SURFACE HIGH PRESSURE WILL FOLLOW SUIT AND ALSO DRIFT EAST INTO PA AND NY. WEAK EASTERLY LOW LEVEL FLOW ALONG THE SMOKYS COULD PRODUCE AN AFTERNOON CHANCE TO SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS IN THE HIGHEST ELEVATIONS OF E TN AND PERHAPS SW NC. THERE SHOULD ALSO BE A SLIGHT INCREASE OF CLOUD COVER BY THE AFTERNOON ACROSS THE FORECAST AREA AS WELL AS INCREASING MAXIMUM DAYTIME TEMPERATURES. .LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)...THURSDAY NIGHT LOWS NOT QUITE AS COOL AS EARLIER IN THE WEEK BUT STILL A FEW DEGREES BELOW NORMAL FOR THIS TIME OF YEAR.

PRECIP CHANCES INCREASE THIS WEEKEND AS MOISTURE RETURNS. A WEAK LOW MIGRATES NORTH OUT OF THE GULF AND INTO OUR AREA ON SATURDAY AND A WEAK UPPER TROUGH MOVES THROUGH ON SUNDAY. BOTH THESE FEATURES WILL YIELD SLIGHT CHANCE/CHANCE SHOWERS AND STORMS. WEAK LOW MIGRATES WEST ON MONDAY BUT WILL REMAIN CLOSE ENOUGH TO STILL GENERATE SLIGHT CHANCE/CHANCE POPS THROUGH THE DAY.
