Typhoon Tip

Tomorrow is a downslope dandy day.... That's got super-adiabatic surface T's written all over it.. Prolly is full sun, light wind 62 F right to the coast.

Just speaking to the operational Euro's 00z 03/26/2020 solution ... I thought the block looked less... D-7-10 clearly shows that collapsing into the west Atlantic basin perennial ridge...BUT, there is a better homage to a +PNAP and cold loading into SE Canada, too ...so, perhaps either way. The GGEM was also looking rather betrayed with the scale-degree of NAO too... heh. The other thing I'm thinking, even for the Euro ...all these guidance' are going to prove again that they suffer sun-normalization at a hemispheric scale ... can't be avoided given the current state of tech art in modeling and the fact that it's after the Equinox. The modulation in the physics is an 'acceleration' of sort, albeit subtle... it is a stalker to cold solutions. I have seen countless D 9 deep 500 mb solutions at this time of year, that look like an assumption of a deeper surface evolution would be fine. But what ends up happening is strong mid level anomaly with weaker pressure responses underneath... kind of grapple showers in the hills and cool rains showers under pan-cake shallow toppers. What happens is the baroclinicity gets normalized by punishing irradiance in the days leading. Not sure why the models don't seem to handle this kind of "synergistic" reduction in the barclinicity in spring so well, but even here, ...that deep trough the Euro engineers ends up with a broad, but less deep low comparatively... That's sort of a hint some of this is happening- That all said...we've had blizzards in early April... not discounting that climo either ... It's really like everything, it's a processes of dwindling probabilities for returns at this time of year...and if something does happen in early April, it just means that the anomaly was sufficient to offset seasonal forcing -

-NAO however ... the modeling for that particular index has delivered more betrayals than I care to count. Also, it is the time of the year where faux modes are more common. That said, the best way to get late March/early April event would be to have that GEF's derivatives actually take place, so if one is holding out hope ... it's a good start to at least see both agencies crashing the NAO index from +3 all the way to -2 ... That, while is matched with operational runs depicting west-based blocking nodes. Too bad.. everything about reality is dour .. it's weird. Pandemics and no winter, and no spring -

Odd behavior with this thing.. We snowed moderately and steady later yesterday afternoon and early evening to almost 4" ..then, flipped to sleet and cold rain as the temperature was falling to 32.5. The mat-downing was underway by 7 .. 7:30 pm ...Then, the wind picks up with ominous whirs, and everything flashed over to heavy snow that went on to burst for about 1.5 hours worth and another 3"... Then, back over to cold rain and sleet.. Bit of a head scratch because this later flip back was amid the genesis of the CCB featuring on rad and sat, and in theory, the column should have continued to cool. But it seemed to warm during that period of time. Interesting. Not sure how the event finished, but by 3 am the sky was just black, there was no wind, and glop flopping rained from the trees. Too bad, too, it stripped the gracing off the trees and that would have been a pretty specter at sun-up but.

Hammering in Ayer

Epic bright band through the state looks like dynamics are totally kicking model ass

Epic flashover the heavy snow and wind here

yup ... it will be a nerd's paradise watching that transition as a CCB gets going and this thing stationary's then start moving SW.. The big pivot!

there it is...33 ... vis now est .5 mi is light/mod small aggregate snow.

This ptype monitoring could be complex. The expectation gets muddled by the marginal nature vs the dynamics/mechanics of this whole system. The pings and transition could march N in January ... while we marginal below that level - oy. Confused further, if the elevated centers close off and heights decimal implode that little amount then we start snow growth at lower levels and do that whole 33 back over to snow thing when/if a CCB also concurrently gets more NE trajectory/organized. At which time, the snow line collapses SE with the BL temp maybe even a degree or two warmer than now. Right now we have BL flow that is ESE here but that seems to be relaxing as the cold profile has been taking over, so we are probably getting some low lvl damming from wetbulbing going too.

small uniform aggregates here in Ayer at (supposedly ...) 35 F ... but, that's shaved 4 in 30 minutes, so at this rate and considering the DP is 29...we're probably heading to 31 F by next hour I'm guessing... Vis about 1.25 (est) and the fall is flitting around in the breeze not acting like it's very wet -

Ugh yeah... who knows. I do know my spring climo around here as we all do and gossamer warm layers out ahead of these kind of blue deals isn't that uncommon in spring. interesting

yeah, that too - calibrations not withstanding... I'm gonna go ahead and assume it's 33.1 or something... The snow really is flitting around like light and gingerly ...not 'wet' in nature. I mean we'll see how long it last...just at onset here. Looks like January from the window

all these home stations in Wunder have it 36 to 39 within a couple clicks of mi casa yet the snow aggregation is of the mid-small variety... This must be a very narrow ( typical for spring ) warm layer at the bottom.

we have medium small flakes here in Ayer in the last 10 minutes...

