Jan 12 Overrunning Snow/Ice disco


Damage In Tolland

Recommended Posts

I think you'll do okay, perhaps 2-4". Due to orographics, I think this may be a nice little advisory level event for these parts as the meso models are picking up on this signal.

 

While it may be a little overdone, the 4km NAM shows this potential well.

 

I really like SVT and your area to MPM for the jackpot.

 

If I were MPM I'd be pretty excited for at least a nice snowy day.

 

I'm liking what I'm seeing up here too, with a slight nod to the southern orographics of Southern VT on a SW flow into that higher terrain and the northern Berkshires for jackpot.  But I'm thinking we could do 3"+ advisory amounts up here...maybe even low end warning but like only at the very peaks and down the Spine to Greylock in Mass.

Thats a great tip, see that's an awesome post and helps me in the future....better than just PF never learns it magically snows further NW every storm haha.

I didn't go to school for met, so the background equations and mid-level stuff to me is more vague, and I need to visually see it...if I see -15 to -20 micro bars stalling over SVT to CNH, I'm not as excited, even if the H7 track looks somewhat favorable.

But knowing why that happens is great to look for in future systems.

This storm though it's been pretty easy to spot the chance for an advisory snowfall vs just a D-2".

Don't forget everything is tilted in the atmosphere too. So that lift at 700mb exists further up like Will said as you move NW. I feel like the 600 and 500 layers get overlooked especially in storms that aren't particularly cold. The cape had an event in 2013 where the lift was near 500 and they got smoked with a quick 3-6".

Yeah, maybe 8" up at Stratton and Mt. Snow? The plot I posted puts out nearly 10" for there, but likely a little overdone.

I will say if the size of the dendrites coming out of the sky right now is any indication, tomorrow could get sneaky good.  This is pure massive 30:1 ratio dendrites falling right now...its just -SN to flurries (probably 2-3sm vis at the mountain, and 5-7sm down in town), but the flakes are like things you'd think would come out of a down pillow.

Yeah thats solid Advisory snow for you now...definitely got rid of that CAD mid-level dry air pocket that was around yesterday on the models.

 

Pretty hideous for 90% of SNE.

 

Is there a general  threshold for advisory snow?  I know they tend to issue those much more subjectively than they do warnings.

Most spots its 3" or greater.

 

Edit I just saw Nittany posted 4".... I thought it was a 3" average or higher?  If so, then widespread 4" maybe harder to get to.

 

Edit number 2... so its 3" in Mass/CT/RI... but 4" in NH.

Thanks.  I doubt we'll see much of that down here.  Perhaps a gratuitous one for western Hampshire/Franklin/northern ORH.

I'm going 3-5" for most of the Berkshires tomorrow, with a spot 6" possible at 2K+ from Peru on up toward Woodford, Mt. Snow, and Stratton. I expect a bit less south of the Pike with 2-3" for that area in South Berkshire County as some freezing rain and sleet will likely mix in. Thanks to SW flow near the surface, I expect the highest totals to be on the west slope and Taconics. 

Seems very palusible

Euro is pretty stubborn with the interior cold at the sfc...N of pike may pull off 2-3"...more confident Rt 2 north.

Yeah I felt even I might end up net gain on the euro with a pretty big cold push much earlier vs other guidance and a less robust push north of the warming aloft.

Updated BOX forecast introduces IP/ZR into GC.

 

Tonight: Mostly cloudy. A chance of snow after midnight. Not as cool. Near steady temperature in the lower 20s. Southwest winds 5 to 10 mph. Chance of snow 50 percent.

Monday: Snow and sleet in the morning...then snow...sleet and freezing rain in the afternoon. Snow and sleet accumulation of 1 to 3 inches. Highs around 30. West winds around 5 mph. Chance of precipitation near 100 percent.

 

17.0/5

I'm confused. Will says a couple of inches n of the pike, Scooter says toasty to NH border....What gives?

 

At 850 it's cool enough, but seems like there is a warm layer at 925. I think near the NH border is still good for maybe 1-2 or so..the Pike area could be more ZR or IP perhaps. 925mb is +2 near the pike. I think the question is more rt 2 and NH border.

Unbelievable. I can't even get a simple 1-3" event.

 

Well I just said you might..lol. I can't see a sounding..but just experience tells me 925 may ruin the party for some. If it's off by a degree or the layer is thin..then all bets are off. We'll see how the other models look at 18z.
