A strong MCS moved southeast out of South Dakota into Iowa during the morning of the 13th.  The system was elevated in nature and swept southeast along the edge of the unstable airmass to the southwest.  Wind shear was fairly strong, 50 to 60 kts, helping to maintain the system.  Downdraft CAPE was over 1000 J/kg ahead of the storms, but being elevated the storms were only able to make partial use of the high CAPE.  As the storms rolled southeast across the state, they produced heavy rain and gusty winds.  A few gusts to around 60 MPH were recorded, but they were spotty.  Hail from the storms was under an inch in diameter.  The storms produced upwards of 2 inches of rain in a short period of time in some places as well.  The more significant part of this event was the formation of a strong wake low.  Strong winds developed in the wake of the storms with sustained winds around 40 MPH, and gusts of 60 to nearly 70 MPH reported across 7 counties of central Iowa.  The winds downed trees and power lines and also caused damage to some outbuildings.  A three foot diameter tree was blown down on an house in Nevada in Story County.  The strongest measured wind speed was received from a mesonet site in Colo with a 68 MPH wind gust.  Tree damage was widespread over southern Story County from Slater to Nevada.  As the storms moved through Guthrie County, lightning struck a house in Panora.  It blew a whole through the roof and started the insulation on fire, resulting in minor damage.  Lightning also struck a tree next to a house in Stuart.  The tree was damaged with pieces of the tree falling onto and damaging a car.
