HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
101 PM 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...THIS AFTERNOON AND TONIGHT...

SCATTERED STRONG THUNDERSTORMS WILL BE POSSIBLE THIS AFTERNOON 
ACROSS PORTIONS OF EASTERN IOWA AND NORTHWEST ILLINOIS. HOT AND 
HUMID AIR WILL COMBINE WITH A WEAK BOUNDARY LEFT OVER FROM THIS 
MORNINGS SHOWERS AND THUNDERSTORMS...TO PROVIDE THE FOCUS FOR WIDELY 
SCATTERED AFTERNOON THUNDERSTORMS. DUE TO THE HIGH INSTABILITY IN 
THE ATMOSPHERE...STRONG DOWNBURST WINDS WILL BE POSSIBLE FROM THESE 
THUNDERSTORMS...ALONG WITH LOCALLY HEAVY RAIN.

TONIGHT...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.
