There have always been misses and rough stretches during which the misses far outnumbered the hits. 1 1 Link to comment Share on other sites More sharing options...

I know you guys concentrate on big storms, but I actually have noticed that sometimes a wetter climate does lead to MORE snow in northern climates than it wouldve seemingly produced in the past during a similarly hostile pattern/base state. 1 Link to comment Share on other sites More sharing options...

Usually in the form of one big storm. It has juiced up the atmosphere, which is why 2015-16 was snowier than 1982-83 although it was warmer too. 1 Link to comment Share on other sites More sharing options...

Yea, I think that is applicable more for your area through the LES belts and into NNE....but I do agree with Chris that CC maybe starting to infringe on SNE snowfall climo....at least a portion of SNE, anyway. That said, we are simply in a hostile pattern for SNE that is less so for your area over to NNE. 1 Link to comment Share on other sites More sharing options...

bluewave Posted 9 hours ago Share Posted 9 hours ago 19 hours ago, 40/70 Benchmark said: It was off the west coast when the storm took place, which is all that matters. Yes, the jet was a factor, but so isn't the poor positioning of the ridge. I don't know why you inexoprably seek agreement on a 100% CC attribution for everything. My pointing out a particular repeating pattern over time with our storm tracks leading to less snow is more about pattern recognition on my part. I use it in real time to point out that the models have been too snowy beyond 5 days. This has lead to the famous modeled snowstorm always being a week a way. Which is due to the models underestimating the influence of the Pacific Jet longer range. Adding extra warmth to the system in multiple locations causes shifts in the storm tracks. So we need to acknowledge this as a forecast aid. Link to comment Share on other sites More sharing options...

Yes, when we have great winter patterns in place the snowstorms can often overperferform relative to longer range model forecasts. But since February 2022 most of the snowstorms have been in the long range only to disappear once the models catch onto how strong the Pacific Jet is under 120 hrs. So in effect these models aren’t well suited for such a fast Pacific Flow regime. Our only two colder and snowier months in the 2020s have been February 2021 and January 2022. 1 Link to comment Share on other sites More sharing options...

I agree 100% models are too snowy. I've been an unapologetic snow lover all my life and started following snow threats religiously since the 72/73 winter. Since then when modeling was first being used as a tool, they have ALWAYS been too snowy beyond 24 hours. I can remember complaining to a friend in high school (before 1976) that the model forecasts were too snowy. My point is, modeling has always been too snowy outside of 24 hours for a variety of reasons and to use recent years' snowy +24 hours modeling errors as proof of anything is a mistake imho. 1 Link to comment Share on other sites More sharing options...

Models are too a lot of things, not just too snowy. Case in point, last year the gfs, accounting for the 3 runs per day, had philly over 100° more than 80x. The Euro was better, but it still had them over 100 numerous times. Philly reached 100 zero times last year. A nws met tracks this on a Philly board, so im not making it up. Too snowy. Too cold, but also yes, too hot. I know some can't handle that last one. 1 1 Link to comment Share on other sites More sharing options...

I think the rainy conditions to our west and the tendency once again of over-the-top heat and steep ridge patterns means our summer will probably be humid and hot but not excessively so. We'll hit 95 a few times but outside of Newark once or twice maybe no 100s. With the steep ridge we can't get the warming downslope westerly flow and instead drown in FL-like humidity with S flow. And that means the coast likely goes into summer drought mode stuck in the marine layer while inland gets the T-storms unless we can get a more organized system to drive them to the coast. I'm glad we all had the rainy May so we can stock up before it inevitably dries out for summer. We might already be starting it on the modeling which shows heavy rain inland and relatively dry NYC east. Link to comment Share on other sites More sharing options...

So we need to acknowledge this as a forecast aid. I'm not arguing that the active jet isn't inhibiting snowfall opportunities, or that forecasters shouldn't be mindful of it. My point it that it wasn't the only reason we didn't see a large east coast snowstorm last year. That said, I also think the jet plays a role making it more difficult to get a well placed PNA ridge. Its both. Link to comment Share on other sites More sharing options...
snowman19 Posted 6 hours ago Share Posted 6 hours ago My confidence is increasing in at least a cold-neutral, possible weak La Niña forming this summer/fall.

I recall that username, messenger. Sorry to hear he passed. 2004-05 was an excellent winter here. One of the rare times when we both got slammed from the same storm (Jan 22-23). The most annoying thing about that winter was a handful of bad measurements at DTW; they ended up with 64" and I had 80". There's always the occasional storm you question, but that was the last winter I really was unhappy with DTW measurements (I know with nyc that's every year ). There were a few events that had razor cutoff so I did get more than them anyway, but id estimate they were really in the low 70s. 1 Link to comment Share on other sites More sharing options...

For reference, the hottest temp on record is 105° (1934). The end result is that 2023 was the first year since 1915 where Detroit didn't eclipse 90°. 1 Link to comment Share on other sites More sharing options...

Which end of neutral is the question yet to be answered. Either way, RONI will probably be on the Niña neutral end, if not weak Niña territory methinks.

Stormchaserchuck1 Posted 4 hours ago Share Posted 4 hours ago Subsurface looks like there could be some warming over the next few months.. warmth is just below the surface. There is a big difference though between CPC and TAO/Triton maps. CPC has +2-3 subsurface anomalies in the thermocline where TAO shows negative.

I wanted to share something, not sure how accurate this is, but I found this while looking up big heat https://www.reddit.com/r/newyorkcity/comments/1epkptr/central_park_ny_highest_maximum_temperature_f/ That 106° reading was on 07/09/1936 during the incredible 1936 heatwave that effected most of the US from the Midwest to the east coast. It was the highest temperature ever recorded in NYC. In those days the official weather bureau temperature was measured at the old Battery Maritime Building near Battery Park where it was always a little cooler due to it's proximity to the water. So the actual temperature in midtown may have been more like 112° if not higher. My mother remembered that heat wave and said that people left their tenement windows open during the day even if they were at work. A very different city then.
