...SUMMARY...
THE POTENTIAL FOR SEVERE THUNDERSTORMS WILL EXTEND FROM THE CENTRAL
GULF COAST TO THE LOWER GREAT LAKES REGION ON WEDNESDAY INTO
WEDNESDAY NIGHT. THE GREATEST POTENTIAL FOR SEVERE THUNDERSTORMS IS
FORECAST FROM PORTIONS OF THE MID-SOUTH REGION TO THE TENNESSEE
VALLEY...WHERE TORNADOES...SOME SIGNIFICANT...ALONG WITH DAMAGING
WINDS AND HAIL WILL BE POSSIBLE.
...DISCUSSION...
STRONG HIGH-LEVEL FLOW IS FORECAST TO TRANSLATE ALONG A CORRIDOR
FROM THE GREAT BASIN...INTO THE BASE OF CNTRL U.S. TROUGH OVER
TX...THEN NEWD INTO THE GREAT LAKES EARLY IN THE PERIOD. FOCUSED
12HR MID-LEVEL HEIGHT FALLS WILL SHIFT FROM KS/OK INTO THE UPPER
GREAT LAKES BY LATE AFTERNOON AS SFC CYCLONE SHIFTS FROM NERN KS
INTO THE U.P. OF MI. IN RESPONSE TO THIS LARGE-SCALE
ADJUSTMENT...STRONG WARM ADVECTION WILL BE RESPONSIBLE FOR LATE DAY1
INTO EARLY DAY2 CONVECTION ACROSS MUCH OF THE GULF STATES AND
MID-SOUTH REGION. THIS EARLY PERIOD TSTM ACTIVITY WILL INHIBIT
DESTABILIZATION WITHIN BROADER RECOVERY PORTIONS OF THE OH/ERN TN
