MI Video:

Preferred rainfall totals with this event through Sunday morning.  2″ – 3″ will be possible from Benton Harbor through Lansing.

We do have a flood watch across southern MI from Benton Harbor towards Coldwater.

Preferred Snowfall totals through Sunday.  Large model differences lead to lower confidence than normal.  Right now, much of southern Michigan looks to miss out on the higher accumulating snowfall amounts.

Here is a look at preferred simulated radar from 1 PM today through 7 AM Saturday.

Here is a look at simulated radar guidance from 10 AM Saturday through 10 AM Sunday.

Temperatures across southern Michigan around 9 AM Saturday morning remain largely above 32 F which will limit any wintry potential at this time.  Warmer temperatures look to continue to persist until Sunday morning where temperatures begin to plummet and any moisture remaining could freeze creating slick spots.  Here is a look at a temperature loop from 9 AM Saturday morning through 9 AM Sunday morning.

Breezy conditions look to develop this weekend.  In particular, late Saturday/ early Sunday, we could see some wind gust of 45+ MPH.  Here is a look at the wind gust potential around 3 AM Sunday morning.
