The first picture is a Lake Michigan sunset from Mary at ReportIt. It looks much better full screen. The second picture is the MODIS satellite picture from Friday. Here it is full screen. You can see the muddy water that’s come out of the Grand River along the shore and extending out for a good 3-4 miles. It looks there might still be a little ice in Green Bay. Saturday we had our first 70-degree day in G.R. That was 43 days later than our first 70-degree day of 2012! The GFS has backed off on the cold and our temperatures will be warm early in the week and cooler, but not terribly cold later this week . Here’s the GFS maps. May is the month when you can get these “bowling balls – closed low pressures that are detached from the main Polar Jet and they move very slowly and tend to wobble around. It would be good if this system brought needed an substantial rain to KS and OK. I think west Texas will continue to be the center of the drought into early summer.
G.R. thru 4/27 is 4.7 deg. cooler than avg. for April. Rochester MN had their first 60-degree day of the year on Friday – tying 1951 for the latest first 60 deg. ever. That year turned out to be a cool summer for the Great Lakes. G.R. is at 66″ of snow for the winter and 10.76″ of precipitation for April.
