Sunday the 18th ... storm idea/early thoughts...

Nothing to stress about here. Been like this for days. Snow growth looks good. 4-8” with lollies to 10” along 84. Enjoy.

I do think N of Pike W of Worcester Co. is going to be victimized by less than stellar rates and marginal snow growth.  Waking up and only seeing 2" otg is not going to shock me.

interesting little under-the-radar environmental aspect to this deal... 

we are getting some unadulterated bright sun pretty pervasively... and temps are responding.   DPs, however, remain very deeply depressed and given to the nascent quality of this air mass, ...probably that's at depth in the sounding.  So, it's kind of like one of those razor thin "fake" warmth layers you get in spring.

This is at the colder end of a spectrum of event-types that are common in spring ...where the surface belies the real potential lurking and dictated just off the deck.

At least for CT I'm not totally wowed by the snow growth. It's decent but I dunno. There's a bit of drying later in the event in the SGZ and even before that the best omega is a bit displaced. 

If I remember correctly Ryan, you weren’t completely wowed by the snowgrowth potentials back on December 9th either, and that turned out to be a pretty good event for a lot of the area...with very good snowgrowth.  This upcoming event has been reminding me of that one a lot.

Diane I think you may be ok. 

I could go either way. I won't be surprised if I get 6 inches of paste, but I also know I could be rain or white rain. I think that because this is happening at night, I may have a better chance of being snow...but with a southerly component to the wind, that never bodes well for my area

Are you concerned about some mixing anywhere along the CT coast, say Groton/New London area?

Bufkit soundings do show a major drop in snowgrowth but looked like maybe around 4z or so? I was concerned about this as well but I think that should happen after the majority of the heaviest snow already falls. Perhaps this prevents 7-8'' totals but I do like (on the NAM at least) how the strongest 700mb fronto juxtaposes well with the highest 700mb VV's.

Certainly within the margin of error, sure.

You can also see some dry air at the top of the DGZ.

That is not a wild snow growth look IMO. It's adequate but it wouldn't make me go crazy high.

wrf soundings look good.

Wouldn't be totally shocking inside good banding. The snow growth depths are very good. Though obviously the higher the QPF, the harder it is to go 20 to 1. But I wouldn't be completely shocked at double digit lollis inside some good bands where like 0.5-0.6 qpf falls. 

IDK why Ryan is worried about snow growth. His boxing day melt still affects him to this day.

The exact numbers are -12 to -18C i believe

I do know that the optimal temperatures are between -12C and -18C so for like purple contours you have 0, 5, 10 and then starting at 15 they become yellow contours. So is what you're saying each contour is the temperature you want intersecting that contour for optimal snow growth?

One big difference between the NAM/GFS is when the 850mb low develops and when we see a closed off circulation. Normally when forecasting amounts upwards of 8'' I would like to see development/closed contours much earlier, however, I think there are other processes which could overcome this such as really strong fronto.
