NORTHEASTERN MINNESOTA, NORTHERN WISCONSIN, THE UPPER PENINSULA OF
MICHIGAN, AND SOUTHERN LOWER MICHIGAN.  UP TO A QUARTER INCH ALSO

AND RAIN ELSEWHERE.

DURING THE NEXT TWO DAYS WE ARE EXPECTING UP TO A HALF INCH OF RAIN

HIGHER THAN NORMAL TEMPERATURES ARE EXPECTED ACROSS THE NORTH
CENTRAL U.S. THROUGH MID NEXT WEEK WHEN TEMPERATURES WILL FALL
BELOW FREEZING OVER MUCH OF THE NCRFC SERVICE AREA FOR AWHILE.

...HYDROLOGIC CONDITIONS...

WATER LEVELS REMAIN ELEVATED FROM ICE JAMS ON AREA RIVERS.
MAJOR FLOODING IS OCCURRING ON THE MISSISSIPPI RIVER NEAR
BURLINGTON, IOWA DUE TO AN ICE JAM.

MODERATE ICE JAM FLOODING CONTINUES ON THE IOWA RIVER NEAR
MARENGO.

RAINFALL OVER THE PAST FEW DAYS, ICE JAMS, FORECAST RAINFALL,
AND ONGOING AND FORECAST SNOWMELT HAS CAUSED THE ROCK RIVER NEAR
MOLINE, ILLINOIS, TO RISE ABOVE MAJOR FLOOD LEVELS BUT HAS NOW
JUMPED BELOW MODERATE FLOODING. UPSTREAM OF MOLINE, THE ROCK RIVER
AT JOSLIN HAS DROPPED SHARPLY FROM NEAR MAJOR FLOODING.

THE SITUATION MENTIONED ABOVE HAS ALSO EFFECTED MUCH OF THE NCRFC
AREA EXCEPT THE MORE NORTHERN AREAS AND CONSEQUENTLY MINOR FLOODING
WILL CONTINUE TO BE WIDESPREAD FOR SOME TIME.
