Wanted a thread for seasonal outlooks and related items that don't belong in the monthly or storm dedicated threads. This will be my first autumn at my new place. I was greeted last January with a very snowy period and back-to-back storms. Seems to be a theme every time I move (minus Detroit Metro). I wanted to correct something I posted a week or so ago. I said that my new locale of Harrison is not considered NMI - more so Mid-Michigan. Geographically that may be true, but when it comes to weather pattern zones, we are north of that dividing line. Here's an early season snowstorm map that illustrates pretty well where that invisible line lies: Roughly just NW of a Muskegon-Grand Rapids to N Saginaw Bay line. When a storm focuses on the S end of the NMI zone Harrison will do well. When the jack-zone is further N from M-72 to M-68 we will get some but not significant amounts. This after a case-study of 5 or 6 storms that I pulled from my memory. The 2 large storms of March 2012 and December 2012 are included as good examples. Harrison did well in March and less so in December. The closest airport with a full data set unfortunately is due east (Gladwin) and they get quite a bit less annual snowfall than here. Which caused my cousin who lives there to gripe a bit. The other data set is about 30 miles N at the Houghton Lk airport and they get quite a bit MORE than here so really neither is a good barometer of expectations my new back yard. So, I resorted to using the snow depth map video link on the set of storms I had come up with. It looks like this place gets mostly 6-12" amounts. However, Harrison has been included in all the deep snow pack historic winters that I can recall going by the same video (78,79,85, etc with 2+ foot OTG). The mostly snowless historically BAD winter of 2011-12 actually treated NMI much better. Couple map examples of better snow depth: And here's a very stark comparison map from were I was formerly in SEMI vs up here. Days since last Bliz Warning from 12-25-22 There was also a Bliz Warning in last week of Feb of 2019:
