...PRECIPITATION...

A MIXED BAG OF RAIN AND SNOW FELL ACROSS THE NCRFC AREA YESTERDAY
AND LAST NIGHT...THE BULK OF IT MOVING FROM MISSOURI INTO
ILLINOIS ...INDIANA...AND SOUTHERN LOWER MICHIGAN. HIGHEST RAIN
AMOUNTS WERE AROUND 1.5 INCHES...WHICH FELL FROM EAST-CENTRAL
MISSOURI INTO CENTRAL AND SOUTHERN ILLINOIS.

THE STORM SYSTEM THAT AFFECTED THE REGION YESTERDAY IS EXPECTED
TO EXIT EAST TODAY...POSSIBLY DROPPING A FEW INCHES OF SNOW IN
THE DETROIT AREA AS IT GOES BY.

COLDER TEMPERATURES HAVE MOVED BACK INTO THE REGION TODAY...WITH
HIGHS JUST IN THE 20S AND 30S FOR THE MOST PART. WARMING WILL
COME AGAIN TOMORROW...BUT THEN ANOTHER SHOT OF COLD AIR IS
FORECAST TO MOVE IN OVER THE WEEKEND.

...HYDROLOGIC CONDITIONS...

IN CENTRAL TO SOUTHERN IOWA AND ILLINOIS MUCH OF THE SNOW PACK
HAS MELTED OFF CREATING WIDSPREAD MINOR FLOODING. A COUPLE OF
WARMER DAYS STARTING TOMORROW COULD ADD A FEW MORE LOCATIONS
IN NORTHERN IOWA AND ILLINOIS TO THE FLOODING MIX AS THE SNOW
MELTS.

AREAS OF NORTH OF THESE LOCATIONS STILL HAVE RETAINED THE SNOW
PACK AND WILL CONTINUE TO RIPEN IN THE COMING DAYS WITH THE
EXPECTATION OF DAY MELT AND NIGHT FREEZING AT LEAST FOR SOUTHERN
MINNESOTA...SOUTHERN WISCONSIN AND SOUTHERN MICHIGAN.

EVEN IN LOCATIONS WHERE THE SNOWPACK HAS COMPLETELY MELTED SUCH AS
MARENGO IOWA SERIOUS RIVER ICE STILL EXISTS. ICE JAMS WILL CONTINUE
TO BE A SERIOUS THREAT AS RUNOFF BEGINS AND TEMPERATURES FLUCTUATE.
