Special Weather Statement 14:44:51.5256008

...POTENTIAL FOR A WINTRY MIX TUESDAY THROUGH WEDNESDAY MORNING...

RAIN IS EXPECTED ACROSS CENTRAL ILLINOIS TONIGHT AS A LOW PRESSURE
SYSTEM ORGANIZES IN THE SOUTHERN PLAINS. AS THE RAIN BEGINS TO
EXPAND NORTH OVERNIGHT AND THROUGH TUESDAY MORNING. A WINTRY
COMBINATION OF SNOW AND SLEET...WITH ONLY MINOR ACCUMULATIONS
UNDER ONE HALF INCH ARE EXPECTED. IN ADDITION...LIGHT FREEZING
RAIN IS POSSIBLE. IF THE FREEZING RAIN MATERIALIZES...IT WOULD BE
MOST FAVORED IN THE MORNING HOURS FROM PONTIAC TO RENSSELAER AND
NORTH TO THE INTERSTATE 80 CORRIDOR. TO THE NORTH OF THIS
AREA...LIGHT SNOW AND SLEET IS MORE FAVORED IF A MIX OCCURS.

ANY SNOW...SLEET...OR FREEZING RAIN ON TUESDAY LOOKS TO BE
LIGHT...WHILE RAIN WILL BE MORE STEADY AT TIMES AND IS FAVORED TO
BE THE PRIMARY PRECIPITATION TYPE IN MOST AREAS. ANOTHER FACTOR
IS THAT THE MILD TEMPERATURES WHICH OCCURRED ON MONDAY MAY PREVENT
LIGHT RAIN FROM FREEZING ON SOME SURFACES IN THE MORNING DESPITE
THE TEMPERATURES AT THAT TIME BEING AT FREEZING. EVEN A SLIGHT
AMOUNT OF GLAZE HOWEVER CAN CAUSE TRAVEL IMPACTS...SO PREPARE FOR
POTENTIALLY LONGER TRAVEL TIMES ON TUESDAY.

AS THE LOW PRESSURE MOVES NORTHEAST TUESDAY NIGHT AND TO INDIANA
BY WEDNESDAY MORNING...COLDER AIR WILL WRAP BACK INTO THE REGION.
THIS IS LIKELY TO TRANSITION THE RAIN TO SNOW IN SOME AREAS
TUESDAY NIGHT INTO WEDNESDAY. MINOR ACCUMULATIONS...UNDER ONE
INCH...ARE POSSIBLE DURING THAT TIME.

CONTINUE TO MONITOR THE FORECAST...OUTLOOKS...AND ADDITIONAL
STATEMENTS THROUGH WEDNESDAY MORNING FOR MORE INFORMATION.
