That’s not a classic confluence look (as mentioned by Heisy with it ‘trending’ towards it) but notice the tightly spaced isobar lines over New England/off the New England coast? That’s typically a sign of confluence.
In our classic mid Atlantic storms, you’d see those isobars stacked tight together basically running due east off the coast of New England.
It basically helps to lock in / reinforce cold air. It’s why our big MA events feature 50/50 lows that lock in the confluence.
Someone smarter than me can probably explain it better ha.
8 degrees at McHenry. At least the ski resorts have been able to make snow during this arctic blast. It’ll help with the mini warmup before the next reload.
Top of Wisp weather station - elevation is over 3100’ (weather station lists the wrong elevation)

Great night skiing conditions!
I loved reading the obs out there, thanks for sharing them (and katabatic, others too). Hoping for a good January/February out there with some memorable events. I’d love a repeat of last years MLK storm again this year.
