im trying to understand... so the shortwave itself, in accordance to the m.o. of this year, kind of "maxes" itself in OHV, but this PNAP and this decaying NAO regime throws the remnants and some other s/ws, such as one that might dive down out of Manitoba or Ontario, all together in this 'Legrange space'? So basically its a stalled diarrhea vorticity mess potent enough to deliver a storm on its own, but the omega block allows for the collocation of this mess with a diving s/w, and who knows what happens?
How I'm seeing what you're describing is that this is like the mid-December event, but with an enhanced western ridge and a stronger block, so basically, shoving all this vorticity together and hoping something sticks. Off base?
