Overview

A low pressure system moved from the Central Plains to across northeast Iowa during late afternoon on Monday, May 27th (Memorial Day). The storm system brought clouds and widespread rain (moderate to heavy at times) to much of southeast Minnesota and western/central Wisconsin, but south of Interstate 90, the atmosphere was favorable for stronger storms. For those locations, a mix of sun and clouds and a warmer, more moist airmass coupled with a favorable low level wind profile (wind shear) that could (and would) support thunderstorms capable of tornadoes. In addition, a warm front associated with the low provided another focus for tornadic development. 

Locally, 7 tornadoes were confirmed. 3 were brief touchdowns in Fillmore Co, MN with the other 4 having longer tracks (near Charles City, IA, near Elma, IA, near Saratoga, IA, and the last around Greenleafton, MN).
