THE FRONTAL BOUNDARY ACROSS THE OHIO AND MISSISSIPPI RIVER VALLEY
WILL MOVE SLOWLY EASTWARD...BRINGING SHOWERS AND THUNDERSTORMS TO
MUCH OF THE EASTERN U.S. THROUGH MIDWEEK. THE SLOW MOVEMENT OF THE
SOUTHERN PORTION OF THE BOUNDARY WILL ALLOW THE POTENTIAL FOR
HEAVY RAIN TO PERSIST THROUGH TUESDAY ACROSS ALREADY SATURATED
AREAS OF THE MISSISSIPPI AND OHIO RIVER VALLEYS. ADDITIONAL
RAINFALL AMOUNTS OF 2 TO 3 INCHES...WITH LOCALLY HIGHER
AMOUNTS...CAN BE EXPECTED ACROSS PORTIONS OF THE MISSISSIPPI AND
OHIO RIVER VALLEYS THROUGH TUESDAY EVENING. MANY STREAMS AND
RIVERS ACROSS THE REGION ARE ALREADY EXPERIENCING MAJOR
FLOODING...AND RECORD FLOODING IS FORECAST TO OCCUR AT SOME
LOCATIONS. PLEASE REFER TO PRODUCTS FROM NATIONAL WEATHER SERVICE
LOCAL WEATHER FORECAST OFFICES FOR SPECIFIC DETAILS ON FLOODING IN
YOUR AREA.

THE NEXT STORM SUMMARY WILL BE ISSUED BY THE HYDROMETEOROLOGICAL
PREDICTION CENTER AT 1000 AM CDT. PLEASE REFER TO YOUR LOCAL
NATIONAL WEATHER SERVICE OFFICE FOR ADDITIONAL INFORMATION ON THIS
EVENT.
