250 PM EST FRI JAN 24 2025
VALID 00Z SAT JAN 25 2025 - 00Z MON JAN 27 2025
...ELEVATED FIRE WEATHER CONDITIONS CONTINUE IN SOUTHERN
CALIFORNIA, PRECIPITATION EXPECTED TO BRING RELIEF SATURDAY INTO
SUNDAY...
...BELOW AVERAGE TEMPERATURES CONTINUE IN THE SOUTH AND EAST,
GRADUAL WARM UP ANTICIPATED THIS WEEKEND...
THE FORECAST REMAINS ON TRACK FOR A DEEP UPPER-LOW AND ASSOCIATED
FRONTAL SYSTEM TO DESCEND THROUGH THE WESTERN U.S. BEFORE CLOSING
OFF AND STALLING OVER SOUTHERN CALIFORNIA THIS WEEKEND. WITH THE
ARRIVAL OF THIS SYSTEM, WIDESPREAD LIGHT TO MODERATE RAIN AND
MOUNTAIN SNOWS ARE EXPECTED TO BEGIN LATE TONIGHT FOCUSED OVER
CENTRAL/SOUTHERN CALIFORNIA AND THE GREAT BASIN. WHILE MUCH OF THE
PRECIPITATION SHOULD BRING MUCH NEEDED RELIEF TO THE SOUTHERN
CALIFORNIA WILDFIRES, THESE AREAS WILL ALSO NEED MONITORED FOR
BURN SCAR FLASH FLOODING AND DEBRIS FLOWS AS RAIN SHOWERS WITH
LOCALLY ENHANCED RAINFALL RATES ENTER THE AREA TOMORROW MORNING.
MOREOVER, BEFORE ANY PRECIPITATION ARRIVES LATE TONIGHT, ELEVATED
FIRE WEATHER CONDITIONS WILL PERSIST ACROSS SOUTHERN CALIFORNIA
TODAY PER THE STORM PREDICTION CENTER. AS OFFSHORE LOW PRESSURE
STRENGTHENS BENEATH THE CLOSED UPPER-LOW, THE PRESSURE GRADIENT
ACROSS THE WEST WILL TIGHTEN, RESULTING IN ELEVATED WINDS ACROSS
MUCH OF THE WEST ON SATURDAY AND SUNDAY.
EAST OF THE ROCKIES, LOW PRESSURE TRACKING ACROSS THE NORTHERN
TIER WILL PUSH A COUPLE OF COLD FRONTS SOUTH ACROSS THE CENTRAL
U.S. WHILE HIGH PRESSURE BUILDS OVER THE SOUTHEAST. THE FIRST
FRONT WILL DROP SOUTH ACROSS THE NORTHERN AND CENTRAL PLAINS
TODAY, USHERING IN A COOLER AIRMASS IN ITS WAKE ACROSS THE PLAINS
STATES. BY SUNDAY, THE FRONT SHOULD APPROACH THE GULF COAST,
LEADING TO SHOWERS AND THUNDERSTORMS IN THE SOUTHERN PLAINS AND
LOWER MISSISSIPPI VALLEY AS IT INTERACTS WITH A MOIST PRE-FRONTAL
AIRMASS. TO THE NORTH, A REINFORCING COLD FRONT WILL DROP INTO THE
NORTHERN PLAINS AND UPPER MIDWEST ON SATURDAY, LIKELY LEADING TO
SNOW SHOWERS AND LOCALLY HEAVY LAKE EFFECT SNOW ACROSS THE
NORTHERN TIER AND GREAT LAKES REGIONS.
TEMPERATURES WILL REMAIN BELOW AVERAGE TODAY AND SATURDAY FOR MOST
OF THE SOUTH AND EAST. SOME OF THE MOST NOTABLE DEPARTURES FROM
AVERAGE WILL BE ALONG THE GULF COAST TO THE SOUTHEAST WHERE LOWS
ARE FORECAST TO BE IN THE 20S AND 30S AND HIGHS MAY ONLY REACH THE
40S AND LOWER 50S. DAYTIME HIGHS WILL LIKELY HELP TO MELT SNOW
COVER FROM THE RECENT HISTORIC WINTER STORM, BUT LIQUID WATER FROM
MELTED SNOW MAY REFREEZE OVERNIGHT WHEN TEMPERATURES DROP BELOW
FREEZING. TEMPERATURES WILL GRADUALLY MODERATE THROUGH THE
WEEKEND, TRENDING CLOSER TO NORMAL BY EARLY NEXT WEEK. BELOW
AVERAGE TEMPERATURES ARE ALSO EXPECTED IN THE WEST UNDERNEATH THE
UPPER LOW, AND HIGHS COULD BE 15-25 DEGREES BELOW AVERAGE IN THE
ROCKIES OVER THE WEEKEND.
