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
TODAY CLOUDS AND PRECIPITATION ONGOING EARLY THIS MORNING ARE LIKELY
TO LIMIT THE SEVERE POTENTIAL BY LIMITING HEATING AND
DESTABILIZATION OF THE ATMOSPHERE. LATER TODAY SOME SUNSHINE IS
EXPECTED TO BREAK THROUGH THE CLOUDS...AND WARM SURFACE
TEMPERATURES. THIS WARMING WILL INCREASE OUR INSTABILITY AND COMBINED
WITH PLENTIFUL MOISTURE THERE WILL BE SCATTERED STRONG TO SEVERE
STORMS. THE STORM PREDICTION CENTER HAS PLACED ALL OF THE OUTLOOK
AREA IN A SLIGHT RISK FOR SEVERE THUNDERSTORMS. THIS INCLUDES A
RISK FOR TORNADOES...LARGE HAIL...AND DAMAGING WIND GUSTS.

THESE STORMS ARE MOVING OVER AREAS THAT HAVE ALREADY RECEIVED
SIGNIFICANT AMOUNTS OF RAIN OVER THE LAST WEEK.  LOCALLY HEAVY RAINS
IN THESE AREAS COULD PRODUCE FLASH FLOODING. IN PORTIONS OF
SOUTHEAST AND EAST CENTRAL IOWA AND NORTHEAST MISSOURI THERE IS A
FLASH FLOOD WATCH FOR THIS MORNING.

MINOR FLOODING IS EXPECTED ON A FEW IOWA TRIBUTARY RIVERS DUE TO
THIS RECENT RAINFALL. FURTHER INFORMATION CAN BE FOUND IN THE LATEST
FLOOD STATEMENT.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THERE IS A NEAR DAILY CHANCE OF THUNDERSTORMS FROM SUNDAY THROUGH
TUESDAY...AND AGAIN ON THURSDAY.

AT THIS TIME...THERE IS NO CLEAR INDICATION REGARDING THE RISK OF
SEVERE STORMS BEYOND SATURDAY.

THERE IS THE POSSIBILITY OF LOCALLY HEAVY RAINFALL DURING THE PERIOD
WHICH MAY RESULT IN SOME LOCALIZED FLOODING.  THIS EXTENDED PERIOD
OF ACTIVE WET WEATHER MAY ALSO RESULT IN FURTHER RISES ON AREA RIVERS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED LATE THIS AFTERNOON AND EVENING.
