422 PM MST Tue Feb 7 2023 The northern portion of a splitting trough is moving over the Great Lakes region, while the southern low pressure system hangs out over AZ/NM. As the trough dives into the south central states Wednesday night, a reinforcing shot of cold air will sink into the northern plains, along with a second round of moisture.
The overall airmass doesn't change much, but mixing winds are expected to be lighter and thus temps will probably be a touch cooler vs today. For Wednesday night a mid level trof starts to dig into the Western High Plains from Colorado north into the Dakotas.
A mid-level high pressure from the Caribbean and a high surface pressure in portions of the Atlantic have resulted in fair weather conditions across the island chain. Current observations have temperatures in the lower 70s, and temperatures are forecast to fall a few more degrees over the next several hours. Tonight, expect mostly clear to partly cloudy skies, with temperatures in the lower 70s and east winds at 15 to 20 mph. Mostly sunny and tranquil weather conditions are expected to prevail throughout Key West again tomorrow due to the low and mid- level high pressures flexing their muscles over the region.
Quiet weather persists tonight with a weak disturbance and cold front clipping N.
Lighter winds are expected tonight with warmer temperatures on Wednesday.
546 PM PST Tue Feb 7 2023 Dry conditions are forecast to return this week due to high pressure, which may allow for fog and cold overnight lows to exist across the area. A low pressure system will pass over the forecast area this weekend; expect mainly lower temperatures and a chance for light precipitation. This morning, patchy dense fog and some freezing minimum temperatures were observed in the Central Valley. However, low temperatures will likely be slightly warmer for tonight into Wednesday morning. Temperature trends are up to ten degrees warmer than at this time yesterday. Daytime highs will further warm on Wednesday, as the high pressure ridge remains in place. A low pressure system will pass over portions of Central and Southern California over this weekend.
Deep-layer ridging continues to dominate the sensible weather for the Florida Keys this early February afternoon. The aforementioned ridging will continue to dictate our forecast through the rest of the work week.
As storms clear with the passage of the cold front, a seasonably cool and and dry airmass will become entrenched into the weekend.
Otherwise, patchy freezing fog is again expected tonight into Wed AM, followed by wind chills of 10 to 20 degF below zero Wed AM behind the cold front, especially north/east of Craters of the Moon.
Lighter winds expected tonight with warmer temperatures Wednesday.
A deep southerly flow and higher heights will make for a rather mild early November night, with lows by daybreak Wednesday cooling into the low/mid 50s.
633 PM EST Tue Feb 7 2023 (00Z TAFS) VFR conditions for all terminals this evening as a high pressure remains in control over the area. An upper-level ridge is centered just off the SWFL coast.
633 PM EST Tue Feb 7 2023 Temperatures will be above normal through the work week as an area of high pressure lingers for a few days.
Mountain and mountain pass snow accumulations remain the initial impact with this weather system since most of the valleys are mild and are expected to have downslope drying effects until the cold front passes. Model guidance continue to show a well organized cold frontal passage tonight.
408 PM MST Tue Feb 7 2023 Weak H5 ridging continues to sweep east across the region, which is keeping skies mostly sunny across the state. The next fast- moving trough will sweep through later tonight into Wednesday, bringing another round of snowfall to the western mountain. After this system moves through, a broad H5 ridge builds across the Rockies, keeping the storm track well to the north for the remainder of the week. A cutoff low drops into the Four Corners region over the weekend, with the associated trough moving across WY. Terminals will also see increased wind as a cold front pushes through with the snow.
544 PM CST Tue Feb 7 2023 (This evening through Wednesday night) Upper level low over southwest New Mexico will continue to lift out to the northeast through the Texas Panhandle on Wednesday. The low will then move away from the Panhandles Wednesday evening. A few rain and snow showers will be possible tonight on the north side of the low and then some rain and snow will be possible Wednesday across the central and eastern Panhandles in the wrap-around area of the low as it moves east.
Upper ridging is expected to develop over the western U. Look for west to northwest winds to ramp up on Wednesday with a cold frontal passage, ranging from 15 to 25 kts with gusts to 40 kts.
530 PM CST Tue Feb 7 2023 (This evening through Wednesday) The cold front has moved through the entire region this afternoon, with light isolated to scattered showers affecting parts of the area, mainly east of a Sweetwater to Sonora line. The upper level low currently over southwestern New Mexico will move east over El Paso tonight, keeping our area in southwest flow aloft, and maintain isentropic lift over the top of the shallow cold air mass. Then, as the mid/upper level trough pivots, and the axis moves east of the area during the afternoon, skies will clear out from west to east fairly quickly.
