Man boston got screwgie in this, so close to much more, that first batch of mid level lift in the 600 mile band was oriented a hair to far south (which was pretty well modeled) and that lift fell apart at like 5z and there was just not much left 6-12z when it oriented N-S this was when areas further ne were to cash in .

That sw entering the base of the trough seemed to be the culprit and even mentioned in the box disco as to robbing forcing mechanisms along north side of trough (us) by the time it alligned more n-s the lift never got re-established sufficiently, ask GYX about that

Check out the death band totals from Mass to VA

Yeah that s/w at the base really screwed the pooch for getting more widespread warning totals. That was the s/w I had been worried about earlier in the day when discussing the early 12z model runs. Then the mesoband happened and it didn't matter for those who got into it, but for those who just missed it, it ended up mattering a lot since it cut off the moisture feed by mid to late evening. Originally there should have been another 6-8 hours of light to moderate snow which would add 3-6 inches.

 

The band probably made the lack of moisture inflow more apparent with a bit of subsidence just outside of it. In hindsight, you can see how the screwjie happened for areas northwest of it...but at the time, there was no rational way to really predict that outcome.

Blue Hill came in at 29-1

 

Extremely light, fluffy snow fell across the summit of Great Blue Hill totaling 12.1

inches with a liquid content of 0.42 inches of water. This ratio of roughly 29:1

represents very dry snow not normally seen in our region. The bulk of the snow that fell

overnight occurred during temperatures that ranged from 11 to 5 degrees.

 

That is awesome...

ok on Modis Lake Huron what is this, pack ice?

 

Yes that is ice forming, on Georgian Bay, the shallower eastern section of Lake Huron. This happens fairly regularly towards the end of colder winters. Large ice formations wash up on the southeast shoreline at Wasaga Beach which is a ten-mile stretch of sand. You can also see Lake Simcoe in the lower right of that shot, it almost always freezes for most of Jan-Mar although strong winds can temporarily disrupt the ice cover. There are also signs of some ice formation in eastern Lake Ontario extending out from shorelines. In most winters, only the shallow bays around the Prince Edward county peninsula freeze but in Feb 1934 the entire lake froze shore to shore for several weeks. There was also extensive ice cover in Feb 1979.

 

Returning to Lake Huron, widespread ice cover in the main portion of the lake has been rare in recent winters but can form over large sections in cold winters, more likely to show up in February as that is quite a large, deep lake and is still at 2-3 C. Georgian Bay is almost self-contained with just narrow and shallow channels connecting to the main part of the lake, so it can freeze faster.

The shadow indicates significant height. I would love to see a ground shot.
