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 GREEN BAY WI
345 PM CDT SAT JUL 20 2002

THE MOVEMENT OF THE WARM FRONT NOW OVER NORTHERN IOWA AND ILLINOIS WILL
BE THE TRICK TO BOTH THE TEMPERATURE AND PRECIPITATION FORECAST THE NEXT
DAY OR TWO. CONVECTION NOW OVER SOUTHWEST WISCONSIN AND CLOUDS OVER THE
REST OF THE STATE HAVE HELD UP IT/S NORTHWARD MOVEMENT. IT WILL LIKELY
BE THE FOCUS OF ADDITIONAL THUNDERSTORMS LATER TONIGHT...WHICH WILL ALSO
HINDER IT FROM MOVING NORTH. 18UTC ETA KEEPS IT SOUTH OF MOST OF THE
FORECAST AREA TOMORROW...WHICH WOULD BE THE DIFFERENCE BETWEEN 85 AND 95
DEGREES FOR HIGH TEMPERATURES. THINK IT WILL GET AT LEAST AS FAR NORTH
AS A GREEN BAY TO WAUSAU LINE SO WILL KEEP TEMPERATURES OF 90F AND
MENTION HEAT INDICES OF 95 TO 100 FOR SUNDAY AFTERNOON. SHOULD BE
THUNDERSTORMS ALONG THE APPROACHING WEAK COLD FRONT SUNDAY AFTERNOON AND
NIGHT WITH MODELS DIFFERENT AS FAR AS HOW FAST AND FAR SOUTH THE FRONT
GETS. AVN LOOKS TOO STRONG WITH SURFACE LOW MONDAY.

.GRB...NONE.