Quiet evening over west-central and southwest Florida as a high pressure remains in control of the weather pattern this week. Overnight lows will range from the lower 50s along the Nature Coast into the upper 50s to lower 60s in SWFL. Nearly everyone can expect to see high temperatures on Wednesday reach into the lower to middle 80s. An upper-level ridge is centered just off the SWFL coast.
639 PM EST Tue Feb 7 2023 High pressure will prevail through Wednesday night, then move offshore.
517 PM CST Tue Feb 7 2023 Summary: Quiet weather in the near term as upper level ridging moves in from the west.
High pressure wl continue with onshore flow around 10mph at the coast and increasing to around 10 to 15 mph from late morning through afternoon along the coast and around 8 to 12 mph inland. Partly sunny skies with slightly warmer conditions on Wednesday, with highs in the upper 70s along the coast and near 82 inland.
A very minor cold front is expected tonight with coastal drizzle at the most.
943 PM EST Tue Feb 7 2023 Temperatures will be above normal through the work week as an area of high pressure lingers for a few days.
1102 PM CST Tue Feb 7 2023 (Rest of tonight) Will continue to see an increase in clouds overnight as Gulf moisture increases ahead of an approaching cold front located over the southeastern Plains. Temperatures will remain well above normal thanks to the cloud cover and southerly flow, only dropping to the low to mid 50s.

1049 PM CST Tue Feb 7 2023 (This evening through Wednesday) A positively-tilted, mid/upper-level trough with a closed 500 mb cyclone was located over the Desert Southwest this afternoon where a plume of modified Pacific moisture continues to advect northeastward over north-central Mexico and into the CWA. The mid/upper-level trough is forecast to position over the TX/NM state line near sunrise, shunting the bulk of moist, isentropic ascent to near or east of the 100th meridian as the dry slot noses into the CWA. Clouds will erode from west-to-east, allowing for full insolation with temperatures nearly 10 deg F warmer than today amidst a light, westerly breeze at around 10-15 mph post-FROPA.
High pressure will keep dry weather for most of the area today.

233 AM EST Wed Feb 8 2023 High pressure will continue to head offshore, allowing for southerly winds and increasing cloud cover.
1024 PM MST Tue Feb 7 2023 Weak H5 ridging continues to sweep east across the region, which is keeping skies mostly sunny across the state. The next fast- moving trough will sweep through later tonight into Wednesday, bringing another round of snowfall to the western mountain. After this system moves through, a broad H5 ridge builds across the Rockies, keeping the storm track well to the north for the remainder of the week. A cutoff low drops into the Four Corners region over the weekend, with the associated trough moving across WY. With this system, a cold front will bring gusty winds as it passes, along with snow showers, which could be heavy at times. KBPI, KPNA, and KRKS also see the gusty winds as the cold front passes. A cold front pushes through Wednesday.
At 8 PM MST the upper front and most of the high clouds have already moved through our CWA, but the surface cold front and light pcpn were lagging behind, mainly in west-central Idaho.
254 AM CST Wed Feb 8 2023 Key Messages: -Warmer than average temperatures continue today.
Winds will subside a bit late tonight, falling below 10 knots in the lowest 2,000 feet. We will be warmer than normal tonight with lows in the 20s.
1021 PM EST Tue Feb 7 2023 High pressure will prevail through Wednesday night, then move offshore.
333 AM EST Wed Feb 8 2023 Weakening cold front brings rain showers into the area through tonight.

The low will then move away from the Panhandles Wednesday evening. A few rain and snow showers will be possible tonight on the north side of the low and then some rain and snow will be possible Wednesday across the central and eastern Panhandles in the wrap-around area of the low as it moves east.
1028 PM MST Tue Feb 7 2023 The northern portion of a splitting trough is moving over the Great Lakes region, while the southern low pressure system hangs out over AZ/NM. As the trough dives into the south central states Wednesday night, a reinforcing shot of cold air will sink into the northern plains, along with a second round of moisture.
Upper level ridging extends north-northwestward from the Bahamas, over Florida to the western Great Lakes.
838 AM EST Wed Feb 8 2023 High pressure will build from north of the region to the northeast Today.
419 AM EST Wed Feb 8 2023 The radar is quiet this morning with Upper Michigan under ridging. Meanwhile, a low pressure over the Southern Plains this evening lifts to near Chicago by Thursday morning before continuing through northern Lower MI Thursday. As this low moves through northern Lower MI Thursday, expect a secondary Clipper low to phase with it.
