AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
135 PM EDT WED MAY 22 2013

.AVIATION...
-- Changed Discussion --
CURRENT SURFACE ANALYSIS SHOWS A WEAK COLD FRONT OVER THE MS RIVER
VALLEY...WITH AN OUTFLOW BOUNDARY OVER THE FORECAST AREA FROM LAST
NIGHT`S CONVECTION OVER MIDDLE TN. A MODERATELY UNSTABLE AIR MASS IS
PROGGED TO DEVELOP THIS AFTERNOON AS AN UPPER-LEVEL TROUGH SWINGS
EASTWARD ACROSS THE TN RIVER VALLEY. AS A RESULT...SCATTERED
CONVECTION WILL CONTINUE TO DEVELOP THIS AFTERNOON...BUT TIMING THE
EXACT OCCURRENCE AT THE TAF SITES WILL REMAIN PROBLEMATIC. THUS...
WILL JUST MENTION VCTS AT THE TAF SITES UNTIL EARLY EVENING. FOG
SHOULD DEVELOP AGAIN LATE TONIGHT...ESPECIALLY IN AREAS THAT RECEIVE
RAIN THIS AFTERNOON AND EVENING...BUT WILL ONLY MENTION MVFR
VISIBILITIES AT KTRI SINCE CLOUDS MAY LIMIT THE EXTENT OF THIS FOG.
WINDS SHOULD INCREASE AFTER SUNRISE ON THURSDAY...AS A COLD FRONT
APPROACHES THE TAF SITES.
