MID-ATLANTIC THROUGH THIS EVENING ...
...RECORD COLD TEMPERATURES WILL SETTLE SOUTH TOWARD THE GULF
COAST THROUGH THE NEXT COUPLE OF DAYS WHILE DANGEROUSLY COLD WIND
CHILLS OVER THE NORTHERN PLAINS INTO FRIDAY...

MODERATE SNOWFALL IS ONGOING THIS AFTERNOON ACROSS NORTH CAROLINA
AND THE SOUTHERN MID-ATLANTIC AND IS EXPECTED TO FALL THOUGH
THURSDAY MORNING FOR THESE REGIONS, WITH ACCUMULATIONS OF 6-10
INCHES OF SNOW POSSIBLE. ADDITIONALLY, AREAS OF SLEET/FREEZING
RAIN ARE ALSO EXPECTED JUST TO THE SOUTH OF THE SWATH OF SNOWFALL
ACROSS THE COASTAL PLAINS OF NORTH CAROLINA THIS AFTERNOON INTO
EARLY THIS EVENING. TRAVEL WILL BE DIFFICULT IN ICY AREAS AND IN
AREAS OF LOW VISIBILITY. OTHER WINTER WEATHER CONCERNS ACROSS THE
EAST INCLUDE A CHANCE FOR LIGHT SNOW SHOWERS THURSDAY ACROSS THE
MID-ATLANTIC AND APPALACHIANS AS AN UPPER LOW MOVES ACROSS THE
AREA. LIGHT SNOWFALL ACCUMULATIONS HAVE A LOW PROBABILITY ACROSS
THESE REGIONS. LAKE EFFECT SNOWFALL MAY ALSO BE ONGOING,
ESPECIALLY DOWNWIND OF LAKE MICHIGAN FOR TOMORROW.
A COLD FRONT WILL SWEEP THROUGH FLORIDA THIS AFTERNOON AND BRING
THE CHANCE OF SHOWERS AND THUNDERSTORMS. MORE IMPORTANTLY, FLORIDA
WILL JOIN THE MILLIONS OF PEOPLE EXPERIENCING THIS ARCTIC AIR
OUTBREAK. HIGH TEMPERATURES WILL DROP FROM THE 70S AND 80S TO THE
50S AND 60S AND LOW TEMPERATURES IN THE 30S AS FAR SOUTH AS
ORLANDO BY LATER THIS WEEK. THE REST OF THE COUNTRY SHOULD BE IN
THE PEAK OF THE ARCTIC AIR OUTBREAK. HIGH TEMPERATURES WILL SLOWLY
MODIFY BY THE END OF THE WEEK, BUT WILL REMAIN BELOW AVERAGE WITH
TEMPERATURES IN THE TEENS, TWENTIES, AND THIRTIES ACROSS THE
PLAINS, MIDWEST, AND EASTERN U.S.. WIND CHILLS WILL BE HAZARDOUSLY
COLD. TEMPERATURES WILL FEEL BELOW ZERO IN THE SOUTHERN PLAINS,
AND THE NORTHERN PLAINS MAY FEEL AS COLD AS -20 TO -30 IN THE
NORTHERN PLAINS FOR AT LEAST THE NEXT DAY OR TWO WITH THE
INFLUENCE OF THE ARCTIC HIGH PRESSURE. BE SURE TO DRESS IN LAYERS
INCLUDING A HAT, FACE MASK, AND GLOVES IF YOU MUST GO OUTSIDE!
ANOTHER ROUND OF UNSETTLED WEATHER OF RAIN AND WIND IS APPROACHING
THE PACIFIC NORTHWEST AS AN AREA OF LOW PRESSURE AND ATTENDANT
COLD FRONT SWEEP SOUTHEASTWARD. A PERIOD OF MODERATE TO LOCALLY
HEAVY RAIN NEAR THE COAST IS ONGOING TODAY, AND SOME HEAVY SNOW IS
EXPECTED ACROSS THE CASCADES AND NORTHERN ROCKIES THURSDAY. THE
COLD FRONT IS PROGGED TO PASS SOUTHWARD ACROSS THE WEST TOWARD THE
FOUR CORNERS REGION, BUT THE FRONT WILL BE RELATIVELY WEAK AND
TEMPERATURES SHOULD REMAIN AROUND 5-10 DEGREES ABOVE AVERAGE, AS
WELL AS MOSTLY DRY, FOR THE SOUTHWEST.
