It's Always Sunny Posted October 26, 2021 Share Posted October 26, 2021 Off topic question....I may have asked this before and forgot to take note of it (or check in on the person's response) but what is the general cause for NW trends for coastals? Beta drift or something else? Thanks in advance. Link to comment Share on other sites More sharing options...

I haven't read super recent literature on this, but a decade-plus ago it was undersampling of shortwave energy and underestimating latent heat release in the warm sector which provides a feedback to amplifying the trough. I suspect the data sampling issues aren't as bad as they used to be, but the latent heat problems would still persist to an extent given how most of our guidance obeys hydrostatic balance. 1 Link to comment Share on other sites More sharing options...

Makes sense. Have you noticed the NAM having less of a NW tug with coastals since it is non-hydrostatic? Tbh I don't look at the NAM as much as I should so I can't say whether or not that tendency is there. Link to comment Share on other sites More sharing options...
MJO812 Posted October 27, 2021 Share Posted October 27, 2021 LA Ninas are notorious for early starts to winter and then a warmup in the 2nd half. Let's hope we get blocking this winter. Link to comment Share on other sites More sharing options...

I don’t consider snowy December’s early. Growing up in NNJ, it seems we always had a good snow in the first half of December. Link to comment Share on other sites More sharing options...

Maybe it's precise location, but in my NNJ days only 1960 featured a snowfall that was bigger (way bigger) than moderate during the 1st half of December. 1966 had a 31-32° dump of 7" on 12/13 that was gone in 24 hours but that's probably #2 for 12/1-15 from when I became aware of snowfall size about 1954 until moving north in early 1973.

That’s like the weenies in the mid-Atlantic getting storms on 12/5 between 2002-2007 so if you were super young growing up during that period you thought it should always snow in early December there. I think 4 of those years had at least advisory snows? (2002, 2003, 2005, 2007...the latter two being weak events that didn’t produce much up here in New England) Link to comment Share on other sites More sharing options...

I really haven’t read too much into the solar aspects We're still temporally near the minimum of the cycle even though getting some active sunspots. I think we're still good even with the recent spike given the historically low background state of this cycle. Also, the low but ascending part of the cycle generally seems to do better than the descending part anyways (unless you're near the 11-year peak) Link to comment Share on other sites More sharing options...

There’s a huge Aleutian low where normally in La Niña we see a high/ridge there. The key in La Niña is to get the ridge poleward so it’s shooting up into AK/Bering Strait. 2 Link to comment Share on other sites More sharing options...

Nearby places had 8-10" in that 1957 storm - odd that I have no memory on it. (Though the 24" paste Bomb on 3/21-22/58 may have wiped the earlier snow from my mind. And/or the windy and cold February storm, 15-18", which I do recall.) Only 2-3" in that 1958 event. Link to comment Share on other sites More sharing options...
raindancewx Posted October 30, 2021 Share Posted October 30, 2021 It's interesting looking at the near term. Eyeballing it, the AO looks positive but the NAO is negative. We're in the weird La Nina transitional pattern now that happens in a lot of November. But even so, I'd expect that NAO/AO split to show up in the winter a couple times. For what it's worth, NDJ seems to oscillate in La Ninas from the SE or SW being hottest by how active the Atlantic hurricane season. These are the La Ninas since 1990 by ACE Index. Pretty obvious where the biggest impact is, but the West/Central heat has downwind impacts for the East too. Relatively inactive (<160). Highly active (>160) Link to comment Share on other sites More sharing options...