Cooler air to start the weekend. Temperatures will not be as warm today; however expect warmer than normal values. Winds today remain light through this evening as a ridge temporarily settles. A transition in the pattern begins overnight as a closed low races up from the southwestern states. A few higher isolated gusts are possible across northern Virginia counties overnight along the highest mountain peaks. Active weather expected on Thursday as low pressure lifts north into the Great Lakes region. The strong southerly flow associated with the system will allow for a nice warm up in temperatures, with high temperatures creeping close to 70 across the lowlands. Cold front associated with this system should be to the east of the CWA by Thursday evening, with drier weather taking hold, along with less windy conditions as the system pulls farther north and east.
534 AM CST Wed Feb 8 2023 (Now through Thursday) A cold front, currently moving into Zapata County, will pass through Deep South Texas this morning and is expected to push into the coastal waters around midday. In the wake of the front, cooler and drier air to filter into the region through the afternoon and into the evening.
look for warmer temperatures and light winds today. A dry cold front will push through the Four Corners on Thursday resulting in a return of colder temperatures and gusty northeast winds.
For the rest of today, high pressure will be in control, keeping the area dry. Temperatures should trend towards the lower 60s. East of the Cascades, we are looking at afternoon temps getting into the low 50s.
Low pressure was starting to develop in northeast TX, in response to energy ejecting out of the base of the New Mexico/western Texas upper low. Clouds will be on the increase ahead of the approaching low pressure system tonight, but a dry wedge in the lower levels will prevent any significant precipitation from developing before daybreak. Low temperatures should range from the middle 20s northwest to the lower 30s southeast. On Thursday, low pressure is expected to track from central IL to Lake Huron.
Widespread precipitation is occurring across the NR this early morning along a cold frontal passage. A secondary front will quickly follow which will result in gusty westerly winds and falling temperatures to freezing or below. Rain that has occurred all night switching to snow early this morning, combined with temperatures lowering to freezing, will result in slick driving conditions this morning, especially on side roads.
(Now through Thursday) A cold front, currently moving into Zapata County, will pass through Deep South Texas this morning and is expected to push into the coastal waters around midday. In the wake of the front, cooler and drier air to filter into the region through the afternoon and into the evening.
Weak mixing winds and increasing mid cloud cover this afternoon should lead to a bit cooler sfc temps today vs yesterday, despite similar warmth aloft. Still, readings should eventually climb above freezing leading to continued snow melt. However, a brief period of freezing rain cannot be ruled out as well.
(Today and tonight) Showers and a few storms expanded in coverage across West Central Texas since midnight, as lift from the upper low over New Mexico approaches.
Cold front will enter northeast Colorado late this afternoon and sweep through the forecast area 00-06z this evening.
Upper level ridging extends north-northwestward from the Bahamas, over Florida to the western Great Lakes. This high pressure remains the dominant weather feature through Thursday producing pleasant weather with rain-free conditions and above average temperatures across west central and southwest Florida.
- With warmer temperatures in the forecast, there is an elevated risk of ice jams in the Platte River. It will quickly drag a cold front across the area, resulting in gusty northwest winds and dropping temps.
521 AM CST Wed Feb 8 2023 (Today and tonight) Showers and a few storms expanded in coverage across West Central Texas since midnight, as lift from the upper low over New Mexico approaches.
540 AM CST Wed Feb 8 2023 Key Messages: -Warmer than average temperatures continue today. Heading into the evening hours, light precipitation is possible ahead of our next cold front. A very light wintry mix could be observed across the Highway 2 corridor and points south during the overnight period, with light snow then pushing into the area by sunrise. Temperatures today climb to a high in the lower to middle 30s by midday, then drop this afternoon and evening in response to the cold front. High temperatures in the lower to middle 20s occur around midnight Thursday, and will steadily fall through the day.
The approaching upper low has slowed down considerably from previously modeled solutions, and is likely to take a more southern track across our western north Texas counties by late afternoon or early evening before ejecting quickly northeast tonight. Temperatures aloft will drop as the upper low draws closer and thermal profiles should support brief periods of a rain/snow mix over western Oklahoma this morning.
Wetbulb temperatures will rise a bit above freezing in most locations. There has been a marked shift southeast with the track of the low overnight and forecasted snow amounts have been reduced quite a bit across southeastern MN into north central WI. A narrow band of snow may form along a cold front and could last an hour, maybe two in any given location.
widespread rain showers will continue to spread across the CWA as an upper low pressure.
