This is the snow cover maps from yesterday compared to last year at this time. As you can see we are showing less coverage than last year, in fact, the whole of the northern hemisphere is showing negative values in comparison to previous years (chart below)
With the snow predicted for the rest of the week, this will probably end up as our snowiest month for the winter which isn’t saying much as we are well below normal thus far for the season.
We have the moon peeking out through a thin layer of clouds this morning with a temp of 24.4° at 6:30 am. Forecasted temps for today will be in the mid-30s with a brisk west wind at 10 to 20 mph which may produce a few snow flurries.
Accumulating snow is forecasted to return to the area Wednesday Evening. The snow will be spreading in from the southwest. The snow will persist into Thursday. Roads may become snow-covered and slick. Impacts could develop as soon as the Wednesday evening commute along Interstate 94 with widespread impacts possible Thursday.
On Friday our temps will drop into the teens for daytime highs and the single digits on Friday night. This will be short-lived as temps recover back into the 30s by Saturday.
This is the morning forecast discussion from the NWS:
Snowfall accumulations for our area in southwest MI can be expected to begin by Wednesday afternoon and evening then linger into Thursday. As an arctic front moves through our area Thursday, temperatures will steadily drop into the teens by Thursday afternoon. Overall snowfall accumulations between 2 to 4 inches are expected with possibly up to 5 inches south of I-94. Winds gusting towards 20 mph Thursday afternoon may result in some blowing and drifting snow with reduced visibilities. Altogether slippery road conditions are the expected main impact Wednesday night into Thursday with reductions to visibility developing Thursday. -- Lake Effect Snow Thursday Night and Friday -- Following the passage of the arctic front on Thursday, lake effect snow will be invigorated as 850mb temps drop to near -20C leading to delta T`s around -20. With sufficient moisture within the DGZ alongside plenty of lift, snowfall for lakeshore areas looks likely. Overall accumulations are still questionable as smaller flake sizes may limit amounts. Regardless, travel impacts can be expected. With temperatures Thursday evening in the teens dropping into the single digits overnight into Friday, snowcovered slippery roads are expected with less effective salt mitigation. Winter headlines will likely shift towards lakeshore counties for this time period.
