...PRECIPITATION...

SCATTERED SHOWERS AND THUNDERSTORMS CONTINUED TO DEVELOP JUST
WEST OF THE NCRFC REGION.  SINCE YESTERDAY MORNING TWO TO FOUR
INCHES OF RAIN FELL IN MAINLY SOUTHWEST IOWA... BUT WITHIN NCRFC
BASINS ALONG WESTERN IOWA RAINFALL AMOUNTS WERE IN THE HALF TO ONE
INCH RANGE.  ALSO A FEW AREAS OF SCATTERED THUNDERSTORMS PRODUCED
ONE TO TWO INCHES OF RAIN IN EAST CENTRAL MISSOURI TO CENTRAL AND
SOUTHERN ILLINOIS.

IN THE FORECAST TODAY... A LARGE AREA OF ONE TO TWO INCH AVERAGE
RAINFALL WILL SPREAD SLOWLY EAST AND NORTH ACROSS OUR REGION...
FROM IOWA TO SOUTHERN MINNESTOA AND ACROSS WISCONSIN.  LOCALLY
HIGHERAMOUNTS IN THE TWO TO FOUR INCH RANGE ARE EXPECTED IN THIS
AREA WHERE BANDS OF HEAVIER CONVECTION DEVELOP. THEN FOR THE NEXT
COUPLE OF DAYS RAIN ASSOCIATED WITH THIS SLOW MOVING STORM SYSTEM
WILL CONTINUE TO DRIFT OVER FROM MINNESOTAN AND IOWA TO WISCONSIN
AND MICHIGAN...BRINGING 2 TO 4 INCHES TOTALS FOR MUCH OF OUR REGION.

...HYDROLOGIC CONDITIONS...

EXPECTED TO REMAIN ABOVE FLOOD STAGE FOR AT LEAST THE NEXT WEEK.

ALL OTHER RIVERS AND STREAMS IN THE NCRFC AREA ARE CURRENTLY BELOW
FLOOD STAGE.  THE RACCOON RIVER NEAR DES MOINES... IOWA... HAS THE
POTENTIAL TO REACH FLOOD STAGE IN THE NEXT FEW DAYS WITH THIS MORNING`S
24 HOUR RAINFALL FORECAST... HOWEVER... THE FORECAST RAINFALL AMOUNTS
AND PLACEMENT ARE STILL UNCERTAIN AND THE SITUATION WILL BE EVALUATED
AGAIN LATER TODAY.

FLOODING WITH THE 24 HOUR FORECAST RAINFALL.  HOWEVER... THAT MAY
CHANGE AS PRECIPITATION IS EXPECTED TO FALL IN THE NCRFC AREA FOR AT
