LIGHT PRECIPITATION WAS SCATTERED IN AND AROUND THE NORTHERN
PORTION OF THE NCRFC REGION DURING THE PAST 24 HOURS.
WATER EQUIVALENTS WERE GENERALLY A TENTH OF AN INCH OR LESS.

LITTLE OR NO PRECIPITATION IS EXPECTED FOR TODAY.

A DEVELOPING WEATHER SYSTEM MAY BRING A HALF INCH OR MORE OF
PRECIPITATION TO THE MISSISSIPPI RIVER DRAINAGE AND NEARBY
AREAS FROM LATE SUNDAY INTO TUESDAY. IT WILL MAINLY BE IN THE
FORM OF RAIN IN MISSOURI...ILLINOIS...AND IOWA...WHILE A MIXTURE
OF RAIN AND SNOW IS PREDICTED FURTHER NORTH.

NEARLY NORMAL TEMPERATURES FOR THIS TIME OF YEAR ARE EXPECTED INTO
NEXT WEEK.  AFTER CHRISTMAS...THOUGH...ARCTIC AIR IS EXPECTED TO
BEGIN A PUSH INTO THE DAKOTAS AND NORTHERN MINNESOTA AND BY THE
END OF THE MONTH REACH INTO IOWA AND WISCONSIN.  DAYTIME HIGHS
WILL ONLY REACH THE SINGLE DIGITS ABOVE ZERO.


...HYDROLOGIC CONDITIONS...
NO SIGNIFICANT FLOODING IS OCCURRING IN THE NCRFC FORECAST AREA
AND NONE IS FORECAST. ICE IS CAUSING LOCAL BACKWATER FLOODING
ON THE WOLF RIVER IN EASTERN WISCONSIN. WITH ANOTHER ROUND OF WARM
TEMPERATURES ABOVE FREEZING THIS WEEKEND...ICE JAM FLOODING
