...WINTRY MIX INCLUDING LIGHT SNOW ACCUMULATION TONIGHT...
TEMPERATURES WILL GRADUALLY FALL THIS AFTERNOON AND EVENING BEHIND
A COLD FRONT AND LIKELY DROP BELOW FREEZING FROM WEST TO EAST
THIS EVENING INTO EARLY OVERNIGHT. AS A STORM SYSTEM ORGANIZES TO
THE SOUTHEAST OF THE AREA TONIGHT...PRECIPITATION IS EXPECTED TO
EXPAND RAPIDLY NORTHWARD ACROSS THE AREA BETWEEN 7 AND 11 PM AND
PERSIST THROUGH MUCH OF THE NIGHT.
PRECIPITATION OVER THE NORTHERN CHICAGO SUBURBS AND WEST AND
SOUTHWEST ACROSS NORTH CENTRAL ILLINOIS...INCLUDING ROCKFORD AND
DIXON...WILL LIKELY BEGIN AS SNOW OR SLEET BEFORE CHANGING TO ALL
SNOW. FARTHER SOUTH FROM CHICAGO SOUTHWEST ALONG THE INTERSTATE 55
CORRIDOR TOWARD PONTIAC...RAIN TRANSITIONING TO SLEET IN THE
EVENING AND THEN EVENTUALLY TO ALL SNOW DURING THE OVERNIGHT IS
EXPECTED. A TEMPORARY PERIOD OF FREEZING RAIN IS EVEN POSSIBLE
DEPENDING ON HOW QUICKLY TEMPERATURES FALL.
THE POTENTIAL EXISTS FOR SNOW AND SLEET TO BRIEFLY FALL HEAVILY
AT TIMES...AND WHEN COMBINED WITH TEMPERATURES DROPPING BELOW
FREEZING COULD RESULT IN TRAVEL BECOMING HAZARDOUS. MOST AREAS
FROM CHICAGO WEST ACROSS NORTH CENTRAL ILLINOIS WILL EXPERIENCE
SNOWFALL AMOUNTS OF 2 INCHES OR LESS. A LOCALIZED BAND OR TWO OF
HEAVIER SNOWFALL TOTALS OF SEVERAL INCHES COULD FALL.
A CHANCE FOR LIGHT PRECIPITATION WILL LINGER INTO EARLY SUNDAY
MORNING...WHICH INCLUDES A CHANCE FOR FREEZING DRIZZLE...WHICH
COULD CONTINUE ANY POOR ROAD CONDITIONS THAT DEVELOP.
PERSONS PLANNING TRAVEL TONIGHT OR EARLY SUNDAY MORNING SHOULD
MONITOR LATER FORECASTS ON THIS WINTRY PRECIPITATION EVENT AND BE
PREPARED FOR ENCOUNTERING SLICK ROADS AS TONIGHT PROGRESSES.
