Over to all snow here. down to 34f (!)

I think you're right

Top 5 spring storm for scoot if that day after tomorrow solution verified.

Imagine if this backs in 1/8sm, 70mph winds from Massachusetts Bay

Good god. 3k NAM. Hello weymo

Mike Masco on Twitter. Good look at this one.

They'll never find them now

1015 PM Update... * High Impact/Major Winter Storm with 1-2 feet of heavy wet snow & power outages into Tue for northern ORH Hills/Berks * Rain overnight in most lower elevations which will eventually transition to some snow Tue but amounts/impacts uncertain We have high confidence that a serious/major winter storm will impact the northern Worcester Hills/Berks above 1000 feet in elevation overnight into Tue. Firehose of rich moisture combined with tremendous forcing/dynamics and thermal profiles are all supportive of 1 to 2 feet of heavy wet snow & power outages through Tuesday. This will be a very serious storm for these locations. Forecast confidence is significantly less to the south of the MA Turnpike and all lower elevations. While some wet snow has been mixed in with rain at times across the lower elevations of the interior...ESE low level flow around 925 mb should result in some warming in that layer overnight. So expect mainly rain in this region through daybreak. This 925 mb warm layer begins to erode Tue am and especially by afternoon. How quickly this occurs and where exactly the dryslot and intense frontogenesis sets up will be crucial if significant accumulations occur in the lower elevations. This is quite complex too considering very marginal boundary layer temps. Given the rapidly intensifying low pressure system getting pulled back towards the coast along with an intensifying closed 700 mb low will need to be watched. If there was an area we were most concerned about in the lower elevations for significant wet snow accumulations...its portions of northeast MA especially just inland from the coast. We are still evaluating the latest model data.

Lamont just issues tractor-trailer bans. If you're a mobile weenie, get off the roads.

Trying to flip to snow. LOL. Doug flutie, back to pass!

Oh lord. Giant white flakes falling now. Hold me. 35/34.

Cycle between dual Pol loop and Reflectivity. You will get a good visual of bright banding. Reflectivity will mimic the melting layer on the beam

Seeing that rain snow line retreat south a bit on dual Pol.

There is an mping report of snow near *new haven*

I take it back. There is wet snow mixed in with this rain. Very, very wet stuff though. 36F

Just rain right now

Eversource is saying it's preparing for 130k without power in CT.

36/35. A bit cooler than I expected at this point. Bed soon for me. Early into work tomorrow.

Same here in CT. But it doesn't make it very far.

37/36 Simsbury

39/36 with rain in Simsbury.

The 18z NAM 7h vertical velocity. Check out the comma head structure that goes up 91 in CT.

Here is the 18z RGEM 7h vertical velocity. Pretty nice banding signal here.

I think ORH on east has true red flags south of MA border. Concerned with the extent of that dryslot. Would be horrific combination of marginal boundary layer, and poor snow growth rates. Northwest Connecticut to the Berkshires has been targeted as sweet spot for days. The real enigma has been valleys, and Eastern New England. Further North and West you are, that dryslot and warm air is out of the picture. Looks great for Rt. 2 higher elevations no matter what. The real question is Eastern MA, valleys. Those are absolute wildcards. It's not like the temperatures aloft are super warm. It's very marginal there too. If we can overcome that with rates; look out. A weenie's dream = waking up tomorrow to isothermal man snow bomb. I have also noticed pretty impressive 7h look for CT on the backside of this thing. Considering the fact cold air is driving south, and the storm is stalling offshore, that could mean a nice finish for many in the interior of Southern New England. It's important to note the wild spread in solutions still at this close range. If modeling is struggling this much, means we really have some uncertainty on the table. Surface temperatures need to be watched like a hawk this evening.
