NAM is more amped at 12z....but still fighting the dry air. If we're able to overcome the low level dry air then there could be several inches of fluff because the sounding have the snow growth zone like 200-250mb deep....that's a massive DGZ.
I'd def keep an eye on Friday south of pike...I'm prob toast up here for more than a feather dusting but south coast peeps could easily get a few inches with a small bump north.
I don’t think a big dog is really on the table, but you could envision maybe something a little higher than an advisory event only south of the pike. If we get more NAM-esque trends in the future, you could see a path to a healthy warning event.
Yeah but it was more because of significantly stronger dynamics rounding the trailing PV lobe really helping to pump up heights downstream and also keep the sfc baroclinic zone a bit closer
Light snow falling with a “chalky coating” as Tip mentioned earlier. It is covering the glaze of ice which covered the snowfall from earlier this morning.
At least it will look like winter for this colder stretch over the next week.
High here was 28.8F....dropped back about a degree to 27.6F now. Everything glazed though hearing a few pingers in the past 15 min, so starting to cool aloft or at least maybe saturate the DGZ again.
Pretty much all guidance has that high now...it's just a question of whether it presses down enough at the same time we're getting that low ejecting from the MS and TN valleys. I currently don't expect much of anything in SNE right now out of that setup, but it is something to keep an eye on. NNE could easily get out of the "torch period" unscathed if things break right.
Yeah I thought it would be more sleety than ZR given how marginal the warm layer is, but we have a solid glaze on everything...pretty sure at least 0.1" already. But it's possible that the drying aloft in the mid-levels (esp in the DGZ) helped it go to ZR quicker.
EPS def more robust than 00z which were basically a clean whiff. 12z gets much of CT/RI and SE MA into that 1-2" range. With maybe one more little push, there could be some advisory type snows.
Yeah we were even discussing how far west the ridge and trough axis was for the storm today and thinking there was a good chance it would come NW which it did. This one doesn't have that look. This one is all about separating the two broken PV pieces and that trend hasn't been favorable the last few days.
Maybe an inch or two for S CT. Improvement over 00z, but still not enough to entertain anything significant. Ceiling for this is probably an advisory event at this point.
Yeah you'd think....we get those types of systems on a semi-regular basis.
GGEM trying to do it too, but it's a little warmer....more of a ZR interior threat (snow for NNE though)
Getting the first sign that it's warming aloft since we're starting to get larger aggregates mixed in with the smaller hooked dendrites. Really pounding right now though...this is 1" per hour stuff.
GFS actually has a snow/ice threat for next Wednesday...sneaky high moves in and prevents everything from torching. That idea has been showing up off and on different guidance actually, so it bears watching.
