LEVEL TROF OVER THE EASTERN PART OF THE COUNTRY THANKSGIVING DAY WILL

BY SATURDAY AND SATURDAY NIGHT...THE SFC HIGH PRESSURE WILL BE MOVING

TO DEVELOP OVER THE PLAINS STATES. BY LATE SUNDAY NIGHT INTO

OVER THE SOUTHERN PLAINS...LIKELY MOVING EAST-NORTHEAST TOWARD THE
TENNESSEE VALLEY REGION THROUGH MONDAY NIGHT. THIS SHOULD BRING THE
ASSOCIATED COLD FRONT ACROSS THE FCST AREA...MOST LIKELY MONDAY
AFTERNOON AND MONDAY NIGHT. RAIN CHANCES WILL GO UP SHARPLY MONDAY IN
ASSOCIATION WITH THIS SYSTEM...AND THERE IS A GOOD CHANCE OF
THUNDERSTORMS ACROSS THE ENTIRE AREA DURING THE SUNDAY NIGHT THROUGH
MONDAY NIGHT TIME FRAME. AT THIS TIME...THE AREA IS NOT OUTLOOKED FOR
SEVERE WEATHER...BUT THIS WEATHER PATTERN HAS THE POTENTIAL TO RESULT
IN SOME STRONG TO SEVERE STORMS OVER OUR AREA AROUND THE MONDAY AND
MONDAY NIGHT TIME FRAME. WE WILL HAVE TO MONITOR FOR THIS
POSSIBILITY...AND ADJUST THE FCST ACCORDINGLY AS WE GET CLOSER TO
THE EVENT AND MORE DATA BECOMES AVAILABLE. RAIN CHANCES LOOK TO
CONTINUE THROUGH TUESDAY IN THE WAKE OF THE FRONT AS UPPER DYNAMICS
REMAIN IN PLACE ACROSS THE REGION...BUT THIS PCPN IS EXPECTED TO BE

REGION FROM THE SOUTHERN PLAINS.  A SMALL CRAFT ADVISORY MAY BE
REQUIRED FOR THE 20-60 NM PORTION FOR THURSDAY AFTERNOON AND EVENING
AS WINDS NEAR 20 KNOTS OFFSHORE.  THE OFFSHORE FLOW SUBSIDES QUICKLY
FRIDAY MORNING AS THE CENTER OF THE SURFACE HIGH NEARS THE AREA THEN
