Maybe a met could answer this but, weird thing I have always wondered, if we had a huge lake above us, say it covers just north of say from Arkansas all the way to North Carolina, would we have huge snow amounts for winter because the lake wound never get really cold and it seems to me every time a cold front blasted through we would have a crap load of snow bands blowing off this lake wouldn’t we? This is not a wide lake, more long but wide enough to create bands. Just was wondering, weird thought I know. Seems like it would be a perfect area cause the lake would never get too cold so would produce a lot of updraft every cold front. And when we really got a huge front it would produce dangerous amounts of snow with temp deference’s.
