Typhoon Tip

84/ 66 ...can feel it. Just ( admittedly ) installed upstairs. I'm actually likely investing in mini-split tech over the next year, so installing will be a thing of the past. Friend of mine had those installed and said it's amazing how well they control the environmental RH and T, and don't really inflate e-bills.

81 here 6 ahead of yesterday ...

Yeeeah... barring things changing. In simple, looks like 3 or 4 days of relative heat here in the near term... 3 days of seasonal cool back ( probably more beautiful than annoying), followed by perhaps a repeat of 3 or 4 days --> Mem Day trace of snow at Tolland CT ... --> then we'll see if there a bigger heat signal into June. subject to change of course -

Yup, same here! All major species are flowering and leafing and not just figuratively, last week at this time only half were and many were nuclear still. First week of May no less.. There's been mixed opinion on whether this is was 'late' or not. Not here to argue. It may not have been. But I also suggest that we may have just come through 15 years where we've gotten used to earlier greening? so maybe this was more '1,000 year normal' so to speak. I don't know. But I personally know that several of the giant sugar Maples around my neighborhood were two weeks later than last year. It may be local noise too -

Yup! It's hard to do a more discrete reanalytic study of it. Heat waves were always either not recognized, or disrespected perhaps ... prior to Climate Change. But now? Their lead synoptic signals..et al, are finally getting recognition. I've opined this for years... but in short, the big five were always, "Tornadoes, Hurricane, Floods, Droughts, and Blizzards" (no particular order) Years ago... after some cold waves in the late 1980s were inspiringly gelid, and then the 1995 midwest heat dome nothwitstanding... I began to wonder why Heat(Cold) Waves were not included/expanded into that list. I mean hell...they actually incur significant commerce losses, not just health and safety - I mean the latter should have been enough, right? LOL. As to the heat source stuff... ah, just per my experience, I don't think so, anecdotally. I think back to the sweltering big dawg heat events of lore here, there's a kind of 'over-top' aspect to them. It's when the SW "volcano" belches a fire-ball into the flow. It smears out as it moves arcing over the top of a -PNAP coupled positive anomaly ...usually situated near Dayton OH... It's actually kinetically charged air that is by convention not saddled with surpluse theta-e.. That mixture of bio- continental ozone actually gets the HI up more so than the temperatures. So the "clean heat" descends on a NW or WNW trajectory, down sloping no less. We really have not seen that in recent years. The closest I saw to us getting Pac NW event here, was 2017 ... July 4 weekend. But it fell short because despite the historic non-hydrostatic heights ....towering to 606 dm!!!, there was no SW ejection into that pattern formulation. So we home grew/cooked our way to 96's over 75's within that Venetian height dome that actually left some on the table. The SW version that you describe - I would be more willing to guess is prevalent during sustaining warm seasonal biases, on whole.. Like you you know, the maintenance 91/75 crap, that only goes back to 87/64 before creeping back up, because there's a semi perm SE ridge tendency. That was like some of those 1980s and 1990s summers. 1995 had the big midwest/Lakes heat bomb, and that one certainly does match your notion of NW flow 'shearing' off the really bread oven stuff from getting in here... But that's a unique scenario... "Hot Saturday" in 1975 was kinetically charged plume that came down from 'over-top'.

Yeah...and in all seriousness, we do have to keep an eye on it as heat synoptic enthusiasts. For that, and perhaps risk assessing. Through the end of the month. (Mem Day weekend will have pingers and 40 F rain whether it is 1,000 F book ending it, come hell or high water) The PNA is inconsistently negative, and that is precarious for an eventual Sonoran or SW heat release into the downstream flow. This is interesting to me ... both the GGEM and Euro oper's show a 570 non hydrostatic closed anticyclonic node up there over Alaska. That's -EPO incarnate. Noormally by now, that should not mean much? The seasonal R-wave structures break down toward summer entropy ..etc. But there is an insidiously hidden faster than normal velocity of geostrophic wind over the total planetary scaled integral. It's forcing those synoptic super-structures to lag perhaps longer than normal. So a -EPO up there, crashing heights down the Great Basin couplet, sends heights up in the OV...viola! that drags the SW heat out and there we go. The GGEM flat out does that D8-10 ( 00z oper.).. It's ensemble mean is less though. But the oper run isn't impossible - it's showing what a slightly more amplified variant is capable of. That could still do all that despite the modestly -PNA/ +AO/NAO.

