Yeah I don't get this idea that winters are struggling or going to struggle to produce large snowstorms or prolific snow events....the empirical evidence supports the opposite frankly. Maybe someday it will be true way out into the future.
This is despite also there being empirical evidence that the Hadley cell has expanded...it hasn't stopped huge events of all kinds in clocking us...even this year, we got a meandering slow massive cutoff low that assaulted us for 3 days in early December with two distinct pulses.
