OceanStWx Posted December 8, 2023 Share Posted December 8, 2023 Just now, Typhoon Tip said: This is an important ( fascinating if your a nerd like me ) aspect above ( bold). If true, it's a part of my faster hemisphere hypothesis - which has been recently corroborated by ... https://www.nature.com/articles/s41558-023-01884-1#citeas ..Anyway, it's "possible" that what you're describing may be a emergence of error forcing that was not as prevalent during the 'growth spurt' era of modeling technology in the 1970s-2000. The idea being that we engineer tools that suffice the observations of our environment - which these tools may not be designed to account for a fast atmosphere sending along balloons that sample the "wrong" region of the troughs and ridges. That's really cool! Modeling isn't my strong suit at all, so I don't know how they handle this aspect. But if you pull up any upper air map to hand analyze, they are plotted as if they are over the launch site. However we get winds from GPS calculations, so we know where the balloon has been at all times. It is possible they use the lat/lon pair when ingesting it, I just don't know for sure.

That's an impressive shift for present modeling standards in the Global s ...not so sure about the NAM's bi-polar tendencies beyond 48 hours... However, it seems to be behaving this time given what's going on with the other guidance et al. I'll tell ya, another shift of that magnitude, SE, and we bring snow collapse and real totals contention into the Berks - Monads axis 1 Link to comment Share on other sites More sharing options...

Snow maps agree. Taking the under for my area but I'm hopeful that the further East development will increase the odds for some upslope in the aftermath.

OceanStWx Posted December 8, 2023 Share Posted December 8, 2023 5 minutes ago, CoastalWx said: 6z GFS pretty wild at BOS on BUFKIT The current NAM/GFS forecasts just have the core of the LLJ so low that it's not hard to mix some of it down. Now there are seasonal differences between the two storms, but the Nammy is currently a more impressive forecast than it had for Oct 2017 right before the event (like 12 hour lead time). Obviously there were still leaves near the coast then, but just the magnitude of wind. Link to comment Share on other sites More sharing options...

An hour or two of snow too me seems like the more likely scenario, though I could see something like 2-4'' for the ski areas. The dry air is rapidly building in on the backside.

I dunno but that could get good, no? The repetitious posts of warm December maps imply like it's some shock, as if it was unexpected, strong nino and all. Nothing you can really do but just let the warm crowd enjoy and soak it all until the expected change in January. 3 Link to comment Share on other sites More sharing options...

Typhoon Tip Posted December 8, 2023 Share Posted December 8, 2023 The meteorology of this thing is interesting enough for me. Sensibly? hey, if snows even an inch after the frontal axis slips passed any location that will be 60 not 4 hours prior, that's notable. The whole situation may yet adjust more SE, too, so that description above may need to changed. I think we're getting some morphology out of a data relay off the Pacific that we don't normal observe ( as much...) in recent modeling. Bit of a wild card there.

wxeyeNH Posted December 8, 2023 Share Posted December 8, 2023 Congrats PF. Nail biter yet again for me. Friends just arrived here from Boston and were amazed how sharp the snow on the ground line is. Still a winter wonderland but just climbing above 32F which is taking the snow off trees for the first time since the storm. Took the drone up this morning. Hills are white. 9 Link to comment Share on other sites More sharing options...

Not as pristine as on Tuesday and Wednesday, but still amazing for the 4th day after snowfall ended. 10 Link to comment Share on other sites More sharing options...
NW_of_GYX Posted December 8, 2023 Share Posted December 8, 2023 Opening day at Pleasant Mtn. Enjoying it today and tomorrow. I commented on the east shifts yesterday, but this is still looking like a big headache for CP Maine folks. We rip on NW winds and with trees loaded up with snow this could be bad power issues. CMP has crews from California in my area right now doing preemptive pruning. . 5 Link to comment Share on other sites More sharing options...

Latest info means maybe mid-30s gusts here. We've had only one event that brought gusts stronger than 40-45 since May 1998, a near-severe TS in June 2005 that had a 30-second spell of (probably) mid-50s - rain-mist filled with twigs and numerous large aspen broken down. 1 Link to comment Share on other sites More sharing options...
