AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KNOXVILLE/TRI-CITIES TN 820 PM EDT SAT MAY 31 1997 MRX WSR-88D IS SHOWING A LARGE AREA OF SHOWERS AND THUNDERSTORMS MOVING NORTH ACROSS THE PLATEAU...SOUTHEAST TENNESSEE...SOUTHWEST NORTH CAROLINA...AND CENTRAL TENNESSEE VALLEY. SOME OF THE RAIN HAS BEEN QUITE HEAVY WITH THE CHA ASOS REPORTING OVER 1.6 INCHES OF RAIN DURING THE PAST 3 HOURS. THE AREA OF RAIN IS HAVING A HARD TIME MOVING NORTHEAST INTO NORTHEAST TENNESSEE AND SOUTHWEST VIRGINIA. BELEIVE THE AREA OF RAIN WILL EVENTUALLY MOVE INTO THESE AREAS LATER THIS EVENING. HOWEVER...MRX VWP IS SHOWING WEAK- MODERATE SOUTHEAST WINDS INTO THE NORTHEAST SECTIONS OF THE FORECAST AREA WHICH WILL KEEP PCPN AMOUNTS DOWN CONSIDERABLY DUE TO DOWNSLOPE WINDS. I DO NOT FEEL NORTHEAST TENNESSEE OR SOUTHWEST VIRGINIA WILL EXPERIENCE ANY RUNOFF PROBLEMS DUE TO THE DOWNSLOPE FLOW. GREATEST THREAT FOR FLASH FLOODING WILL BE ACROSS THE PLATEAU AND SOUTHEAST TENNESSEE DUE TO THE PERSISTENT LO LVL CONVERGENCE... UPSLOPE FLOW...AND MAX UPR DIFL. CURRENT TEMP FCST LOOKS GOOD...BUT WOULD RECOMMEND CHGG WIND FCST TO VARIABLE FOR CHA AND CSV AREAS. WATER VAPOR LOOP SHOWS A WELL DEFINED DRY SLOT WRAPPING EAST NORTHEAST ACROSS MS INTO AL. ETA MODEL SHOWS THIS MID-LVL DRYING MOVING INTO THE FORECAST AREA FOR SUNDAY. FEEL SHOWER AND STORMS WILL DIMINISH OVER THE REGION IN THE MORNING WITH SKIES BECOMING BRIEFLY PARTLY CLOUDY AROUND NOON TOMORROW.

I STG/SVR STMS TO DEVELOP OVER THE REGION BY MID/LATE AFTERNOON WITH MAIN THREAT BEING DAMAGING DOWNBURSTS WINDS AND LARGE HAIL. FEEL MIDNIGHT SHIFT WILL NEED TO CONSIDER RAISING POPS FOR SUNDAY AND INCLUDING POSSIBLY SVR IN THE FCST.
