Light snow will develop this morning with the largest amounts in north-central lower Michigan. Amounts will range from an inch or less along I-94, to 2 to 3 inches up toward through central Michigan. Roads will likely become snow-covered and slick this morning.
After today’s snow or lack thereof we will turn our attention to tomorrow evening’s system which may bring another three or more inches to southern lower Michigan. We should see some sort of advisory or warning going up later today or early tomorrow. At this point, the heaviest snow will be between 196 and I94 though as time moves on this may move north or south. Below are the model guesses:
- 1 to 2 inches of warm advection snow Today Still on track to pick up a warm advection burst of snow today although amounts should be cut down a bit by dry air place this morning. Still, we should get an inch or two across most of the forecast area. Impacts to travel should be limited as sfc temps in the lower 30s this afternoon. - 3 to 6 inches of f-gen snow Monday night/Tuesday Frontogenetic forcing sets up on Monday night into Tuesday across the central and southern forecast area is sufficient for 3 to 6 inches of snow from I-94 to near I-96. There could be a sharp northern edge to the snow as is the case with dry and cold air advecting into the storm from the cold anticyclone from the north. That northern edge could be across our central or northern forecast area. The frontogenetical forcing weakens and the snow tapers off Tuesday night with hints of an upper low and weak surface wave bringing a batch of light snow through on Wednesday. This was now showing up in the blended POPs. It looks like the storm that ejects out of the western CONUS longwave trough on Wednesday will track well south of Lower Michigan.
