Great Lakes Snow CoverApril 23rd, 2014 at 11:32 am by Bill Steffen under Bill's Blog, Weather
We’re a week from May and here’s the latest snow cover in the U.P.: 26″ Mohawk and SE of Calumet, 20″ near Houghton, 17″ Munising, 13″ Ishpeming, 11″ Paulding, 10″ Michigamme, 9″ Big Bay, 6″ Newberry, Jacobsville, Marquette (airport), 5″ Ontonagon, Gladstone, 3″ Watersmeet. Snow cover is now at 5.9″ of the Lower 48 states. (click on the images to enlarge – the first is Great Lakes snow cover from NOHRSC, the second is North America snow cover and ice cover from NOAA (still a lot of ice on Lake Superior). Great Lakes ice cover on 4/22 was 33.9% (the most ever this late in spring). Ice cover on Weds. 4/23 was at 17.2% on Lake Michigan, 59.5% on Lake Superior, 31% on Lake Huron, 10.2% on Lake Erie and 1% on Lake Ontario. The GFS says that April ends and May starts cool over much of the Central U.S., including Michigan. Again, don’t be in a hurry to plant this spring – the threat of frost will probably linger into early May. Here’s the Michigan Tech. Trail Cam – still looks like mid-winter. Here’s the ice around Granite Is. in Lake Superior. Click here for webcams around Upper Michigan and Lake Superior. Here’s the Snowman Cam from Krupp’s Resort at Twin Lakes – lots of snow left…lots of ice on the lake. Mt. Bohemia is up to 347″ of snow for the winter – and they’re not done yet. They will be open for skiing through at least the first weekend of May. Boyne Mt. is scheduled to be open this coming weekend – one of their longest seasons ever (started on 11/15 – so they are headed toward nearly 6 months of skiing. Ski Brule is also going to open for at least one more weekend.
Global sea ice extent is now well above average (a significant increase since 2012). Arctic ice remains below the recent average, but significantly above the level of April 2007/2008. Antarctic ice extent continues to set daily records. The extent is much greater than one year ago, much greater than average (well beyond two standard deviations from the recent average) and it continues a steady climb from the mid 1980s.
