(Today through Saturday afternoon) While everyone was sleeping off a Thanksgiving dinner that couldn't be beat, a cold front was slowly drifting across southeast New Mexico and the Permian Basin. Areas to the north will stay cooler in the 40s to mid 50s with areas to the south remaining in the 60s to near 70F along the Rio Grande. Heading into tonight, the same cold front lifts back north of the Permian Basin keeping lows in the upper 30s to 40s for most.
1100 PM CST Thu Nov 23 2023 - Dry weather forecast today with progressively cooler temperatures into the weekend.
Area under cold air advection with cold front now well south and high pressure building in from the northwest.
Greatest accumulating snowfall risk is across the MO River Valley into the Highway 20 corridor. Wind should stay less than 20 mph keeping travel impacts minimal as high temperatures rise toward freezing Saturday.
Temps will be a bit cooler for today compared to yesterday as a result. with some small moisture return expected Sat night ahead of an approaching cold front from the NW.
1221 AM EST Fri Nov 24 2023 A weak cold front tonight will usher in slightly colder air for Friday into the upcoming weekend.
1224 AM EST Fri Nov 24 2023 An upper low across the Lower Mississippi Valley is bringing an increase in high clouds to the region tonight and Friday, but dry air and high pressure at the surface will mitigate any precipitation chances. Dry tonight and Friday with slightly warmer temperatures. Discussion: Weak flow aloft is present across the region while an upper low is moving across south Texas. Upper level moisture/cloud cover is moving northward from this low and is beginning to move into far southern portions of the area. High pressure at the surface will keep conditions calm. Clouds should begin to clear our by Friday morning with more sunshine expected and slightly warmer temperatures.
1016 PM CST Thu Nov 23 2023 (The rest of tonight) Skies are generally clear across the area this evening, but high and mid clouds associated with approaching upper trough will be on the increase tonight. A shallow cold front continues to slowly push across northeast OK this evening with a slight increase in north winds. Further west, however, a closed low will amplify across the Great Basin which will then move towards the area Saturday. High pressure banking up against the Rockies will send cold air south into northwest OK and KS during the day Saturday. Meanwhile, the closed low will eject eastwards across KS, opening up as it does so, eventually being absorbed by a larger trough across the upper midwest.
200 AM CST Fri Nov 24 2023 * Chilly day today behind another cold front.
1028 PM CST Thu Nov 23 2023 (Tonight through Friday night) For tonight, with the upper low moving out of the area, clouds will thin out if not disappear. High pressure will shift east across the North Gulf Coast on Friday, causing light winds to steady up from the northeast and east. As winds start to veer, a weak coastal trough will take the place of the front and will stretch north along the North Mexican and Lower Texas Coastlines.
Moderate high pressure blankets the southeastern United States and Gulf of Mexico. The combination of earlier day time heating and the Keys being on the far southeastern fringes of the high has resulted in winds becoming light and mostly northeasterly. However, below this is a good chunk of drier air above a shallow moist but cooler zone near the surface. As a result, expect overnight lows to settle broadly in the lower 70s with dew points around 70. A ridge across the southeastern United States will maintain light mostly northeasterly breezes on Keys waters through the overnight period.
Cloud cover will keep temps warmer tonight compared to this morning with lows in the upper 40s and low 50s inland with mid 50s at the coast. pdf Weak high pressure will be over the region this afternoon and evening, as moisture begins to stream northeast across area from a weak wave over the Gulf. These showers are expected to be fairly light, as the low levels are dry. The cloud cover will keep it from getting quite as cool Tonight, with lows generally in the lower to mid 50s. Drier weather conditions will return on Saturday as influence from high pressure ridging becomes the dominant weather feature. Daily high temperatures for the end of the week will be in the mid to upper 60s with temperatures rising into the lower 70s over northeast Florida over the weekend.
