...WINTER STORM TO TRACK FROM THE CENTRAL PLAINS TO
MID-MISSISSIPPI VALLEY TODAY THROUGH TONIGHT BEFORE IMPACTING THE
SOUTHERN MID-ATLANTIC ON WEDNESDAY WITH ACCUMULATING SNOW AND
AREAS OF SLEET/FREEZING RAIN...
...RECORD COLD TEMPERATURES AND DANGEROUSLY COLD WIND CHILLS TO
SPILL FURTHER SOUTHWARD INTO THE PLAINS WITH BELOW AVERAGE
TEMPERATURES SPANNING ACROSS MUCH OF THE EAST...
...NEXT ROUND OF MOUNTAIN SNOW AND LOWER ELEVATION RAIN EXPECTED
TO AFFECT THE PACIFIC NORTHWEST AND NORTHERN ROCKIES WEDNESDAY
INTO THURSDAY...
A LARGE POOL OF ARCTIC AIR CONTINUES TO ADVANCE FARTHER SOUTH INTO
THE MID-SECTION OF THE COUNTRY, ESPECIALLY THROUGH THE LONESTAR
STATE. TEMPERATURES ARE EXTREMELY COLD BEHIND THE FRONT AND AHEAD
OF A 1050 MB HIGH PRESSURE DOMINATING THE CENTRAL PART OF THE
COUNTRY. TEMPERATURES AS OF THIS AFTERNOON ARE BELOW ZERO AS FAR
SOUTH AS OKLAHOMA AND THE 20S IN NORTHERN TEXAS. IN ADDITION TO
THE COLD, SNOWFALL IS ONGOING ACROSS THE PLAINS AND WILL SPREAD
EASTWARD THROUGH THE DAY FOR THE TENNESSEE AND OHIO VALLEYS. THERE
IS A HIGH CHANCE OF SEEING 4 TO 8 INCHES, WITH SOME LOCALLY HIGHER
AMOUNTS. A SWATH OF SLEET/FREEZING RAIN CAN ALSO BE EXPECTED
ACROSS THE SOUTHERN PORTION OF THESE STATES FROM THIS AFTERNOON
INTO TONIGHT. THIS WILL RESULT IN DIFFICULT TRAVEL CONIDTIONS,
WITH MODERATE TO MAJOR IMPACTS FROM A COMBINATION OF SNOW AND ICE.
MEANWHILE, ACCUMULATING SNOWFALL WILL CONTINUE TO SPREAD EASTWARD
ACROSS THE SOUTHERN APPALACHIANS AND MID-ATLANTIC ON WEDNESDAY.
AREAS FROM NORTHERN NORTH CAROLINA TO THE DELMARVA CAN EXPECT
SNOWFALL POTENTIAL TO EXCEED 6 INCHES WITH LOCALLY HIGHER AMOUNTS
POSSIBLE. ON THE SOUTHERN END OF THE SNOWFALL IN NORTH CAROLINA,
THERE IS A HIGHER CHANCE FOR LOCALLY SIGNIFICANT ICE ACCUMULATIONS
THAT COULD RESULT IN DANGEROUS TRAVEL CONDITIONS. MEANWHILE,
LAKE-EFFECT SNOW WILL ONCE AGAIN IMPACT THE SNOW BELT REGION
DOWNWIND FROM THE GREAT LAKES.
WITH THE FRIGID AIRMASS SETTLING INTO MOST OF THE CENTRAL AND
EASTERN U.S., RECORD COLD TEMPERATURES ARE LIKELY TO BE SET. THE
SOUTHERN U.S. WILL HAVE HIGH TEMPERATURES IN THE 30S AND 40S, AND
THE PLAINS WILL HAVE HIGH TEMPERATURES IN THE LOW SINGLE DIGITS TO
THE TEENS. LOW TEMPERATURES ACROSS THE NORTHERN PLAINS WILL BE
FRIGIDLY COLD IN THE -20S AND -30S, AND THE SOUTHERN PLAINS AND
OHIO AND TENNESSEE VALLEYS WILL SEE LOW TEMPERATURES IN THE SINGLE
DIGITS AND APPROACH ZERO. THE GULF COAST MAY APPROACH LOW
TEMPERATURE VALUES IN THE 20S. GUSTY WINDS WILL MAKE IT FEEL AS
COLD AS -30 TO EVEN -60 ACROSS THE NORTHERN PLAINS. THE SOUTHERN
PLAINS COULD SEE WINDCHILL TEMPERATURES AS LOW AS THE -20S.
EXTREME COLD WARNINGS AND COLD WEATHER ADVISORIES ARE CURRENTLY
SPAN ACROSS THE NORTHERN PLAINS AND UPPER MIDWEST DOWN TO CENTRAL
TEXAS TO ADDRESS THESE FRIGID TEMPERATURES. BE SURE TO DRESS IN
LAYERS INCLUDING A HAT, FACE MASK, AND GLOVES IF YOU MUST GO
OUTSIDE!
ELSEWHERE, MOUNTAIN SNOW AND LIGHT LOWER ELEVATION SNOW CONTINUES
ACROSS THE NORTHERN ROCKIES THROUGH THE REMAINDER OF TODAY. THEN,
BY LATE WEDNESDAY AND EARLY THURSDAY, THE NEXT PACIFIC STORM
SYSTEM ENTERS THE NORTHWEST. HIGH ELEVATION SNOW AND HIGH WINDS
ARE POSSIBLE WITH THIS AREA OF LOW PRESSURE. THE WESTERN TO
CENTRAL GULF COAST MAY ALSO SEE 2-3 INCHES OF RAINFALL AS A COLD
FRONT SWEEPS THROUGH THE AREA. SOME ISOLATED FLASH FLOODING AND
STRONG, GUSTY WINDS MAY OCCUR TODAY AS THE WEATHER PREDICTION
CENTER HAS A MARGINAL RISK FOR EXCESSIVE RAINFALL, AND THE STORM
PREDICTION CENTER HAS A MARGINAL RISK FOR SEVERE THUNDERSTORMS.
