AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 230 PM EDT TUE JUN 22 2010 .SHORT TERM (TONIGHT AND WEDNESDAY)...PRETTY MUCH A PERSISTENCE FORECAST THROUGH THE SHORT TERM AS UPPER RIDGING REMAINS ANCHORED OVER THE SOUTHERN THIRD OF THE CONUS. CONVECTION SHOULD ONCE AGAIN BE SUPPRESSED TOMORROW BY SUBSIDENCE INVERSION INDUCED BY UPPER RIDGING AND KEPT ISOLATED CONVECTION CONFINED TO HIGHER TERRAIN ALONG WITH NORTHEASTERN ZONES WHICH WILL BE RELATIVELY CLOSER TO MCS TRACK OVER THE OHIO VALLEY. FOR TEMPS...WHICH WILL REMAIN WELL ABOVE CLIMO...GENERALLY DID NOT DEVIATE MUCH FROM MAV GUIDANCE. APPEARS HEAT INDEX VALUES WILL APPROACH...BUT NOT QUITE MEET...HEAT ADVISORY CRITERIA. .LONG TERM (WEDNESDAY NIGHT THROUGH TUESDAY)...MODELS ARE IN GENERAL AGREEMENT THAT AN UPPER-LEVEL HIGH WILL REMAIN ACROSS THE SOUTHERN HALF OF THE NATION THROUGH THE EXTENDED PERIOD. AS A RESULT...EXPECT A FAIRLY STAGNANT PATTERN WITH HOT AND HUMID CONDITIONS LINGERING THROUGH EARLY NEXT WEEK. A WEAK COLD FRONT IS PROGGED TO SLOWLY SETTLE INTO THE TN RIVER VALLEY BY FRIDAY...AND THEN BECOME QUASI- STATIONARY THROUGH THE WEEKEND. WHILE THIS FRONTAL BOUNDARY WILL NOT PROVIDE MUCH TEMP RELIEF...IT WILL INCREASE THE CLOUD COVER AND AREAL COVERAGE OF CONVECTION DURING THE PERIOD...WHICH SHOULD RESULT IN A SLIGHT DECREASE OF A FEW DEGREES IN AFTERNOON MAXES. GFS AND ECMWF MODELS AGREE THAT ANOTHER STRONGER COLD FRONT WILL APPROACH THE FORECAST AREA ON MONDAY...WITH AN UNSEASONABLY STRONG UPPER- LEVEL TROUGH PUSHING IT ACROSS THE EASTERN HALF OF THE NATION. AS A RESULT...IT APPEARS THAT THIS NEXT COLD FRONT MAY ACTUALLY BRING COOLER TEMPS CLOSER TO NORMAL. WITH A MODERATELY UNSTABLE AIR MASS DEVELOPING EACH DAY THROUGH THE EXTENDED PERIOD OVER THE REGION... THINK THAT AT LEAST ISOLATED CONVECTION WILL BE POSSIBLE EACH DAY... ALONG WITH THE POSSIBILITY OF MORE-ORGANIZED MCS ACTIVITY FROM THE OHIO RIVER VALLEY ON A FEW DAYS. AS FOR TEMPS...WILL FOLLOW A PERSISTENCE PATTERN THROUGH THE EXTENDED PERIOD...BUT WITH A SLIGHT DECREASING TREND WITH MAXES DUE TO THE EXPECTED INCREASE IN CONVECTIVE DEVELOPMENT BY THE WEEKEND. && .PRELIMINARY POINT TEMPS/POPS...
