HYDROMETEOROLOGICAL FORECAST DISCUSSION
NWS NORTH CENTRAL RIVER FORECAST CENTER TWIN CITIES/CHANHASSEN MN
1055 AM CST THU DEC 12 2013

...PRECIPITATION...

IN THE PAST 24 HOURS... A LIGHT WAVE OF SNOW MOVED DOWN FROM NORTH
DAKOTA... ACROSS NORTHERN MINNESOTA AND WISCONSIN WITH SNOWFALL
TOTALS GENERALLY LESS THAN AN INCH... AND WATER EQUIVALENTS OF A
FEW HUNDREDTHS.  THERE WAS ALSO CONTINUED LAKE EFFECT SNOW IN
WESTERN AND NORTHERN LOWER MICHIGAN... AND THE NORTHERN COAST OF
THE UPPER PENINSULA.  SNOWFALL MAXED OUT AROUND SIX INCHES AND A
QUARTER INCH OF WATER EQUIVALENT.

FOR TODAY... CONTINUED COLD TEMPERATURES AND MINIMAL SNOWFALL...
WITH THE SAME SETUP FOR LAKE EFFECT SNOWS. THIS WEEKEND WILL SEE A
SLIGHT WARM-UP FOR SOUTHERN ILLINOIS AND SOUTHERN MISSOURI...
ACCOMPANIED BY A WINTRY MIX OF PRECIPITATION DROPPING OVER A HALF
INCH OF WATER.

...HYDROLOGIC CONDITIONS...

ANOTHER ROUND OF ARCTIC AIR HAS SPREAD 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 THIS EFFECT IS
BEING SEEN IN THE CONTINUALLY DROPPING LEVELS DOWN SOUTH ON
THE MISSISSIPPI RIVER AT ST LOUIS.

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