An early spring storm lifted northeast out of the southwest U.S.  The surface low pressure moved northeast into Iowa during the afternoon and pushed northeast out of the state during the evening.  The dry punch moved into southern Iowa during the afternoon and the airmass became unstable.  Lifted indices fell to the -1 to -4 C. range with CAPE values in the 400 to 1000 J/kg range.  The LCL was fairly low during the afternoon, in the 600 to 800 meter range.  With the upper low pressure area also lifting northeast into Iowa, the freezing level was quite low at 9700 feet AGL.  Thunderstorms formed in an arc across Iowa at the nose of the dry punch.  The storms lifted north into the central sections of the state by late afternoon.  Many of the storms produced hail, some of which was severe.  Reports of large hail were absent however.  There were several reports of brief tornado touchdowns.  None of them remained on the ground for more than a couple of minutes.  Two brief touchdowns occurred in Davis County early on in the event.  During the late afternoon, as the line of storms approached central Iowa, several brief touchdowns occurred.  These reports were to the south of Des Moines in Warren County, and to the east of Des Moines in southeast Polk County.  Damage report were limited as the touchdowns were so brief.  As the storms moved across Warren County, high winds blew a car off the road near Carlisle.  No injuries were reported.
