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.

A FLASH FLOOD WATCH IS IN EFFECT UNTIL 7 PM FRIDAY FOR AREAS
NORTH OF A LINE FROM OSKALOOSA IOWA...TO CLINTON...AND TO
MILLEDGEVILLE ILLINOIS. THE FLASH FLOOD WATCH EXPANDS TONIGHT TO
INCLUDE KEOKUK...WASHINGTON...LOUISA...MUSCATINE...SCOTT...ROCK
ISLAND...AND WHITESIDE COUNTIES UNTIL 7 PM FRIDAY.

.DAY ONE...TODAY AND TONIGHT

THE STORM PREDICTION CENTER HAS A SLIGHT RISK OF SEVERE
THUNDERSTORMS ACROSS THE ENTIRE AREA. THE PRIMARY THREATS ARE HAIL
AND DAMAGING WINDS.

SCATTERED THUNDERSTORMS WILL BECOME MORE NUMEROUS THIS AFTERNOON AND
TONIGHT AS A LARGE THUNDERSTORM COMPLEX DEVELOPS. HIGH MOISTURE
LEVELS IN THE LOWER ATMOSPHERE COMBINED WITH A STATIONARY FRONT WILL
ALLOW STORMS TO DEVELOP AND MOVE OVER THE SAME AREAS.

THE AREA MOST AT RISK FOR HEAVY RAIN IS ALONG AND NORTH OF A LINE
FROM OTTUMWA IOWA TO STERLING ILLINOIS. THE PROBABILITY IS HIGH THAT
HEAVY RAIN WILL BE SEEN WITH POTENTIAL RAINFALL RATES OF UP TO 2
INCHES PER HOUR.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

THE STORM PREDICTION CENTER HAS A SLIGHT RISK OF SEVERE
THUNDERSTORMS ACROSS THE ENTIRE AREA FRIDAY. THE PRIMARY THREATS ARE
HAIL AND DAMAGING WINDS.

THE THUNDERSTORM COMPLEX THAT DEVELOPS THURSDAY NIGHT WILL SLOWLY
MOVE ACROSS THE AREA ON FRIDAY. HEAVY RAIN AND POTENTIAL FLASH
FLOODING ARE POSSIBLE NORTH OF AN OTTUMWA TO STERLING LINE. YET
ANOTHER THUNDERSTORM COMPLEX WILL DEVELOP FRIDAY NIGHT ACROSS EASTERN
KANSAS AND WESTERN MISSOURI. CURRENT INFORMATION SUGGESTS THAT THIS
THUNDERSTORM COMPLEX WILL AFFECT AREAS SOUTH OF INTERSTATE 80.

A POTENTIALLY DANGEROUS SITUATION IS SETTING UP STARTING THIS
WEEKEND AND CONTINUING INTO NEXT WEEK REGARDING AREA RIVERS. AS EACH
ADDITIONAL ROUND OF HEAVY RAIN MOVES ACROSS IOWA...MORE OF THE
RAINFALL WILL RUN OFF INTO AREA RIVERS AND PUSH RIVER LEVELS
HIGHER.

FLOODING OF VARYING MAGNITUDES IS LIKELY ON ALL OR PARTS OF THE
WAPSIPINICON...CEDAR...PECATONICA...ROCK...AND IOWA RIVERS.
SIGNIFICANT RISES ARE EXPECTED ON THE MISSISSIPPI RIVER WITH MINOR
FLOODING POSSIBLE FROM THE QUAD CITIES ON SOUTH.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON AND TONIGHT. SPOTTERS
AND EMERGENCY MANAGERS ARE ENCOURAGED TO REPORT HEAVY RAINFALL
AMOUNTS AND FLOODING OVER THE NEXT SEVERAL DAYS.
