It was still too brief a phase 8 last January to significantly weaken the Pacific Jet. So the kicker shortwaves coming into Western North America prevented the record Gulf Coast snowstorm from coming up the coast. Our last impressive MJO 8 was back in January 2022 allowing the Pacific Jet to relax and the great snowstorms to affect ACY-ISP-BOS.

62f, Sunny.....torch-like?

Northern red is at full peak. Oaks running a little behind this year in color, but most are nearing peak now.

Great Notre Dame football game last night in the snow showers!

The LES event will follow from the circulation of a synoptic event that brought snow from Chicago to Detroit and will deliver an appreciable/significant snowfall in Ottawa, Montreal and Quebec City.

Chicago is about to get hammered by a huge winter storM. Holy crap. Feet of snow possible.

Thanks, Chris. It still was a 6 day long phase 8 last January (Jan 7-12) that peaked at a decent amplitude of 2.1. I consider that near an average length phase 8 in January rather than brief. Phase 8’s 6 days was as long or longer than any other phase last January as it went around to phase 4. Granted, the average amplitude of the 6 days in phase 8 wasn’t nearly as high as that of phases 1-4, which were closer to 2 and thus not as pronounced an amplitude as those as you said, but it still averaged ~1.3, a moderate phase 8. I consider weak to be <1, moderate 1-2, and strong 2+. So, I have it as an avg length near avg amplitude phase 8 during last Jan. I have phases 1-3 of last Jan at higher than average amp and fairly close to an avg length overall. Phase 4’s amp was closer to avg. *Edited last 2 sentences

It’s all lake effect

I've been occasionally browsing these myself. Nice of him to provide an explanation here of how it works/what it does/what it's doing.

Nice downpour happening.

happy for you all in the lake effect bands, grass is partially covered here, and we've had some steady flakes over the past hour.

63F

I did the same. As I am looking out the window its ripping fatties(oak leaves) and covering up the area I just cleared.

Yeah, the Great Lakes have been getting the heaviest snows with all these cutter and hugger storm tracks in recent years.

I'm in River North. I moved to Chicago back in the spring and never thought I'd see LES of this magnitude. Looking forward to experiencing this.

Looks like I’m up near three quarters of an inch already. Was not expecting nearly this much.

Sun is poking out in Manhattan. Hope the rain here is just light ….

The conversational flurries seem to want to go south to Richmond. When have we heard that story before...

That’s an aggressive forecast.
