A Foot of Lake-Effect, ThunderSnow, Waterspouts

Our first lake-effect snow event of the season will occur Sunday night into Monday, and it could be a doozy, because the lakes are so warm this time of year. I want to quote a couple of the AccuWeather.com news headlines that have some interesting specifics:

First, from our Breaking Weather News Page (PREMIUM | PRO):

Next, from our Winter Weather Discussion (PREMIUM | PRO) today:

We've talked before about how lake-effect snow forms (and how it's like putting hot lasagna in the freezer). The convective nature of the rising air and the friction of the land will aid both the formation of lightning (and hence thundersnow) as well small hail, and the potential for waterspouts. I'll keep you updated here on Monday as to where lightning has struck, if any waterspouts have been sighted, and what the maximum snow amounts are.

It will be interesting to see how widespread the snow will get and how far south and east it will go. Our best bet to see these possibilities will be the high-res 4-KM WRF Forecast Model [JessePedia], which only goes out 48 hours and just catches the beginning of the outbreak as of today, showing flurries down the spine of the Appalachians, and heavy snow to the south and east of the Great Lakes.
