    Some of that is from orographic enhancement over the mts...so you'll see a bit of a decrease in the intensity but it should hold together. 

    Last I checked, the Froude numbers were 1.5-2.0 so the flow perpendicular to the ridges was not blocked at all and easily cresting the tops. You have to be subcritical blocked for the mountains to rob all the moisture.

    That was January 2016, just a few days before the blizzard.  I had to leave my van and seek refuge in a friends house until someone with a jeep could pick up me and my kids.  And even the jeep got into a small fender bender on the way home.  That night convinced me to get snow tires (Blizzaks) on my minivan for the winter.  

    +1. Best snow tires out there. They make driving in the snow and ice a revelation.

    High ratios there, cool

    Maybe. Colder does not always equal high ratios. When it gets too cold, columns and needles become the predominant flake type.  At onset, it’ll likely be around 10°F with around a 0°F dew point. And with a column as cold as it is with limited moisture transport, I’d guess those flake types will predominate. 

    For example, last week in VT, it was snowing just on either side of 0°F with 30 dBZ returns and, for the first 6 hours of the storm, the snow ratios were 9:1. Only after 6+ hours of a southerly 70kt jetstreak above 800mb did enough moisture transport in from the south to change the flake type. It was 0°F at the surface but jumped 22°F in the snow growth zone and ratios jumped to 15:1. This little impulse is just not that dynamic.

    I have GOT to experience lake effect some day.  That's definitely on the bucket list.

    +1.  I've experienced it twice this winter in upstate NY a couple of times I've driven instead of flying to VT.  First time(s) for me.  They are remarkable and worth the trip.

    My snow is so wet and dense that my electric snowblower quickly choked on it.  Had to just use the shovel.

    They didn't do our streets and it's like 1-2" of slush.  Going to be a sheet of ice tomorrow morning.

    Mine too. Pretty dense. I’ll try to get a water content later. 

  6. It was a good day. 16.9” snowfall total in Charlotte, VT. I can’t say I’ve ever seen 40 dBZ returns with subzero temps (-6°F) before. It was very cool to see the raging SSW WAA above 800mb and NNE cold air draining down the Champlain Valley at 925mb.  Very cool storm.
