Episode Narrative A cold front moved into Iowa during the evening of the 19th. The severe weather potential was fairly weak given the parameters. CAPE was only around 1000 to 1500 J/kg and precipitable water values were around an inch. The airmass was relatively dry with plenty of dry air in the low levels.

The storms moved into the far western part of the Des Moines CWA and produced winds of 60 to 70 MPH. Reports of tree and power line damage occurred with some outbuilding damage in Crawford, Carroll, and Sac Counties.
