April 29, 2014 Severe Weather

Overview

Hail and strong winds were seen across parts of Southeast Michigan as severe storms rolled through during the evening of April 29th. Nickel size hail was reported with the storms, along 50-58 mph wind gusts causing downed trees and power lines. These storms formed in association with a warm front that had set up across the area from a large low pressure system over the Midwest. Southerly winds and clouds clearing out during the day allowed for temperatures to climb into the 70s across much of the area creating the instability needed to help in storm development. The large weather system that brought the storms to Michigan, also brought a whole spectrum of weather from the Northern Great Lakes to the Deep South. Snow was reported in parts of Minnesota and Northern Wisconsin, while the South endured round after round of intense severe weather, including numerous tornadoes.
