May 8 Severe Weather Update #2

The severe weather threat across the state is coming to an end, as the current line of severe warned storms is just entering Illinois. Other showers and isolated thunderstorms will continue during the overnight for much of the state as precipitation wraps around the low pressure system. Thus far it appears that the lack of instability over the state hindered the threat of severe weather...

The first reports came in just after 5 PM with damaging wind reports in Marion and Poweshiek counties, both of which in the 60-65 mph range. Additional reports at ~6:30 PM from Sigourney, IA where a semi-trailer was blown off the road. And the latest report near Muscatine, IA where ~65 mph winds have occurred with the storms now entering Illinois. One other rogue report came in from an Iowa DNR officer to the east of Spencer, IA where a brief tornado spin-up was reported; likely more of a landspot that was able to pick up some dirt and/or field debris.

This should end our chances of thunderstorms and severe weather until next week as a system on Tuesday may bring a chance of significant severe weather across the Plains.
