50s to near 60 degrees! - Chance for patchy drizzle tonight, then slightly cooler on Monday.
The clockwise flow around the high will propel a northeasterly to easterly surface wind across the area today. As the high weakens and moves east into the Atlantic ahead of the next frontal boundary, the wind will become east-southeasterly. Overnight lows on Sunday night/Monday morning will be in the mid to upper 50s across inland Southwest Florida but the flow off the Atlantic will allow the eastern half of the peninsula to remain in the 60s except for a strip along the lake in the upper 50s and the immediate Atlantic coast in the lower 70s.
Surface analysis depicts high pressure centered over the Southeastern states, with the Keys remaining in a moderate pressure gradient to the south of this high. Aloft, mid level ridging is centered over the Gulf of Mexico, with an upstream low moving from New Mexico into the Texas panhandle. Dry weather will continue across the Keys today through Monday, with the dry and stable airmass preventing any shower development as mid level ridging aloft remains in control.
High pressure is building in today bringing breezy northerly winds and clearing skies.
541 AM EST Sun Dec 8 2024 - Warmer temperatures today and Monday.
A quick moving Pacific cold front has scoured out the majority of valley inversions across the Northern Rockies. Pockets of freezing drizzle/rain is still possible in isolated areas, particularly in the Seeley/Swan and Butte/Anaconda regions. A cooler air-mass will be in place at all levels, so the threat for freezing rain or drizzle will not be a concern with this system. The mountains and mountain pass could see anywhere from 3 inches on the low end, to 6 inches on the high end by Monday morning.
910 AM EST Sun Dec 8 2024 It was another chilly morning with lows dipping down into the low/mid 30s across the Nature Coast and 40s/50s elsewhere, but temperatures have started to recover quickly as high pressure to the north provides another sunny day ahead for the area. Highs today will be warmer than yesterday and should reach right around climatological normal values in the mid/upper 70s as the air mass continues to modify with it shifting into the western Atlantic.
- Dry cold frontal passage(s) will characterize the longer term forecast through the new week.
610 AM CST Sun Dec 8 2024 - Warmer conditions for today and Monday.
646 AM EST Sun Dec 8 2024 High pressure will prevail early this week, before a cold front impacts the area midweek. High pressure will return for late week. Southern stream closed low is pressing into the western Texas/Oklahoma region with an upper jet axis arcing downstream through the Deep South/southeast U. Aforementioned southern stream closed low will eject through the Central Plains today before opening and lifting up through the lower Great Lakes region tonight. Meanwhile, lower level W/SW flow further develops, drawing warmer/higher dewpoint air into the region and daytime highs finally rebounding to around normal (middle 60s). Warmer overnight temperatures spanning the 40s and close to normal readings. Additionally, a surface cold front will approach the region from the west. Ahead of the approaching cold front moisture will begin to increase.
620 AM EST Sun Dec 8 2024 Significant warming picks up today and continues for the next couple of days ahead of a cold front.
534 AM CST Sun Dec 8 2024 - Breezy and much warmer today. - A cold front on Monday will bring colder conditions mid-week but warming back up late week. (Today and tonight) The upper level low centered just to our west early this morning will accelerate northeastward today, shifting over our area and eventually being absorbed later tonight into a much broader longwave trough deepening over most of the northern CONUS. A cooler airmass will begin to filter in overnight, but with cold advection remaining fairly weak given only a small northerly wind component, relatively mild temperatures are still expected overnight with lows mainly in the mid to upper 30s.
519 AM CST Sun Dec 8 2024 - Mild today with highs in the 50s to near 60 degrees! - Chance for patchy drizzle tonight, then slightly cooler on Monday.
Quiet weather and slightly warmer than normal temperatures are on tap for the region today, with high clouds filtering through the area throughout the day.
315 PM EST Sun Dec 8 2024 After quiet weather tonight, a warm front will push through the area late Monday and Monday night with light snows and mixed precipitation.
Temperatures along the Island Chain are in the lower 70s with dew points in the lower 60s.
A wave of frontal low pressure was positioned off the southeast TX/southwest LA coast. The southern stream mid-level trough advances quickly east northeast out of the Plains States tonight. At same time, wave of surface frontal low pressure ejects quickly northeast over the Lower MS River Valley.
A quick moving Pacific cold front scoured out the majority of valley inversions across the Northern Rockies last night. In the wake of the cold front, snow showers are developing this afternoon. A cooler air mass is in place at all levels, so the threat for freezing rain or drizzle is not be a concern with this system. The mountains and mountain passes could see anywhere from 3 inches on the low end, to 6 inches on the high end, by Monday morning.
Meanwhile across the northern half things are clear for many areas outside of CU fields over the higher terrain and some lingering low stratus in the upper snake highlands and into Teton Valley. Hi-res models do show the potential for some snow showers throughout the day Monday, mainly across the eastern highlands but we can't rule out something potentially making it in to the lower valleys but not expecting any impactful accumulations. Highs Monday will be the coldest day we see over the week ahead with many areas hovering within a few degrees above or below freezing.
1242 PM EST Sun Dec 8 2024 Significant warming picks up today and continues for the next couple of days ahead of a cold front.
Temperatures along the Island Chain are in the mid 70s with dew points in the lower 60s. The aforementioned high pressure will continue to be the dominant weather feature through Monday night. The next item of interest will be an upper level trough currently over the Intermountain West. This trough is expected to dive (digging) southeastward over the course of the next few days before swinging from positively tilted to negatively tilted as it moves across the Southeast U.
1127 AM CST Sun Dec 8 2024 - Breezy and much warmer today. - A cold front on Monday will bring colder conditions mid-week but warming back up late week. (Today and tonight) The upper level low centered just to our west early this morning will accelerate northeastward today, shifting over our area and eventually being absorbed later tonight into a much broader longwave trough deepening over most of the northern CONUS.
