SIGNIFICANT WEATHER OUTLOOK
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
449 AM CDT SUN JUN 9 2002

...ONE MORE DAY OF QUIET BUT WARM WEATHER...THEN THUNDERSTORMS AND
MORE RAIN ON THE WAY...

ONCE AGAIN VERY WARM MOIST AIR WAS BEING PUSHED NORTHWARD PRIMARILY
UP THE MISSOURI RIVER VALLEY INTO THE DAKOTAS AND MINNESOTA.  THIS IS
ALSO WHERE THE MAIN THUNDERSTORM ACTIVITY WAS ONCE AGAIN LOCATED.  AN
UPPER LEVEL WAVE...LOCATED OVER OKLAHOMA...WAS MOVING NORTHEAST AND
THERE IS A SLIGHT CHANCE IT COULD BRING A FEW SHOWERS AND
THUNDERSTORMS TO AREAS SOUTH OF HIGHWAY 34 AFTER MIDNIGHT TONIGHT.
CONFIDENCE IS NOT HIGH SO ONLY ABOUT A 20 PERCENT CHANCE OF THIS
HAPPENING.

A COLD FRONT IS NOW FORECAST TO APPROACH AND MOVE ACROSS THE MID
MISSISSIPPI RIVER VALLEY ON MONDAY AND TUESDAY.  ON MONDAY...THOUGH
THE SURFACE FRONT WILL STILL BE WEST OF OUR WARNING AND FORECAST
AREA...STRONG SOUTHERLY FLOW WILL PUMP OUR REGION FULL OF LOW LEVEL
MOISTURE. THIS COMBINED WITH AN APPROACHING UPPER LEVEL WAVE SHOULD
PROVIDE ENOUGH ATMOSPHERIC INSTABILITY TO TRIGGER THUNDERSTORMS.
THUNDERSTORMS ON MONDAY SHOULD BE OF AN ELEVATED NATURE...MEANING
MOST OF THUNDERSTORMS ARE NOT EXPECTED TO BE SEVERE...BUT A FEW
ISOLATED 3/4 INCH OR ONE INCH HAIL EVENTS WILL BE POSSIBLE.

OF A MORE SERIOUS NATURE IS THE POTENTIAL FOR MORE SIGNIFICANT
RAINFALL TO BE GENERATED BY THIS FRONTAL SYSTEM...ESPECIALLY ON
TUESDAY AND TUESDAY NIGHT. DUE TO THE RECENT HEAVY RAIN EVENT...AND
SEVERAL RIVERS STILL IN FLOOD...THIS WILL HAVE TO BE WATCHED
CAREFULLY.

SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY BUT MAY BE NECESSARY ON
MONDAY AFTERNOON.

EMERGENCY MANAGERS AND EMERGENCY RESPONDERS WHO HAVE RESPONSIBILITIES
ALONG AREA RIVERS THAT ARE IN FLOOD...OR HAVE RECENTLY BEEN IN
FLOOD...SHOULD MONITOR LATER FORECASTS AND STATEMENTS FOR UPDATED
INFORMATION CONCERNING THE POTENTIAL FOR POSSIBLE HEAVY RAIN ON
TUESDAY AND TUESDAY NIGHT.
