Area forecast discussion, Jul 3, 2:31 PM EST, 1 hour 6 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 331 PM EDT TUE JUL 3 2012 .SHORT TERM (TONIGHT AND WEDNESDAY)...RADAR INDICATING SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A SHORTWAVE. WILL KEEP THE HIGHEST CHANCES FOR THE EVENING HOURS FOR TONIGHT. ANOTHER SHORTWAVE TRACKING THROUGH THE AREA BRINGING ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS. WILL KEEP THE HIGHEST CHANCES FOR THE AFTERNOON HOURS. TEMPERATURES SHOULD BE ABOVE NORMAL AGAIN...BUT NO RECORDS SHOULD BE BROKEN. GUIDANCE TEMPERATURES LOOKED REASONABLE...STAYED CLOSE. .LONG TERM (WEDNESDAY NIGHT THROUGH TUESDAY)...MODELS HAVE DIVERGED IN THEIR SOLUTIONS FROM THE PAST TWO MAJOR RUNS. THE GFS CONTINUES TO BE THE MOST PERSISTENT HOWEVER NAM HAS HANDLED PRECIPITATION BETTER. STILL SEEMS REASONABLE TO HAVE HIGH END CHANCE POPS ESPECIALLY OVER SW VIRGINIA AND NE TENNESSEE. WITH A LOT OF CONVECTION STILL DEVELOPING BY EARLY EVENING...EXPECTING THE ACTIVITY TO SLOWLY DISSIPATE BEFORE MIDNIGHT. THIS MAY INHIBIT THE CELEBRATION ACTIVITIES PLANNED FOR AFTER DARK. CERTAINLY NOT CLEAR CUT AND CONFIDENCE FROM YESTERDAY/S FORECAST IS SLIGHTLY LOWER. BOTH THE GFS AND NAM AGREE ON A MCS TYPE SYSTEM MOVING SOUTH TO SOUTHWEST OUT OF THE OHIO VALLEY WEDNESDAY NIGHT AND INTO THURSDAY. BOTH MODELS ARE BULLISH IN COVERAGE ACROSS THE FORECAST AREA AND A SYSTEM LIKE THIS COULD BRING BENEFICIAL RAINFALL TO THE REGION. THE GRIP OF THE UPPER HIGH BEGINS TO TAKE HOLD OF THE REGION ONCE AGAIN. THIS SHOULD PRODUCE WELL ABOVE NORMAL DAYTIME TEMPERATURE TRENDS AND LOWER RAINFALL CHANCES. THE FAVORED HIGHER TERRAIN OF EXTREME EASTERN TN LOOKS LIKE THE BETTER BET. LONGER RANGE MODELS STILL INDICATE A COLD FRONT APPROACHING THE FORECAST AREA SATURDAY NIGHT INTO SUNDAY. CONFIDENCE IS PRETTY HIGH THAT FOR RAINFALL ACROSS MUCH OF THE REGION SUNDAY AND MONDAY AS THE UPPER RIDGE BREAKS DOWN AND A COLD FRONT MOVES SOUTHWARD INTO AL/GA/SC AND NC. EXPECT THIS WEEKEND DAYTIME TEMPERATURES TO BE WELL ABOVE NORMAL...NEAR 100 DEGREES. && .PRELIMINARY POINT TEMPS/POPS...
