NORTHWEST AND WEST CENTRAL ILLINOIS...AND NORTHEAST MISSOURI.

.DAY ONE...TONIGHT THROUGH SATURDAY MORNING...

FREEZING RAIN MIXED WITH SLEET WILL BE POSSIBLE LATE TONIGHT AND
EARLY SATURDAY MORNING ALONG AND NORTH OF HIGHWAY 30.  THE
FREEZING RAIN COULD CAUSE SOME MINOR ICE ACCUMULATIONS AND CREATE
SLIPPERY DRIVING CONDITIONS.  THE WINTRY MIX IS EXPECTED TO MOVE
INTO EAST CENTRAL IOWA AROUND 3 AM THEN SPREAD QUICKLY
EAST...REACHING NORTHWEST ILLINOIS AROUND 6 AM.  THE FREEZING RAIN
AND SLEET WILL CHANGE TO LIGHT SNOW SATURDAY MORNING BEFORE ENDING.

DENSE FOG MATERIALIZES...IT SHOULD NOT LAST MUCH PAST MIDNIGHT.

A FAST MOVING LOW PRESSURE SYSTEM WILL MOVE OUT WESTERN NEBRASKA
THIS EVENING AND ALONG THE IOWA MISSOURI BORDER OVERNIGHT...
REACHING THE SOUTHERN GREAT LAKES BY NOON SATURDAY.  THE SNOW COVER
OVER EASTERN IOWA AND NORTHWEST ILLINOIS WILL HELP KEEP
TEMPERATURES AT OR BELOW FREEZING TONIGHT.  MEANWHILE THE STORM
WILL PULL A LAYER OF WARM AIR NORTH OVERSPREADING THE COLD SURFACE
TEMPERATURES...SETTING UP AN IDEAL SCENARIO FOR FREEZING RAIN.  SINCE
THE SYSTEM WILL MOVE THROUGH THE REGION QUICKLY...IT WILL LIMIT
PRECIPITATION AMOUNTS.  IF THE STORM INTENSIFIES MORE THAN
EXPECTED OR SLOWS DOWN...THEN MORE SIGNIFICANT ICING WILL OCCUR
AND WINTER WEATHER ADVISORIES MAY BE NEEDED.

.DAYS TWO THROUGH SEVEN...SATURDAY AFTERNOON THROUGH FRIDAY...

AN ARCTIC COLD FRONT WILL PUSH THROUGH THE REGION ON SATURDAY...
BRINGING A RETURN OF COLD TEMPERATURES THAT WILL LINGER THROUGH
THE MIDDLE PART OF NEXT WEEK. THIS FRONT WILL BECOME STATIONARY
ACROSS THE CENTRAL PLAINS WITH A SERIES OF FAST MOVING DISTURBANCES
BRINGING CHANCES FOR PRECIPITATION TO THE OUTLOOK AREA MONDAY
THROUGH WEDNESDAY. THE BEST CHANCE FOR MEASURABLE PRECIPITATION WILL
BE MONDAY IN THE FORM OF SNOW AND POSSIBLY SLEET. EARLY INDICATIONS
ARE THAT SEVERAL INCHES OF SNOW WILL BE POSSIBLE AND A WINTER
WEATHER ADVISORY MAY BE NEEDED.

A SIGNIFICANT DEGREE OF UNCERTAINTY EXISTS ON THE TRACK...TIMING AND
STRENGTH OF THIS SYSTEM AS IT DEVELOPS. STAY TUNED TO LATER
FORECASTS AND OUTLOOKS AS THEY REFINE THE POTENTIAL FOR ACCUMULATING
SNOW AND POSSIBLY ICE.
