.AVIATION...
LIGHT RAIN WILL BEGIN TO SPREAD NORTHWARD INTO CHA OVER THE NEXT
FEW HOURS...FOLLOWED BY TYS AROUND NOON. EXPECT THAT CIGS WILL
REMAIN VFR FOR SEVERAL HOURS AFTER ONSET. A SOUTHEAST FLOW ABOVE
THE SURFACE WILL CREATE A DOWSLOPE FLOW THAT SHOULD DELAY PRECIP
AND LOWER CIGS AT TRI UNTIL THE LATE AFTERNOON. ONCE THE STRONGER
LIFT ASSOCIATED WITH A SURFACE FRONT MOVES IN LATE THIS AFTERNOON
AND THIS EVENING...CIGS AND VIS SHOULD LOWER TO MVFR. THUNDER
CANNOT BE RULED OUT AT CHA OR TYS...BUT IT SHOULD BE ISOLATED AND
WILL NOT MENTION IT IN THE TAFS YET. WINDS MAY ALSO BE GUSTY AROUND
THE TIME OF FRONTAL PASSAGE. WINDS WILL SHIFT TO W-SW BEHIND THE
FRONT OVERNIGHT. ALTHOUGH PRECIP WILL END WITH THE FROPA...EXPECT
MVFR CIGS TO REMAIN IN PLACE AS LOW LEVEL MOISTURE LINGERS BEHIND
IT.
