OF SEVERE THUNDERSTORMS.  BY THURSDAY MORNING...ADDITIONAL
RAINFALL TOTALS OF 2 TO 7 INCHES ARE EXPECTED ACROSS MUCH OF THE
LOWER/MIDDLE MISSISSIPPI...OHIO...AND TENNESSEE RIVER
VALLEYS...WITH LOCALIZED HIGHER AMOUNTS POSSIBLE.  GIVEN THE

ISSUES ARE ARE A CONCERN.

THE NEXT STORM SUMMARY WILL BE ISSUED BY THE HYDROMETEOROLOGICAL
PREDICTION CENTER AT 400 AM CDT. PLEASE REFER TO YOUR LOCAL
