Lots of sunshine this PM – a few lake-effect stratocumulus clouds passing by. There are more clouds in NW Lower Michigan where the air is colder and the lake has been able to produce flurries. Heavy lake-effect snow is falling at Houghton, where the temperature is 9 and the wind chill factor is -10. The winds on Friday broke up a lot of ice on the Great Lakes (see thread below) and there’s a lot more open water (see satellite loop). My solar panels are cranking out a nice flow of +90° air right now. The wind knocked a lot of snow off the roofs and trees. I passed a roof collapse on W. River Dr. west of Samrick on the river side of the road in Comstock Park. We’ll have several episodes of light snow this week and temperatures will remain much colder than average. The average high temperature for G.R. is now up to 36. At 1 pm it was 24 in G.R., 21 in Muskegon and just 15 in Cadillac with flurries. The wind chill factor is 10 in G.R. and zero in Cadillac. Very cold air covering N. Plains, Great Lakes and most of Northeast (and S. Canada) this week. There is little doubt that the cold pattern will continue at least through the 2nd week of March. WeatherBell forecasting temperatures 4-5 degrees colder than average for Michigan in March – looks pretty good considering cold start first two weeks. Impressive cold in middle Asia. North America temperature anomaly for Feb. 1-22 was -0.1711°C. Global anomaly for Feb. 1-22 was +0.018C. Los Angeles may receive at least half the rain that fell in 2013 (3.60″) from 1 storm Fri through next weekend. Partly cloudy and 80 deg. in Daytona (500 race) at 1 pm, but a cold front is approaching with showers and t-storms. It’s only 58 and raining at Gainesville. A sure red flag as the storms arrive in the next 1-2 hours. 35.2% of the Lower 48 states has a snow cover...thick snow from MN-WI-MI into New England, meager snow in the California Mtns. Global sea ice now less than one standard deviation from average…Arctic sea ice extent about the same as last year, highest for the date in the last 7 years…Antarctic ice remains approximately 2 standard deviations above average.
The morning run of the GFS is relentlessly cold…it has high temperature in G.R. for the next 10 days of 16, 19, 9, 15, 18, 17, 16, 19, 17, 15. That’s probably a little too cool, but you get the general idea. The next 32-degree temp. on that model is March 11! The general storm track will remain south of Michigan, but we’ll get periods of (mostly light) lake-effect snow showers and a little snow from upper level disturbances in the northern Polar flow.
