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.

CAPABLE OF PRODUCING AS PWATS ARE 140 PERCENT OF NORMAL.  WILL
CONTINUE FLOOD WATCH THRU TUES MORN.

SHORT WAVE PASS OVER CENTRAL INDIANA EARLY ON THURS MORNING.  MODELS
DIFFER ON STRENGTH BUT BOTH POINT TO SIMILAR TIMING.  LAST SEVERAL
RUNS HAVE BEEN CONSISTENTLY POINTING TO THURS SO WILL MENTION MORE
SO IN NEXT PACKAGE.  THURS NITE/FRI DRYS OUT A BIT AND WILL REMAIN
WARM BUT NOT AS HUMID.
