Severe Weather May 26, 2015

Overview

Showers and thunderstorms developed in a seasonably warm and moist airmass over Southeast Michigan during the afternoon of May 26. As extensive morning cloud cover thinned, pockets of heating allowed marginally unstable conditions to develop. Storms formed ahead of a shortwave trough racing northeastward across the Upper Midwest. The marginal instability did not allow for much vertical growth of storms which limited the overall severe weather threat, but just enough wind shear existed for a couple of fairly organized storms to be able to produce strong to severe wind gusts. A severe thunderstorm watch was issued at 3 pm for Lower Michigan to cover this threat. Severe thunderstorm warnings were issued for Monroe and Wayne counties, with a few wind damage reports across those counties.
