As thunderstorms move across southwest and south-central Lower Michigan, a severe thunderstorm watch is in effect until late tonight.
Instead of issuing a tornado watch, the Storm Prediction Center (SPC) issued a severe thunderstorm watch. The cause is a line of thunderstorms that are expected to mostly produce straight-line winds as they gel together. While isolated tornadoes are a possibility, they are not the primary threat from severe weather.
In Illinois, wind gusts have varied from 60 mph to the destructive 75 mph. The south-central and southwest regions of Michigan may experience the same kinds of gusts.
Until 9 p.m., a severe thunderstorm watch is in force.
The severe thunderstorm watch is in effect for all of the major cities in south-central and southwest Lower Michigan. From Grand Rapids, Kalamazoo, and Holland east to Lansing and Jackson, a severe thunderstorm watch is in effect.
Depending on whether the t-storms in southwest Michigan hold together, another severe thunderstorm watch is expected to be issued for southeast Lower Michigan in an hour or two.
You can follow the storms as they approach you with this constantly updated radar.
