Episode Narrative Despite surface temperatures only being in the 60s, with dew points in the 40s ahead of an approaching surface cold front, a pocket of cold air aloft associated with an upper level low generated enough instability to support thunderstorms. These thunderstorms mainly produced marginally severe hail and wind for a brief time in the early to mid afternoon. However, one thunderstorm managed to acquire supercell characteristics and produce a brief tornado in southern Lake County. This tornado was the first recorded tornado in Lake County, Minnesota since September 16, 1992.
Event Narrative A brief tornado occurred in a heavily forested area west of Silver Bay in southern Lake County, roughly along a 2 mile stretch of US Forest Service Road 107 (Kane Lake Road). There were a few pine trees snapped or uprooted, a few ash and birch trees uprooted, and some broken birch tree limbs. The damage seemed to be focused into narrower corridors within the broader tornado path, possibly indicative of smaller vorticies within the overall tornado. This matches well with an eyewitness report that was received of a rotating wall cloud with some small funnels occasionally protruding from the base. No structural damage was observed. [DI 28 (TS), DOD 3, LB-EXP, Est. Gust 70-80 mph].
