You know…I was up in central PA during 2 previous winters with somewhat similar pattern and arctic cold and I was super dry for a month while down here was getting all the snow. The snow rides the boundary in thaw regimes and we ended up too far into the cold to get those cold boundary waves but not far enough north to get the pure arctic boundary waves. We have been in a dead zone.
I know, honestly when I post the snow maps it’s because I’m lazy and don’t have time to do a full breakdown of the real maps or answer the 50 questions you get if you just post a promising h5 plot without any editing and analysis.
Don’t worry we know that window is yours. Brooklyn just does quick drive byes he don’t read up. He probably only saw posts about PD in the last hour and figured he’d enlighten us.
It’s not quite as bad when it’s at least a red tag doing it. Some of the kids who post some model run 17 hours after it was discussed gets super annoying.
The AIFS eps has a known under dispersion issue. So when it’s good it can be very good. And then it flips to nothing a run later. Thats a flaw with its ens. Any well distributed ensemble system from 200 hours isn’t going to snow some super crazy signal because at that range there should be a lot of variance to the perturbations.
Can we compromise on 50? DC metro deserves it…but man don’t F over the northern fringes for the southern portion of our sub. They are doing like 200% better wrt climo the last 5 years than I am.
I showed you yesterday how the EPS was so close and if that Baja wave just ejected a bit more energy…boom. Once in a long while I know what I’m talking about.
There are still 5000 little things that can go wrong. Over amping becomes an issue if it ejects too much. Remember Jan 25! This time we won’t have arctic cold to offset a hostile track. But when guidance was squashing the thing I knew there was a good chance it came back because it needed a slight adjustment in a way models often are biased.
In fairness it’s run 4 times a day and taking every time it spits out one random run at 200+ hours with snow isn’t fair to categorize it as “predicting a snowstorm”. This is only the 3rd time it was consistently hitting a specific storm for multiple runs. One is them ended up good. The other not. We will see.
@Stormchaserchuck1 the 2 times recently we got significant Atlantic side help during the 2nd half of the winter during a -PNA period we did stay cold and somewhat snowy. Late Jan early Feb 2021 and March 2018. I don’t think the blocking coming up will equal those two BUT we have a much colder antecedent airmass also so those two might wash out.
