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

A STALLED BOUNDARY...ROUGHLY NEAR AND ALONG THE I-80 CORRIDOR WILL
PROVIDE THE FOCUS FOR THUNDERSTORMS TO REFIRE LATER TODAY.  UNSTABLE
AIR ALONG AND SOUTH OF THE BOUNDARY COMBINED WITH DRY AIR ALOFT WILL
RESULT IN SOME OF THE STORMS REACHING SEVERE LEVELS.  THE PRIMARY
THREAT WILL BE LARGE HAIL UP TO AND IN EXCESS OF THE SIZE OF GOLF-
BALLS AND DAMAGING WINDS OF 60 MPH OR MORE WITH ISOLATED VERY
DAMAGING WINDS NEAR 80 MPH POSSIBLE.   A FEW TORNADOES MAY ALSO BE
POSSIBLE THOUGH LOW LEVEL WIND FIELDS ARE NOT AS SUPPORTIVE OF
TORNADOES AS LAST EVENINGS EVENT OVER THE AREA.  THE STORMS WILL
MOVE SOUTHEAST OF THE AREA BY MID TO LATE EVENING.  BRIEF...LOCALLY
HEAVY RAINS MAY ALSO ACCOMPANY SOME OF THE STORMS.

CURRENTLY...LOCATIONS SOUTHEAST OF A FREEPORT ILLINOIS TO OTTUMWA
IOWA LINE ARE AT MOST RISK OF SEVERE THUNDERSTORMS.

THE STORM PREDICTION CENTER HAS THE SOUTHEAST 1/2 OF THE OUTLOOK
AREA IN A SLIGHT RISK.

EMERGENCY MANAGERS ARE URGED TO LISTEN TO LATER FORECASTS AS THE
RESPECTIVE THREATS BECOME BETTER DEFINED.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

SATURDAY NIGHT AND SUNDAY...A SLOW MOVING STORM SYSTEM WILL PRODUCE
MORE ROUNDS OF SHOWERS AND THUNDERSTORMS.   LOCATIONS SOUTH OF I-80
MAY EXPERIENCE SOME SEVERE STORMS WITH THE GREATEST THREAT LARGE HAIL
AND POSSIBLY SOME STRONG WINDS.  THE SLOW MOVEMENT OF THE SYSTEM WILL
ALLOW FOR LOCALLY HEAVY RAINFALL...THIS MAY RESULT IN LOCALIZED
MINOR FLOODING IN LOW LYING AND FLOOD PRONE LOCATIONS AND PUSH SOME
RIVER LEVELS TO REACH OR EXCEED FLOOD LEVELS.

WEDNESDAY AND THURSDAY...ANOTHER STORM SYSTEM WILL AFFECT THE REGION
RESULTING IN A CHANCE FOR MORE THUNDERSTORMS.  IT IS TOO EARLY TO
ASSESS ANY SEVERE RISK OR HEAVY RAINFALL POTENTIAL WITH THIS SYSTEM.
