We have a Slight Risk (in yellow) of a severe storm south of a line from S. Haven to Detroit and a Marginal Risk (in dark green) south of a line from Muskegon to Bad Axe (in the Thumb) SPC says:
"Thunderstorms are ongoing this morning from northern IL/southern WI into Lower MI...resulting bowing line segments may produce isolated damaging wind gusts...Then, thunderstorms are expected to develop rapidly during the afternoon...Primary severe hazard is expected to be damaging wind gusts, particularly if organization into a convective line occurs. Hail will also be possible...predominantly linear mode could limit the tornado potential, but vertical wind profiles still suggest a low-probability threat, particularly across IL and northern MO."

The above map is the Severe Weather Reports from Wed. 5 13 20. There was one tornado in Texas, 8 reports of wind damage (gusts to 70 mph) and 27 reports of severe-criteria hail, up to the size of tennis balls.
If you didn’t get a chance to see our special on the 40th anniversary of the Kalamazoo tornado, it’s up online now here.
BTW, this is the first lightning/thunder in Grand Rapids for the last two weeks. We’ve been in an unseasonably cold pattern…the coldest May 1-12 ever in Grand Rapids, 8.5 degrees colder than average. The storms (until today) have been south of us. It’s also been unusually quiet. We have had only five relatively small tornadoes in the U.S. in the last 8 days..unusually for May – which is often the month with the most tornadoes in the U.S. However, we have had 73 fatalities this year from tornadoes in the U.S. That’s more than the fatalities from 2018 and 2019 combined.
