If not then, there is a long range threat being honked by GFS/EPS around the 24th/25th (after a big lakes cutter reloads the pattern next weekend ) This threat appears to be a strong Miller A with ample cold air around - which could be major snowstorm for 90+% of this forum. Obviously we are WAY too far out to be talking specifics about it, but the overall pattern around that time looks ripe. MJO will be phase 8, -NAO will be freshly reloaded with a nicely placed ridge out west. Lots of time for things to change clearly, but the threat potential looks to go out at least another 2 weeks (outside of a brief few day warm up as the pattern reloads late next week) I was just going to ask about the MJO. I feel like it hasn't been mentioned too much lately, maybe because we have been focused on having a -AO/-NAO. Hopefully we still have a chance at something before March!

jayyy Posted February 11, 2021 Share Posted February 11, 2021 Tuesday looks like it may be ripe for people west, and perhaps even along 95 - north of DC. Trends looks really good with 3+ days to go. I’m actually quite excited for that one up this way. 3 Link to comment Share on other sites More sharing options...

Very little precip north of EZF. thing is with temps in the 20s (assuming that holds), then it really wouldn't take much precip to turn things into a skating rink sunday. tuesday does look interesting on the gfs. the latest cmc shows the squashed version. i would think suppression/weaker, but still workable system would make more sense, but we'll see what the 12z's have to say. 1 Link to comment Share on other sites More sharing options...

Totally agree, but again looking at the surface temps for us near the cities, each run is bumping a degree or two. Now its 29 or 30 with precip in the area. We've moved away from the mid to upper 20's look (at least on the Nam). Slow trend all season has been to warm the surface and decrease the precip. That's all I'm saying.

Heisy Posted February 11, 2021 Share Posted February 11, 2021 The out of range NAM looks to be doing a similar progression as CMC. Just something to keep an eye on, it could completely screw up the spacing and the event itself. Link to comment Share on other sites More sharing options...

WinterFire Posted February 11, 2021 Share Posted February 11, 2021 2 hours ago, psuhoffman said: I totally get the frustration in DC. Thing is it’s been a failure of boundary temps not pattern. I don’t know what to say. This has been the pattern since Dec 1 and the last month! This looks like a match to every big DC snow period. And we’ve had perfect track after perfect track SWs this winter. I count about 5 storms that frankly everything went EXACTLY right for a DC snowstorm and DC got a 37 degree rain or mix event. I don’t know what to say and frankly I don’t even know what DC needs to get snow anymore. Colder is the obvious answer but if a storm takes the perfect track colder would have suppressed it. If the amount of suppression it takes to get cold enough is so much so that it squashed any wave that’s a problem. And don’t bring up Dallas. They aren’t near the coast east of mountains. Totally different climate. If I had to guess, I'd say part of it is sea surface temperatures--if the Atlantic is warming, it would make it much more difficult to get cold and stay cold in the costal plain. Unfortunately since that's global warming-driven, there's not much we can do about that. But would a northern-stream dominant flow also have an impact? I.e., are systems required to dig more without drying out too much (which seems to have been happening with nearly every storm inside 72 hours), which makes any set up pretty precarious? Maybe it's grasping at straws, but that is something that (hopefully) doesn't stick around forever, and wouldn't necessarily imply that even moderate snow in the DC-Baltimore area is just shy of a lost cause...

Lower mid Atlantic, northern mid Atlantic, northeast, have done fine compared to climo. So somehow the sea surface temp is only hostile here? And our temp issues are not just a winter phenomenon.

Over the past 40 years there have been more storms than I can count when NW burbs get significant snow accumulation and DC gets nothing. Lack of elevation and marginal temps at work, and it only becomes more of a detriment as we get further along in the season Link to comment Share on other sites More sharing options...
