SIGNIFICANT WEATHER OUTLOOK
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
448 AM CDT SAT AUG 3 2002

WARMER AIR WILL MAKE A RETURN TO THE MIDWEST TODAY AND DEW POINTS
WILL BE ON THE RISE AS WELL.

EVERYTHING IS STILL POINTING TOWARD A SIGNIFICANT RAINFALL EVENT...
PROBABLY SOME SEVERE THUNDERSTORMS AS WELL...ACROSS THE UPPER
MISSISSIPPI RIVER VALLEY TONIGHT INTO SUNDAY.  THE LOW LEVEL FLOW HAS
ALREADY STRENGTHENED ACROSS THE CENTRAL PLAINS.  THIS WAS ACTING AS
THE CONVEYER BELT THAT WILL BRING HIGHER DEW POINT AIR INTO THE
MISSISSIPPI RIVER VALLEY.  AT THIS TIME IT APPEARS THAT THE BEST
SURFACE CONVERGENCE...IN THE FORM OF A FRONTAL BOUNDARY...COMBINED
WITH AN UPPER LEVEL DIVERGENT FLOW...TONIGHT AND SUNDAY MORNING...
WILL BE ALONG AND NORTH OF HIGHWAY 20.  THIS BOUNDARY WILL SAG SOUTH
INTO THE CENTRAL PART OF OUR WARNING AND FORECAST AREA ON SUNDAY...
ROUGHLY ALONG INTERSTATE 80...CONTINUING THE THREAT OF THUNDERSTORMS.
NORTH OF HIGHWAY 20...THERE COULD BE SOME 24 HOUR RAINFALL TOTALS OF
2 TO 4 INCHES.

SPOTTER ACTIVATION MAY BE NECESSARY TONIGHT...ESPECIALLY ALONG AND
NORTH OF HIGHWAY 20.  THE WIND PROFILE SUGGESTS ENOUGH SHEAR WILL BE
PRESENT TO SUPPORT SUPERCELL DEVELOPMENT WITH POTENTIAL FOR LARGE
HAIL.  AGAIN...THIS THREAT WILL BE PRIMARILY NORTH OF HIGHWAY 20...
EXTENDING INTO MINNESOTA AND WISCONSIN.
