...PRECIPITATION...
OVER THE PAST 24 HOURS...THE BULK OF THE PRECIPITATION THAT FELL
WAS IN LOWER MICHIGAN AND FAR NORTHERN INDIANA. IT WAS MOSTLY
RAIN...BUT SOME SNOW MIXED IN OCCASIONALLY. AMOUNTS RANGED
FROM 0.50 TO 0.75 INCH IN THE SOUTH AND WEST TO AROUND AN INCH
OR SO IN THE EAST AROUND AND NORTH OF DETROIT.

FOR THE NEXT 24 HOURS...LITTLE OR NOR PRECIPITATION IS
EXPECTED...MAYBE JUST A FEW LIGHT SNOW FLURRIES FALLING FROM
EASTERN SOUTH DAKOTA INTO PARTS OF MINNESOTA.

TEMPERATURES WILL GRADUALLY GET COLDER AND COLDER FROM TODAY
INTO THE END OF THE YEAR AS ARCTIC AIR PUSHES ITS WAY
SOUTHWARD INTO THE UPPER MIDWEST.


...HYDROLOGIC CONDITIONS...
RIVERS ARE ON THE RISE AND AT UNSEASONABLY HIGH FLOW LEVELS
ACROSS EASTERN ILLINOIS...NORTHERN INDIANA AND MICHIGAN.  A FEW
RIVERS IN LOWER MICHIGAN ARE FORECAST TO CREST NEAR TO SLIGHTLY
ABOVE FLOOD STAGE.

THE POST CHRISTMAS ARCTIC AIR INTRUSION MAY LEAD TO A FRAZIL ICE
FORMATION SITUATION WITH THESE HIGHER FLOW LEVELS WE ARE
EXPERIENCING.  RIVERS IN THE NORTHERN PORTION OF THE AREA SHOULD
BE MONITORED FOR FREEZE UP JAM FORMATION.
