TROUGHING OVER THE CENTRAL U.S. WILL SUPPORT THE DEVELOPMENT OF A
MID-LATITUDE CYCLONE OVER THE NORTHEAST TODAY. THE ATTENDANT COLD
FRONT EXTENDS FROM THE INTERIOR NORTHEAST BACK DOWN TO THE
SOUTHERN HIGH PLAINS. SCATTERED TO ISOLATED SHOWERS AND
THUNDERSTORMS ARE LIKELY TO DEVELOP AROUND AND BEHIND THIS COLD
FRONT TODAY, ESPECIALLY OVER THE SOUTHERN PLAINS AND LOWER
MISSISSIPPI VALLEY. RAIN AND SNOW SHOWERS WILL CONTINUE FROM THE
NORTHERN PLAINS THROUGH THE GREAT LAKES AND INTO THE NORTHEAST
TODAY. POCKETS OF FREEZING RAIN MAY OCCUR OVER PARTS OF THE
NORTHERN APPALACHIANS THIS MORNING. THE RAIN AND THUNDERSTORMS
SHIFT SOUTH INTO THE TEXAS/CENTRAL GULF COAST ON FRIDAY AND
SATURDAY AS THE COLD FRONT WORKS ITS WAY THROUGH THE SOUTHEAST.
AN AXIS OF ABOVE NORMAL TEMPERATURES EXTENDING FROM THE SOUTHERN
PLAINS TO THE MID-ATLANTIC WILL SOON BE WASHED AWAY BY THE
APPROACHING COLD FRONT THIS AFTERNOON AND EVENING. IN THE
MEANTIME, HIGH TEMPERATURES IN THE 70S AND 80S WILL BE 15-25
DEGREES ABOVE NORMAL. MANY PARTS OF THE THE SOUTHEAST,
SOUTHERN/CENTRAL APPALACHIANS AND MID-ATLANTIC WILL EXPERIENCE
NEAR OR RECORD BREAKING HIGH TEMPERATURES TODAY. TEMPERATURES WILL
FALL DRASTICALLY ON THE BACKSIDE OF THE COLD FRONT OVER THE
SOUTHERN HIGH PLAINS TODAY, WITH HIGHS IN THE 40S TO LOW 50S
REPRESENTING A 15-25 DEGREE DEPARTURE FROM NORMAL. THIS IS
EXPECTED TO CONTINUE INTO FRIDAY AS WELL WHILE HIGH PRESSURE
BUILDS OVER THE CENTRAL CONUS. TEMPERATURES FALL WELL BELOW
AVERAGE ACROSS THE EAST COAST THIS VETERANS DAY WEEKEND.
A SERIES OF LOW PRESSURE SYSTEMS WILL BRING LOW ELEVATION RAIN AND
MOUNTAIN SNOW TO THE NORTHWEST BEGINNING THIS AFTERNOON. ANYWHERE
BETWEEN 1-2 FEET OF SNOW ARE EXPECTED FOR THE NORTHERN CASCADES,
WHILE MUCH LIGHTER AMOUNTS ARE LIKELY ACROSS THE NORTHERN ROCKIES
OVER THE NEXT 2 DAYS. ELSEWHERE, A CRITICAL FIRE WEATHER AREA WAS
INTRODUCED OVER PARTS OF SOUTHERN CALIFORNIA INCLUDING VENTURA AND
LOS ANGELES COUNTIES. THE GREATEST RISK OF FIRES WILL BE LATE THIS
MORNING INTO EARLY THIS AFTERNOON WHEN WIND GUSTS OF OVER 50MPH
AND THE DRIEST CONDITIONS WILL OCCUR.
