I would like to see the lift smack into the DGZ when the column is cool enough. You can see prior to the flip, there is good lift in the DGZ which likely helps to top down cool. But as the low intensifies, the lift lowers a bit. Maybe it bombs and contracts everything near the center. That would help. Link to comment Share on other sites More sharing options...

That storm had a much better airmass. Hate to see it. Best chance for BOS area I think is evening when that stinger rotates through....hopefully it is still very intense. If it is, they could see 2-3 hours of pretty good stuff. Link to comment Share on other sites More sharing options...

I was outside dealing with Xmas lights during lunch. it was actually quite toasty in the sun. then I tried to think of a time it was this warm the day before a snowstorm.

Anyway, enjoy whatever happens. Our fate’s definitely sealed for a cold nasty rain event here. If only this was 5-8 degrees colder. Link to comment Share on other sites More sharing options...

Boston Weather Service seems to think the track is staying mostly off shore and not over the Cape and Islands as some but not all the models have. So that may be where the difference in thinking is. Which may translate to the potential heavier amounts shown. Link to comment Share on other sites More sharing options...

Kaner587 Posted December 4, 2020 Share Posted December 4, 2020 Been tracking this bad boy focused in Vermont ski areas (notably okemo) and wondering your guys thoughts on the western edge. From what I’m seeing after the worst of the East trend has ended it does seem like there may be some decent lift especially early aftn into evening tomorrow but my concern is how the models are handling the western fringe. There is definitely going to be a sharp cutoff on the NW side which right now seems to be worst between southeast Vermont and central mass (going from 0.75 to nearly 2in qpf on the euro). My concern is that precip might be overdone on the western fringe however in looking for some eveidencr of this, the FGEN maps from for example the RGEM it would support the model output of 0.5-0.75 qpf for most of southern/east central Vermont so maybe my concerns are unwarranted. Thoughts? Link to comment Share on other sites More sharing options...
mahk_webstah Posted December 4, 2020 Share Posted December 4, 2020 helluva forecast to have to make for the first storm, with all of the factors up here...ratios, rates, etc. But the recent models are all 12+ go 8-15? probably more like 6-12. Or live large at 1-2'? Probably only do that overnight if the outputs continue to show ~2"qpf. Link to comment Share on other sites More sharing options...
STILL N OF PIKE Posted December 4, 2020 Share Posted December 4, 2020 Euro hit ASH area much harder than GFS Flips us by noon I spy a jack from Ashburnham to Miller state park on that pivotal map Thru Sunday eve with tons of spots doing very well With similar amounts up to Phin Link to comment Share on other sites More sharing options...
wxsniss Posted December 4, 2020 Share Posted December 4, 2020 Boston metro (including metrowest) will be fun to watch ~18z-0z Saturday when 850/925 crash <0C, great rates, but surface is still 37C. I think at the very least, a tight gradient of sloppy coating-2" at coast to 2-4" out by 128. But even an extra 1-2 hours under the best rates would add 1-2", and that's definitely realistic.

That low level lift is no bueno for snow, it's either going to be precip rates too light for changeover or heavily rimed snow that has trouble stacking up.

What side of the hill / mountain are you on? Top of the hill or bottom? I won't get the highest, being on the north side and at the bottom but it should be interesting. I'm hoping it's not 8 inches of concrete though... Link to comment Share on other sites More sharing options...

Here's the 30h height field, plus 30 and 36 hour RH fields....it's moving E between 30 and 36h...so metrowest may get into the good stuff for a time....but you can def see that it's prob dryslotted out to like rt 128 at 18z tomorrow.

I thought the Euro looked overall better on the bent back front aloft than the GFS. GFS brings it awfully far inland (which also explains the crap clown map).

Yeah, whatever layer that feature is most discernible. Sometimes have to increase the height contour density. Link to comment Share on other sites More sharing options...
