1223 PM EST Sun Dec 8 2024 - Warmer temperatures today and Monday.
South winds will usher in higher dewpoints and warmer temps today with highs forecast to climb into the lower to mid 60s across much of the region. 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.
- Cooler and continued dry on Monday. (This evening through Monday) Deep subsidence and sharp height rises were in full swing this afternoon on the heels of a mid and upper low now over NW Oklahoma. Healthy lee troughing meanwhile along the TX & NM border has amped up our WSW winds to near advisory levels at times on the Caprock, but these are slated to settle back by sunset as the boundary layer collapses.
337 PM 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. At the surface, High pressure off the Southeast U. Lows will range from the lower to middle 40s, except warmer near the immediate coast.
(This evening through Monday Night) Light rain prevails across much of the region this afternoon as a plume of southern stream moisture advects northeast above a departing cooler surface airmass. Prevailing south winds across the region have allowed for warmer dewpoints in the upper 40s to lower 50s areawide. Conditions forecast to gradually improve from the west on Monday as an upper-trough swings southeast into the Red River Valley of north Texas. High temperatures on Monday to average in the lower 60s across southeast Oklahoma to the mid 70s elsewhere. High pressure will rebuild across the region on Monday night with a reinforcement of cooler temperatures returning areawide.
310 PM EST Sun Dec 8 2024 Significant warming picks continues for the next couple of days ahead of a cold front.
1141 AM CST Sun Dec 8 2024 - Warmer conditions for today and Monday.
Mid afternoon satellite imagery continued to show the circulation around a closed low spinning over northern Oklahoma and southern Kansas. The closed low will continue tracking northeast tonight and open up over the mid Mississippi valley this evening. By morning the drier air brought into our CWA by the weakening upper level trough will have ended rain chances northwest of the Natchez Trace. Temperatures tonight and Monday will continue to be warmer than normal. Afternoon hi-res model guidance from both the GFS and the NAM continue to highlight a upper low pushing eastward across the Great Lakes Region.
(Tonight through Monday) Models depict a mid level trough/low complex deepening and migrating eastward across the SE CONUS, gradually pushing the dominant high eastward. As the high moves further east, winds over SoFlo will gradually veer to the SE by late Monday. This synoptic scenario will result in a brief warming trend, with Monday afternoon highs climbing back into the low 80s.
1125 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.
Strong southerly winds late tonight in the East Tennessee Mountains may gust up to 50 mph at the highest elevations with 35 to 40 mph gusts more widespread across the mountains and foothills. There will not be a surface front passage with this system, the trough will be triggering the rain without an immediate wind shift and cooldown like we get with a cold front passage. Once the trough passes in the morning, nearly zonal flow will move into the region. The highest elevations may see gusts up to 50 mph.
A mild and dry day will occur tomorrow ahead of a cold front.
522 PM CST Sun Dec 8 2024 - Cooler and continued dry on Monday.

259 PM MST Sun Dec 8 2024 - A cold front is on track to move across the area tomorrow bringing snow to the northern and central mountains and northern San Juans.
The bulk of the cold air looks to move in overnight and into Tuesday morning, so afternoon temps in the lower 50s is still plausible.
A dry cold front will bring gusty winds and colder temperatures to northern Arizona on Monday and Tuesday. Fair and warmer weather is expected again late in the week and into the weekend. Winds have increased today as the westerly flow is strengthening ahead of the trough approaching from the north.
131 AM CST Mon Dec 9 2024 - A cold front will bring a reinforcing shot of cold air for the back half of the week.
Aloft, the H500 trough continues to shift east of the state which will provide zonal flow across the area today. At the sfc, high pressure has shifted to the southeast with a pseudo warm front observed just north of KPBF this morning. Above normal temperatures will be seen across the state today before a cold front moves across the area from NW to SE tonight into early Tuesday morning.
146 AM MST Mon Dec 9 2024 - Cooler today with a gusty wind in some areas along with a scattering of snow showers.

As the high moves further east, winds over SoFlo will gradually veer to the SE by late Monday. This synoptic scenario will result in a brief warming trend, with Monday afternoon highs climbing back into the low 80s.
I have also gone ahead and introduced a Dense Fog Advisory for some of our northern zones, as this is where I have the highest confidence in reduced visibility. /44/ (This evening through Monday Night) Light rain prevails across much of the region this afternoon as a plume of southern stream moisture advects northeast above a departing cooler surface airmass. Prevailing south winds across the region have allowed for warmer dewpoints in the upper 40s to lower 50s areawide. Conditions forecast to gradually improve from the west on Monday as an upper-trough swings southeast into the Red River Valley of north Texas. High temperatures on Monday to average in the lower 60s across southeast Oklahoma to the mid 70s elsewhere. High pressure will rebuild across the region on Monday night with a reinforcement of cooler temperatures returning areawide.