Mm hm ... sound analysis. And by extension ... that NW flow relaxing, then passes us through a structural interlude that risks BDs. It's like there are staged hurdles that need overcoming, in this order: NW --> BD --> laboring warm front from almost imperceptible surface CAD lag --> no apparent reason for warm frontal drag remains, yet it doesn't go through mystery --> finally... we're in the hot air ... for 10 minutes before a the main CF. Meanwhile everyine west of ALB got at least hot regardless of any of those scenarios ... ( yes this is dripping with snark )

If I had a goatee stroking muah hahaha weather machine and could like ... aim it? I would tease up an experiment where I programmed 38.47" inches of stalled 80 dbz thunderstorm rains ... Houston tropical storm style, right over his house and yard, just for the shear experimental muse of testing whether the frequency of those desiccation dystopian drought tweets might actually go down... That would be a neat experiment. And also, possibly even a working solution toward a reality where we never read one of those again!

Yeah..just wrote a tl;dr to Brain about the GFS next weekend. It may be right in principle, purely based on our sore-butt climate. Lol. But the way it is going about doing that is not likely correct, imho. It really appears to generate heat lows and then 'thinks' its own creation is a cold front after the fact. That would all by definition be an artifact - perhaps less true, but we'll see.

It's interesting ... hard to tell on satellite what's really going on down there. Clearly N of CT/RI, there is just fog pooling miasma that's melting away as I type. That's a no brainer for giving way to sear. But down there, there is a denser band that has S to N moving 'ripples' that give an allusion to a mid level ceiling ... perhaps helping to cap the region - imagining it collocates over top, in other words. I dunno tho. I think you will be probably be the last to clear - not sure how long.

I mean don't hold a pistol to our heads - LOL... Like we're saying, 'the way it looks at this moment'.

The EPS and GEFs means look tepid for signficant heat next weekend - Not sure the telecon derivatives would really suggest very hot either, ... just eyeballing the mass fields that are used for the calculating. It's a bouncing -PNA ( 0 to -.75 or so) with a modestly positive AO/NAO ... m'yeah it's warm. It is D7-10 so it could start getting more robust. This signal was in fact more robust two days ago ... I recall posting with Brian about it. So given that history, ..yeah I guess. It looks like we have a deep summer weekend for everyone but CT's south coast ( lol...j/k), then a whisky cold front along with its typical climo-failing convection threat that only manages to explode a pointless 20 page thread ... scrubs out and we get a couple of days that could actually be really nice. I mean breeze and upper 60s to around 70 style with ultra UV sun, mid week. I dunno tho - cold tends to modulate warmer at this time of year so the that nadir next week may shallow some. Then we oscillate back to something like this weekend ... That's what it looks like to me right at this moment..

No kidding?! I kept the evaluation coarse after I saw the 00z GFS. That model - I am now pretty much convinced ... - is forcibly parameterized to concoct interference of warm ups. lol. This rendition, it calves the eastern end of the warm front on Friday and generates a pivot point tendency for anti-cyclonic pressure pattern, very subtle. But then the next day, it creates a single close isobar over SNE - probably a 'thermal low' actually ... - but uses that as a trigger for a BD that doesn't actually have any assocatiated pressure rises up in Maine. It's like, "oh ... well, we better truncate that," while the GGEM and Euro are breaking records. It's probably right though, in principle. Heat's really fragile by nature. It's always trying to get to space with a leaning force always on. It's not like cold dense air, that needs real Newtonian first law mechanics to get it out of region (which we are uniquely qualified to demo around this geography ... ). So the GFS is "confusing" thermal lows with BD tapestry, or, we just BD anyway? right for the wrong reason is better than flat wrong in any dimension I guess.

Scent of summer in the air this morning, unmistakable. Sort of hinted yesterday, it piques the nostalgia with rich aroma. Same as yesterday morning, a morning strata -fog has packed in. Thinning from the edges, and brighter moments, will eventually open up to tall hot sun. Tomorrow looks like the first uncomfortable day. Quick surmise off the NAM grid, 90/60+ style. In fact ... deep summery bath all weekend. Maybe some afternoon crispy TCU ? On cue with elevating DPs and the modest CAPE. For summer enthusiasts, this is your time to celebrate -

NAM looks hot Saturday.

