I think storm 1 seems to be locking in a some sort of a flip to snow before ending for ORH on north and maybe down to the hills of nw CT and maybe nrn CT. Maybe a quick coating to an inch for ORH?

Yeah that sounds reasonable to me.

If the storm was bombing out like the 12z NAM from yesterday I think we could all see something... now I see a few wet snow flakes an maybe a slushy accumulation up in the hills of ORH county and God's Country.

We'll have to see if the NAM is on to something. SREFs sort of have this too as an additional burst of QPF. That might enhance things a bit?

Boy this weekend tho....lol.

I know... jesus.

I don't know what to make of the NAM and SREF with that second burst. I'd like to see a strong mid level low close off but that doesn't seem to be happening. I wonder what the mechanism is for the trailing burst... I guess the sharpening 500mb vort max provides enough DCVA and there's enough lingering mid level frontogenesis to give us a burst?

Yeah the low is sort of elongated wsw-ene. I think that strong s/w rounding the base of the trough acts to do just what you described.

Yeah it may be enough but these never really pan out as we want. If you're closing a sick 850/700 low then you can do it but in a situation like this it's never easy.

Anyway I'm sort of over the Thursday event lol... on to Saturday!

Yeah Mt Socks could pull out an inch or two Thursday

3-6"....I'm at 1300'. I probably wouldn't forecast more than 2-4" for the campus at this point given the warmer runs like the 18z GFS and 0z UKIE, but I like the hints of a CCB forming. Timing is absolutely perfect with the heaviest precipitation reaching us in the evening hours. 66 hour frame on the 6z GFS shows .5" QPF over the Berkshires extending towards the Monadnocks. Would be a monster hit here.

Back to bed...

The problem is it's not a CCB. If there was I'd agree with you.

The mid level lows don't close off and we're left with a tongue of frontogenesis and some QG forcing as the shortwave slides through.

I know it's not technically a CCB since we don't have the closed H7 and H85 lows, but it still seems as if the models are trending towards lingering more QPF behind the main storm, which starts out like a SWFE. The 6z GFS really blasts us Thursday night with that .5" contour over Western MA, and it looks as if little precipitation is wasted as rain since it is mostly a nighttime storm with the heaviest QPF behind the low. Overall, I'm liking the chances.

If you got 6" in the valleys from the weekend storm it would produce significant damage

I think even a couple inches of snow like 2-3 would do some damage. I remember Lundberg saying 2 inches in UNV 7 or 8 yrs ago caused all kinds of tree damage.

Luckily the winds today will blow many of the leaves down and Friday also looks windy. Most of Interior CT is past peak now

Yeah I just posted that a couple days ago.

2" did tree damage that was relatively widepread throughout State College

And no... most of interior CT is at peak right now.