(Today through Tuesday) Warm and pleasant weather across South Florida early this week as mid-level ridging builds across the FL Peninsula from over the Carribean. A relatively dry airmass and subsidence from the ridge will result in mostly clear skies and near zero rain chances. East-southeast winds in the low-levels will bring in a gradually warming airmass, with high temperatures in the upper 70s to low 80s today, and low to mid 80s on Tuesday.
1042 PM CST Sun Dec 8 2024 - Progressive cold front will bring strong wind gusts of 35 to 45 mph by early Monday, with gusts subsiding in the evening.
1113 PM CST Sun Dec 8 2024 - Warmer conditions for today and Monday. - Cold front will bring the potential for below freezing temperatures Tuesday night. (This evening through Monday) The upper low, which provided rain chances the past 2 days, is currently moving off to the east, allowing for much drier and warmer conditions today. Dry air is being brought in on the backside of the low, leading to mostly clear skies this afternoon. The exception to the west winds will be in the Big Country, where winds will turn more north/northwest as a cold front moves into West Central Texas. The cold front is expected to move into the northern Big Country in the early afternoon and push south as we go into the evening.
A ridge exteneded WSW across the Florida Peninsula and southern Gulf of Mexico. The Florida Keys and adjacent waters are located south of the ridge within an ENE to E flow of highly modified continental polar air with a long maritime trajectory. Currently, air temperatures in most Keys island communities are near or just above 70F, with dewpoint temperatures in the lower 60s. Winds are northeasterly along and north of the islands where sea surface temperatures are cooler, and mainly easterly south of the islands. Easterly flow transitioned to westerlies between about 10000-15000 feet elevation, consistent with the vertical tilt of the governing deep layer anticyclone.
High temperatures Monday and Tuesday will be some of the warmest this month so far, in the low to mid 80s. Especially along the nature coast where SST are cooler.
A low pressure system will bring more seasonal temperatures and elevated northerly winds to the region on Monday and Tuesday. Monday will be characterized by clear skies, slightly warmer-than-normal temperatures, and gusty north winds pushing southward through the forecast area. A change to windy and cooler weather is on the way Monday into Tuesday as the leading edge of a broad trough could be seen digging over the western states on satellite loops which was directing a swath of high clouds across our area today. Cooler air will spread across all zones by Tuesday bringing highs down several more degrees with readings in the mid to upper 50s for most desert zones. Low temperatures will dip into the mid 30s in the Las Vegas Valley early Tuesday morning, but winds should keep the boundary layer mixed and above freezing.
1053 PM CST Sun Dec 8 2024 Updated at 1050 PM CST Sun Dec 8 2024 - A strong cold front moves through the region late Monday into early Tuesday bringing colder temperatures for the middle of the coming week.
A few light showers are accompanying an upper level trough tracking into NE Oregon this evening. Above the inversion a reinforcing short wave trough from the northwest will renew snow showers in northern mountains this evening with accumulation up to two inches. Colder, drier northerly flow aloft will prevail Monday through Tuesday as the next upper ridge amplifies along the coast.
Clouds will slowly clear from west to east overnight tonight as a cold front moves through the CWA. The cloud cover and the initial lack of CAA behind the cold front will keep lows in the mid 30s to lower 40s. Modest CAA behind the cold front doesn't look to increase until tomorrow afternoon which will allow temperatures to still rise into the low to mid 50s. Tuesday, a broad, deep trough will move through the central CONUS.
Upper level trough axis continues to shift over the central U. In the wake of the cold front, temperatures will struggle to break freezing across much of the CWA, with our warmest forecast temperatures in the eastern Magic Valley and valleys south of the Snake Plain remaining below 40 degrees. High pressure will build in from the West on Tuesday with slight chances for snow showers continuing along the MT Divide and in the Island Park region.
1144 PM CST Sun Dec 8 2024 (Tonight through Monday night) The coastal trough has continued to shift northeastward throughout the day today resulting in a more southerly to southwesterly flow over South Texas. Although medium rain chances have persisted through the day (mainly due to isentropic lift), these are forecast to gradually diminish from west to east tonight into Monday as the aforementioned trough moves out of the area. Overnight lows tonight will range from the low 50s to low 60s, and in the mid 40s to upper 50s Monday night.
- A cold front will pass Tuesday, leading to a much cooler last half of the work week.
- Cooler Tuesday behind a front with dry conditions expected much of the coming week. Some of the hi-res models even show fog lingering into early afternoon in these areas, and given the low sun angle and lack of significant mixing, would not be surprised if this was the case.
126 AM EST Mon Dec 9 2024 High pressure will prevail early this week, before a cold front impacts the area midweek. High pressure will return for late week. At the sfc, high pressure extending across the Southeast United States from the western Atlantic will shift south and farther offshore with time. However, high pressure lingering in the vicinity will likely contribute to dry air in the low- mid lvls, which is depicted on the latest 00Z CHS sounding. The forecast area will be positioned on the backside of high pressure Monday into Tuesday, with a cold front advancing towards the region late. Temperatures will be warm, especially on Tuesday when highs are forecast to reach the low/mid 70s, even upper 70s in spots.
