.DISCUSSION...
LOW PRESSURE ALONG THE SOUTHEAST COAST WILL DRIFT SLOWLY EAST AND 
OFFSHORE OVERNIGHT INTO SUNDAY. THIS SHOULD ALLOW ANY RESIDUAL

TO TAPER OFF LATER TONIGHT. 

HIGH PRESSURE WILL STRENGTHEN ALONG THE MID ATLANTIC COAST ON SUNDAY 
PROVIDING A DRIER EASTERLY FLOW INTO SUNDAY NIGHT. WINDS WILL 
GRADUALLY TURN MORE SOUTHWEST MONDAY AND INCREASE ON TUESDAY AS THE 
HIGH SLIDES EAST AND THE NEXT COLD FRONT APPROACHES FROM THE WEST. 

MOISTURE ASSOCIATED WITH THIS FRONT WILL BRING THE NEXT CHANCE OF 
WETTING RAINFALL IN THE FORM OF SHOWERS AND STORMS TUESDAY AFTERNOON. 
HIGH PRESSURE ALONG WITH GUSTY NORTHWEST WINDS AND MUCH DRIER AIR 
FOLLOWS THE FRONT ON THURSDAY.
