@narnian78, I was really saddened to hear of these tragedies in MI. In SW Ontario, we had warnings last night of terrifically strong tornadoes in Michigan, so as to be on the alert here, but the meteorologists said these severe storms should weaken as they enter our province. Ontario Storm Watch wrote this at 9 last evening:

Storms often weaken after sunset as the atmosphere becomes more stable, so we’ll be watching closely to see if any of the embedded stronger storms can hold together as they approach the [Canadian] border. Not to mention the cold lakes that act as our storm shield early in the season.

Good that you are getting abundant rain (with more on the way next week), @Pete, but sorry to hear of the flash flooding in some areas. 

We have an unusually warm day today for March in our area (one can almost feel a tad of humidity!) —>18C / 64.4F; not so warm tomorrow; warm-ish again the beginning of next week, with rain on Tuesday, which will usher in a more comfortable cold front from here on in for a good chunk of the rest of March, including snow at times.
