My best guess right now is an additional 3-6" inches.

Let's see that pivot. There is some backfilling now as the dry slot makes it's further progression north. Going to see it fill in. Just a matter of how long it may take.

Here I'll post the rest. Lower Elevations Including the Coastal Plain: Ptype has mainly been a cold heavy rain through early this morning given warmer boundary layer...but Ptype was in the process of flipping to wet snow across parts of southwest MA and into portions of northern CT. This likely a result of the intense vertical motion and heavy QPF despite marginal thermal profiles. As the main coastal low rapidly intensifies and lifts northward of the eastern MA coast...thermal profiles will cool further and Ptype should flip to wet snow in most locations through mid to late afternoon. In fact some of the high resolution guidance intensifies it to nearly a 975 mb low east of the MA coastline. Temps will likely remain above freezing outside the most intense snowfall. However...this system is so strong with intense jet dynamics and a classic intensifying 700 mb closed low along with backbent mid level warm front. This may result in an area of heavy wet snow...but there is uncertainty where this may occur. Thinking is that areas of northeast MA may stand the best chance of getting impacted with this for at least a few hours. This could make for a few hours of very difficult travel this afternoon especially with the strong winds expected to develop. But this will also be competing with a mid level dryslot which makes things quite tricky. While uncertainty is higher than what we would like to see...opted to upgrade to a Winter Storm Warning for the rest of northeast MA for 3 to 8 inches of wet snow especially because it will be combined with a period of 45 to 65 mph wind gusts this afternoon. Things may get quite messy across this region during the afternoon given the wind and wet snow and travel may become quite difficult with power outages. We also upgraded portions of the lower elevations of southwest MA for 4 to 8 inches of wet snow including the Springfield metro areas. Meanwhile...thinking area in the 500 to 800 foot range end up with snowfall amounts on the order of 6 to 12+ inches of snow with power outage potential. Snow will continue this evening before winding down overnight. Even portions of the Cape/South coast may see a few inches of wet snow before everything winds down. 2) High Wind Potential: A powerful NNE low level jet will develop on the left side of a very strong 975 mb low pressure system off the MA coast. This will result in strong wind gusts developing...which should peak this afternoon. High Wind Warnings continue for the eastern MA coast...for a period of 45 to 65 mph wind gusts. The strongest of the wind gusts will be across eastern Essex county/Cape Ann given their exposure to a 70-75 850 MB NNE low level jet this afternoon and evening. Conditions may become quite difficult for travel especially with the wet snow and potential power outages. Further inland...wind gusts of 35 to 45 mph will still cause issues with pasty wet snow and lead to power outages.

This is a very important part of the morning now. That mega band is going to pivot and rotate, but how long does Northern CT dryslot?

5:30 AM

3" at home in Simsbury, per the wife.

NE CT from Kev to I-90 is going to get crushed.

I like 3-6" at Logan and more away from the harbor.

I think Kev flips in under an hour. Kev- check ur PMs

Moving east already now and trying for a pivot. Might dry slot briefly but not for long.

GIF is too big. I am not sure how to get it below 2 mb

Kevin will be snowing within the next hour. The warm air is collapsing southeast now. Can see it very clearly on dual pol.

If it does dryslot, it's not for very long. You see that band lift north with a slight lull, and then it quickly drops back south and even shows signs of intensifying. NWS Boston just posted on Twitter. They have upped snowfall totals for CT River Valley.

6z HRRR 10:1 weenie maps print out 20" at the Union/Sturbridge border.

Some of the modeling goes gung ho and rotates this band, reorienting in an east-west direction. With heavy snow me to you underneath.

Thanks, I think you do well. I think nearly all areas do. Dual-pol shows mixing pulling back SE.

Down to 32F now in Simsbury, while Tolland is at 38F. That's wild.

I had 1" of snow on the ground with heavy wet snow and massive flakes when I left home at 3 AM. 33F on weather station. Abruptly switched to rain once I arrived near 218 in Bloomfield. Very heavy rain all the way to Rocky Hill.

Down to 33.7f and still mixing mostly wet snow. I think it's a good sign overall need to get some sleep. Up for work in no time. Hoping to wake up to the beginning of some fun stuff.

You guys are quick

Well, guess what. That was 18z. 0z is this one. Even snowier. My bad.

That's the melting layer. Simply put, the further it grows outward, the further the mix line travels roughly. Weenies want it to contract. But again, a reminder: a final push of warm air was modeled tonight. Then it rapidly collapses.

Don't think it lasts. I'd love if it did. A lot of modeling showed a bit of a warmer push before low stacks overnight. Not sure if that continued in latest runs.

Just printed 12" here too. Demolished west of 91.
