With clear skies across the Great Lakes, here’s an excellent view of each lake (from MODIS/NOAA Coastwatch). Note the brown bare ground showing up in Wisconsin and even over toward Saginaw Bay. The ice is breaking up in the northern section of Green Bay and being pushed east by the prevailing wind. There is more open water now on Lake Superior and Lake Huron, with some open water at the west end of Lake Erie. Note the two biggest Finger Lakes (Cayuga Lake and Seneca Lake) never did freeze over. That’s because they are very deep lakes. Seneca Lake (on the left in the picture) has an average depth of 291 feet and a maximum depth of 618 feet (nearly three times deeper than Lake Erie). Seneca Lake also has major springs, releasing 328,000 gallons of water per minute. That helps to keep the water moving, also preventing it from freezing over in winter. As of this afternoon, Lake Michigan ice cover was at 33% and the Great lakes at 68%.
Wednesday was the first 50-degree day of the year in G.R. and the warmest day since Dec. 23rd. This is also the first time since Jan. 23-25 that we have had 3 days in a row with above average temperatures. It’s also the first time since November that we have had 5 days in a row that reached 40 degrees. Despite that, March 1-11 is still 6.4 degrees colder than average in G.R. G.R. has not had a minimum temperature above 32 degrees since 12/27. Another sunny, beautiful day today (Thurs.), enjoy.
Also, this is the latest we’ve gone into March without a severe thunderstorm or tornado watch anywhere in the U.S….46 from March 1-11 last year and last year was a low-count year for tornadoes. Bill says…it’s going to ramp up in April. Four tropical cyclones in this satellite pic. The big one is Pam. Blizzard Warning for Hawaii!!