A strong cold front will be knocking on our northern doorstep by early morning. This cold front will continue to slowly sag south through the area through the afternoon hours. A passing weak disturbance is expected to result in a weak area of low pressure centered over the region. This low pressure may act to slow the cold front's advance through the region, likely stalling the front just north of the Pecos. Areas to the south remain pleasant with temperatures in the 60s and 70s ahead of the cold front. By Saturday morning, a large upper-low is forecast to be centered over the Four Corners and as this features begins to move east, aides in pushing the cold front through the remainder of the area.
1026 PM CST Thu Nov 23 2023 (Tonight through Friday night) This evening will be pleasantly cool and drying off with the moisture from a weak upper low pulling away into East TX. A longer period of sunshine for Friday will lead to a warmer afternoon for most of the area.
(The rest of tonight) Skies are generally clear across the area this evening, but high and mid clouds associated with approaching upper trough will be on the increase tonight. A shallow cold front continues to slowly push across northeast OK this evening with a slight increase in north winds. Further west, however, a closed low will amplify across the Great Basin which will then move towards the area Saturday. High pressure banking up against the Rockies will send cold air south into northwest OK and KS during the day Saturday. Meanwhile, the closed low will eject eastwards across KS, opening up as it does so, eventually being absorbed by a larger trough across the upper midwest.
236 AM PST Fri Nov 24 2023 A weak disturbance swirling around a large low pressure center over the Great Basin, will continue the cooler weather, and bring some scattered showers through tonight.
(Today and tonight) A weak cold front will track through the northern half of our area today, setting the stage for a cooler air mass to prevail over the area. Temperatures this afternoon are expected to warm into the 60s, then begin to drop into the lower to mid 40s by later tonight into early Saturday morning.
Drier air will filter into the region as the high builds into the area, with skies clearing this afternoon. Temps will rise into the lower to mid 60s, and then plummet into the upper 30s to lower 40s overnight as radiational cooling sets in.
Rain and snow continue in the morning as the low pressure system slowly moves east and is expected to diminish in the afternoon to evening hours. High pressure system is expected to move in over the weekend, bringing in calmer skies and warmer temperatures. Today through Saturday Today, the storm front is moving eastbound out of the state, however, latest model trend are showing that the back half of the low pressure system is expected to bring more rain and snow for northern Nevada this morning. Saturday, drier weather is expected as a high pressure system begins to move its way in over the western U. Temperatures will see a slight warming with highs in the 30s, however lows will be slightly cooler yet still be in the single digits to teens.
Discussion: Upper trough has been deepening into a closed low over the western CONUS, currently centered over NV/UT/ID as of 0930Z.
453 AM MST Fri Nov 24 2023 Latest 500 mb analysis shows an upper low centered over the Intermountain West - at the border of UT/NV/ID. As upper ridging nudges east, it will allow snow to our west to enter the area. The upper low will slowly progress east-southeastward over Utah today. The upper level low nearing the area Saturday morning will reinvigorate snow chances. Snow intensity also may increase for portions of the Tri-State Area, dependent upon position of the low. Snow chances will begin to wane from west to east as we head into Saturday evening with drier air on the backside of the low. Saturday night the upper trough axis will push east of the area with clearing skies behind it.
Thermal profiles support mostly snow across the forecast area, although warmer temperatures should support mostly rain over far southeast Kansas. As the previous forecaster mentioned, there is a chance for some mixed precipitation in the form of snow, sleet, and freezing rain over mainly south-central KS, southern portions of central KS, and also the Flint Hills, where a 1-2C warm nose aloft may exist for a time per deterministic consensus.
424 AM CST Fri Nov 24 2023 (Issued 405 AM CST Fri Nov 24 2023) Today through Saturday: Quiet, mostly sunny, cold and dry as a strong high pressure works its way southeast over the Upper Midwest today through Saturday. Winds may be breezy to start the day, but northwest winds should ease this afternoon and into the evening as the center of the high pressure moves closer. Temperatures will be a few degrees above freezing on Saturday with continued dry conditions under cloudier skies during the daytime hours.
