538 AM CST Fri Feb 7 2025 Today and Tonight: Early morning surface analysis still had a ridge nosing west over the northern Gulf from a high centered over the Florida peninsula and a cold front from just north of Columbus to just south of Greenville. The cold front was dropping temperatures into the middle 50s but this cold front is expected to stall south of Highway 82 later this morning and then return north of our CWA this afternoon.
As the cold front departs the rain has tapered off.
- Freezing drizzle with a light glaze of accumulation possible tonight into Saturday morning mainly along and north of Highway 36.
Updated at 321 AM CST Fri Feb 7 2025 - Another reinforcing cold front arrives Saturday.
WEATHER PATTERN OVERVIEW: Nearly zonal flow persists over the CONUS with a weak trough off the Pacific Northwest this morning. Given the low probability for more than 6 inches of snow along with the localized nature to far southern Petroleum county, will opt for maintaining the advisory.
(Now through Saturday) A closed upper low meanders around over the western Gulf into the weekend. Southerly to southwest low level flow continues over the Lower Mississippi River Valley and southeast, keeping the boundary layer moist.

419 AM CST Fri Feb 7 2025 Today and Tonight: Early morning surface analysis still had a ridge nosing west over the northern Gulf from a high centered over the Florida peninsula and a cold front from just north of Columbus to just south of Greenville. The cold front was dropping temperatures into the middle 50s but this cold front is expected to stall south of Highway 82 later this morning and then return north of our CWA this afternoon.
Another warm, dry, and breezy desert day is in store for southeast Arizona as the subtropical ridge remains amplified over north-central Mexico. The ridge will be supportive of afternoon high temperatures topping out in the 70s to low 80s across the area which is about 5 to 15 degrees above normal for early February depending on location.
A warm front is moving north through the region during the predawn hours and will continue to lift into Montana. We are awaiting a cold front which should race through east Idaho this morning. With the cold front expected to arrive a little earlier than we anticipated yesterday, the widespread snow will likely come to an end this afternoon. Additional snowfall amounts after 12z are 3 to 6 inches from Hailey to Stanley with up to 10 inches near ridgetops; 1 to 3 inches around Challis, Mackay, and Arco; 3 to 6 inches for the Island Park/Driggs area with up to 10 inches on the ridges; and 1 to 4 inches for the southeast highlands with up to 8 inches near ridges.

Freezing temperatures possible for inland valleys. Some lingering cloudiness is likely for areas south of the SF Bay as a secondary weak low moves ashore along with a lagging cold front aloft. As skies clear tonight and a cold airmass settles in, Saturday morning marks the first of several mornings with cold overnight lows nearing the freezing mark for many. Black ice on roadways may be a possibility Saturday morning for areas that do see temps near freezing, especially in areas that received rainfall most recently. However, these locations will still be in the lower 40s (official forecast low at SF tonight is 41). Locations most likely to see temps hit the freezing mark will be inland valleys of the North Bay, the southern Salinas Valley, and southern interior San Benito County.
While the prevailing wind direction has remained easterly, there has been a northeasterly component in the lower levels as the heart of our dominating high pressure has shifted slightly. The ridging pattern that has helped to keep our weather mostly quiet will continue, and will help to deflect any approaching fronts from our area. A series of high pressure systems will continue to push across the eastern United States and into the western North Atlantic during the next several days.
There are only so many ways to say how beautiful the weather is outside! Our KBYX radar has been following a handful of isolated showers in the distant westernmost portion of the Florida Straits, but we also noticed that the radar is highlighting the low cumulus field that has developed over the southern tip of the peninsula. A series of high pressure systems will continue to push across the eastern United States and into the western North Atlantic during the next several days.
Overnight lows will be warm, only falling into the lower to middle 60's for most locations.

Tight gradients between this wave and the ridge to the south has brought another breezy/windy day to the area today. The s/wv has also brought some marine layer moisture into western and central Arizona, where dew points currently range from the lower 30s to upper 40s. This moisture may advect into the higher terrain tonight, where it will trap below a subsidence inversion at 700mb. This trough lifts away from the area on Saturday, allowing above normal hghts to remain in place over Arizona.
CAMs continue to show the higher mesoscale banding remaining along and south of the I-94 corridor through the evening hours and into tonight, with areas seeing up to an inch per hour for snowfall rates. Currently it is beginning to snow along the SD/ND border as a sfc cyclone deepens in MT and works east along a baroclinic zone with reports already topping 4-6" in western Bismarck where conditions have seemingly over performed what was expected to this point. North of this corridor a deformation band will setup at 850-700mb blocking northward moisture and capping snowfall amounts further north.
356 PM CST Fri Feb 7 2025 - Freezing fog and freezing drizzle may impact portions of the area tonight into early Saturday night.
Much cooler and drier air will begin to advect across the area today. The ECMWF EFI is indicating high confidence in very cold conditions with the potential (20% chance) of some record breaking cooler temperatures some nights along the coast. Lows along the coast will most likely be just above freezing with lows below 30 in much of the interior, except in valleys where fog may help keep warmer conditions.

