The Great Lakes are off to a good start this season with the second major lake snow event occuring off all 5 lakes.
I again targeted the Gaylord area yesterday morning through last night to watch the fun. This event in Northern Michigan was a NW wind veering to the NNW then almost North wind event at the present time shifting the snowbands over a wide area. Several areas have received 1 foot amounts..with areas East of Lake Erie close to 30".
First pic shows that the NW wind created a feeder band from Lake Superior that intensified as it picked up moisture from Lake Michigan before impacting the higher hills inland. (Sometimes, this Lake Superior connection actually beings over Lake Nipogon which is NNW of Lake Superior.) Note how the band became wider inland...another common lake effect feature. Note that at the very top and on the East side of the feeder band is Beaver Island. This island creates all kinds of interesting shadow/wake effects in the horizontal roll convection that crosses the lake there. It is very common that NW/SE oriented bands will form on either side of Beaver Island with a visible/persistent precip shadow visible for dozens of miles downwind of it.