416 AM CST Fri Nov 24 2023 Today and Tonight: A compact upper-level low pressure system seen spinning over the MS/AL border early this morning will quickly sweep east of our forecast area today. In the wake of these disturbances, a cold front will dip into the area. Short wave ridging at the start will keep things dry Saturday.
540 AM CST Fri Nov 24 2023 (Today through Saturday) A cold front is draped across Oklahoma and Kentucky, then northeastward through New York this morning. There is a small chance of seeing some light rain/sprinkles across the area through the first half of the morning, as an upper low moves through. The cold front will begin to push into the area by midday and then generally be positioned south of the Interstate 85 corridor by sunset. Generally we expect just clouds to accompany this front as the airmass is dry on the backside of the upper low that is swinging through right now. As we move through the day Saturday, high pressure will be in control. Look for the high pressure to slide east and will increase the easterly flow across the area.
An area of cloudiness and showers has been gradually working northward through the Straits of Florida to the south of the Lower Keys during the late night hours, while mainly dry conditions continue along the Keys island chain. It has been another warm and humid night, with temperatures hovering in the mid 70s and dewpoints in the lower 70s. Surface analysis depicts a stalled frontal boundary just south of the island chain, with weak high pressure over the Lower Mississippi Valley. Rain chances will gradually decrease tonight and Saturday as the frontal boundary dissipates and the low level flow becomes more uniform from the east.
Clouds increase further on Saturday due to the combination of rising LL moisture thanks to a developing coastal trough and the introduction of weak disturbances embedded in the flow aloft.
(Today through Saturday) Clouds will be slow to move out today but we should get enough sun to warm our high temps into the low to mid 60s. Clearing late today will set up a very good radiational cooling night causing lows to fall well into the lower 40s and a few upper 30s look to be possible over the northern most portions of SW Mississippi. No freezing issues yet but that can't be much farther down the road.

633 AM CST Fri Nov 24 2023 Today and Tonight: A compact upper-level low pressure system seen spinning over the MS/AL border early this morning will quickly sweep east of our forecast area today. In the wake of these disturbances, a cold front will dip into the area. Short wave ridging at the start will keep things dry Saturday.
A closed low is moving into the Great Basin and will be our main weather maker over the next couple of days. Tonight into Saturday the low begins to open up and move south into the Four Corners region. Showers will dissipate Saturday afternoon as the low moves off to the east. Temperatures will be much cooler with highs in the low to mid 60s from Tucson westward and upper 50s to low 60s east of Tucson.
Taking a look at the water vapor satellite imagery, an impressive mid- latitude cyclone is visible as it is draped across the Intermountain West. Additionally, the stacked upper level low at H7 and H5 levels in the atmosphere are analyzed across far northeastern UT and western WY. Daytime highs will struggle to get out of the single digits to teens today, and overnight lows in the lower single digits to negative single digits will keep similar outdoor weather conditions through Saturday morning.
(Today through Saturday) A cold front is draped across Oklahoma and Kentucky, then northeastward through New York this morning. There is a small chance of seeing some light rain/sprinkles across the area through the first half of the morning, as an upper low moves through. The cold front will begin to push into the area by midday and then generally be positioned south of the Interstate 85 corridor by sunset. Generally we expect just clouds to accompany this front as the airmass is dry on the backside of the upper low that is swinging through right now. As we move through the day Saturday, high pressure will be in control. Look for the high pressure to slide east and will increase the easterly flow across the area.
Dry and cool conditions are forecast to continue as upper level high pressure remains in place.
You can see the upper low (around 500 mb) nicely in satellite imagery moving northeast and approaching the Columbus, MS radar. Models move this upper low more to the east-northeast towards daybreak and weaken it at the same time and it gets absorbed into a frontal boundary stretching from northwestern Kentucky through northern Arkansas that is moving southeast. Given the depth of dry air aloft, not expecting much of a chance of any precipitation as this upper low moves through the area through daybreak.
