Area forecast discussion, Jun 13, 9:36 AM EDT, 5 hours 15 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 935 AM EDT SAT JUNE 13 1998 WBC...MAY WANT TO LOWER RANGE FOR MAXS TODAY TO MU80S FOR THE ROA GRP BASED ON COOLER H8 TEMPS AND MORNING SOUNDINGS. MIXING TO NEAR FRIDAYS DEPTH WOULD GIVE ROA 85ISH. CRW...STILL COULD SEE A FEW TSTMS IN THE NRV THIS AFTERNOON...BUT THINK PARTLY SUNNY BETTER THAN CLOUDY. CC OR VC SEEMS GOOD FOR SERN WV AND MOUNTAIN EMPIRE OF VA. RDU...PARTLY SUNNY SEEMS BETTER FOR NW NC WITH THE SCATTERED CONVECTION. DISCUSSION... 88D INDICATING MOST OF THE SHOWERS WEAKENING ATTM...EXCEPT FOR NEW BATCH OF THUNDER FORMING IN EASTERN TN AND MOVING INTO WATAUGA COUNTY. SAT PIX HAS PLENTY OF HOLES IN IT OVER THE CWA. LOW LEVEL CLOUDS IN ERN KY AND CENTRAL AND WESTERN WV SPREADING EASTWARD IN WESTERLY FLOW AND WILL LIKELY KEEP UPSLOPE COUNTIES IN SERN WV AND PERHAPS SMYTH/TAZEWELL COUNTIES IN LOTS OF CLOUDS FOR THE AFTERNOON...LIMITING CHANCES FOR ORGANIZED OR STRONG CONVECTION THERE. FARTHER TO THE EAST...STILL SOME QUESTIONS. WHILE WESTERLY FLOW MAY DAMPEN CONVECTION CHANCES IN THE VA FOOTHILLS AND WESTWARD...FARTHER EAST AND SOUTH INTO NC...HIGH DEWPOINTS AND AIRFLOW RECOVERING FROM SHARPER DOWNSLOPING TO THE WEST..WE MAY STILL SEE STRONG CONVECTION CONVECTION INTO EARLY THIS AFTERNOON BEFORE BEST DYNAMICS PASS TO THE EAST BY LATE LATE IN THE AFTERNOON. FINAL THOUGHT...H8 TEMPS AND MIXING DEPTH FROM FRIDAY SUGGESTING THAT U80S MAY BE A LONG SHOT FOR ROA/LYH GRPING. NOGUEIRA

THE AREA MOST SUSCEPTABLE TO SEVERE THUNDESTORMS IS SOUTHEAST OF A LINE FROM LYNCHBURG TO MARTINSVILLE IN VIRGINIA...TO YADKINVILLE IN NORTH CAROLINA. THE GREATEST SEVERE WEATHER THREAT FROM THUNDERSTORMS IN THIS AREA IS DAMAGING WINDS. A MODERATELY UNSTABLE AIRMASS...COMBINED WITH AN UPPER LEVEL DISTURBANCE AND AN APPROACHING COLD FRONT WILL TRIGGER SCATTERED THUNDERSTORMS ACROSS THE REGION DURING THE AFTERNOON. THE ATMOSPHERE IS MOST UNSTABLE IN THE PIEDMONTS OF VIRGINIA AND NORTH CAROLINA WHERE STRONG WINDS IN THE MID LEVELS OF THE ATMOSPHERE MAY AID THUNDERSTORMS IN PRODUCING DAMAGING WINDS. FARTHER TO THE NORTHWEST COLDER AIR IS ARRIVING IN THE HIGHER LEVELS OF THE ATMOSPHERE. WHILE THE POTENTIAL FOR SEVERE THUNDERSTORMS WEST OF THE BLUE RIDGE IS SOMEWHAT LESS...THE POTENTIAL EXISTS FOR ISOLATED STORMS TO PRODUCE DAMAGING WIND GUSTS AND LARGE HAIL.
