-- Changed Discussion --
(TONIGHT THROUGH SUNDAY)...HIGHER PRESSURE AT THE SURFACE AND ALOFT CONTINUES ACROSS THE EASTERN TENNESSEE VALLEY THIS AFTERNOON WITH ONLY A FEW SHOWERS DEVELOPING OVER SOUTHWEST NORTH CAROLINA AND SOUTHERN TENNESSEE VALLEY. UPPER FLOW IS STEERING THE SHOWERS SOUTH INTO GA. NOT EXPECTING MUCH MORE ACTIVITY NEXT FEW HOURS WITH SKIES BECOMING MOSTLY CLEAR THIS EVENING. CONTINUED LOW POPS NORTH CAROLINA EARLY THEN NO RAIN OVERNIGHT. OVERALL UPPER AIR PATTERN DOES NOT CHANGE SUNDAY WITH ONLY ISOLATED SHOWERS AND STORMS AGAIN. POSSIBLY A FEW MORE THAN TODAY. TEMPERATURES WILL ALSO STAY SLIGHTLY ABOVE NORMAL IN THE LOWER TO MID 90S WITH COOLER LOWS EARLY SUNDAY ACROSS THE NE IN THE MID 60S BUT NEAR 70 TO LOWER 70S CENTRAL AND SOUTHERN VALLEY. PATCHY FOG AGAIN IN EARLY NEAR THE LAKES. .LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)...MOISTURE INCREASES AS WE START THE WORK WEEK, WHICH WILL LEAD TO SOME SLIGHT CHANCES FOR SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE EARLY PART OF THE WEEK. SOME WEAK ENERGY WILL MOVE ACROSS A COUPLE OF TIMES NEXT WEEK ALLOWING FOR SOME CHANCES FOR RAIN IN THE AREA. TEMPS WILL REMAIN SLIGHTLY ABOVE AVERAGE FOR THE FIRST HALF OF THE WEEK. OVERALL PATTERN CHANGES AS WE MOVE INTO THE SECOND HALF OF THE WEEK AS A LOW PRESSURE SYSTEM MOVES ACROSS THE UNITED STATES/CANADIAN BORDER FORCING THE RIDGE BACK TO OUR WEST. THE ASSOCIATED COLD FRONT WILL MOVE INTO THE AREA ON THURSDAY AND BRINGING WITH IT SOME OF THE BEST PRECIPITATION CHANCES FOR THIS 7-DAY FORECAST. MODELS WANT TO LINGER RAIN CHANCES BEHIND THE FRONT, SO HAVE MAINTAINED SOME SLIGHT CHANCES FOR A COUPLE OF PERIODS AFTER THE FRONT MOVES THROUGH, EVEN THOUGH IT LOOKS LIKE WE DRY OUT QUICKLY BEHIND THE FRONT. TEMPERATURES ACROSS THE AREA WILL DROP DOWN TO AROUND NORMAL DUE TO THE FRONT AND ASSOCIATED INCREASE IN CLOUD COVERAGE. FRONT PUSHES AWAY THE MOISTURE AND RAIN CHANCES DIMINISH AS WE HEAD INTO NEXT WEEKEND.
