EVENT...HEAVY RAINFALL CONTINUES OVER A LARGE AREA FROM N IA/SE MN TO
S MI/NW OH
.
SATELLITE ANALYSIS AND TRENDS...ALTHOUGH CLOUD TOPS HAVE WARMED
DRAMATICALLY OVER THE LAST SEVERAL HOURS, HEAVY RAINFALL CONTINUES
OVER A LARGE AREA THIS MORNING FROM N IA/SE MN TO SE MI/NW OH.
RAINFALL RATES MORE THAN LIKELY MAXING OUT BETWEEN 0.3-0.6"/HR WITH
SOME ISOLATED LOCATIONS OVER 1.0"/HR FROM PVC TO RFD TO TOL.  HEAVIEST
RAINFALL DOES APPEAR AS THOUGH IT HAS SHIFTED SOUTH OF AN AREA WHERE
AUTOMATED SATELLITE ESTIMATES ARE RANGING FROM BETWEEN 3-5" ALONG AN
APPROXIMATE AREA FROM RENVILLE COUNTY IN SW MN TO COLUMBIA COUNTY IN
SW WI.  THE SHORT TERM CONCERN IS NOW BEGINNING TO SHIFT WESTWARD TO
CONVECTION THAT IS BEGINNING TO RAPIDLY FILL IN OVER N CNTRL AND NW IA.
HAVE NOTED A RAPID DECREASE IN CLOUD TOP TEMPS AND SUBSEQUENT INCREASE
IN RAINFALL RATES OVER AN AREA CNTRD BY MCW.  CONVECTION APPEARS TO BE
AT LEAST PARTIALLY AIDED BY SHORTWAVE TROF LIFTING NE OUT OF MO AND ALSO
BY DIVERGENT ENTRANCE REGION TO GREAT LAKES JET MAX.  CU FIELD APPEARS
TO BE DEEPENING UPWIND OF CURRENT CONVECTION OVER NW IA AND THIS RAISES
THE THREAT FOR REGENERATING/TRAINING CONVECTION ON THE SHORT TERM.
RAINFALL RATES OF 1-2"/HR ARE QUITE LIKELY OVER AT LEAST THE NEXT HOUR
FROM MCW TO CCY WHERE BAND INTERACTS WITH SWARD MOVING OUTFLOW BOUNDARY.
WILL CONTINUE MONITORING LEAD IMPULSE AHEAD OF ERIN TO SEE HOW DEVELOPING
RAINFALL OVER MO/IL INTERACTS WITH FRONTAL BOUNDARY.
