It's not pretty, but it's the way it'll have to be. The models have pretty much reached a consensus on WEST. Everybody has low pressure now tracking over New England, with 850mb temperatures rising above freezing for at least some time Thursday Night.

The interesting thing now is that the contributer to this shift, namely a stronger Atlantic ridge, means that the cold front crossing the region on Wednesday Night will stall further north than previously expected. As a result, 1) It will obviously be warmer in the mid levels and 2) Precipitation will continue through the day Thursday versus it taking a 12 hour break before the coastal low.

Why I italicized "in the mid levels" is because colder air will continue to seep southward at the surface, and will locked in place by a decent high pressure area in Quebec.

The result is ICE! Thursday will feature a wintry mix of freezing rain, sleet, and snow throughout the day. Timing still needs to be worked out (as can be seen by the fact that changes have been made to the Thu-Fri forecast about once every 6 hours). Freezing rain will increase in intensity through Thursday Night as the coastal storm approaches, then may switch to sleet and then to snow on the backside of the storm Friday. The Euro is wicked west, so under that solution, we would still likely go over to rain, which would limit icing. There is a LOT that can go wrong still.

Accumulations:
Right now snow accumulation looks minimal (likely under 4 inches). However, ice accretion could reach an inch!

--- Snowday Outlook ---
Ice obviously complicates things. With the front stalling further north and precipitation continuing through the day Thursday, this reopens the potential for a cancellation, maybe an early dismissal considering timing. After heavy icing / snow Friday has decent delay / cancellation potential. A LOT can still go wrong though.

Changes have been occuring with every single model run, so this is by no means set in stone.
