NORTHEAST ILLINOIS AND INTO MISSOURI. INFRARED SATELLITE IMAGERY
SHOWING VERY FEW CLOUDS ACROSS THE FORECAST AREA. HIGHER CLOUDS
SEEN STREAMING EASTWARD OUT ACROSS IOWA.

00Z MODELS INITIALIZED WELL. NO SIGNIFICANT DIFFERENCES ARE NOTED
WITH THE MODELS. AVN A LITTLE FASTER AT PUSHING PRECIPAITION INTO
THE AREA THIS AFTERNOON...BUT OTHERWISE ALL IN GOOD AGREEMENT.

AS SHORT WAVE ENERGY DIGS ACROSS THE ROCKIES TODAY...SURFACE

SATURDAY. COLDER AIR BECOMING DEEPER ACROSS AREA AND
CROSS SECTIONS CONTINUE TO INDICATE PROXIMITY OF THE MINUS 15C AND
MINUS 5C ISOTHERMS SUPPORTING POTENTIAL FOR GOOD DENDRITIC CRYSTAL

MIND WILL HOIST WARNINGS ACROSS THE SOUTH AND EAST FOR 5 TO 9
INCHES AND ADVISORIES JUST TO THE NORTH OF THE WARNING AREA FOR A
GENERAL 3 TO 5 INCH SNOWFALL. AS SYSTEM WRAPS UP WILL LIKELY HAVE
SOME STRONGER WINDS PRODUCING BLOWING AND DRIFTING OF THE SNOW AS
