that trend towards more of a +PNA as we creep into the more standard long range is also the exact opposite of what we saw last year. makes sense given that we're in a Nino now
yup. this run has the works: Arctic ridge bridge, -NAO, -EPO, -AO, split flow, cross polar flow, 50/50 ULL, TPV in southern Canada, and a potent southern stream wave
what a weenie pattern. the -NAO is a game changer if it's real. goes from cold and active to bigger storms quickly
the split flow with vorts undercutting the -EPO is also great to see. all around really nice stuff
also, a warm Canada doesn't mean that it can't be cold here. it's a silly argument. +10 up there can be -5 down here... the GEFS shows that well. this is often the case in El Nino winters. Feb 2010 is actually a glaring example. Canada was absolutely blowtorched and BWI got 50" that month
idk man, does this not look like a massive change? the pattern is fundamentally different in the Pacific. you go from an AK trough regime into a AK ridge regime
how the fuck is January 1-4 mid-month? what is going on in here. do we need to redefine dates?
@qg_omegaone of those is literally for Dec 28-Jan 2. explain to me how that isn’t around the end of December
i don’t think people realize that when you LR forecast, you are going to be wrong more than you’re right. just the way it is
a lot of the people that troll don’t even really make any calls, either. they just bump troll
regardless the change to a better pattern is still moving up in time. don’t really see any changes there
yup, the anomalous ridge over central Canada forces confluence and leads to cold air crashing in. a rare setup, but it's viable if the GFS is correct with the amplitude. my bet is no, but it's worth watching for sure with an amped pattern like that
better chances likely come afterwards
might be able to pop some confluence out ahead of the S/W like the 18z GFS OP does. would make sense given that HP is favored downstream of a ridge like that
afterwards, the GEFS seems to have pretty much caved to the EPS in the longer range. -EPO, neutral NAO, temps are cold enough, and there's also split flow. nice pattern there
i mean, this is a gorgeous look on the GEFS still. strong ridge into northern Canada, -EPO forming, NAO trending neutral, and split flow. very active and more than cold enough
