HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
144 PM CDT TUE JUL 8 2003


...POTENTIALLY DANGEROUS WEATHER SCENARIO DEVELOPING FOR WEDNESDAY...

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

.DAY ONE...EVENING AND OVERNIGHT...
THERE WILL BE A RISK OF SEVERE THUNDERSTORMS INTO THIS EVENING
MAINLY...ALONG AND SOUTH OF INTERSTATE 80. DAMAGING WINDS AND LARGE
HAIL WILL BE THE MAIN CONCERN ALONG AND SOUTH OF A LINE FROM
FAIRFIELD THROUGH WASHINGTON AND MUSCATINE TO NEAR PRINCETON
ILLINOIS. THERE IS ALSO A THREAT OF A FEW TORNADOES ALONG THE IOWA
MISSOURI BORDER...EAST INTO WEST CENTRAL ILLINOIS.  NORTH OF THIS
AREA...THE MAIN THREAT WILL BE LARGE HAIL. THERE WILL ALSO BE A
POTENTIAL FOR LOCALLY HEAVY RAINS THROUGH EARLY EVENING. THE HEAVY
RAIN WILL CREATE A POTENTIAL FOR FLOODING OF SMALL STREAMS AND RIVERS
ALONG WITH STREET FLOODING IN URBAN AREAS. THIS ROUND OF
THUNDERSTORMS WILL MOVE EAST OF THE AREA BY EARLY THIS EVENING.

ANOTHER ROUND OF STORMS WILL BE POSSIBLE LATE TONIGHT.  THESE
STORMS SHOULD BE FOCUSED ON AREAS NORTH OF INTERSTATE 80 AND WILL
HAVE THE POTENTIAL FOR PRODUCING LARGE HAIL AND LOCALLY HEAVY RAINS.
AREAS SOUTH OF INTERSTATE 80 COULD SEE SOME SCATTERED THUNDERSTORMS
DURING THE OVERNIGHT HOURS...BUT THESE ARE NOT EXPECTED TO BE SEVERE.

THE THUNDERSTORMS THIS AFTERNOON THROUGH TONIGHT WILL BE DEVELOPING
ALONG AND NORTH OF A STATIONARY FRONT OVER SOUTHERN IOWA AND
NORTHERN ILLINOIS.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH TUESDAY...
A DANGEROUS SITUATION IS SETTING UP FOR WEDNESDAY AFTERNOON AND
EVENING OVER THE MID MISSISSIPPI VALLEY.  SEVERE THUNDERSTORMS ARE
EXPECTED TO MOVE INTO EASTERN IOWA AND NORTHWEST ILLINOIS LATE
WEDNESDAY AFTERNOON OR EARLY IN THE EVENING. A FEW TORNADOES ALONG
WITH LARGE HAIL AND DAMAGING STRAIGHT LINE WINDS WILL BE POSSIBLE
WITH THESE STORMS.  AT THIS TIME THE TORNADIC THREAT APPEARS TO BE
THE GREATEST ALONG AND NORTH OF HIGHWAY 34.

A LOW PRESSURE SYSTEM DEVELOPING THIS EVENING OVER THE CENTRAL
PLAINS WILL MOVE EAST ALONG THE FRONT...CURRENTLY IN PLACE OVER
SOUTHERN IOWA AND NORTHERN ILLINOIS.  THERE IS SOME UNCERTAINTY ON
THE TRACK OF THE LOW...BUT CURRENT INDICATIONS ARE THAT IT WILL
MOVE ACROSS THE NORTHERN HALF OF IOWA OR SOUTHERN MINNESOTA
DURING THE LATE AFTERNOON OR EARLY EVENING HOURS. SEVERE
THUNDERSTORMS DEVELOPING AHEAD OF AND JUST SOUTH OF THE LOW
PRESSURE SYSTEM WILL HAVE THE BEST POTENTIAL TO BECOME TORNADIC.

THE FLOODING THREAT WILL ALSO PERSIST THROUGH THE DAY WEDNESDAY...
SINCE ANY STORMS THAT DEVELOP WILL HAVE THE POTENTIAL OF PRODUCING
LOCALLY HEAVY RAINFALL.

THE ACTIVE WEATHER WILL END WEDNESDAY NIGHT...AS A COOLER AND DRIER
AIRMASS SETTLES IN OVER THE REGION.  THE NEXT THUNDERSTORM THREAT
WILL BE EARLY NEXT WEEK.


.SPOTTER INFORMATION STATEMENT...

AND POSSIBLY AGAIN LATE TONIGHT.  SPOTTERS...EMERGENCY MANAGERS AND
LAW ENFORCEMENT OFFICIALS AND THE MEDIA SHOULD MONITOR WEDNESDAY
SEVERE WEATHER POTENTIAL CLOSELY.  AS MORE INFORMATION BECOMES
AVAILABLE...THE EXTENT OF THE THREAT...ITS TIMING AND LOCATION WILL
BE MORE APPARENT.
