Wrap Up of Tuesday’s Severe Weather

Bill's Blog

Severe Thunderstorms blasted Wisconsin, Michigan and NE Illinois on Tuesday. Check out this picture of softball-sized hail that fell near Appleton, Wisconsin. This was one of the biggest severe hail days ever in parts of NE Wisconsin.

2.5″ hail near Baldwin

We had a number of reports of severe hail along US 10 around midday. 2.5″ diameter hail fell in both Mason and Lake Counties – with severe criteria hail (1″ in diameter or greater) at Baldwin, Wellston, Cadillac, Scottville, Custer, Colfax, Reed City, Midland and St. Louis. Trees fell across US 10 and at least partially blocked the road at Reed City.

This was hail that fell at Scottville – from Matt Carrier.

Storm Reports from Tue. 9/7/21

You can see the storm reports from Tuesday were concentrated in E. Wisconsin, NE Illinois and Lower Michigan. There was one small insignificant tornado near Minooka IL and another tornado struck SW Ontario, Canada.

Peak wind gusts: Kalamazoo 69 mph, Battle Creek 66 mph, Benton Harbor 54 mph, Muskegon Beach 50 mph, Lansing 49 mph, Saginaw 49 mph, Holland 45 mph, Charlotte 43 mph, Sparta 42 mph, Grand Ra;ids 40 mph. More W. Michigan storm reports.

Rainfall: Battle Creek 0.54″, Kalamazoo 0.46″, Grand Rapids (airport) 0.29″, Muskegon 0.26″, Lansing 0.19″, Comstock Park 0.17″, Holland just 0.01″. Some areas could have used more rain than that.

Over 70,000 customers lost power in Michigan due to the storms, roughly 3% of the state.

Lightning knocked out the Grand Rapids NWS radar:

The National Lightning Detection Network detected a 31,000 Amp cloud-to-ground stroke within 60 meters of the @NWSGrandRapids radar at 2:56:37pm ET.

This day reminded me a little of the August 2, 2015 severe event when we had winds estimated to 100 mph in Leelanau County. That day was unique in that EVERY SQUARE MILE of the state of Michigan had a thunderstorm with that system. Much of Michigan had 35-55 mph wind gusts with that line of storms with the smaller hard hit areas seeing gusts to 60-100 mph. Here’s radar:


Futurecast Tuesday 8 PM

The Futurecast did a pretty good job of bringing the storms through the area during the afternoon and evening.

Rainfall Sunday evening: 0.04″ Muskegon, 0.06″ Grand Rapids, 0.33″ Holland. Grand Rapids has had just 0.17″ of rain in the 24 days from August 13 through September 5. So, we need the rain, just not the severe weather.

They are making slow, but steady progress in restoring power in Louisiana. We’re 9 days after Hurricane Ida moved through and left over a million customers without power. They are down to 345,000 this (Wed.) AM – still a long way to go. Ida knocked down all 8 major transmission towers going into New Orleans and toppled about double the utility poles that were downed by Hurricane Katrina in 2005.
