CLOUD COVER TODAY HAS BEEN PERSISTING LONGER THAN THE MODELS

TRAVEL PROBLEMS AS TEMPERATURES HAVE BEEN SLOW TO RISE. THE
SITUATION WON'T IMPROVE THROUGH FRIDAY MORNING AS TEMPERATURES
WILL DROP INTO THE UPPER TEENS AND 20S TONIGHT, AND REMAIN BELOW
FREEZING UNTIL MID TO LATE MORNING ON FRIDAY. CLOUD COVER WILL BE
INCREASING AS WELL FRIDAY MORNING, SO THERE WON'T BE MUCH SUNSHINE
TO HELP THE SITUATION.
A SHORTWAVE TROUGH IN THE NW FLOW ALOFT WILL CROSS THE AREA FRIDAY
AFTERNOON THROUGH FRIDAY NIGHT. FALLING TEMPERATURES ALOFT WILL
GENERATE SCATTERED TO NUMEROUS SHOWERS IN SW VA AND NE TN,
