Area forecast discussion, Jun 4, 9:45 AM EDT, 1 hour 14 minutes before
AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE KNOXVILLE/TRI-CITIES TN 945 AM EDT THU JUN 4 1998 KHTX AND KMRX 88DS SHOWING THUNDERSTORMS ENTERING EAST TN. SURFACE FRONT PROVIDING A FOCUS FOR ACTIVITY. BNA 12Z SOUNDING INDICATING VERY UNSTABLE CONDITIONS TODAY. SHORTWAVE EXPECTED TO PASS OVER EAST TN LATE THIS AFTERNOON...SO THINK LIKELY POPS FOR THUNDERSTORMS OVER THE ENTIRE CWA LOOKS GOOD FOR THE REST OF TODAY. MAY GET SOME BREAKS OF SUNSHINE THIS AFTERNOON AFTER THIS FIRST BATCH OF CONVECTION MOVES THROUGH...BUT CU WILL DEVELOP QUICKLY. TEMPERATURES SHOULD BE OK. RDU AND CRW...MAY WANT TO RAISE POPS TO 60% FOR TODAY. GH
