HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
532 AM CDT THU JUL 3 2003

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

.DAY ONE...TODAY AND TONIGHT...

SCATTERED SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE AREA THIS 
MORNING AS PART OF A DECAYING NOCTURNAL THUNDERSTORM COMPLEX.  THESE 
THUNDERSTORMS ARE NOT EXPECTED TO CAUSE SEVERE WEATHER...THOUGH MAY 
CAUSE A BRIEF HEAVY DOWNPOUR AND GUSTY WINDS AS THEY MOVE THROUGH.

THIS AFTERNOON AND EVENING MORE THUNDERSTORMS ARE EXPECTED TO 
DEVELOP ALONG A WEAK SURFACE FRONT THAT WILL BE DRAPED ACROSS 
NORTHERN IOWA AND SOUTHERN WISCONSIN. THESE THUNDERSTORMS WILL THEN 
MOVE INTO THE FORECAST AREA...AND THERE IS A SLIGHT RISK OF SEVERE 
WEATHER WITH THESE STORMS...MAINLY ALONG AND NORTH OF INTERSTATE 
80.  THE MAIN THREAT WITH THESE STORMS IS LARGE HAIL...AS THE 
ATMOSPHERE WILL BE VERY UNSTABLE ALLOWING FOR VERY STRONG UPDRAFTS.  
A SECONDARY THREAT WILL BE FOR DAMAGING WINDS...BUT SHOULD ONLY 
OCCUR UP UNTIL AN HOUR OR TWO AFTER SUNSET.  LATER TONIGHT...THE 
THREAT SHIFTS TO HEAVY RAIN...AND POSSIBLE LOCALIZED FLOODING.  AT 
THIS TIME...THE GROUND IS RELATIVELY DRY...AND MOST AREAS WILL BE 
ABLE TO ACCEPT SIGNIFICANT RAINFALL WITHOUT CAUSING FLOODING.  URBAN 
AREAS...AS ALWAYS...WILL BE AT RISK OF LOCALIZED FLOODING WITH VERY 
HEAVY RAINS.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...

ANOTHER ACTIVE WEATHER DAY IS EXPECTED FOR FRIDAY AND FRIDAY 
NIGHT...AS THE ACTUAL SURFACE FRONT FINALLY MOVES ACROSS THE 
FORECAST AREA.  PLENTY OF INSTABILITY AND MOISTURE WILL BE AVAILABLE 
ALONG AND SOUTH OF THE FRONT AS IT MOVES SOUTH...AND THUNDERSTORMS 
ARE EXPECTED TO INITIATE BY EARLY AFTERNOON...AND CONTINUE THROUGH 
THE EVENING HOURS.  DURING THE AFTERNOON AND EARLY IN THE EVENING... 
THUNDERSTORMS WILL BE CAPABLE OF PRODUCING LARGE HAIL AND DAMAGING 
WINDS...AND EVEN A FEW TORNADOS WITH THE STRONGEST OF STORMS.  THIS 
WILL GRADUALLY TRANSITION TO A HIGH WIND AND LARGE HAIL THREAT BY 
LATE EVENING...AND AND OVERNIGHT HEAVY RAIN EVENT.   BY SATURDAY 
MORNING...THERE SHOULD ONLY BE SOME LINGERING THUNDERSTORMS ACROSS 
THE FAR SOUTH...WHICH WILL QUICKLY MOVE SOUTHEAST OUT OF THE AREA.  

SUNDAY NIGHT AND MONDAY ANOTHER COLD FRONT WILL MOVE ACROSS THE 
AREA...POSSIBLY BRINGING ANOTHER ROUND OF SEVERE WEATHER TO THE 
AREA...THOUGH IT IS TOO SOON TO DISCERN ANY DETAILS.  THIS FRONT 
WILL STALL ACROSS NORTHERN MISSOURI FOR TUESDAY AND WEDNESDAY... 
BRINGING CHANCES FOR THUNDERSTORMS TO AREAS ALONG AND SOUTH OF 
HIGHWAY 34 BOTH DAYS.  

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON AND TONIGHT...MAINLY 
ALONG AND NORTH OF INTERSTATE 80.  FRIDAY AND FRIDAY NIGHT SPOTTER 
ACTIVATION MAY ALSO BE NEEDED ACROSS THE AREA.  

STAY TUNED TO NOAA WEATHER RADIO AND OTHER LOCAL MEDIA FOR FURTHER
DETAILS OR UPDATES.
