  1. Jeez I wake up to like 3 pages of global warming discussion....lol. Model guidance has become more confident in widespread light snows. Someone is prob going to get lucky with a 4”+ lolli too given the nice soundings. It’ll just be a matter of where some LL convergence sets up the strongest and for longest period of time. Good nowcast event at least...these aren’t easy even at 6-8 hours lead time.
  2. You’re trying to find where the best low level convergence is because that is the primary forcing mechanism. Most guidance has been pretty consistent showing it somewhere between Portland ME area down to RI. The “natural” IVT looks like it wants to go over central/eastern SNE but S ME is always in the game because of the natural shape of the coast there which sort of promotes an IVT.
  3. Last week was less favorable. Moisture was really lacking aloft which is not the case this time. Most people will prob miss out in this but I do think it’s going to set up somewhere.
  4. 00z NAM back with the strong IVT for central/eastern areas of SNE.
  5. Not sure...but I figured after the holidays you’d be relaxed and may accept your fate of a record snowless winter in Tolland.
  6. Just log off and return after New Years all refreshed.
  7. Yeah and it's also possible the downstream ridging is overdone (or the extent of the western PNA trough)....I know I don't have to tell you that even if you displace that eastern ridge by a couple hundred miles to the south, we'd probably be quite cold as the northern edge of the positive 500mb height anomalies are quite cold underneath...that arctic airmass will be sloped of course.
  8. The extreme -PNA is really crushing the east with warmth in the extended. We can usually deal with a -PNA at this latitude, but not when there entire longwave trough is digging down into Baja. Like, here's the EPS at D15....you can see the AK ridge is totally restored...that is actually quite a stout -EPO, but look at how insane that -PNA is.
  9. Last year's grinch storm was an all timer. Prob 95% of grinch storms couldn't melt off 10"+ of pack in 8 hours like that one did....we had grinch storms in 2007 and 2008 which both failed to melt the pack. Last year's was like the Arnold Schwarzenegger of grinch storms.
  10. Euro was the most paltry out of all guidance down here. It is still showing that finger of snowfall from IVT though S RI up through central MA and S NH.
  11. 12z guidance has actually been pretty consistent with the exception of the NAM going nuts on the IVT....most other guidance is pretty much in agreement on 1-2" for a larger chunk of the region. There will likely be some areas of enhanced rates but you just don't know where they will be.
  12. Yeah if we assume the model is handling the polar domains fairly well, I'm figuring we end up decently colder than it shows at least up in the northern latitudes. It's really hard to have a ridge in AK and some ridging in greenland and end up torching....I'm not even sure how that happens at all outside of a temporary cutter or something.
  13. Oh for sure...if it actually verified...someone would prob get 10-12" fluff bomb from that look. The problem as we've been saying, this might set up 200 miles away too.
  14. The ingredients are there for a good one...we have deep moisture....not dry above like 800mb, lol. Extremely unstable lapse rates occur too. You just need the LL convergence/lift.
  15. Soundings become extremely unstable. I mean, this is classic heavy snow sounding from an IVT....I do think there's a decent chance something will set up, but we just don't know where yet.
  16. Yeah this is really it....years ago you only had basic QPF maps and had to use experience to interpret snowfall based on thicknesses/mid-level temps, etc.....now you have a trillion weenie snow maps (many of which are awful...in both directions) that every person has access to and it can muddy the discourse quite a bit....esp beyond D5.
  17. All guidance is rebuilding the EPO ridge pretty clearly around 12/20....we'll see if that date gets pushed back at all but if it doesn't, I'd expect plenty of winter wx chances in late Dec and into Jan.
  18. If anything, there is actually an inverse correlation for the winter with Sept/Oct. The warmest Sept/Oct tend to have colder/snowier winters. You don't want November warm though (which it wasn't this year). Just checking Boston really quick....their top 5 warmest Sep/Oct combos coming into this year was 2017, 1971, 2007, 1947, and 1961 (with 1983 close behind).
  19. Massive torch incoming for about a week or so starting this weekend...well maybe a brief break with FROPA on Sunday but then it torches for much of next week. EPO ridge rebuilds toward 12/18-20 but there will be a lag on our sensible wx.
  20. Euro has about 1-2” for eastern half of SNE and more up into Maine.
  21. Yeah and I think we’re out of time...unless the NAM was a headfake and other guidance comes in beefed up. Best hope for more than 3” is prob someone getting lucky under IVT.
  22. LOL...doesn’t need to when there’s a trough tickling Cabo San Lucas. Storms through BUF or through Chicago...same difference for us.
