...PRECIPITATION...

MOSTLY LIGHT SNOW CONTINUED ACORSS THE NORTHERN PORTION OF THE
NCRFC REGION ACROSS NORTH DAKOTA TO MINNESOTA AND WISCONSIN
TO LOWER MICHIGAN...WHERE 24 HOUR SNOWFALL REPORTS WERE A COUPLE
INCHES OR LESS. SOME LAKE EFFECT SNOWS ALONG UPPER MICHIGAN AND
ALONG WESTERN AND NORTHERN LOWER MICHIGAN AVERAGED BETWEEN 2 AND
6 INCHES.  FARTHER SOUTH LIGHT SNOW ALSO CONTINUED SINCE YESTERDAY
MORNING ACROSS SOUTHERN MISSOURI TO SOUTHERN ILLINOIS WHERE
SNOWFALL REPORTS AVERAGED AROUND AN INCH OR LESS.  OVERALL LIQUID
CONTENT OF THE PRECIPITATION WAS LIGHT WITH TOTALS AROUND A TENTH
INCH OR LESS.

IN THE FORECAST...THE HEAVIER SNOW AMOUNTS WILL CONTINUE FOR LAKE
EFFECT SNOW AREAS ALONG UPPER AND LOWER MICHIGAN...WHILE LIGHT
SNOW WILL CONTINUE TO DRIFT ACROSS OUR REGION FROM SOUTHERN
MINNESOTA AND IOWA TO WISCONSIN AND NORTHERN ILLINOIS.  A QUARTER
TO HALF INCH IS EXPECTED NEAR SHORE AREAS OF MICHIGAN... WHILE A
TENTH INCH OR LESS IS EXPECTED ELSEWHERE.

...HYDROLOGIC CONDITIONS...
ANOTHER ROUND OF ARCTIC AIR IS SPREADING FROM THE NORTHERN GREAT
PLAINS ...TO THE GREAT LAKES REGION...AND SOUTHWARD ACROSS THE
UPPER MISSISSIPPI VALLEY...PRODUCING ADDITIONAL CHANNEL ICE IN
RIVERS AND STREAMS THROUGH THE REGION.  THE ICE PRODUCTION IS
CAUSING A DROP IN FLOWS ON MANY AREA RIVERS...AND WILL EVENTUALLY
CAUSE FLOWS IN THE MISSISSIPPI RIVER AT ST LOUIS TO DROP
DRAMATICALLY OVER THE NEXT FEW DAYS.

THE POTENTIAL FOR FREEZE-UP ICE JAMS WILL REMAIN ELEVATED OVER
THE NEXT FEW DAYS AS ICE FORMATION CONTINUES.
