This blog is really more about showing those who do not know about the SPC HREF model. I have some of the key charts from today’s HREF that show where the severe storms are expected, the strongest winds, and heaviest rainfall.

Here is a link to the SPC HREF model.








I updated my story about the severe storms since the NWS has now reported 8 tornadoes in Michigan on the 24th of August. The strongest was an EF-2 near Webbrvillle







The Storm Prediction Center has put most of the southern 1/3 of Lower Michigan an enhanced risk for severe storms today (mostly late morning into mid afternoon). Locally heavy rainfall is expected too.




Most of the rainfall today will be from late morning into mid afternoon.
My experience in forecasting over the past 46 years tell me that for Southwest Michigan convection during the spring and summer months, warm fronts, stationary fronts and surface waves bring this area the most rainfall. Cold fronts bring us the least (typically). This event is warm front with a surface wave that develops into a surface low. This tells me most area should see meaningful rainfall today.



I added the Colon EF-1 Tornado to the storm summary plus the CoCoRaHS rainfall reports for the storm.









Heavy rain with localized flooding occurred over southern and central Lower Michigan on the evening of the 12th of July. There were also reports of damaging winds, a tornado near Colon and a few funnel cloud reports.






Severe storms during the evening of June 29th 2023 brought down trees and wires. Locally heavy rain causes some roads to be closed for a while.
