Another great picture here from Jack Martin. Click the pic. to enlarge. This is Lake Michigan Tuesday afternoon. You can see the exiting cirrus clouds. Shortly after midnight early Tues. AM, Muskegon reached 66 degrees. That was not only a record high temperature for Dec. 4, but it also topped the 64 on 12/2/1982 for the warmest temperature ever recorded at the Muskegon Airport in December. Grand Rapids set a daily record high of 65 at 12:01 AM. With the warmest temperatures right around midnight, the 65 counted for both the 3rd and 4th. The first 4 days of December were 16.25 degrees warmer than average. This is record territory, but not unprecedented. In 1998, we had a 9-day stretch from Nov. 28 to Dec. 6 when the mean temperature was 22.1 degrees warmer than average. That winter we had 49.7″ of snow between 12/31 and 1/25 and we wound up with 76.7″ of snow – a little above average.
Overnight Model update: The NAM (caribou) gives G.R. highs of 40/40/45 over the next 3 days with 0.13″ of rain on Friday. The GFS has highs of 38/41/43 with 0.20″ of rain Thurs. night into Friday and maybe a half inch of snow Friday night…maybe. Then it gives us 1.02″ of rain late Sunday to late Monday. The precipitation may end with an inch or two of snow if the cold air can get here before the precip. exits. Then we get another 1/2-1″ of snow Tues. night into Weds. From late Monday thru Tuesday night, it’s plenty cold enough for snow on the model. The European has upper 30s/low 40s/mid 40s for the next 3 days in G.R. with 0.08″ of rain on Friday, 0.04″ on Saturday and 0.37″ of rain on Sunday, which could end with some snow Sunday night/Monday. Like the GFS, it’s plenty cold enough for any precip. to be snow from early Monday thru at least Tues. evening and probably beyond. If we can ever get other parameters working, the lake-effect would add to this. The sun will be out for most of the day today…enjoy…it looks pretty cloudy from Thursday into early next week as we get into a wetter pattern. By the middle of next week…the cold is getting closer (-38C northwest of Lake Winnipeg less than a mile off the ground). Check out the -72 forecast for Greenland. The European model forecasts a bit of rain for the Ohio Valley. Finally, here’s Typhoon Bopha hitting the Philippines.
