No snow here. But there are reports of snow on the ground to the east at Lansing and on radar there is either snow or rain over Lake Michigan heading south.  At this time it is cloudy and rather windy with a temperature of 33. As of this morning Grand Rapids has only reported 0.4" of total snow fall for this season. The current mean temperature for November is now at 4.6  this month will end up being at least the 7th warmest November of record at Grand Rapids.

I just reread my post it should read that the mean temperature at Grand Rapids is now at 44.6 and that is good for a departure of +4.6

Welcome to December and the start of meteorological winter. With November now in the record books it can be pointed out that it was a mild and for our area sunny month. At Grand Rapids the mean was 44.3 that is a departure of 4.2 the high for the month was 77 and the low for the month was 22 there was just 0.4” of reported snow fall. November 2020 is now the 7th warmest November at Grand Rapids. At Muskegon the mean was 45.9 that is a departure of +5.7. The high for the month at Muskegon was 75 and the low was 24. There was 1.2” of snow fall. At Muskegon, this November is now the 5th warmest of record. At Holland the mean there was 45.7 a departure of +4.0. The high for the month was 77 and the low was 24. They do not report snow fall at Holland. As with Muskegon this was Hollands 5th warmest November of record. And to the east at Lansing the mean there was 44.1 a departure of +4.5 the high was 77 and the low was 21 Lansing reported 0.5” of snow fall. And it was the 7th warmest November of record there. Records go back at Lansing all the way to 1863. All locations now are well below average for seasonal snow fall. As as the start of December looks to be mild and dry that should continue for some time.

With all of the sunshine we had in November the question was asked what % of sunshine did we have in November. Well it seems that the NWS is not going to provide us with that information this year but it looks like at Grand Rapids there were 6 clear days 12 partly cloudy days and 12 cloudy days. At Muskegon it was 7 clear 11 partly cloudy and 12 cloudy and at Lansing it was reported as 16 clear 3 partly cloudy and 11 cloudy. So yes it was a very sunny November around here. At this time it is clear and 27 here at my house.

Nice round of thunderstorms this morning, I would think around New Years day we might have a nice Winter storm on our hands.  Congrats to those scoring some wintery precip!

@Tomor anybody, do you have a storm summary or surface low track of this storm that we had in this time frame?

I just came across this post so sorry for the late response...I have these maps saved for this storm...it sure as heck looks like the storm we just witnessed that hammered folks from NE up into MN/N WI...look at that NWS Alert Map...almost identical where the heaviest snows fell and where the defo band set up.
