2007-10-18 · near Crofton, Kalkaska, Michigan

Event narrative

The Kalkaska tornado was the first killer tornado in Northern Lower Michigan in over 30 years. It touched down just south of Crofton, and tracked north-northeast, lifting just after crossing the Kalkaska County Airport. A home was damaged in a subdivision just south of Crofton. The most substantial damage, as well as the fatality, occurred near the intersection of US-131 and Crofton Road. A large metal warehouse was damaged, a single wide mobile home was destroyed, and several stick-built homes received moderate to severe damage. The fatality and injury occurred inside the mobile home. A 29 year old man was pulled from the mobile home, but passed away at a nearby hospital. Numerous large trees were also uprooted. The damage became more sporadic to the northeast, until another pocket of concentrated damage at the Kalkaska County Airport. Several hangars and small planes were damaged, as were several homes in the area. Sheet metal from one of the hangars was deposited near the Kalkaska Middle School. Winds were estimated at 120 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.
