Here is our projected START times for the squall line later this evening, April 14th, 2026, which is expected to bring a chance for damaging winds 60-75 mph, and large hail 1-2"+ in diameter.
In purple, the squall line should be moving into the shoreline communities between 8 and 9:30 pm EDT. As this line moves east-southeast, the US-131 corridor and surrounding areas will experience thunderstorms starting between 9-11 pm EDT. Eventually the US-127 and I-75 corridors in red will see the squall line as early as 10 pm EDT, but as late as midnight. For the thumb, midnight or later is expected for your start time.
The random part of the graphic here is the large hatch region, which, for this map does not technically denote intensity, however, it does denote where prefrontal cells could take advantage of the early environment. These pre-frontals will need to be monitored for a very large hail, and increased tornado risk given current atmospheric profiles being primed. Not everyone will see pre-frontals, but the timing for pre-frontals will be primarily between 6-11 pm EDT. Please see our severe weather outlook released earlier this morning for exact probabilities for each region of the state.
You absolutely should have multiple ways to receive warning as you head to bed tonight. Don't rely on just the sirens. Weather radios, phone alerts, notifications for when we go live here at MSC, and even call subscriptions are all crucial ways to receive warnings besides sirens, which are only intended for outdoor use.
As always, whenever a warning is issued in Michigan, we will be live tracking right here at Michigan Storm Chasers.
