235 AM EST MON DEC 01 2025
VALID 12Z MON DEC 01 2025 - 12Z WED DEC 03 2025
...MONDAY WILL BRING A MESSY WINTRY MIX ACROSS THE
OZARKS/MID-SOUTH INTO THE OHIO VALLEY WITH LIGHT TO MODERATE
SNOWFALL FOR PORTIONS OF THE MIDWEST/LOWER GREAT LAKES...
...FIRST WINTER STORM OF THE SEASON EXPECTED FOR NEW ENGLAND AND
THE INLAND MID-ATLANTIC LATE MONDAY INTO TUESDAY WITH HEAVY SNOW
AND IMPACTFUL ICING...
...CHILLY TEMPERATURES CONTINUE ACROSS MUCH OF THE EASTERN AND
CENTRAL U.S. IN A WINTER-LIKE PATTERN...
A FEW LINGERING SNOW SHOWERS WILL CONTINUE INTO MONDAY MORNING
ACROSS PORTIONS OF THE GREAT LAKES AND INTERIOR NORTHEAST AS AN
UPPER-WAVE/SURFACE FRONTAL SYSTEM RESPONSIBLE FOR THIS PAST
WEEKEND'S WINTER STORM LIFTS INTO SOUTHEASTERN CANADA. MEANWHILE,
TO THE WEST, THE NEXT IMPACTFUL STORM SYSTEM WILL BEGIN TO TAKE
SHAPE AS AN UPPER-WAVE OVER THE ROCKIES EMERGES OVER THE PLAINS,
ENCOURAGING MOIST RETURN FLOW ALONG AND OVERRIDING A
QUASI-STATIONARY FRONTAL BOUNDARY IN PLACE ALONG THE GULF COAST. A
BROAD, EXPANDING AREA OF PRECIPITATION WILL SHIFT EASTWARD FROM
THE PLAINS/MISSISSIPPI VALLEY THIS MORNING INTO THE MIDWEST AND
SOUTHEAST THIS AFTERNOON AND EVENING. SCATTERED TO WIDESPREAD
SHOWERS AND THUNDERSTORMS ARE EXPECTED CLOSER TO THE BOUNDARY
ALONG THE GULF COAST AND INLAND OVER PORTIONS OF THE SOUTHEAST.
SOME MODERATE TO LOCALLY HEAVY RAINFALL WILL BE POSSIBLE, WITH AN
ISOLATED RISK FOR FLASH FLOODING. WITH COLDER AIR IN PLACE FURTHER
NORTH, THE PRECIPITATION WILL FIRST TRANSITION INTO A MESSY WINTRY
MIX FROM THE OZARKS/MID-SOUTH EAST THROUGH THE OHIO VALLEY, WITH
SNOW AND ICE LEADING TO HAZARDOUS TRAVEL CONDITIONS. A BROADENING
SWATH OF ACCUMULATING SNOW IS FORECAST JUST TO THE NORTH,
STRETCHING FROM THE CENTRAL PLAINS EAST THROUGH THE MIDDLE
MISSISSIPPI VALLEY AND INTO THE UPPER OHIO VALLEY/LOWER GREAT
LAKES. SOME LIGHT TO MODERATE ACCUMULATIONS CAN BE EXPECTED, WITH
LOCALLY HIGHER TOTALS WHERE SNOWFALL WILL BE ENHANCED DOWNWIND OF
THE GREAT LAKES.
AS THE UPPER-WAVE CONTINUES EASTWARD, IT WILL HELP TO
DEEPEN/ORGANIZE AN AREA OF LOW PRESSURE ALONG THE GULF COAST
FRONTAL BOUNDARY THROUGH THE DAY MONDAY, EXPECTED TO LIFT
NORTHEASTWARD AND STRENGTHEN ALONG THE EAST COAST LATE MONDAY AND
THROUGH THE DAY TUESDAY. MOIST ONSHORE FLOW IN THE COLDER AIR
NORTH OF THE SYSTEM WILL HELP TO ENHANCE WINTER PRECIPITATION
ACROSS MUCH OF NEW ENGLAND AND THE MID-ATLANTIC, ESPECIALLY INLAND
FROM THE COAST, BRINGING THE FIRST IMPACTFUL WINTER STORM OF THE
SEASON. ALTHOUGH UNCERTAINTY REMAINS WITH RESPECT TO SPECIFIC
TOTALS, THE THREAT FOR SIGNIFICANT SNOW ACCUMULATIONS ACROSS THE
INTERIOR IS RISING, WITH MORE THAN 6" POSSIBLE NORTH AND WEST OF
THE I-95 CORRIDOR. IN ADDITION, TREACHEROUS ICING IS EXPECTED
FURTHER SOUTH ALONG PORTIONS OF THE CENTRAL/SOUTHERN APPALACHIANS.
YET ANOTHER SYSTEM UPSTREAM WILL DROP INTO THE PACIFIC
NORTHWEST/NORTHERN ROCKIES BY LATER MONDAY BRINGING LOWER
ELEVATION/COASTAL RAIN AND INLAND/HIGHER ELEVATION SNOW. SNOW
SHOWERS WILL SPREAD SOUTHWARD OVER THE GREAT BASIN/CENTRAL ROCKIES
BY TUESDAY MORNING. SOME MODERATE SNOW ACCUMULATIONS ARE EXPECTED
BUT SHOULD BE LIMITED TO THE REGIONAL MOUNTAIN RANGES. JUST TO THE
NORTHEAST, AN ADDITIONAL QUICK MOVING CLIPPER-LIKE SYSTEM WILL
BRING SOME LIGHT SNOW SHOWERS TO THE NORTHERN PLAINS TUESDAY, AND
SOME MORE MODERATE SNOWFALL ACROSS THE UPPER GREAT LAKES TUESDAY
NIGHT.
TEMPERATURES REMAIN WELL-BELOW AVERAGE AND VERY CHILLY ACROSS MUCH
OF THE EASTERN AND CENTRAL U.S. AS THIS WINTER-LIKE PATTERN
CONTINUES, FEATURING BROAD, STAGNANT UPPER-TOUGHING AND REPEATED
COLD FRONTAL PASSAGES. FORECAST HIGHS THE NEXT COUPLE OF DAYS
GENERALLY RANGE FROM THE TEENS AND 20S ACROSS THE NORTHERN
PLAINS/MIDWEST; THE 30S AND 40S FOR THE CENTRAL PLAINS, OHIO
VALLEY, AND NORTHEAST/MID-ATLANTIC; AND THE 40S AND 50S FROM TEXAS
INTO THE SOUTHEAST. AREAS ALONG THE GULF COAST MONDAY AND INTO THE
SOUTHEAST ATLANTIC TUESDAY SOUTH OF THE FRONTAL BOUNDARY WILL SEE
MUCH WARMER HIGHS INTO THE 60S. DOWNSLOPING WINDS OFF THE ROCKIES
WILL ALSO BRING A WARM UP TO THE HIGH PLAINS ON TUESDAY AS
TEMPERATURES RISE INTO THE 30S/40S NORTH AND 50S/60S SOUTH.
CONDITIONS REMAIN CLOSER TO AVERAGE ACROSS THE WEST, WITH HIGHS IN
THE 40S FOR THE INTERIOR, 50S AND 60S ALONG THE WEST COAST, AND
60S AND 70S IN THE DESERT SOUTHWEST.
