Event narrative

This tornado formed in Antrim county 4 miles east of Alba and continued into Otsego county 100 yards SE of the Alba Rd/Old Alba Rd intersection. The tornado continued to move east northeast for almost 16 additional miles before dissipating around 1.75 miles northeast of Sparr. The tornado was rated EF3 in Otsego county based on damage surveyed in multiple locations around the Gaylord area. The first of these locations was damage in the Nottingham Forest manufactured home community. Multiple units were completely destroyed with debris blown away from the original locations of the units (DI 4, DOD 12). The second location was the business district of Gaylord where the buildings of Hobby Lobby, Maurices, and Jimmy Johns experienced collapses of exterior walls where interior walls remained standing (DI 10, DOD 8). The last location, which had the highest estimated wind speed of 150 mph, was damage found to homes on Berkshire Ln on the northeast side of Gaylord. Most exterior walls were collapsed and only partial interior walls were left standing (DI 2, DOD 8). The tornado dissipated at 1457 EST about 1.75 miles northeast of Sparr. Two fatalities were reported in the Nottingham Forest community, along with 44 injuries reported from various locations around Gaylord. The maximum path width in Otsego county was 200 yards.

Wider weather episode

Multiple thunderstorms tracked across northern Michigan during the afternoon, including a supercell thunderstorm that produced the EF-3 tornado that hit the town of Gaylord along with very large hail in other parts of the area.

Setting the stage for severe weather was a trough that rotated across the upper Midwest that developed and strengthened surface low pressure west of Lake Michigan. This system helped draw a warm, moist airmass northward across the state that helped provide the instability necessary to support severe thunderstorms later in the day. Storms initially formed along the cold front across Wisconsin during the morning hours and moved northeast across Lake Michigan, making it into the forecast area by early afternoon. The strongest line segment generated a measured wind gust of 76 mph at Frankfort Light and continued to produce damaging wind gusts across Leelanau and Antrim counties as it quickly moved northeast.

As this segment moved further away from the cold front, it began to transition into a supercell thunderstorm. This storm moved east-northeast across a very favorable environment in place across northern lower Michigan, eventually producing a tornado that caused considerable damage in the city of Gaylord. This supercell continued to trek across the area, producing baseball-sized hail in Posen.

For additional context, this was the first time in reliable recorded history (since 1950) that Gaylord was hit by a tornado. This was also the first significant tornado (EF2 or greater) in the county warning area since October 18, 2007.
