Previous promising signs for the end of the month are evaporating. Ensemble trend is towards an expansive and more eastward GOA low which then pumps up ridging in south-central Canada. The unsurprising result is warmer and drier than normal weather for all of us. While I don't think this says anything about January, which probably is still going to be improved over this month, I'm about ready to write off the rest of December the way things are looking.
Some December 12 weather history for southern Lower Michigan.
1949: Balmy weather continues. For the second day in a row, temperatures set record highs at Grand Rapids and Lansing. The high at Grand Rapids was 60.
1958: Arctic air continues across Lower Michigan. Record cold temperatures include 5 below zero at both Grand Rapids and Muskegon.
2016, a snow storm wrapped up in the early morning hours after snowing for much of the previous day. Snow measurements across Southeast Michigan generally ranged from 8 to 11 inches. NWS White Lake measured 11.3 inches and Flint 10.4 making it their 9th and 15th largest single-event snow accumulations on record respectively.
2010, low pressure tracked near the Michigan/Ohio border and then northeast into Ontario. Precipitation started as rain before changing to snow. Snowfall accumulations across southeast Michigan were generally in the 3 to 7 inch range before Arctic air rushed into the region. The quick freeze created a thick accumulation of ice on many of the area roads. In addition, gusty winds of 25 to 40 mph occurred during Sunday afternoon leading to scattered power outages. Some of the higher snowfall reports included Bad Axe with 15 inches, Yale with 9 inches, White Lake with 7.7 inches, Clifford with 7 inches, Midland with 7 inches, Riverview with 6.4 inches, and Howell with 6.3 inches.
Also on December 12, 1949, the record high temperature for the day was set at 61 degrees in Detroit, Flint, and Saginaw simultaneously! This is 27 degrees above average
I was at work last night (I work at the Van Andal arena during the winter) we had around 12,000 for a concert last night. Where I was working I could see outside and there were several lines of heavy snowfall with some wind. I took a measurement and I have 5" of new snow and 5" on the ground so much better than the last snow event here. It looks to be all gone by the weekend.
