Why do people keep wanting to get rid of something WE NEED!!!! This is the composite of Baltimore’s 10 snowiest months. look at the gulf of AK!!!! A vortex there promotes ridging into western N America. We want the ridge axis out west near Boise or up in the Yukon if it’s a high lat epo ridge. NOT off the west coast!!!! If you get a ridge off the west coast you get a trough axis too far west and a SE ridge pops!!! Yes if that pac vortex crashes in at times it will flood pac puke but so long as it’s off the coast it’s ok. It’s actually good. It promotes some PNA ridge. I know it doesn’t show well there because you get so many waves crashing in that it washes out the ridging you get in between but all you need is to time up that temporary ridge with a wave in the east. We want all those pac waves crashing in...those end up our storms! No it’s not a cold pattern. But our big snowstorm patterns usually aren’t. The vast majority of our big snowstorms were with patterns that weren’t particularly cold and absent the storm might have even been fairly mild! Lastly some of our worst blocking fails came because there was no trough in the N PAC and so the trough over the US ended up too far west. Yes a HUGE ridge up through Ak can dump arctic air into N America but it’s more often then not going to be directed into the west and any storm that phases and bombs will cut west of us. I am sorry if I seem frustrated but this is like the 10th post seeming to suggest we need to have what is literally our BEST snow pattern mutate into a pattern that historically is colder but normally leads to cutters. What do we want here arctic cold or snow because our perfect pattern is NOT the same for those 2 things! Our coldest outbreaks often do not feature a big snowstorm. Most of our big HECS storms do not feature any true cold. 12 9 Link to comment Share on other sites More sharing options...

Why is that? Because it’s basically a cutoff low. No northern stream involvement like the GGEM, so it’s just a bowling ball rolling across. This also means no CCB development so a very anemic precip shield. 1 Link to comment Share on other sites More sharing options...

Why is that? Trough goes negative slightly too late. If we had that northern energy start to drop South a bit sooner or if the shortwave negatively tilted a bit sooner would have been nice. with bowling ball events like this the models are going to have an extremely tough time. I wouldn’t worry one way or another until we get it to 96 hours... better news is both cmc and gfs have really good patterns after this one on today’s runs. 1 Link to comment Share on other sites More sharing options...

Heisy Posted January 2, 2021 Share Posted January 2, 2021 It’s hard to know, but the Ukie could be in a good spot here. Trough is neutral and going negative it seems. Just throwing it out there. It does seem a little cutoff from the flow so idk how north it would go. I can’t decide if it’s good or not lol Link to comment Share on other sites More sharing options...

Lately when I’ve seen verification charts it seems to be consistently doing better then the GFS. GFS has really be a train wreck lately. And the CMC has significantly improved since its upgrade. Anecdotally the para gfs seems like a significant upgrade. Perhaps the GFS retakes its place as on of the elite NWP guidance after the upgrade but honestly lately I’ve gotten to the point where I barely pay it any attention anymore. It gets about the same weight as the JMA or ICON. ETA: I see Wxusaf ninja’d me Link to comment Share on other sites More sharing options...

psuhoffman Posted January 2, 2021 Share Posted January 2, 2021 Euro is trending more and more cutoff. We need some NS phasing. A totally cutoff solution can’t work out. The flow is too suppressive and there isn’t enough antecedent cold for that kind of evolution. Link to comment Share on other sites More sharing options...

psuhoffman Posted January 2, 2021 Share Posted January 2, 2021 Well @Amped will love the day 16 GEPS that is a great look if you want brutal cold and dry. It’s not nearly as good a look for a big snowstorm though. The SE ridge is just starting to pop there...it’s likely to get worse in future times as the trough pulls west some. Look at SLP anomalies, it’s a miller b pattern. The STJ is totally cut off there. That’s a look where we are cold and wait through day and day of bone dry model runs frustratedly saying “where did all the storms go now that we got the cold”. Sound familiar? That is a cold dry look there. It’s not the worst, we could luck into something. It’s better then anything we had last year. But it’s not nearly as good a big snowstorm look. I guess if you want the pond in your yard to freeze over it’s drool worthy! And I am NOT even saying that’s coming. It’s on an island with that look. I’m just pointing out if we want a big snowstorm that isn’t the look we want. If you just want really cold and maybe some minor nickel and dime stuff I guess that’s the look you want.
