THE SURFACE LOW OVER IOWA WILL CONTINUE TO LIFT NORTHWARD THROUGH
THE UPPER MIDWEST ON TUESDAY. PLENTY OF WARM MOIST GULF AIR IN
PLACE WILL ALLOW MODERATE TO HEAVY RAINS TO CONTINUE TO DEVELOP
AHEAD AND ALONG THE SLOW MOVING COLD FRONT. BY TUESDAY
EVENING...ANOTHER WAVE OF LOW PRESSURE IS EXPECTED TO DEVELOP
ALONG THE TRAILING FRONT OVER THE SOUTHERN PLAINS. THIS SECOND
LOW WILL AGAIN ENHANCE PRECIPITATION AND TRIGGER SEVERE
THUNDERSTORMS AHEAD/ALONG THE FRONT. HOWEVER...AS THIS SECOND LOW
STRENGTHENS AND MOVES INTO THE OHIO VALLEY...IT WILL PUSH THE
ASSOCIATED COLD FRONT AND HEAVY RAINS EASTWARD...AWAY FROM THE
RAIN SOAKED REGIONS OF THE LOWER/MIDDLE MISSISSIPPI AND OHIO
VALLEYS. PRECIPITATION ACROSS THESE AREAS SHOULD FINALLY COME TO
AN END BY THURSDAY MORNING. ADDITIONAL RAINFALL AMOUNTS OF 2 TO 4
INCHES ARE LIKELY ACROSS THE OHIO...TENNESSEE...AND LOWER
MISSISSIPPI RIVER VALLEYS....WITH ADDITIONAL AMOUNTS EXCEEDING 5
INCHES POSSIBLE FROM EASTERN ARKANSAS NORTHEASTWARD TO SOUTHERN
INDIANA. GIVEN THE ALREADY SATURATED GROUND AND SWOLLEN
RIVERS...SERIOUS FLOODING ISSUES WILL REMAIN A CONCERN.
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.
