The severe weather threat on Monday materialized as forecast with a cluster of strong storms developing mid afternoon over central Iowa and then congealed into a damaging line of storms that plowed east. At the time of this feature writing, this system has yet to be a labelled a derecho, but it seems likely that it met the criteria of duration and areal coverage. The featured map presents NWS Local Storm Reports of thunderstorm wind gust and damage. As with many storms this year, this system appeared to produce a number of brief tornadoes as well making the event even more dangerous. NWS offices will be out surveying the damage today and the IEM has a Google Group you can subscribe to for email alerts when they issue damage survey reports.
