January Medium/Long Range: A snowy January ahead?
brooklynwx99 replied to mappy's topic in Mid Atlantic
yeah, this really isn't warm. can see a cutter beating the gradient down for a colder system following up -

be still, my beating heart -
much better phasing signal with the super amplified +PNA

it doesn’t really look all that warm with the -EPO bringing Arctic air into the CONUS, the TPV nearby, and some weak -NAO in there too i wouldn’t even call it a SE ridge. the core of it is over the Caribbean
-
as of right now the 19th looks like a light to potentially moderate event if the vort amps more as it swings around, which is totally possible. looks like greater potential around the 22nd with a phasing kind of look as the TPV eases and PNA ridge remains strong. more of a signal for some southern stream vorticity to get left behind for that timeframe as well

we've seen the Pacific jet get stronger time and time again as we head into the medium range so the retrogression might just be overdone -
yes they are. a cutter pattern has the mean storm track over the OH Valley with a deep -PNA and strong SE ridge. cold and dry has the mean storm track out in the Atlantic with a deep trough over the East. two completely different things. this is a cutter pattern: also, it doesn't even look dry. precip is about normal and ensembles are still showing a signal for that 18-22nd timeframe. I swear some of you are just making stuff up
-
so apparently we've gone from a "cutter pattern" to a cold and dry one in like two days? how does that happen? those are two completely different patterns
-
I wouldn’t expect something as ridiculous as 13-14… the pattern just reminded me of the one largely in place that year
-
seems like -NAO blocking patterns are dry and suppressive, -EPO patterns without blocking are cutter patterns, and actual cutter patterns with -PNA are super cutter patterns. what exactly is the pattern that will produce snowfall for some of you? what are some of you looking for exactly
-
“trying” to flex doesn’t count. the ridge is super flat and there’s TPV vorticity in southern Canada that will make it more difficult for storms to gain latitude the gradient is largely south of us. sure, you can get a cutter, but calling it a cutter pattern is reductive. cutter patterns have deep troughs in the west and strong ridges in the east. that is not the case here

i mean, the angst over it is a bit much considering that the initial wave likely drags the baroclinic zone south. that’s common in these -EPO patterns. a two day warmup and a little rain before a potential colder storm isn’t an indictment on a pattern that does look cold and legitimately active who knows, that initial wave could also trend flatter. it’s 8 days out
-
acknowledging that the upcoming pattern is cold and active isn’t hype at all. maybe we have to endure a little rain. not a huge deal and it isn’t indicative of the pattern not being conducive for snow also, neither are realistic. i don’t think any of you have seen me posting long range OP runs regardless of the outcome

i mean DC got its 4th largest snowstorm this decade. just crappy luck that a TPV lobe moved to our north. the main threat area was NYC to RIC and it was the southern half of that envelope
