Typhoon Tip

just a psychobabble guess but it 'might' have something to do with the fact that the forecast doesn't have a chance of rain changing to snow barely two f days from now. When that's the case, it kind of takes the joy out of a day like this ... curse for being weather-aware. Lot of folk don't even really look or care to look at the 'cast, they just head out - great! But if we know it's got a short window it kind of sours it a bit. Top 3 if not top 1 day here as far as I can tell. DP 42 with 79 and wind down to zephyr breezes ... not sure what else Earth can do to sponge bathe our balls and bring us deserts...

79

Quite possibly the best symbolic metric for that is the fact that the nights won’t be nearly as cold. This will cause a healthy status of green up to go full on jungle by the end of the week. Frankly, I’m amazed green ups as far as it is the way it’s been dipping into 37 every night for the past 7000 years

Euro's putting up big heat numbers in NYC's metro west and N NJ on Wednesday.

fascinating ... you can kind of see the weakening - don't have to wait for this to rotate away per se, it's seems to be losing identity at the same time.

90 Sunday in the interior if these new NAM 12z grid numebrs are right. I don't think its profile over Logan is right 18z+, tho. NAM is spuriously cooling the 850 mb level where it should be roasting them because that day has a westerly wind burst in the BL to 20 kts coming down from 280 degree direction, under superb solar max heating (off a high launch no less...). The mixing quotient should have that level closer to what it's doing over LGA, rising a couple clicks...not falling. So, it keeps the exit temp in the 82 range via adiabats when it should be about 91 given so going to toss ... It will be interesting to start delving into these kind of OCD inspections when the new model versions cripple the forecast community in a couple of months. HAHA

You know this reminds me ... I was just reading an article at phys.org ( paraphrasing site for deeper dive science papers ) that shows CC precipitation distribution is doing two aspect concurrently, world over. Water boarding gasping rates where it actually rains, while simultaneously ...everyone is getting drier ( on land of course..) in the general layout. I guess implying less opportunities. Intuitively this is probably more true in the interior of continents than it is around the seagull's range from the coasts. Anyway, what you described fits how a location might express the same. I guess wait until you get a slow mover in late June and the babbling creek under the street down the way suddenly flows over the road, scouring it completely away off a weather forecast for isolated thunder but primarily just partly sunny warm, high of 87

yes it was! And I don't have any faith in seasonal outlooks so you've manage to penetrate my cynical lead on this one. Ha... I nailed the first 1/2 of winter; didn't do so good in the 2nd. Having said that, I also did not formalize any outlook so ... heh. I guess it doesn't count. Maybe if I had put the time in I might have thought differently about the back half but I bet I would have had trouble getting out of my own way. See, for NINA-decaying springs - according to my own linear eval of correlations of other ENSO of past vs the cosmic dildo - there's an interesting 2ndary offset mode for bombastically warm AMJ. As 2ndary implies, it's not the leading mode. But there's a cluster. So they don't always happen, but the ones that did went impressively warm. I felt 'hot' on the dice roll. I took a rather quick and glib gamble that CC would team up and weight the die - this could be one of those years to see an early spring. And for those of us that covet bombastically decisive endings and warm flips ...yay. Didn't really pan out. But here's the funny thing... as an after thought, CC is fucking up the analysis, anyway. See, we keep cooking up positive anomalies in the relative comparisons of just about everything. That makes is hard to parse out what is happening because of what. Example, March and April we regionally were above normal relative to climate... during a colder pattern construct. Oops. We did however bottom of the barrel below the results relative to the whole U.S., so pattern still expressed. It's like we have parallel processes going on.

Mm ...he may partially be right ... I've been watching this and comparing it to various guidance. When this region pivots N, and it's not 'filling' in or back redeveloping as it's been pushing coherently N, it's like to shut off the spigot pretty abruptly. We lull... question is, would there then be a rejuvenation as a kind of weak easterly anomaly conveyor temporarily sets up while the filling closed low rolls underneath... ? Maybe. The NAM is paltry with that tho. And given the weakening kinematics ...that's not necessarily tossed. In other words, I can see a pathway to where your neck of the woods gets kind of shafted here https://weather.cod.edu/satrad/?parms=subregional-Mid_Atlantic-02-24-1-100-1&checked=map&colorbar=undefined

that's a good point. Didn't consider that. I tell you what ...I bet now that we're in the solar max we may still do better. I'll let it ride and take the hit if I'm wrong. I'm still thinking 77's doable but yeah. Part of my thinking is that we're facing a pretty significant built in correction vector, one with an explosively long room, too. As an aside, this really is an impressive wholesale change coming after tomorrow Just sayn', 2-m in NAM's 69 at ORH and 71 BED at 18z. That's garbage under near full sun and superb wind direction during a summer mixing profile. BL is gonna get tall. We all know FIT/ASH/BED are 6 F warmer than ORH in that setting. Granted MET MOS is 75 so ... it's a nerd's quibble.

Also, entertaining low grade heat wave Mon-Wed. 89-92 variety... close. Subtle yet crucially amplifying ridge heights are situated nicely for deep layer heat transport in recent multi-source guidance. It could tick more pronounced yet, too. Also, no BD or N-door frontal sag until perhaps too late on Wed to matter. Meanwhile, 850s are steadily improving from 10 all the way to 16c thru the weekend prior, and the general cloud RH fields are < 60% so sun soaking after elevating successive launch temperatures. Not big heat by very warm. Civility taken off guard a little...despite technical above average April it really has not sensibly appealed that way.

I'd use MAV for Saturday. METs not high enough for those synoptic params. If you look at the 850s warming from 15 thru 21z in a pocket just E of over the water, that's actually mixed diurnal plume leaving the coast - which means the mix hgt actually made that level. It's 10C, and the adiabtic extrapolation to 1000 mb is 22.5 ...so the mandatory 2 to 3 slope addition to the real sfc yields closer to 25 C ( 77), which is what the MAV sports. That could also be a deg shy, too

Wow... impressive 6 hour change Saturday morning in this new NAM grid. Walking through a summer doorway

The heaviest rain this system ordeal has to offer may in fact come from this introductory band that Brian just showed there. The whole system is closing off but that behavior is doing so over pallid gradients/weak baroclinicity, while the mid and upper heights are really filling as it closes ... not deepening further. As it is pulling away, it even opens the trough back up and ends up almost washed out of the hemisphere by the next day as it's corps smears up over the Maritime. [edit, it actually does go through another deepening phase up there but then right after it's disappears] Systems tend to not score well in the course when they're limping into the final. The NAM's lower QPF all along may end up doing better in this. The other models "might" be over producing QPF given weakening structure. It'll be interesting to see what happens with this. It is still a closed circulation, tho maintaining a progressive movement ... but closed circulations may get a window of easterly anomaly which adds ... So both a lower and upper performance are true.

Oh geez - personally have no experience yet working with these tools set to replace the existing ... I was talking to Wiz' yesterday, just the roll-out in August could end up a cluster fuck. So many tech suites have the present existing modeling tools deeply integrated, soup to nuts, and all that has to be reworked. Graphical processing alone - eesh So if on top of all that headache, it's to put a piece of shit bad models into play? haha. Sounds like a governmental operation, huh
