one thing i've noticed this season as a very novice hobbyist is that the upper level pattern has not been ideal. we're in need of a good vort pass with the 540 line under us. i know that's not a requirement especially for an overrunning situation, but the 500 maps just have not had that classic or even decent look which makes sense given the surface temps have also been mostly above normal.
when you sit and think about the pattern we've had for the last 2 years and leading into this winter it really isn't that surprising that we've been pretty much skunked. this past summer was loaded with 90+ days, so it makes sense that it'll take some time to get back to square one. on the bright side, this type of a dud winter should increase the chance of next winter not being quite as lame, but mother nature will decide that, not the euro.
