CONCERNING...TORNADO WATCH 60...
VALID 232357Z - 240130Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 60 CONTINUES.
SUMMARY...A CONCENTRATED CORRIDOR OF SUPERCELLS IS EXPECTED ACROSS
PORTIONS OF THE MID-SOUTH THIS EVENING.
DISCUSSION...LLJ IS SHIFTING SOUTHEAST EARLY THIS EVENING ALONG THE
SOUTHERN FRINGE OF A TROUGH THAT IS SHIFTING TOWARDS THE LOWER OHIO
VALLEY. LARGE-SCALE SYNOPTIC FRONT IS EXPECTED TO ADVANCE ACROSS
WESTERN KY/TN/EASTERN AR, BUT PRE-FRONTAL CONFLUENCE APPEARS TO BE
AIDING SCATTERED-NUMEROUS ROBUST UPDRAFTS, INCLUDING SUPERCELLS,
ALONG A CORRIDOR FROM SOUTHEAST AR-NORTHERN MS-NORTHWEST AL. MOST OF
THE LONGER-LIVED UPDRAFTS ARE PRODUCING HAIL AND THIS SHOULD
CONTINUE INTO THE MID-EVENING HOURS. ADDITIONALLY, FORECAST
SOUNDINGS SUGGEST SOME TORNADO RISK WHERE DEW POINTS HAVE RISEN INTO
THE LOWER 60S, AS SBCAPE IN THIS ENVIRONMENT IS FAIRLY SUBSTANTIAL
WITHIN A STRONGLY SHEARED ENVIRONMENT. WITH TIME THIS CORRIDOR IS
EXPECTED TO GRADUALLY SAG SOUTHEAST.
