We have our first major snow of the season for the east as a low pressure rides along the stalled front that moves through tonight.
While we’re still waiting for our first major snow, this will have to do to get us through Christmas week (although there are some other storms to come before Christmas).
I’m still a little concerned for mixing at Bromley, though it looks more likely at Jiminy Peak. I chatted with Bill earlier today about the deformation zone of the storm, which typically showcases some of the strongest bands of precipitation in the system. Because there’s an influx of air into the system, mostly from the south or east, we tend to get precipitation type issues in this zone. That’s why we’re seeing the sleet/freezing rain become more apparent. High confidence in 3-6″ for Bromley, easily 6-8″ if there’s no mixing.

Cranmore will be the winner (if Bromley mixes) as there’s no mixing concerns and ratios will be far more favorable the farther north you go. Actually Cranmore isn’t far from the 15:1 ratio line. With ~.70″ of liquid falling in this system, and on the higher end of the snowfall ratios, we’ll probably closer see closer to 8″ at Cranmore.
Back to Jiminy Peak, you’ll notice in the snow to liquid graphic that we’re not seeing it much below the VT/MA state line. Therefore I’m anticipating more sleet and freezing rain for Jiminy. On top of a quick 2-4″, we’ll see some substantial sleet and then some freezing rain to top it off.