Updated at 240 AM CST Mon Dec 9 2024 - Widespread dense fog this morning - Cooler temperatures Tuesday behind a cold front.
Most areas will reach the lower 60s. Scattered showers will move across the area tonight through Tuesday as a couple of disturbances cross the area ahead of a cold front. Colder air will start to be felt later Tuesday after the cold front passes.
1113 PM CST Sun Dec 8 2024 (This evening through Tuesday) To begin the period, an upper level low is located just to the north and west of the state. This low will bring rain across much of the state this afternoon and into the evening hours. Cooler and more seasonable temperatures move in by Tuesday afternoon with highs in the lower 40s to upper 50s across the state.
A dry cold front will bring gusty winds and colder temperatures to northern Arizona today and Tuesday. A trough moves through Utah and Colorado today, nearly brushing Arizona to the north. Thus, dry conditions are expected given the lack of moisture with the assocaited cold front. The only real sensible weather impacts look to be cooler temperatures and breezier north/northeast winds. As the low propagates eastward, a tight pressure gradient remains in place over Arizona tonight, leading to increasing winds aloft.
Lingering showers continue to taper off this evening, particularly across central Puget Sound into the Cascades as an upper ridge builds offshore. Mostly dry and cool conditions will start off the week as high pressure builds overhead. Unsettled weather will return mid-week and beyond as troughing brings additional chances of precipitation.
- Mild and dry today ahead of a cold front later this evening.
Little to minor accumulations are expected from this across the lower elevations, with more moderate accumulations in the higher terrain. -Wilson /Issued 450 PM MST Sun Dec 8 2024/ - Meteorological Overview A Pacific cold front has moved through North-central, Central, and Southwestern Montana. This combined with an upper-level trough will bring mountain and mountain adjacent snow and cooler temperatures to the area today through Monday evening. Additionally due to the cold front, strong mid and upper-level flow, and a strong surface pressure gradient it will be windy across North-central Montana through this evening with wind speeds and gusts gradually dieing down from west to the east this afternoon through this evening. On Monday the upper-level trough remains over North-central, Central, and Southwestern Montana. On Tuesday an upper-level ridge builds back in over North-central, Central, and Southwestern Montana.
1102 PM 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. At the sfc, high pressure extending across the Southeast United States from the western Atlantic will shift south and farther offshore with time. However, high pressure lingering in the vicinity will likely contribute to dry air in the low- mid lvls, which is depicted on the latest 00Z CHS sounding. The forecast area will be positioned on the backside of high pressure Monday into Tuesday, with a cold front advancing towards the region late. Temperatures will be warm, especially on Tuesday when highs are forecast to reach the low/mid 70s, even upper 70s in spots.
A mild and dry day will occur tomorrow ahead of a cold front. Cooler weather will hang around through midweek and trend warmer by late week. Another cold front will move into the region this upcoming weekend with more rain possible.
1046 PM CST Sun Dec 8 2024 - Cooler and continued dry on Monday. - Strong cold front late Monday into Tuesday, but temperatures returning to near seasonal averages for the remainder of the week. (This evening through Monday) Deep subsidence and sharp height rises were in full swing this afternoon on the heels of a mid and upper low now over NW Oklahoma. Healthy lee troughing meanwhile along the TX & NM border has amped up our WSW winds to near advisory levels at times on the Caprock, but these are slated to settle back by sunset as the boundary layer collapses.
935 PM MST Sun Dec 8 2024 - A cold front is on track to move across the area tomorrow bringing snow to the northern and central mountains and northern San Juans. These clouds are in response to an approaching upper level trough and surface cold front. A few snow showers will begin over the northern mountains tonight with more pronounced snow falling along the cold front as it pushes through during the day Monday.
An upper level ridge of high pressure over the eastern Pacific Ocean extends north into Alaska. This will continue to move through the region overnight and exit on Monday as the ridge of high pressure moves inland.
- Cold front passes through Missouri tonight, dropping temperatures to below-normal ranges.
352 AM CST Mon Dec 9 2024 - Cold front today will lead to much more seasonal temperatures with north winds 20 to 30 mph. - Temperatures will remain around Climo for much of the week with highs generally 40s to lower 50s and lows in the lower to mid 20s. A Dense Fog Advisory will remain in effect through 9 AM CST, which is around the time that our next cold front will be gaining some forward progress, ushering in lower dewpoints. A positive-tilted large scale trough axis will swing through the Central Plains today and tonight without much fanfare as far as sensible weather is concerned for southwest Kansas, other than the aforementioned bump in north winds.
