Jan 20/21 Snow Threat

So unimpressive.

1-3" north of the Pike.

2-4" south of the Pike.

Next.

But seriously, that SW is so pathetic as modeled.

Next? In this freaking winter? You're joking right?

I've come to the realization that I will never see a sub 990 low near the cape for 10 years

..

Mmmmmmmmm Brady in AFCCG Mmmmmmmmmm

Yeah the trend so far at 00z is to make the s/w less impressive...as we always say, these often bump north at the last second, but that s/w is being sampled for the first time on land, so this might end up more sheared out.

So we be on the northern end looking for the weenie band and ptype issues should be absent from just about all of our region.

Barring the EURO, I'm ready to back off to 2-4"

Euro is a tick south of 12z...but not much...about 0.30" for the ORH-BOS region...kind of like the NAM. Jackpot is S CT with maybe 0.40"...qpf isn't overly high anywhere. But that is going to happen if it gets a bit more sheared as dynamics will be less.

Still a pretty decent event though as ratios should be well above 10 to 1 with good snow growth shown on most guidance plus that signal for a weenie band on the northern edge of the decent qpf.

If it ticks a lick back north, that will probably be really nice for a more enhanced fronto band.

2-4"\3-5" fluff job

Yea, I may not be in a bad zone for that, assuming current trend is done.

Yeah...isn't there usually a weenie band at the northern edge of precip on these. Usually I'm modeled to getting .2" or .3"+ better than say MHT, but they end up with the same if not more SF than me because of the northern weenie band.

I'd take the current 2-5" as modeled and run though.

Both the GFS and NAM have the best region of ML frontogensis over SNE and a lowered area of EPV...so that suggests that a weenie band will develop on the north side of this...that isn't always the case in these events, but its definitely there in this one.

Even though its south with the qpf...the best region of ML fronto on the GFS goes like right over Ray and back to my area and into NW CT...so its something to watch. Its possible Ray is ripping SN+ in that setup while people to the south with similar echoes are baking soda at 1/2 SM SN with worse ratios.

We can't really say too much yet on this though, it could trend more sheared out or it could trend stronger.

These weenie bands on the north edge are tough to predict, but all indications are that there will be one as long as guidance doesn't drastically change. They are tough to predict where they will hit, but in places that do that get them, they usually can outscore predicted/modeled snowfall by a factor of 2 or so...in extreme cases by 3 or 4...but that doesn't look like a case this time.

This has the possibility of being our best event since October (not counting the back-to-back events GC and PF got last Thursday-Friday), so I think we should all be thrilled by the qpf/ratios that are modeled at this point. Good luck to all--I hope to read exciting reports tonight/Saturday.

Have a safe trip mike!!!

This looks like a solid 4-8" from a BOS to Springfield, MA line southward, probably more towards the 7-8" mark near Taunton, MA, 3-5" on the Cape and Islands and closer to 2-4" near Springfield and NW MA, with SCT and RI getting in on the 3-6" mark. Again down here in SC is rough this time of year knowing that I'm missing out on snow constantly, but I'm going to be in a nicer and warmer place as well as watch the PATS/Ravens game from the confines of my dorm room and not with my family which stinks. Anyways hope everyone here had a great 2011, I had a rocky one, but nonetheless my first year in the USAF has been a busy one.
