CLOUDS AND COOL WESTERLY SURFACE FLOW HELD TEMPERATURES IN THE MIDDLE AND UPPER 60S OVER MOST AREAS DURING THE EARLY AFTERNOON, WITH SOME READINGS AS CHILLY AS THE MIDDLE AND UPPER 50S OVER SOME OF OUR EXTREME NRN TN COUNTIES AND SW VA COUNTIES. EXPECT CLOUDS TO GRADUALLY CLEAR TONIGHT, WITH LOWS DIPPING DOWN INTO THE MIDDLE AND UPPER 40S BY SUNRISE FRIDAY. WE GET A DRY START TO OUR MEMORIAL DAY WEEKEND, AS HIGH PRESURE BUILDS EASTWARD FROM THE OHIO RIVER VALLEY TO OFF THE MID-ATLANTIC COAST BY LATE SATURDAY. AT LEAST A SMALL CHANCE FOR SHOWERS AND THUNDERSTORMS RETURNS TO OUR FA ON MONDAY AS SOUTHERLY SURFACE FLOW REDEVELOPS. TEMPERATURES WILL BE WARMING EACH DAY THROUGH NEXT MONDAY, WITH HIGHS ON FRIDAY MAINLY IN THE 70S, IN THE MID 70S TO AROUND 80 ON SATURDAY, AND REACHING THE MIDDLE AND UPPER 80S BY SUNDAY AND MONDAY. .LONG TERM...UPPER RIDGE PULLS SLOWLY EASTWARD TUESDAY THROUGH THURSDAY, AS WE COME UNDER THE INFLUENCE OF A 50H TROUGH OVER THE EASTERN ROCKIES AND MISSISSIPPI VALLEY. AS A RESULT, CLOUDS AND THE CHANCE FOR SHOWERS WILL BE ON THE INCREASE TOWARD THE MIDDLE AND LATTER PART OF NEXT WEEK, ESPECIALLY TOWARD THE END OF THE PERIOD WHEN MODELS POINT TO A SHORTWAVE, PERHAPS, RIDING INTO THE OHIO RIVER VALLEY. TEMPERATURES WILL REMAIN QUITE MILD, WITH HIGHS MAINLY IN THE 80S AND LOWS IN THE 60S.