138 AM PST Fri Nov 24 2023 Gusty north to east winds persist through today alongside cooler temperatures. Troughing prevails over the Great Basin region, leaving interior NorCal underneath stout north-northwesterly flow aloft. Winds will begin to lighten late Friday into Saturday, but will still remain breezy as the Great Basin trough only gradually exits the region.
A ridge is building over the region today with a dry air mass in place. Indeed, this morning and the next few mornings will see the coldest temperatures so far this winter as temperatures drop into the low teens and into the single digits in some places.
(Today and tonight) Clear skies in a dry post-frontal airmass this morning with N/NE winds gusting 30-40 mph in the higher elevations of the North Bay.

(Tonight through Saturday night) A broad upper level trough covers the western US this afternoon with west-southwesterly flow over Texas. The low level flow is from the south to southeast. Temperatures today are five to ten degrees warmer today than yesterday. At the surface an area of low pressure will develop along the South Texas coast keeping winds across our CWA from the east. Temperatures tonight will be warmer with lows in the 40s and 50s. Temperatures will be cooler due to cloudy skies and isolated rain. Saturday night a cold front will move through Central Texas and showers will develop ahead of the front and move into our eastern counties.
1120 AM CST Fri Nov 24 2023 (Today and tonight) A weak cold front will track through the northern half of our area today, setting the stage for a cooler air mass to prevail over the area. Temperatures this afternoon are expected to warm into the 60s, then begin to drop into the lower to mid 40s by later tonight into early Saturday morning.
(This afternoon through Saturday Night) It's not a bad Black Friday across the area with some scattered high clouds filtering the sunlight and temperatures in the low to mid 50s. Clouds will start building in during the afternoon ahead of trough that will approach the area late Saturday night.
Saturday will see a day of transition as aforementioned upper low starts to open up and move east, switching our flow to west/northwest ahead of an approaching clipper system that will slide through the area Saturday night.
Shallow cold front moving slowly south thru the region today will begin to hang up tonight in the terrain to the east and south.
Winds will become easterly or northeasterly behind the front, with slightly cooler temperatures expected this afternoon relative to yesterday. High temperatures will peak mostly in the low 60s with a few spots in North Texas remaining in the upper 50s. As a result, temperatures will be just a touch cooler for some areas tomorrow, with afternoon highs in the mid 50s to mid 60s.
We will allow the highlights to expire at 16z as originally planned with light snowfall continuing into the early afternoon hours across the south. Huston Our Thanksgiving Day winter weather system is slowly winding down as the low moves into northern Utah. Highs regionwide will be within a few degrees of the freezing mark.
1113 AM CST Fri Nov 24 2023 * Chilly day today behind another cold front.
However, high pressure will build into the region Saturday.
(This evening through Saturday) Weak cold front still sagging slowly across the Big COuntry south of I-20 this afternoon, although with very little difference in temperatures across the boundary. It is cooler farther north across Oklahoma and the Panhandle and with a little better cold advection overnight, some of that colder air mass will settle into the area for Saturday. Upper level trough to the west begins to approach the Southern Plains by afternoon, with lift starting to generate a few showers by mid to late afternoon, both across the northern Big Country and east where the moisture will be better across the Heartland.
pdf Wave of low pressure will continue to track off to the east northeast through Tonight, with high pressure building from the north northwest. Enough troughiness continues in upper pattern to justify keeping a few showers in the forecast through the night, but this chance will be low.
(This evening through Saturday Night) High pressure will rebuild behind a weak frontal boundary that is forecast to move through the region later today. North winds behind the front will usher in a reinforcement of cooler air with overnight lows forecast to fall into the mid to upper 30s. High temperatures on Saturday will average in the lower 60s. The warming trend will also be aided by increasing cloud-cover ahead of an approaching upper-trough and surface front. Otherwise, showers will increase in coverage late Saturday night as the cold front pushes through the region.
