AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
257 PM EDT SUN AUG 30 2015

.SHORT TERM...(TONIGHT AND TOMORROW)...UPPER LOW CONTINUES LIFTING
NORTH NORTHEAST OVERNIGHT AS IT GETS SWEPT UP BY WEAK INCOMING UPPER
TROUGH. BOTH OF THESE FEATURES ARE RATHER WEAK AS THEY MERGE
TOGETHER AND SHOULDN`T POSE A THREAT FOR ANY WIDESPREAD RAINS. WILL
HAVE CHANCE AND SLIGHT CHANCE SHOWERS IN OVERNIGHT. FOG IS TOUGH TO
FIGURE OUT TONIGHT DUE TO UNCERTAINTY OF PRECIP COVERAGE AND HOW
MUCH CLEARING...IF ANY...CAN TAKE PLACE TOWARD EARLY MORNING. NOT
ENOUGH CONFIDENCE TO PUT PATCHY FOG WORDING IN ZONES BUT A FEW
ISOLATED AREAS OF FOG CAN`T BE RULED OUT FOR LOCATIONS THAT SEE
RAIN. LOWS WILL BE NEAR NORMAL TONIGHT.

FOR TOMORROW...PWS REMAIN SOMEWHAT ELEVATED BUT THERE JUST ISN`T ANY
STRONG FORCING PRESENT TO GENERATE MUCH IN THE WAY OF CONVECTION OR
PRECIP FOR THAT MATTER. WILL HAVE CHANCE AND SLIGHT CHANCE POPS IN
FOR TOMORROW WITH SLIGHT CHANCE OF A THUNDERSTORM DURING THE
AFTERNOON HOURS. MAX TEMPS TOMORROW EXPECTED TO BE A FEW DEGREES
BELOW NORMAL.


.LONG TERM...(TOMORROW NIGHT THROUGH SUNDAY)...FIRST HALF OF NEXT
WEEK LOOKS TO REMAIN MOSTLY DRY FOR MUCH OF THE AREA AS THE UPPER
TROUGH MOVES OFF TO OUR EAST AND TAKES AWAY MOST OF THE MOISTURE
WITH IT. WE LOOK TO REMAIN RELATIVELY DRY AFTER THAT, WITH THE NEXT
ROUND OF MOISTURE POSSIBLY MOVING IN WITH WHAT LITTLE REMAINS OF
ERIKA. ISOLATED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE, BUT
COVERAGE IS NOT EXPECTED TO BE VERY WIDE. BETTER CHANCES WILL
LIKELY HAVE TO WAIT TILL CLOSER TO THE WEEKEND WHEN MOISTURE
RETURNS WITH SOUTHERLY FLOW AHEAD OF ANOTHER TROUGH MOVING IN FROM
THE WEST. DUE TO DECREASE IN RAIN CHANCES AND CLOUD COVERAGE, HAVE
GONE AHEAD WITH THE ABOVE AVERAGE TEMPERATURES WITH SOME PLACES
REACHING NEAR 90 DEGREES NEXT WEEK.
