One thing I have never understood about the rending of garments etc about winter long range and temp discussion is...the average highs and lows - the AVERAGE highs and lows - are not really all that cold. Kinda warm is sorta the default state for our part of the mid-atlantic. A January 6 that is 43 for a high and 29 for a low - that's pretty much average.
AND, in a related thought, it still does snow here most years. Sometimes a lot. Even with the average days being not all that cold, relatively. 2009/10 was not all that cold - but still had the 3 mega-snows. We don't need blue balls of death cold as it were, centered over Laurel, to snow here.
