...HEAVY SNOW FOR NORTHERN PARTS OF THE MID-ATLANTIC...

...RAIN/FREEZING RAIN FOR SOUTHERN MID-ATLANTIC...

...TEMPERATURES BE 10 TO 30 DEGREES BELOW AVERAGE FROM THE
SOUTHERN PLAINS TO NORTHEAST...

AN ARCTIC AIR CONTINUES TO SURGE SOUTHWARD BEHIND A COLD FRONT
SWEEPING ACROSS THE SOUTHEAST U.S. WITH AMPLE MOISTURE STREAMING
NORTHWARD FROM THE GULF OF MEXICO HEAVY SNOW IS EXPECTED ACROSS
THE NORTHERN MID ATLANTIC WHERE SUB FREEZING TEMPERATURES HAVE
SETTLED IN AT ALL LEVELS. SHALLOW COLD AIR FILTERING INTO THE
SOUTHERN MID ATLANTIC WILL CHANGE RAIN TO SLEET AND FREEZING RAIN
THIS AFTERNOON AND COULD END AS A BRIEF PERIOD OF SNOW THIS
EVENING. FURTHER SOUTH, A BAND OF CONVECTIVE PRECIPITATION IN A
SPRING-LIKE AIRMASS AHEAD OF THE COLD FRONT WILL BRING A BRIEF
PERIOD OF HEAVY RAIN FROM SOUTH CAROLINA TO FLORIDA. IN THE LOWER
MISSISSIPPI VALLEY AND SOUTHERN APPALACHIANS THE PRECIPITATION
COULD END AS LIGHT FREEZING RAIN AND SLEET.

AS THE COLD FRONT EXITS THE EAST COAST THE SOUTHERN PORTION WILL
BE SLOW TO PUSH THROUGH FLORIDA. LIGHT SHOWERS WILL BE POSSIBLE
THROUGH THE PERIOD ESPECIALLY ALONG THE ATLANTIC COAST OF FLORIDA.
COLD AIR WILL SETTLE IN ACROSS MUCH OF THE EASTERN U.S. WITH HIGH
TEMPERATURES UP TO 30 DEGREES BELOW NORMAL POSSIBLE IN SOME
PLACES.

WITH HIGH PRESSURE LOCKED IN ACROSS THE WESTERN AND SOUTHERN U.S.
A SERIES OF SHORTWAVE TROUGHS WILL SLIDE ACROSS SOUTHERN CANADA
AND THE GREAT LAKES OVER THE NEXT FEW DAYS. WARM ADVECTION INTO
THE CENTRAL AND NORTHERN PLAINS WILL LEAD TO ABOVE NORMAL
TEMPERATURES THROUGH THE PERIOD. SOME LIGHT SNOW SHOWERS ARE
POSSIBLE ACROSS THE NORTHERN PLAINS AND NORTHERN GREAT LAKES LATE
FRIDAY INTO SATURDAY.
