Best chance of thunderstorms for most of Michigan will be during the late night/early morning hours

The latest couple NAM4KM runs are predicting more thunderstorms tonight.

The latest runs don't have storms hitting southeast Michigan until around 5am, but it's safer to give or take a few hours with these forecast models.

Between the two runs, I'd say the best chances of thunderstorms remains after midnight, but some areas may not see anything until the crack of dawn tomorrow morning.  I don't expect anything widespread or particularly intense.  The SPC still maintains a slight risk for extreme southwest lower Michigan and a marginal risk for a larger portion of the same region.  This is due to the intense squall line propagating across Lake Michigan.  The fringes of this line of storms could swing northeast just enough to impact these areas, and one or two cells could be strong enough to maintain severe status into marginal risk area.  I don't expect much more than widespread rain for the rest of the state into the afternoon hours.

While damaging winds remain the main hazard, the tornado threat has gone up a bit for some portions of central Illinois.

As for the main event, the situation still looks ugly for central Illinois, southwest Indiana and eastern Kentucky, but the SPC has downgraded the outlook a bit, at least in terms of how widespread significant severe weather should be, though the tornado risk is now a bit higher in some areas, as discrete supercells will likely be the initial storm mode, prior to their convergence into a line.  I've not been watching this one as closely as I would if it was geared toward our neck of the woods, so I can't really weigh in very intelligently for or against the outlook, but from what I've seen of the latest models, I'd say it's mostly accurate.
