The snow system earlier this week continues to move eastward, continuing to accumulate snow in eastern Lower Michigan

Eastern Michigan is definitely in line for a buildup of snow early this week. However, the tendency is for the thickest snow to continue moving east.

We are looking at several weather computer models with a given storm system. We meteorologists then use our experience to see which model seems to have the most likely forecast. As computer models converge on similar predictions, we know the models have a pretty good idea of ​​what’s going to happen.

We are now at the point this Saturday morning where the models mostly agree and give a consistent and easy to believe snow forecast. The only situation I question with this storm is a secondary part of the weather system that is expected to move west into eastern Lower Michigan. This situation certainly occurs, but it is quite rare.

So there are three changes to what you have potentially seen in the last 24 hours. The first half of the snow system will be quite weak, with temperatures of around 35 degrees eating away at accumulations. The trend of heaviest snow moving south and east towards Ontario and Ohio continues, but now barely 20 miles in the past 24 hours. The biggest change is that a second piece of the storm system is now expected to wind westward in eastern Lower, and could bring in several more inches of snow Tuesday night and Wednesday.

The snow forecast graphics below should be used to get a general idea of ​​how much snow your area could receive. The highest snow totals at the tip of the thumb can be exaggerated by an inch or two.

Here is the National Weather Service snow forecast through Tuesday morning December 1, 2020. Keep in mind that there is still a possible snowfall in the next 24 hours after 7 am Tuesday.

Snowfall in excess of 1 ″ is expected from Coldwater, Lansing, Saginaw and to the east. As you enter the Ann Arbor and Detroit areas, 2 “to 3” of snow is expected. Eastern parts of Huron and Sanilac counties could have 3 “to 4” of snowfall.

Below is an overview of the raw model predictions, showing you that the predictions are quite similar. Keep in mind that the forecast below includes the entire snow period of this weather system, with the snow ending Wednesday.

A word of warning – don’t focus on the highest snow counts. There will probably be a few inches of melting.

I would have cut everything in the 2 “heavy area because there will be compaction and fusion.

But you can definitely see where the heaviest snow will fall and what kind of buildup we can expect.

Snow starts Monday and struggles to accumulate during the day. The snow continues from Monday evening to Tuesday morning, then may pick up on Wednesday.
