Great Lakes Water LevelsMay 17th, 2013 at 1:52 am by Bill Steffen under Bill's Blog, News, Weather
Lake Michigan sunset at Duck Lake – from Matt Miller at ReportIt. Check it out full screen. The water level of Lake Michigan/Huron was unchanged in the last week. We’ve had only 0.58″ of rain so far this month in G.R. and the river levels have come down. The Grand River in Grand Rapids is still a little above average (5600 cfs vs mean of 5280 cfs). The Muskegon River looks to be near average and the Kalamazoo River at New Richmond is a little below average flow now. Lake Michigan is 7″ higher than one month ago and 5″ below the level of one year ago. It’s still 22″ below the May average level, but 7″ higher than it was in May 1964. Lake Superior gained an inch in the last week (mainly from snowmelt). It’s also 7″ higher than one month ago, but is now 2″ higher than it was one year ago. It’s still 10″ below the century average for May. Lake Erie is only up 1″ in the last month. It’s 7″ lower than one year ago and 8″ below the century average. Lake Ontario is up 5″ in the last month, down 2″ in the last year and is now 5″ below the century average. Also: Check out the MODIS Lake Superior picture from yesterday (Thurs.). You can STILL see several places in the Porcupine Mts. and the Keweenaw Peninsula where there is snow on the ground! Lake Nipigon still has an ice cover. Here’s the Lake Michigan picture, the land has really greened up in the last couple weeks. Here’s a picture of the large forest fire burning in far NW Wisconsin.
Model update: The European keeps us dry until next Monday PM. Then we get showers/t-showers (not all day rains) from Monday PM thru Thursday with a total of 2.72″ for G.R. from Monday PM thru Thurs. Evening. The GFS (caribou) has 1.97″.
Oh, one more thing. I got a call from near Stanton about a large dust devil that knocked shingles off their house, barn and garage. Thurs. was a perfect day for dust devils…nearly calm winds…high sunshine…low relative humidity. I bet there were quite a few dust devils in Lower Michigan yesterday.