- Periodic snow showers will be possible over western WY with the bulk of the snow remaining in the higher elevations. A cold front moved across the state during the day which ushered in chilly temperatures to much of the state. Highs today are forecast to be below normal with many seeing temperatures in the low to upper 20s. Temperatures along the Wind Corridor from Casper to Rock Springs may see milder highs in the low to mid 30s. Western basins may see a brief light snow shower but the bulk of the snowfall is expected to remain among the higher elevations. Snow accumulations will be very minimal with the highest peaks only seeing at most 1 to 2 inches.
222 AM CST Sat Feb 8 2025 - A wintry mix of freezing drizzle and snow is expected this morning into afternoon.
The high hes put most of the precipitation along the coast, western Josephine County and north of the Umpqua Divide.
In fact we had a cloud line develop across the Lower and Middle Keys, which quickly eroded shortly after 3 pm. Meanwhile, a ridge remains fairly flattened across the Gulf and south central Florida. Temperatures are currently in the mid 70s and we're on track to reach the lower 70s. Deeply entrenched dry air and robust ridging will keep dry weather through the overnight. A series of high pressure systems will continue to push across the eastern United States and into the western North Atlantic during the next several days.
This morning a warm front is lifting north through the area and will bring us mild temperatures today in the 50s and 60s. The low then tracks through the area and drags a cold front with it bringing our temperatures down into the upper 20s to lower 30s tonight.
Did have to make some adjustments to min temps, mainly to lower temps N of the front as the cooler air has been more stubborn to erode/lift N.

Discussion: A few light and isolated showers are expected this morning across northeast TN and southwest VA near the vicinity of a warm front. Behind this warm front temperatures will surge to near record highs this afternoon, with most areas reaching into the upper 60s to low 70s. Higher gusts from 30 to 40 mph are expected across the highest elevations of the east TN mountains later this evening and overnight. Tonight, a cold front moves in from the west and brings higher chances of widespread showers across the area.
304 AM CST Sat Feb 8 2025 - A brief period of light freezing rain may create slippery travel conditions along/north of a Macomb to Danville line this morning.
- Periodic snow showers will be possible over western WY with the bulk of the snow remaining in the higher elevations.
We will maintain a dry forecast through the day, with afternoon highs in the low to mid 70s.
529 AM CST Sat Feb 8 2025 (Today through Sunday) The 500 mb cut-off low will continue to linger over the western Gulf through late tonight. This mid to upper level low will slowly drift eastward and weakens on Sunday. At the surface, expect light to moderate southerly to southeasterly winds to continue, becoming gusty this afternoon and Sunday afternoon as broad high pressure across the Gulf interacts with low pressure across the Southern Plains. High temperatures today and Sunday will range from the 70s at the beaches, mid to upper 80s across the coastal counties and the lower 90s across the western portions of the CWA.
Some isolated flurries are possible through the morning underneath the low stratus hanging around, but as clouds diminish from north to south, this activity will end. Ahead of this trough base, light snow persists across much of south central and southeast North Dakota, with up to another inch of accumulation possible in the southern James River Valley, and lesser amounts elsewhere.
Isolated snow showers and steady northwest winds in the wake of a cold front are expected today.
The highest totals will be over east central Wisconsin, across the northern portions of Marquette, Green Lake, Fond du Lac, and Sheboygan Counties, where 2-3 inches of snow is expected. South of there, intermittent cloud ice will result in occasional periods of freezing drizzle along with light snow, but overall meager amounts of moisture and temperatures right around freezing will keep snow and ice amounts low. Highs today will be around 30, with a few locations over far southeastern Wisconsin possibly jumping above freezing for a short time. Skies are expected to clear through the morning on Sunday, as high pressure builds into the area. Highs will be in the low to mid 20s north, and mid to upper 20s south.
449 AM CST Sat Feb 8 2025 - A brief period of light freezing rain may create slippery travel conditions along/north of a Macomb to Danville line this morning.

Temperatures will be well above average with highs in the low 80s to low 90s today, and overnight lows in the 60s tonight. Highs on Sunday will be a couple degrees cooler ahead of the next frontal boundary, but will still range in the 80s areawide. Overall, the primary concern continues to be the low to medium potential for patchy to areas of fog and sea fog development.
BT Sunday night, an upper low and Arctic front will plunge into the Northern Rockies.
244 AM PST Sat Feb 8 2025 Drier and a little warmer this weekend with weak offshore flow.
626 AM EST Sat Feb 8 2025 (Today through Sunday) Deep layer ridging, and the sturdy body of high pressure, will prevail throughout the weekend. High temperatures will be just above normal, rising into the low to mid 80s each day with overnight lows cooling into the 60s.
