Climate change is very much real and is accelerating, but I don’t think that’s why the models are struggling here. The models are struggling because it’s a Miller B.
I don’t envy the mets who need to forecast this storm but as a weenie, this has been a lot of fun to track. We are less than 2 days out from the start of the storm and the models are still giving me anything from nothing to 2 feet of snow. That’s an insane amount of uncertainty this close in.
An interesting thing I noticed for my area looking at the gefs indies was there were more members that gave me nothing but also more 20+ bombs. There aren’t many giving me 6-12.
If we really get skunked after all guidance converging on a low over the cape 3 days out Im done tracking this winter and moving on to rooting for record heat.
The nam is frigid during the heaviest snows in eastern mass, 30 degrees right to the coast. If that’s right, the 10:1 maps may be underdone, not overdone.
I would go 10-15 in the 1-3 area (except the cape, there would be a sharp cutoff there due to low location), 16-24 in the 4-8 area, and 24-30 in the berkshires.
The crazy thing is models could be underestimating the QPF by quite a bit despite giving many areas 2.5+ inches. With a 970s mb low stalling over the cape I think that will increase.
could the dual low thing be the models struggling with the transfer (Miller B redevelopment)? I think the models might consolidate and merge the 2 lows into one big low as we get closer to the storm.
