EF2 Tornado — Oscoda, Michigan

2007-10-18 · near Luzerne, Oscoda, Michigan

Event narrative

The Oscoda County tornado may have been the strongest of the six on the day. Thankfully, it spent almost all of its lifetime in unpopulated areas of the Huron National Forest, though that makes its strength difficult to estimate. Tens of thousands of trees were estimated to have been uprooted or otherwise downed, and many power lines were downed. About 16 structures were damaged, mostly outbuildings or cabins. Three cabins, near Cherry Lane and Cherry Creek Road, were destroyed. Winds were estimated at 115 mph, making it an EF2.

Wider weather episode

An historic tornado outbreak rocked Northern Lower Michigan on the afternoon and evening of October 18th. The day started out cool and rainy, but a dry slot aloft allowed sunshine to break out in the afternoon. Temperatures rose into the lower to middle 70s in parts of the area. The warm and humid air was unstable enough to fuel multiple rounds of thunderstorms in the late afternoon and evening hours. There was a tremendous amount of shear in the atmosphere, and many storms quickly became supercells with rotating updrafts. This was an environment conducive to tornadoes, as several lines of discrete supercells crossed Northern Lower Michigan.

Northern Lower Michigan had a record six tornadoes on the day. The previous high was five, set on June 17 1992. Unfortunately, the Kalkaska tornado produced a fatality. That was the first tornado fatality in Northern Lower Michigan since March 30 1976, when a single death occurred in Ogemaw County.
