yeah, the ridge amplitude lessening is kinda making this more difficult. we’ll see if it corrects back or if it’s more of a definite trend downwards today
since it's weaker this run, heights in SE Canada remain much lower, which allows the second wave to amplify into a colder airmass. it's a MECS verbatim
very strong ridging will encourage some kind of low pressure (potentially strong) somewhere over the E US. not sure how the first wave will impact the second as the ridge in the west builds, but models are beginning to key in one the second one more and weaken the first a bit. the pattern is favorable for some kind of coastal. the jury is out on how and where a storm forms (if one even does)
yeah the wave spacing on the ECMWF ruins it verbatim. seems like models today are keying in more on the second wave rather than the first so we'll see if it continues
that is true, I generally agree... it has been done before, though. i would kinda argue that you want a bit of a WAR. things can become suppressed if you have a massive PNA ridge alongside a large 50/50, especially up by you guys. that's often how you get the NYC-DC specials
can't really ask for much more from a general synoptic perspective here. 2.5-3 sigma ridge in an ideal spot with a potent vort diving into the Plains. details will get ironed out but it's nice to see the models keying in more on the second wave

we have had a similar longwave pattern for Jan 2022 and Jan 2014. tall ridge over the Pac NW / NW Rockies, deep trough with TPV interaction into the OH Valley, and a WAR pushing into Nova Scotia. not calling for a MECS or anything but there are similarities
i could see a weaker vort that drags the baroclinic zone south and brings in a better airmass before a larger system on the 21-22. not sure if that would be considered two storms, per se
