CONCERNING...SEVERE THUNDERSTORM WATCH 258...

VALID 152052Z - 152145Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 258
CONTINUES.

SUMMARY...MCS MOVING SEWD ACROSS WRN KY INTO NWRN TN WILL CONTINUE
TO POSE A DMGG WIND THREAT AS IT MOVES SEWD ACROSS WW 258. TRENDS
WILL BE MONITORED OVER THE NEXT 1-2 HRS FOR POSSIBLE NEW WW ISSUANCE
DOWNSTREAM FROM THE MCS.

DISCUSSION...MCS EXTENDS FROM JUST E OF THE MS RIVER ALONG THE TN/KY
BORDER TO JUST E OF CKV...NNEWD TO THE LOWER OH VALLEY AS OF
2030Z...AND IS PROGRESSING SEWD AT AROUND 30 KT. SEVERAL REPORTS OF
ESTIMATED MARGINALLY SVR WIND GUSTS AND TREES DOWN HAVE BEEN
RECEIVED...AND LATEST BASE VELOCITY RADAR DATA CONTINUES TO SUGGEST
POTENTIAL FOR STRONG TO LOCALLY SVR WIND GUSTS. A MOISTURE-RICH AND
UNSTABLE AIR MASS REMAINS IN PLACE IMMEDIATELY DOWNSHEAR FROM THE
MCS...WHICH WILL SPREAD ACROSS MIDDLE TN /INCLUDING THE NASHVILLE
METRO AREA/ WITHIN THE NEXT 1-2 HRS. SLIGHTLY COOLER TEMPERATURES
EXIST ACROSS ERN PORTIONS OF WW 258 OWING TO EARLIER CLOUD
COVER...BUT THIS AREA CONTINUES TO DESTABILIZE AMIDST STRONG
HEATING. MORE RECENT ISOLATED TSTM DEVELOPMENT ALONG THE NRN/SRN
FRINGE OF THE MCS ACROSS CNTRL KY AND SRN TN MAY ALSO PRODUCE A
LOCALLY DMGG WIND THREAT OVER THE NEXT COUPLE HRS.

AS THE MCS AND PRECEDING ISOLATED TSTMS APPROACH THE SRN/ERN EDGES
OF WW 258...A NEW WW MAY NEED TO BE CONSIDERED PENDING FAVORABLE
CONVECTIVE TRENDS.
