February 1989 and December 1989 being cases in point, historic snowfalls well to our south and along the coastal southeast and midatlantic.

I think a lot of it is regression to the mean i agree with you that if this is still happening in a decade, it's time to have a serious convo 1 Link to comment Share on other sites More sharing options...

CC is undoubtedly playing a role, but I am going to maintain that simple regression is playing a larger one...at least for the next severals years or so. My mean seasonal snowfall since 2014-2015 just slipped below average after this past season, despite 7 consecutive duds....so I am defitely more open to a larger CC attribution if this should continue into next decade. 1 Link to comment Share on other sites More sharing options...

Maybe you're right, but this is still mostly regression in my mind. 7 years aso I had just concluded my second calendar month of over 60" of snowfall within a 3 year window.

40/70 Benchmark Posted 2 hours ago Author Share Posted 2 hours ago Just to be clear....I am waiting on deciding whether or not CC is already having a larger impact on snowfall than simple regression throughout the NE coast, NOT whether or not CC is taking place....or whether or not CC is already impacting snowfall in the coastal mid atl. 1 Link to comment Share on other sites More sharing options...

They always have and they always will. Many factors can absolutely influence, but they aren't a slam dunk for anything. We dont get noreasters in the southern Great Lakes and the 2000s saw above average snowfall at Detroit while the 2010s were the snowiest decade on record. It was just a great period for many.

I agree with you, though....CC definitely isn't making it any easier, but its not the only reason. But it’s been a challenge to sustain a quality +PNA ridge with the overpowering Pacific Jet. In one scenario a piece of Pacific energy digs too much out West and pumps the Southeast Ridge causing a Great Lakes cutter storm track. The next repeating pattern has been the hugger storm track along I-78 to I-84 with too much energy out west pumping the Southeast Ridge just enough for a quick change from snow to rain. The 3rd common storm track has been too much energy coming into the Western US acting as a kicker trough suppressing lows to the south. So this fast Northern Stream of the Pacific Jet has been working against Benchmark storm tracks even with blocking patterns which used to produce KU events when we had daily -5 AO readings in the past Februaries. 1 Link to comment Share on other sites More sharing options...