Sounds like -(S.A.D.D) ”Negative seasonal effective disorder” is a lesser known variant … probably because it affects a comparative minority, to the popular/known kind. … It’s just like it sounds. Summer/high sun causes problems for them, much in the same way that darkness and cold gets to the other.

I don’t get that vibe about this year. When summer mode takes over and the perennial shift lifts out the polar jet I don’t get the feeling we’re oscillating this time. May end up dull with towering heights. Maybe set the stage for cutting off a heat ulcer like ‘95

oh ok. the MOS reflects that. fine.

NAM appears to have come around to warmer per this 12z run. Given up on that strange low level RH contamination - it was putting out 95% choke in the bottom, under nil mid and U/A cloud ceilings/May sun; with the ocean flow cutting off, that wasn't clear where that was coming from. Anyway, the 980 mb over Logan surges to +24C on Saturday, 18z ...which is probably 27 or 28 C in the real 2-meter ( not what is displayed in those graphic charts that say 2-meter but stop at the adiabats). +22C above the 2-meter mixing depth tomorrow. That all translates probably the low 80s F even tomorrow, and mid/upper 80s Saturday.

67 at 10... '10 after 10' rule of thumb seems about right. Transparent strata appears too thin to be much limitation on heating. The strew float like islands in a much broader blue sky so ample sun. Denser E-S but even there it's trending less.. You know, we need the rain? My lawn - as a yokel's metric ... - is not growing/replacing very well for May after just one mowing... I don't recall having a decent soaking in quite some time. That coastal/cut-off ordeal didn't bring rains to much of the area - just choked off the sun and Labradorian flow kept the trees dormant. lol - but yeah.. heading into 4 days of 75 to 83 with low rain and high sun

Slate gray an hour ago here, but as hi res vis satellite imagery revealed...it was totally clear just NW. Mainly a S-E region, strata rebuild during the cooling darkness of the overnight. But now as the sun intervals burst through, the loop also reveals it's very thin. Should be clearing lowering RH quickly NW of ~ BOS-PVD. Sooner NW. Quite a milder feel to the still air this morning comparing recent mornings. Already 57 here. Higher launch pad. Looking at the low level gradient, very light. Even out at Logan is 'cast to stay under 10 mph, tho still NE. That's probably variable by Cambridge side. That does, however, set stage for the local sea-breeze circulation to set up.. So probably a boundary works inland toward I-95 and eventually 495 late afternoon. Should be upper 70s out here if/when that arrives - not certainty. It's a tedious, nerdy now cast to give a shit about a random still day in May but what can I say - that's the way I roll. lol

man... Davenport IA is presently 95/69 That's about what we seem to max out here. We need to trade off the DP to get that 95 --> 100. We have have been higher, just more typically..

Oh I see what it's doing and it's not likely right. It appears to be taking the return flow and mixing with the dry air in place, and wetbulbing the low-levels to near saturation. Least that's what it looks like. As the wind veers around to SW at ALB -for example- the llv RH jumps to 90+% at 18z Friday with blue sky over head, and the temperature there stagnates. That's BS

Made 73 here along Rt 2/eastern Mohawk Trail in N Mass... 75 in MHT, NH and 82 in ALB. Over top was a good call ... but now the question, does is bleed south. NAM says no... Not sure I buy it though. Boston staying 17C in T1 ( 980 MB level) with a WSW breeze under full sun, with 850s all the way at 14.5 C on Friday like the NAM's selling - wrong. Looks like it's trying to pollute the lower levels with surplus RH with no prior DP advection ... yeah it's doing something naughty. I wonder if the 'winter algorithms' are still firing in the guidance - used to be a factor in the old days. Maybe the seasonal change is seamless in the tech these days - no idea just conjecture. At any rate, synoptically it looks to me like 78 here tomorrow, and 80s on Friday. Saturday the pan-region tickles dp of 60 with the smell of distant thunder-able air.

I knew it was coming ... I didn't wanna mention it ahead of his announcing - who would? but yeah, memories galore. Great forecaster. Above all else, a great human being. Deserves all the credit and them some, as well as happiness and success in any new found directives, or in freedom.
