NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in.
Did it verify
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.

MODELS NOT INDICATING ANYTHING TOO DIFFERENT THAN WHAT THE CURRENT FORECAST IS ADVERTISING ATTM...SO NO MAJOR CHANGES ARE LIKELY WITH THIS PACKAGE. THE PERSIS- TENT (AND DEEP) E/SE FLOW SHOULD KEEP BRINGING WEAK S/WS TO THE CWFA AS THE UNSTABLE AIRMASS CONTINUES TO MOISTEN UP (PEAKING AOA 2.2 BY TUES). BY MID WEEK...THE STRONG UPPER RIDGE OVER THE WRN STATES WILL BE IN PLACE JUST AS A COOL FRONT APPROACHES FROM THE NORTH. ITS NOT LIKELY THE FRONT WILL MAKE IT TO THE COAST BUT THE PRE-FRONTAL ENVI- RONMENT IS PROGGED TO BE ON THE HOT/DRY/CAPPED SIDE. SFC AND MID LVL WINDS FROM THE SW SHOULD PUT A KIBOSH ON ANY WIDESPREAD PCPN FOR THE LATTER HALF OF THE WEEK. HOWEVER THE LONG-RANGE GUIDANCE NUMBERS ARE STILL NOT REFLECTING THIS THINKING.
