AS ADVERTISED...RAIN HAS OVERSPREAD THE ENTIRE CWA WITH THE PIPELINE EXTENDING SOUTH INTO THE CAROLINAS. SURFACE LOW PRESSURE OVER NORTHERN FLORIDA HAS A TROUGH EXTENDING NORTH INTO THE EASTERN GREAT LAKES. AN UPPER LOW ORGANIZING OVER EASTERNN IOWA WILL PROVIDE THE INFLUX OF MOISTURE AT THE UPPER LEVELS. THIS...ALONG WITH A SERIES OF SHORTWAVES...WILL BRING STEADY LIGHT TO MODERATE RAIN OVERNIGHT. THUNDERSTORMS HAVE BEEN CONFINED TO THE FAR EASTERN EDGE OF THE STEADY RAIN WHERE DEWPOINTS HAVE ROCKETED INTO THE 70S. SPOTTER REPORTS FROM AREAS RECEIVING HEAVY RAIN INDICATE THAT 1 TO 3 INCH AMOUNTS WILL BE COMMON OVERNIGHT IN THE TROPICAL AIRMASS. TEMPERATURES WILL HOLD IN THE MID TO UPPER 60S PARALLEL WITH THE DEWPOINTS TONIGHT. AS A RESULT...THE FLASH FLOOD WATCH HAS BEEN EXTENDED TO 6 AM FOR ALL COUNTIES EXCEPT THE FAR NORTHWEST.
