MesoscaleBanding Posted January 27, 2023 Share Posted January 27, 2023 (edited) Multiple waves...can separate later if necessary. Here's the latest GFS & Canadian: Edited January 31, 2023 by MesoscaleBanding 3 2 Link to comment Share on other sites More sharing options...
Grace Posted January 27, 2023 Share Posted January 27, 2023 Trends on 0z & even more so on 6z EPS ensembles: 1. 3 waves with a big increase in precip shield & amounts. 2. There's hardly any separation in the waves...especially the 2nd & 3rd wave. Monday through Friday of next week was like a continuous Winter weather event for some locations. 3. The best chances for snow look like North of the Ohio River, while south of that had very concerning icing ending in snow on last wave. **The biggest take away was it went from 2 lighter events & one major to 3 significant winter QPF events on several ensembles. 4 1 1 Link to comment Share on other sites More sharing options...
cperry29 Posted January 27, 2023 Share Posted January 27, 2023 Couple screenshots from overnight runs. Icing more prominent on the CMC. Link to comment Share on other sites More sharing options...
Admin BuckeyeGal Posted January 27, 2023 Admin Share Posted January 27, 2023 I keep getting a bunch of "When's our next snow day?" questions at school. I just answer, "Yes." LOL. I really think next week has potential for those of us that missed the mid-week storm. And I also think the snow-starved NE corridor may get theirs, too, with one (or all) of these waves. Shall see. Thanks for this thread, @MesoscaleBanding! 1 1 Link to comment Share on other sites More sharing options...
Grace Posted January 27, 2023 Share Posted January 27, 2023 12z RGEM is almost identical to 0z GEM at that point so probably going to be a similar outcome with first wave. 12z RGEM is a little colder at that point though: Link to comment Share on other sites More sharing options...

JayPSU Posted January 27, 2023 Share Posted January 27, 2023 Not to be a Debby Downer, but I don't see much to get excited about for the foreseeable future. 😥 At least, not in my neck of the woods. Link to comment Share on other sites More sharing options...

cperry29 Posted January 27, 2023 Share Posted January 27, 2023 Icon developing a wave on Wednesday. This is hard to keep track of. So many varying waves. 1 Link to comment Share on other sites More sharing options...

Models always seem to struggle mightily with these types of situations (multiple, relatively weak impulses riding along a boundary) in the mid-range. Probably need to get the Sunday system out of the picture before modeling has a decent clue. 1 1 Link to comment Share on other sites More sharing options...

If did make a brief appearance for that cold outbreak in December, otherwise, noon existent. There's a bunch of relatively low amplitude shortwaves rotating around said vortex, and from high latitudes. Remains to be seen if any can dig, and dig in a timely manner with the ejecting SW trof. It very well could be a final shortwave rotating through that digs enough, but that might also kick the vortex wear east, towards Iceland (+NAO) Split flow, weatherman's woe. 1 1 Link to comment Share on other sites More sharing options...
