Heavy lake effect snow showers continue to the lee of Lakes Superior, Ontario, and Erie tonight, with over a foot of wet snow reported in parts of the Upper Peninsula of Michigan over the last 24-36 hours. 6-12 inches of snow has also fallen over the higher elevations of western NY, with the Tug Hill Plateau likely to receive the heaviest amounts. Shown below are some radar loops from the U.P. of Michigan and western NY respectively:
Early in the winter season when the lake waters are still very warm, CAPE values of 1000+ J/kg are often achieved over the Great Lakes when Arctic air-masses move in. Thus, thunder and lightning are quite common with the more intense lake effect showers. Our plan later this winter is to document some intense lake effect snow bands downwind of Lakes Erie and Ontario, where snowfall rates can exceed 5 inches per hour!
