Area forecast discussion, Jun 28, 2:50 PM EDT, 1 hour 48 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KNOXVILLE/TRI-CITIES TN 248 PM EDT SAT JUN 28 1997 SHORT-TERM...RATHER UNEXPECTED PLAYERS IN TODAY'S CONVECTION HAVE BEEN WELL-DEFINED OUTFLOW BOUNDARIES WHICH INCREASED COVERAGE ESPECIALLY OVER PLATEAU COUNTIES. ADAP HAS ALSO SHOWN CONVERGENCE IN SMOKIES AND EXTRM SRN MTNS INTO CLAY AND CHEROKEE COUNTIES. PLATEAU STORMS MOVING EVER SO SLOWLY EWD WHILE ELSW STORMS APPR NEAR STNRY. ISOLD RW/TSTMS EVEN INTO SWRN VA COUNTIES ATTM. FWC POPS COULD BE A BIT TOO HIGH IN FEW AREAS FOR TNGT...BUT WITH WEAK SHRTWV CONTG TO APCH...WILL NEED AT LEAST HIGH CHC POPS. AGREE WITH CRW PER COORD CALL ON 40% POPS STILL GOOD FOR TNGT. STORMS HAVE BRIEFLY PULSED BUT SEEM TO HAVE TROUBLE MAINTAINING ANY SIGNIFICANT INTENSITY...WHICH MAKES SENSE GIVEN SUCH WEAK WINDS ALOFT. SEEMS TO ME MORE OF A FLASH FLOOD THREAT GIVEN SLOW MOVMT AND HIGH PRECIPTBL WATER VALUES. LATER PERIODS...ALREADY READ RDU SFD AND JUST COORDINATED WITH MEM. SEEMS BEST BET TO GO OVERALL WITH WETTER NGM SOLUTION AND HIGHER POPS. EXCEPTION WOULD BE SWRN VA AND EXTRM NE TN ZONES...WHERE DRIER ETA MDL AND LOWER FAN POPS LOOK BEST. OTRW...CAN'T ARGUE WITH HIGH CHC TO LIKELY dPOPS GIVEN INCRSG MOISTURE/INSTBY...UPSLOPE INTO MTNS AND CONTD TRACK OF AT LEAST WEAK SHRTWVS THRU MON. FOR TEMPS...I WOULD GO CLOSER TO WARMER FWC ON BOTH MAXES AND MINS. TG/10
