AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
158 AM EDT WED MAY 22 2013

.AVIATION...-- Changed Discussion --
LOOKS LIKE AVIATION WILL BE IMPACTED BY CONVECTION
TODAY IN THE GREAT VALLEY AS MODELS INDICATE TWO OR THREE SHORTER
WAVELENGTH FEATURES WILL BUILD ACROSS THE SOUTHERN APPALACHIAN
REGION IN VERY SLOW WEATHER PATTERN GOVERNED BY MID AMERICAN UPPER
LEVEL TROUGH. SOME ISOLATED CONVECTION ALIGNED ON THE WESTERN
PLATEAU DOESN`T APPEAR TO IMPACT THE TERMINALS THROUGH THE FIRST
SEVERAL HOURS OF THE FORECAST. AVIATION WILL MOST LIKELY BE
AFFECTED AROUND MID DAY THROUGH THE AFTERNOON AS LIFT WITH INITIAL
WAVE DRIVING CONVECTION ACROSS WEST TENNESSEE AND NORTHERN
MISSISSIPPI HEADS EAST. DECENT AMOUNT OF JUICE AVAILABLE IN
UNSTABLE ENVIRONMENT FOR STORMS SO JUST WENT AHEAD AND USED A
PREVAILING CONVECTIVE GROUP FOR THE MAIN EVENT AT THE TERMINALS.
APPLIED SOME POST EVENT VICINITY SHOWERS FOR THE LATER EVENING
PERIOD. LOOKS LIKE BEST BET FOR SOME MVFR/IFR FOG WILL BE AT TRI
WHERE DEBRIS CLOUDS FROM TUESDAY NIGHT STORMS MOVES AWAY TO THE
EAST ALLOWING FOR SOME RADIATION.-- End Changed Discussion --
