SIGNIFICANT WEATHER OUTLOOK
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
542 AM CDT THU MAY 9 2002

...WINDY TODAY AND POTENTIAL FOR HEAVY RAIN SATURDAY...

ISOLATED SPRINKLES WILL END BY MID MORNING AS A STORM SYSTEM MOVES INTO
THE NORTHERN GREAT LAKES. STRONG WINDS OF 20 TO 30 MPH WITH GUSTS TO 40
MPH CAN BE EXPECTED DURING THE DAY...AND THEN DIMINISH OVERNIGHT AS
HIGH PRESSURE BUILDS INTO THE REGION.

A STORM SYSTEM WILL DEVELOP IN THE CENTRAL PLAINS AND AFFECT THE REGION
ON SATURDAY. A STRONG LOW LEVEL JET IS FORECAST TO PULL MOISTURE NORTH
FROM THE GULF OF MEXICO...AND COLLIDE WITH A WARM FRONT OVER NORTHERN
MISSOURI AND CENTRAL ILLINOIS.

THE ISENTROPIC LIFT PROVIDED BY THE WARM FRONT WILL SATURATE THE
ATMOSPHERE CAUSING WIDESPREAD RAIN TO DEVELOP.  THE PROXIMITY OF THE
FRONT...GULF MOISTURE...AND APPROACHING LOW WILL PROVIDE THE FOCUS FOR
THE DEVELOPMENT HEAVY RAIN. AS THE WARM FRONT MOVES INTO THE AREA
SATURDAY EVENING...THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG AND SOUTH
OF THE FRONT INCREASING THE POTENTIAL FOR HEAVY RAIN. CURRENT
INFORMATION INDICATES THE WARM FRONT SHOULD MOVE NO FURTHER NORTH THAN
THE INTERSTATE 80 CORRIDOR.

AT THIS TIME...IT APPEARS THAT GENERAL RAINFALL OF 1 TO 1.5 INCHES
SHOULD OCCUR DURING THE DAYLIGHT AND EVENING HOURS...WITH LOCAL AMOUNTS
OF 2 INCHES POSSIBLE. SUFFICIENT SHEAR IS ALSO FORECAST TO BE PRESENT...
THUS THERE WILL ALSO BE THE POTENTIAL FOR SEVERE WEATHER.

EMERGENCY MANAGERS ARE URGED TO LISTEN TO LATER FORECASTS AS THE
RAINFALL AND SEVERE WEATHER THREAT FOR SATURDAY BECOME BETTER DEFINED.
