I'm fairly certain (didn't bother to look, admittedly) that MDT did not get to single digits last year - I know my low for the season last year was 13, which is the warmest, coldest night that I can remember. This winter has been sort of comatose. There just has not been any wild fluctuations. Really, I'd wager that 80% or more of the days this winter has featured highs between 35-45. No thaws, no arctic snaps. Just the same thing over and over.
As far as the storm pattern and potential lack of wintry precip, I thought Hoffman made a great point yesterday. All guidance started weakening the system for tomorrow night/Sunday morning, which is allowing some amplification of a little vort passage on Monday. This in turn will dampen the flow for Tuesday's wave and also prevent high pressure from establishing a reinforcement of cold air. That little vort for Monday wasn't showing on guidance until the past 24-48 hours, and it's helping to screw up the pattern for Tuesday.
