Tricky Wednesday Snow

Here is the Interactive Alert Map for West Michigan for Wednesday.

In talking to the National Weather Service this morning, they issued the Lake Effect Snow Warning because the snow was initially heaviest overnight for northern sections of the lakeshore.  However, even though the highest totals will be along the lakeshore, that doesn't really tell the whole story today.

This is far from a typical lake-effect setup... winds will be generally light and shifty during the day as an area of low pressure accompanied by a strong upper-level disturbance drops along the Lake Michigan shoreline during the day.  As such, we won't see bands blowing in from the lake as you would normally expect of lake-effect snow.

Instead, bands of snow will rotate around that low, even into inland portions of West Michigan.  Still, with a bit of help from the lake, the heaviest bursts will likely come along the shoreline.  But at pretty much any time, we're liable to see a heavier band of snow develop with rates of up to 1" an hour and visibilities of 1/2 mile or less.

Here are some of the most recent computer model forecasts:
