THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTH CENTRAL
ILLINOIS...NORTHWEST ILLINOIS...WEST CENTRAL ILLINOIS...EAST
CENTRAL IOWA...NORTHEAST IOWA...SOUTHEAST IOWA AND NORTHEAST
MISSOURI.

.DAY ONE...TODAY AND TONIGHT

THE STORM PREDICTION CENTER HAS A SLIGHT RISK FOR SEVERE STORMS IN
THE OUTLOOK TODAY FOR AREAS SOUTH OF A LINE FROM MARENGO...THROUGH
CEDAR RAPIDS IN IOWA...TO FREEPORT ILLINOIS. THUNDERSTORMS ARE
EXPECTED TO DEVELOP IN THE AFTERNOON AND CONTINUE INTO THE EVENING
AHEAD OF A STRONG COLD FRONT. THE MAIN SEVERE WEATHER THREATS WILL
BE LARGE HAIL AND DAMAGING WIND. THE POTENTIAL FOR SEVERE STORMS
WILL BE SOMEWHAT DEPENDENT ON THE EXTENT OF CLOUD COVER THAT MAY
LIMIT AFTERNOON HEATING AND INSTABILITY.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

WINDY CONDITIONS WILL DEVELOP FRIDAY MORNING AND CONTINUE THROUGH THE
AFTERNOON HOURS. WEST TO NORTHWEST WINDS WILL BE SUSTAINED FROM 20
TO 30 MPH...WITH GUSTS UP TO 45 MPH.

EXPECT COLD CONDITIONS FRIDAY NIGHT...WITH LOWS IN THE MID TO UPPER
30S. PASSING CLOUD COVER AND WINDS MAINTAINING AT 10 TO 20 MPH
OVERNIGHT WILL BE ENOUGH TO PREVENT WIDESPREAD FROST FROM FORMING.
COLD CONDITIONS ARE THEN EXPECTED AGAIN SATURDAY NIGHT. LIGHT WINDS
WOULD FAVOR FROST...BUT THERE IS STILL SOME UNCERTAINTY ABOUT CLOUD
COVER AND DURATION OF LIGHT WINDS TO ALLOW FOR FROST FORMATION. STAY
TUNED FOR FURTHER UPDATES AND FORECASTS CONCERNING THIS FROST
POTENTIAL FOR THE UPCOMING WEEKEND.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON INTO THE EARLY
EVENING HOURS.
