Thunderstorm Wind in Scott County, Minnesota

Measured from personal weather observing station.

Scattered clusters of storms resulted in large hail over portions of east-central Minnesota during the afternoon on July 13. One storm produced a brief tornado in Rice County. A line of storms then developed over northwestern Minnesota during the evening and travelled southeast across central Minnesota throughout the night. This line led to numerous reports of hail and wind damage before it weakened as it moved into Wisconsin.

An unusually warm and humid air mass resulted in heat index values greater than 100F across portions of southern and western Minnesota during the afternoon and evening of July 13. The combination of several thunderstorms and persistent cloud cover kept heat index values in the low to mid 80s further east.
