ORH_wxman

ORH has been slightly BN for snowfall in December but not by a lot. November was a goose egg though so seasonal is behind by a 2-3” more.

Need a panic thread. Not sure I can tale the toddler whining much longer.

Seems like most should get measurable but 2”+ will probably be in isolated pockets or out on/near Cape.

Nothing big. It did show a light snow event on 1/4. 1/6 is still there too actually but again, not a biggie.

I always tell people that overselling CC is just as anti-science as denying its existence. People should recognize both of those. But I’m with @dendrite….this isn’t the time to be clogging up the main thread with this debate.

The irony of getting into a global warming debate when we’ve been like -5 so far this winter. You’d think it would be in a +5 winter.

2009-2011 was the lowest 2-year NAO on record

Ensembles did get worse for both threats too just to be clear…but they didn’t eliminate them. I’d like to see it a bit healthier at 12z.

I know we were told that the NAO was going to be predominately positive due to global warming….we went through a big +NAO period in the 1980s/1990s and lots of papers came out about it being attributed to global warming. Then we got a huge decadal period of -NAO between about 2000-2001 and 2018 which coincided with the snowiest 15 year stretch on record in many SNE stations. It’s taught me not to have knee-jerk reactions about 5 or even 10+ trends and trying to extrapolate based on those. They just aren’t very predictable. A lot of climate weenies love to undersell the stochastic aspect of many of these patterns. It doesn’t mean we’re not warming…we can measure that we are and the literature is pretty sound about it on the whole…but it means other pattern attributes and sensible wx isn’t necessarily as easily predictable or understood by climate modeling.

Maybe. I wouldn’t be tossing a system that is over a week out though. And especially not one that is 10 days out. They may not happen. If that ridge rolls over, we’ll actually get mild for a few days, and that could set off some melts in here but there’s a very strong signal for a reload of the ridging out west and up into AK beyond that both on EPS/GEFS and the weeklies, so I think we’re going to continue to have chances. Obviously we want to start hitting on a few…we’ve already done plenty of cold with little snow this year.

1/8-9 looks worse today because the ridge is further east now. Need that further west. I’d still watch both that system and 1/6 though. There’s still a signal for both on the ensembles even if it’s not as strong.

Right…there’s a reason they are like 1 in 50 or 1 in 100 year storms instead of 1 in 500

We’ve talked about this before, but there’s probably some perfect chain of events that produces a sub-950 bomb southeast of LI starting from relatively higher pressure….preceded by some sort of high-thermal gradient overrunning scenario that lasts 24+ hours before the slow moving shallow trough is injected with polar/arctic energy, deepens extremely rapidly, and produces 5-foot totals once you add the entire thing up. Yeah…1 in 500 years maybe? But it’s not zero.

For me, that bigger storm can win but it has to be pretty rare. Taking a 15” storm that melts in 3 days over a handful of 5-6” events with prolonged cold is an easy no for me. But if we’re talking a 30-burger over 3 foot-longs, sure…the 30-burger is pretty special.

Radar looks good

Most people here would probably take 2-3 storms that add up to 25” with long duration colder temps than a 19” storm that melts away in 4 days. But I can see those who just enjoy the storm picking the 19-spot. Obviously if we waste a good pattern with very little snow, we’d all take the 19 burger.

Looks pretty decent south side of BAF/CEF

1/6 could morph into something worth tracking if we can get it inside 6 days. The larger signal is 1/8-9 but that has a ways to go. But overall a good pattern coming up. Nice to have in early January for once. Feels like we’ve been fighting garbage patterns in early January so often over the last decade or even longer. We had a lot of good early Januarys in the 2009-2014 time frame. Since then I feel like maybe only 2018…maybe 2024 if we want to count that one threat on 1/7 but it really wasn’t a cold pattern at all.

Yeah euro still generates a system on 1/8-1/9 but it’s a bit strung out and weak going almost due north and scraping eastern areas. It doesn’t take much mental gymnastics to see that thing being much stronger and more coherent. The PNA ridge is pretty amplified which is going to want to force a lot of energy to pile up around the base of the trough.

Yeah the NESIS maps are good for general coverage idea. They are often wayyyyy too conservative in the jackpot regions. The Kocin maps in the book are much better at showing those.

1/6 looks decent on Euro today. Moderate 3-6 type event.

That New years weak clipper is trying to get slightly enhanced in eastern areas. Wonder if someone can pick up a couple inches. Still just expecting a coating but 1-2 isn’t impossible.

Has another period of interest a few days later too. Obviously the further you go out, the more diffuse the mean gets but that’s definitely still something.

This is pretty solid for 200+ hours…forget the OP runs for a bit…maybe it doesn’t work out but you have a very definitive signal there

Which part of Haverhill? Lol. I think the northern side is where there was 7” of sand. Massive cutoff near there.