Mostly rain is expected at the onset of the precipitation, but a question still exists of whether or not we see a mix of precip types or freezing rain. Strong warm air advection will support temps above freezing for most of the area, but there may be some wet-bulbing potential that could support a very brief period wintry mix for some areas at the onset of precipitation. For areas in the central interior part of the state that are always notoriously colder, there exists the potential for some freezing rain between 1am to 7am Thursday morning.
Temperatures cool behind a passing cold front. An upstream upper level trof enters the region, advecting moisture into the area. As this upper level trof digs into our area of responsibility (north central, central and southwest Montana), upper level winds become more north westerly. Additionally, a cooler airmass causes temperatures to dip. While the low elevation areas, generally, have a 25% (north central MT) to 70% (SW MT) chance of receiving a trace of snow, Most accumulating snowfall is reserved for mountainous areas. Once we get past today, an upper level ridge builds into the area, favoring dry conditions and rebounding temperatures for a few days. Southwesterly winds become northwesterly in association with a cold frontal passage.
625 AM EST Wed Feb 8 2023 Upper level ridging extends north-northwestward from the Bahamas, over Florida to the western Great Lakes. This high pressure remains the dominant weather feature through Thursday producing pleasant weather with rain-free conditions and above average temperatures across west central and southwest Florida.

Seas 3-4ft building to 5ft in the offshore waters by late afternoon, and 4-7ft overnight, with the higher seas confined to the offshore waters of Brevard and the Treasure Coast.
Upper ridging is expected to develop over the western U. LLWS is expected early this morning before west to northwest winds ramp up in the afternoon with a cold frontal passage.
Have upgraded the High Wind Watch to a Warning. The highest amounts will be on the west and northwest slopes of the mountains where 3 to 6 inches area possible.
An upper low over the Texas Panhandle will move quickly north and east throughout the day today. As the upper low becomes negatively tilted later tonight it will pull slightly unstable air north into west Tennessee that will bleed into our area after midnight. After showers push off the Plateau Thursday morning, we'll be dry and mild with highs reaching the low 60s that afternoon.
(Today and tonight) A closed upper low in eastern New Mexico with a positively tilted trough early this morning will pivot into West Texas by mid morning as it takes on more of a neutral tilt. Broad and moderate jet level winds on the downwind side of the trough axis will continue to bring large scale ascent through the morning hours with subsidence quickly sweeping overhead this afternoon. Moist isentropic ascent, mostly located off the caprock this morning, will also sweep eastward in the afternoon as the trough axis moves overhead. A barrier to measurable rainfall today will be the existing surface dew point depressions with a relatively dry atmosphere in the lowest 50-100mb or so. Skies are expected to clear out this afternoon but the close proximity of the upper trough will keep surface temperatures at or below seasonal averages.
656 AM EST Wed Feb 8 2023 The radar is quiet this morning with Upper Michigan under ridging. Meanwhile, a low pressure over the Southern Plains this evening lifts to near Chicago by Thursday morning before continuing through northern Lower MI Thursday. As this low moves through northern Lower MI Thursday, expect a secondary Clipper low to phase with it.
156 PM EST Wed Feb 8 2023 A warming trend continues into Thursday ahead of multiple low pressure systems moving through the region to end the week.
Several spots in our treed areas in the east have already hit the low 40s, so bumped up highs a bit into the mid to upper 40s. Key Messages: -Warmer than average temperatures continue today. Heading into the evening hours, light precipitation is possible ahead of our next cold front. A very light wintry mix could be observed across the Highway 2 corridor and points south during the overnight period, with light snow then pushing into the area by sunrise. Temperatures today climb to a high in the lower to middle 30s by midday, then drop this afternoon and evening in response to the cold front. High temperatures in the lower to middle 20s occur around midnight Thursday, and will steadily fall through the day.
- Period of freezing rain Interior Lower MI late tonight to Thursday morning With a warm front tracking into southern and central parts of the CWA late tonight into Thursday. Much of the region will be above freezing Thursday as the precipitation arrives. however our northeast zones will likely start out below freezing at the onset. Forecast soundings show a warm layer up around 850 mb with a shallow sub freezing layer near the ground. This should result in freezing rain. By 15z enough warming is forecast to occur the send surface temperatures above freezing. IFR and lowers conditions will arrive late tonight as a strengthening warm front approaches. KBTL and KJXN was the warm front pushes just north of those sites late Thursday morning. Most indications are the surface temperatures will be several degrees above freezing as the precipitation moves in.
