Area forecast discussion, Jun 2, 2:30 AM EDT, 3 hours 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KNOXVILLE/TRI-CITIES TN 230 AM EDT TUE JUN 2 1998 INTERESTING FCST THIS MRNG. ON THE SURFACE THE FCST LOOKS FAIRLY SIMPLE...HOWEVER...AFTER LOOKING FURTHER...FCST BECOMES COMPLICATED AND POTENTIALLY SEVERE AND BRINGS UP CONCERNS ABOUT ADDITIONALLY FLASH FLOODING PROBLEMS. FIRST S/WV IN FAST WESTERLY FLOW IS MOVING ACROSS THE OHIO/TENNESSEE VALLEYS AT THIS TIME INCREASING THE ISENTROPIC LIFT/WAA OVER REGION EARLY THIS MORNING. PER SPS DISC...WIND PROFILES ACROSS THE WESTERN TENNESSEE VALLEY IS FAVORABLE FOR SVR STORMS THIS MRNG. THIS ACTIVITY WILL MOVE INTO THE CWA LATER THIS MRNG. S/WV WILL MOVE EAST OF THE AREA BY MID-MORNING...BUT ANOTHER COLD FRONT WILL APPROACH THE AREA LATE THIS AFTERNOON AND EVENING. SINCE BOUNDARY WINDS WILL BECOME SW-W A DRASTIC INCREASE IN BOUYANCY CAN BE ANTICIPATED OVER THE REGION WITH CAPES INCREASING TO 3000 J/G PLUS AND LIFTED INDICES OF -8 TO -10. I ANTICIPATE REDEVELOPMENT OF SCT THUNDERSTORMS BY LATE THIS AFTERNOON THROUGH THE EVENING. DUE TO THE FCST SOUNDING SHOWING DRY MID-LEVELS AND INVERTED-V BOUNDARY LAYER CONFIGURATION...SOME OF THE STORMS COULD PRODUCE DAMAGING STRAIGHT LINE WINDS. COLD FRONT WILL BECOME STATIONARY OVER THE CWA TONIGHT AND WEDNESDAY. WIDELY SCT-SCT CONVECTION WILL REMAIN POSSIBLE DUE TO THE PROXIMITY OF THE FRNT TONIGHT...HOWEVER...GRIDDED DATA IS SHOWING THE POTENTIAL OF WIDESPREAD CONVECTION FOR WEDNESDAY. DECENT LO LVL CONVERGENCE ALONG FRNT...HIGH CAPES/INSTABILITY/AND PRESENCE OF MODERATLY-STG UPPER DIV OVER THE AREA DUE TO LOCATION OF RIGHT REAR QUAD OVER THE AREA SUGGEST LIKELY CHCS OF THUNDERSTORMS FOR WEDNESDAY AFTERNOON/EVENING. PWS ARE PROGGD TO BE AROUND 1.5-1.6 INCHES AND 850 MB DEWPOINTS OF 15 DEGREES...SO ABUNDANT MOISTURE FOR TORRENTIAL RAINS WITH THE STORMS WEDNESDAY. ALSO...STORM MOTION WILL BE PARRALLEL TO FRONT WHICH WILL GIVE THE THREAT FOR TRAINING OF CELLS WEDNESDAY AFTERNOON/EVENING. AGAIN SVR WEATHER WILL ONCE AGAIN BE A CONCERN FOR WEDNESDAY GIVEN THE EXPECTED HIGH CAPES AND WATER LOADING OF THE STORMS PRODUCING DAMAGING WINDS AND POSSIBLY LARGE HAIL. WOULD SUGGEST GOING ABOVE GUIDANCE POPS FOR WEDNESDAY. LATER SHIFTS WILL HAVE TO WATCH FOR THIS POTENTIAL. AS FOR TEMPS WOULD RECOMMEND FOLLOWING THE FWC NOS... DH