I'm not sure .. keep us posted, I'm curous. I'm looking around at event entry T/DP spreads, and knowing the thickness intervals, and the synopsis of this closing off centers south ... mm, the only thing going for this as a rain event is climo- but ...we know what that means. Anyway, I curious how this works out because this 'looks' per these observations like a straight up snow event to me...say HFD-NW RI to I-95 eastern MA...with dollar sized cat paws at Logan

Testament to the marginal nature of this... decimals mean 10" of wet snow vs 4" of slush vs cat paws, and that's probably within the technological margin for error ...

well... when has the "Kochera/2" rule ever been different anyway -

'What' is/was a trope that is commonly used in parlance to signify, 'think about it' You're question was unusual - and outmoded frankly. You didn't state 'why' you asked it...in a vacuum it made less sense base on what is both proven and common wisdom. People don't know what they are looking at with aerial vantage and information flux so they attack - the bottom line is, any D.C. outdoor event is safer than any such engagement indoors. So if officials were 'hunted' that is because 'people' have too much access and don't know how to analytically take it in.

what ... ? no... warm weather spreads animal behavior - that's consistent in human interactivity as well... Cold weather drives people inside as a sociological rule, and that is a incubation paradigm that favors/fosters virulence by giving pathogens precisely what they need: contact... There is no comparison between multiple individuals concentrating their bio-phage inside among one-another, and a bunch of individuals in an open field with open air circulation offering ventilation... eating barbeque on paper plates...

I'm so buckin' for this... I hope they land on their seasonal total, right down to the decimal, just so we have to give the year a passing grade. Anything worse is biased and personal, proving this entire engagement is a waste of time and that we are all neurotically lost in one's own tormented bs... That's more dystopian than any blizzard or Global pandemic, too - some might call that hell. hahaha

Unfortunately ... I don't want them ... not that anyone cares - But, I'd really rather 80 F weather drive the diaspora of people out among the openness ... you know, spread out ... so virus-choking healthfulness gives peace a f'n chance.

Seems like getting an event to actually happen this time, the trial and error game of this last winter ( despite now being spring...), finally does. That was the gist of my conversation with outside Mets over the winter, was the striking neggie interference pattern at all scales, ... damping events, period. It was much less an issue of available cold. There were two tendencies ...well, 'persistence' may be more apropos: systems modulating W; systems modulating weaker. These were the correction vectors that took place ... in every case ...Since the Dec 2019 event. I strongly suspect gradient saturation and velocity were the main culprits ..as I've championed the cause all along. This has been a large scale negative interference pattern pummeling the mid and shorter scales... pretty much unrelenting, the whole time...the whole way. Now, the flow is relaxing as it typically does at the tail end of the season, and we have a chance - go wonder - for a 'well-behaved' cyclone in the models to actually f'ing take place. It all seems really simple to me: take away the limiting factor of a crushing +AO and an unmitigating Hadley Cell also squeezing into the mid latitudes, and things can happen/parlay. About a month ago I posted that I thought we had a chance to recoup on the season when the pattern relaxed.. The EPO came right on schedule... - we'll have to see if we can get a -NAO transience in here...Some oper. GFS runs have been trying to flag that. Anyway, still two events in the pipe line for this week, which is a testament to the better cyclone vitality of this season ending advantage, they have been remarkably stable in all guidance ( save for details).

Nahh it’s gonna be right sorry. Winter sucked but oh well

Nah...it'd be so glop wet it'd fall off in slush gloops before it can weight anything to tension - I've seen that before.. Like 4:1 silver snow ... the trees bend even a little and the burden slides off blat rains Your really don't want it more wet than ...I dunno 7 or 8:1
