...POWERHOUSE STORM SYSTEM TO BRING POTENTIAL OF BRIEF WINTRY
PRECIPITATION LATE TONIGHT AND THURSDAY MORNING AND VERY STRONG
WINDS THURSDAY NIGHT...

A STRONG LOW PRESSURE SYSTEM WILL BEGIN TO AFFECT THE REGION
TONIGHT WITH RAIN AND THUNDERSTORMS OVERSPREADING NORTHERN
ILLINOIS AND NORTHWEST INDIANA AFTER MIDNIGHT. TEMPERATURES NEAR
THE GROUND AND ALOFT ARE BOTH FORECAST TO BE PRECARIOUSLY CLOSE TO
FREEZING. WHILE CURRENT INDICATIONS ARE THAT THE PRECIPITATION
SHOULD MOSTLY FALL AS JUST RAIN...A CHANGE IN TEMPERATURE AS
LITTLE AS A DEGREE OR TWO COLDER COULD RESULT IN PRECIPITATION
FALLING AS A PERIOD OF VERY HEAVY SNOW...SLEET...OR FREEZING
RAIN. WHILE THE POTENTIAL IS NOT HIGH THAT WINTRY PRECIPITATION
WILL OCCUR...THE AREA WITH THE GREATEST LIKELIHOOD OF THIS
HAPPENING IS NORTH OF INTERSTATE 80. THOSE PLANNING TRAVEL SHOULD
CLOSELY MONITOR LATER FORECASTS FOR TONIGHT AND THURSDAY MORNING.

BY LATE THURSDAY AFTERNOON...A STRONG COLD FRONT WILL RAPIDLY
SWEEP ACROSS THE AREA. THERE IS A CHANCE THAT AN INTENSE SQUALL
LINE COULD ACCOMPANY THE FRONT. WHILE LITTLE OR NO LIGHTNING MAY
ACCOMPANY THE SQUALL LINE...THERE IS A CHANCE THAT BRIEF HEAVY
RAIN AND DAMAGING WINDS COULD OCCUR...ESPECIALLY SOUTHEAST OF A
CHICAGO TO LA SALLE PERU LINE.

FINALLY...VERY STRONG WINDS ARE LIKELY THURSDAY NIGHT. SUSTAINED
WINDS ARE FORECAST TO INCREASE TO 25 TO 35 MPH WITH GUSTS OVER 50
MPH EXPECTED.
