Overview

A cold front tracked across southeast Michigan during the late afternoon-early evening hours of April 4th, leading to two lines of thunderstorms each producing pockets of damage south of I-94. Despite weak instability, the strongest cells were able to capitalize on low level wind shear near the intersection of the warm front and marine boundary layer, leading to rotation along the line. Storm surveys were conducted in both Whiteford Township (Monroe County) and Van Buren Township (Wayne County). The Monroe County cell was determined to be straight-line wind damage due to a divergent pattern. The Wayne County cell was determined to be an EF-1 tornado based on the damage pattern, radar data, and video evidence. This system also produced heavy rain with widespread storm totals of 1 to 3 inches and localized reports up to 4 inches. This event followed a wet pattern that occurred through the days prior, with widespread 5-day rainfall totals of 3 to 5 inches across much of Lower MI.

The tornado started just south of Martz Rd between Rawsonville Rd
and Hoeft Rd. It first flipped a hayride trailer and continued
northeast toward Hull Rd. EF-1 damage occurred along Hull Rd with
the greatest concentration of EF-1 damage along and just south of
Hull Rd between Elwell Rd and Bak Rd. This damage included
multiple trees uprooted and snapped, telephone poles snapped, and
a large barn wall blown out. The tornado continued northeast
crossing Sumpter Rd producing EF-0 damage with scattered large
tree limbs and power lines downed. The tornado lifted right
before reaching Savage Rd.

Environment

It was another highly conditional setup for SE Michigan, with low confidence in surface destabilization. Leading up to the event, the main concern was for damaging winds with a secondary risk of a brief, spin-up tornado if storms interacted with the marine boundary layer. The decision to include Monroe County in Severe Thunderstorm Watch #97 came as a line of thunderstorms over northern Ohio lifted into extreme southeastern Michigan. There was plenty of low level shear in the synoptic environment and backed surface winds near the shoreline, so the question was always about northward progress of the warm front/instability. SPC mesoanalysis (Figure 5) was not overly impressive with the SBCAPE magnitude (< 500 J/kg), but at the end of the day proved to be enough for storm-scale dynamics to overcome.

The first line of storms produced a pocket of straight-line wind damage in southwest Monroe County near Lambertville in Whiteford Township. The line quickly encountered stable air as it moved north of the front/into the marine layer, which prevented more widespread damage. Radar presentation showed a defined wind bubble on the TDWR of nearly 60 knots at 800 feet, while an unbalanced velocity couplet pointed toward straight-line winds as opposed to a tornadic circulation. This was confirmed by a storm survey, noting a divergent pattern to damage consistent with straight-line winds. A second line of storms developed along the cold front, roughly 75 miles behind the leading line. This was another shallow line of storms with minimal lightning activity that was able to take advantage of enhanced streamwise vorticity near the front and marine layer. Tornado Warnings were issued as rotation developed briefly along multiple spots in the line. The strongest area of rotation produced a short-lived EF-1 tornado that tracked northeast through Van Buren Township in Wayne County, near Belleville.

Finally, this event produced minor flooding across southeast Michigan. Numerous River Flood Warnings were issued, in addition to Flood Advisories where 1 to 3 inches of rain (locally up to 4 inches) occurred throughout the day. There were numerous reports of standing water covering lawns, roads, and other low-lying areas. Flash flooding, however, was not observed.
