Area forecast discussion, Jul 28, 2:25 PM EDT, 5 hours 11 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KNOXVILLE/TRI-CITIES TN 225 PM EDT MON JUL 28 1997 A WK MID LVL TROUGH MOVING THROUGH THE CWA WL ONLY ADD TO THE THREAT OF SVR WX FOR TNT. WINDEX VALUES AROUND 70 KTS ALONG WITH A MAX-MIN THETAE DIFFERENCE OF MORE THAN 30 DEGS WL KEEP THE PRIMARY THREAT AS DMGG WET MICROBURTS. AFTER THIS MID LVL TROUGH ALONG WITH THE PRE-FNTL TROUGH PUSHES EAST OF THE CWA BY MIDNIGHT OR SO...I EXPECT THE CHCS FOR CONVECTION TO DIMINISH SOMEWHAT. STILL WOULD NOT GET TOO FANCY WITH TIMING ESPECIALLY WITH THE REAL FNT STILL TO OUR NORTH. THUS WOULD BLANKET THE AREA WITH AT LEAST CHC POPS FOR TNT. THE COLD FNT IS PROGGED TO REACH SW VA BY MORNING AND THEN SLOWLY PUSH THROUGH THE REMAINDER OF THE CWA DURING THE DAY ON TUESDAY. SW VA AND NE TN MAY HAVE A LINGERING SHRA EARLY SO A SMALL POP WL STILL BE NEEDED HERE. WOULD GO WITH CHC FOR MOST AREAS EXCEPT GOOD CHC FOR SE TN AND SW NC. DUE TO THE PROXIMITY FO THE FNT ACROSS SE TN AND SW NC DURING THE LATE AFTN/EVE HOURS ON TUE WE WL NEED TO CONTINUE AT LEAST SMALL POPS FOR THIS RGN FOR THE EARLY PART OF THE THIRD PD. THE LOWER HUMIDITIES WL REALLY BEGIN TO MAKE ITS PRESENCE FELT TUE NIGHT AND CONTINUE THIS TREND INTO WED. A MUCH MORE COMFORTABLE AIRMASS WITH DEWPOINTS AND TEMPS AT LEAST TEN DEGS LOWER THAN TDA.
