Then hopefully we can grab a big dog before calling it a season. Exactly. Link to comment Share on other sites More sharing options...

Not sure why their graphic says 13.5….even the map shows 20s over central MA. But yeah….that one was a doozy. Already a lot of snow OTG prior to it too. 3 Link to comment Share on other sites More sharing options...
Sey-Mour Snow Posted February 11, 2023 Share Posted February 11, 2023 Weenie range of ensembles still looking cold. Let’s see how long this lasts and if we can get it into day 10. Would be nice to sneak in a wintry few weeks from Feb 25-March 15th then flip warm in a perfect world. 2 Link to comment Share on other sites More sharing options...

Can’t wait for the nudity to envelop us all. It's sooo close to being a legit 'heat burst' - not that there is any kind of formal definition for what heat burst means. I figure it's gotta feel actually really warm, and not just high 'nape' value - not that there is any kind of formal definition for what nape means ... etc etc. LOL. Seriously though, it's a new kind of phenomenon, the likes of which - for me anyway... - I had never experienced in my ...ah, let's call it 'multi-decades' life span. Anyway, its when any winter month hosts a period of summer temperatures. It's obviously less likely in Dec and Jan. Those two months don't have the advantage of the sun leaving the solar minimum era of the total solar calendar - which is the case in February. That's prooobably a prerequisite for this sort of thing. Although, I've seen it be 74 in Dec... once, back in 1999 I think it was. Even if it's only 12 hours... I figure 75 is the fair distinction. Otherwise it's just global warming in the air - haha. Probably shouldn't refer to these sudden synoptic heat plume events as heat bursts, though, as the name is already designated in the AMS Glossary. Thermodynamics are complex, but outflow from convection causes an explosive rise in temperatures - counter intuitive to the idea of cold outflow. But what happens is, the air goes through extreme/rapid drying, and then is compressed. It's more common where mountain topography vanishes out into a lower planar region - I've heard of heat bursts raising the temperature from 55 to 103 in S. Dakota for example... what the f am I talking about. I just wanted a distinction for the 'special' 2017, 2018, and 2020 type summer flash synoptics. That as a specific characterization separates its self from like yesterdays 'historic' aspects. 1 Link to comment Share on other sites More sharing options...

Typhoon Tip Posted February 11, 2023 Share Posted February 11, 2023 58 minutes ago, Damage In Tolland said: It’s a Sonoran Sort of ..yeah. The total Sonoran heat release model is - to me ... because I'm a staggering dork - fascinating synoptically. What actually happens is, it is led off by a period of +PNAP. Not necessarily a "+PNA" - there is an important distinction between the two. The +PNA involves the total local hemispheric manifold/circulation mode, from basically the Date Line across N/A. I think the exact coordinates can be found ..etc. But when we say PNAP, we refer to the Perennial North American Pattern. That pattern is described by a modest 'bulge' in the basal flow characteristics, in the heights over western N/A, due to the prevailing westerly flow incurring upon the western N/A mountain cordillera. The flow rises over it, and then the C-force causes it to turn polarward. A standing ridge becomes discernible over the perennial mean. The flow then tapers back S as it's leaving eastern N/A. That distinction offers an opportunity to distinguish 'event machinery' - PNA tied to total atmospheric modes/modality, whereas + OR - PNAP can move with that, or just be transitively influenced ... Similar to the NAO in that respect. The NAO demos more stochastic observation of its mode states because these stem wound maritime bombs occasionally sequence through that domain space ... setting off quickly recovering negative and positive index values. They may not represent the longer term return mode, either... - gets into headaches. So anyway, with the "SHR" ... the modest +PNAP "caps" heat and it cooks over couple of few days... really loading an H850 level kinetically charged layer.. This layer is pretty evident on soundings; often associated with an EML type profiles... but the two can exists independently.. So what happens is, the +PNAP gets perturbed and tries to go negative - if not succeeding. This dislodges said plume of KC8 air ... Given the amount of -PNAP determines the arc in which the KC8 ejection moves down stream... Sometimes it's south through the TV ...Other times it takes the N route - "Hot Saturday"/ Aug '75 was an ejected plume that got caught up and rattled around the N route and came down from the NW. That's why our hottest summer events come from a W or W/NW direction. That whole long-ass sermon above may or may not have preceded the 2017, 2018, 2020 events...etc. It is likely too early in the year to cook up the KC8 layer ..etc. But, we can certainly get a very amplified -PNAP and/or -PNA, that pulls air out of Tx ( for example ...) - 'quasi' creates a weak variation on the same overall theme. 1 Link to comment Share on other sites More sharing options...

The deepest cold is still way out west. The big troughing still out west. Storms are going to want to amplify early just east of the Rockies and bend back, producing high risk of warm sectoring, around here. This look is shit for 75%.

Everyone else fighting warm sectors and ptype issues.The thing that’s striking is that if the widely hyped SSW is going to downwell to the troposphere and do something to the polar/arctic fields you want to start seeing some sort of response with the NAM/AO and NAO. That’s not happening on the models through 2/28. It’s +AO/+NAO right through. If we get to the 1st week of March and there’s still no response or at least one definitely imminent, I doubt it’s ever going to happen Link to comment Share on other sites More sharing options...

What actually happens in March ??? I would think the AO/NAO at least become less hostile and maybe some blocking develops but I seriously doubt the RNA goes away. If you read my last blog update, RNA is here to stay. That is on par with 1956 analog. I was right about the break from it in January, but unfortunately is was heavily west-based. 1 Link to comment Share on other sites More sharing options...

I’m most concerned by this look as it means more pack building in Northern ME, QC and NB, which I think is a harbinger of a significant -NAO developing in March. This in turn keeps storm tracks Mid Atlantic—>south. If you’re looking for mean reversion - N to BN and dry would be it. And that’s also multi year persistence. I hope this is dead wrong.

Its tough to remind people of this during the winter of Murphy's law, but RNA/-NAO can be glorious when the energy doesn't dig to baja. Keep rifling PAC waves into a block.
