Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
800 PM EDT TUE JUN 8 2004

.UPDATED...
DOING A QUICK UPDATE TO BRING THE SHOWERS AND THUNDERSTORMS FARTHER
SOUTH FASTER TONIGHT. WHILE THE CONVECTION BETWEEN MKG AND GRB HAS
WEAKENED AS IT MOVED OVER LAKE MICHIGAN THIS EVENING...MORE
CONVECTION HAS DEVELOPED NEAR TVC SOUTHWEST TO NEAR MTW WI.
MEANWHILE THE SHORTWAVE MOVE MO CONTINUES TO MOVE NE TOWARD SW LOWER
MICHIGAN.  THIS HAS HELPED THUNDERSTORMS FORM BETWEEN CHI AND MKE.
THE RUC SHOWS THIS AREA BECOMING MORE EXTENSIVE OVER CNTL LOWER MI
BEFORE MIDNIGHT. WHILE THE SHEAR PROFILE DOES NOT SUPPORT SEVERE
WEATHER... IT SURE LOOKS LIKE SHOWERS AND THUNDERSTORM WILL BE
GENEROUSLY SCATTERED AROUND BY 10 PM NORTH OF GRR. GIVEN PWAT VALUES
OVER 1 1/2 INCHES...ANY OF THESE COULD PRODUCE VERY HEAVY RAIN.
HOWEVER WITH THEM MOVING NE AROUND 30 MPH...FLOODING SHOULD NOT BE A
BIG ISSUE EITHER.
