Sleet at least adds up and makes the snowpack last, we want to avoid rain though (NAM shows a bit at the tail end for southern parts of the city).
Just need the NAM 30-40 miles south and I honestly don't care if we flip to sleet a bit earlier than modeled.
Relatively speaking (to what I was responding to). For me personally, 6 inches would be a success and anything more gravy.
Less than 6 would hurt a bit
GFS is always too progressive overall, kills off primaries too quickly, and sucks at thermal profiles that mesoscale models excel at. I'd be cautious with it when it's so different than other models.
Sleet has some serious staying power though, it would preserve the snowmaking for a while (though in this case it's crazy cold afterwards so it wouldn't matter).
The NAM is beautiful. I'd much rather have the thermals trend favorably and then figure out the precipitation distribution and intensity than the other way around.
Probably a touch warmer than 6Z aloft as sleet moves in just a tiny bit earlier. Still a good run, with 7+ inches (at 10 to 1) accumulated by the time sleet moves in.
On top of the synoptic impacts, verbatim this would yield a significant upslope event for the northern Green mountains.
Still in fantasy range, but definitely fun to look at.
First part of the storm should feature some good ratios. About -10C on all levels, temps in the DGZ region is ideal (-12 to 18 Celsius is what you want to see) and winds aren't overly strong.
The run-to-run changes out west (even in the short) on all models is wild, and really highlights the complexity of the storm. Oddly enough, the surface depictions are a lot more consistent.
Pretty much. After that it's a timing thing, if the phase out west comes together quickly, heights will quickly rise.
Do many variables here, it's simultaneously frustrating and fascinating to track.
Since what we're looking for out west seems to allude most people, I'll at least mention that confluence is notably better in the east at hour 36 than last run (heights are lower).
The V-day sleetfest (still my favorite sleet storm ever) had temps in the teens and low 20s and a storng high anchored upstate. A mid level warmth push can happen regardless of the surface depiction, happens here all the time.
