Ice Growing Again on the Great LakesMarch 17th, 2014 at 9:16 pm by Bill Steffen under Bill's Blog, Weather
Click on the images to enlarge. These are the MODIS satellite pictures taken yesterday (Sun.) and today. Skies were mostly clear over most of the Great Lakes, so we have a pretty clear view of the ice on the lakes. If you look at this graph, you can see that ice cover has actually increased on Lake Michigan over the past few days with the cold air, up around 15% coverage. Houghton was -20° Sunday morning, the coldest temperature ever so late in the season and 37° colder than average. Through Monday, Grand Rapids is 10.5° colder than average for March. This is the 5th consecutive month with colder than average temperatures in G.R. (Nov. was 2.3° colder than average, Dec. 3.1° colder than average, Jan. 6.3° colder than average and Feb. 9.1° colder than average). We have now hit 100 consecutive days with an inch or more of snow on the ground in G.R. and 98 consecutive days with 4″ or more of snow on the ground. Tomorrow Muskegon hits 60 consecutive days with 12″ or more of snow on the ground. The long range outlook continues the cool pattern, with a few days getting to average temperatures and most days staying below average. The 6-10 day European looks “outrageously cold“ for Michigan and the Great Lakes.
Also: Truck flips over on Hansen Bridge in Idaho. Freezing rain has caused traffic accidents and power outages in parts of North Carolina. Surf’s up in California. Japanese model keeps the Great Lakes cooler than average into at least early April. Here’s what the White House looked like on St. Patrick’s Day morning – with the fountain turned green. 10-day is crazy-cold. Winter Storm Warning E. South Dakota across Minnesota to NW Wisconsin.
The overnight European model gives G.R. a total of 0.44″ of precipitation thru Thursday AM – most of it rain, with maybe an inch of snow at the back end. The GFS plot has 0.36″ with the same inch of snow as it ends. Watch for slick spots on the roads Weds. night into early Thursday.
