DISCUSSION
WINDS WILL BE ON THE INCREASE FROM SUNDAY THROUGH TUESDAY AS A
FRONTAL BOUNDARY DEVELOPS AND MOVES TOWARDS THE SOUTHEAST US. IN
RESPONSE, EXPECT AN INCREASE IN MOISTURE ON THESE ELEVATED
SOUTHERLY WINDS. AS MOISTURE INCREASES, A FEW RAIN SHOWERS OR
ISOLATED THUNDERSTORMS MAY DEVELOP DURING THE AFTERNOON HOURS,
BUT A WIDESPREAD COVERING NOR HEAVY DOWNPOUR IS ANTICIPATED. RAIN
CHANCES INCREASE SHARPLY LATE TUESDAY OR EARLY WEDNESDAY AND
REMAIN VERY ELEVATED THROUGH THE END OF THE WEEK.
