I don't disagree that low 90s may be in the cards here.  I sold the 95-100+ that's been thrown around

South wind will eventually hurt you down there to some extent like last time. Up here we roast off of the Monads and ORH hills.

While I doubt this will be any kind of record 6 day heat as hinted at by some, I might actually have to install on Saturday.

Why? 

I was thinking there is a definite tenor in the nightly runs to do ..may not 'records' but an extended heat wave at that... so "hinted by some" I assume you mean models, and you disagree with those models?  If so... why - just curious

Euro and GFS are hot for Sat-Mon. Back to 24C 850s up here.

Euro was exotically hot in the middle tropospheric heights from D6 to 10 over an unusually large aspect of North America, S of the 50th parallel... I don't think I have ever seen a geographically areal coverage occupy as much of the planetary medium as does the Euro's circumvallate of 594 DAM heights in those extended frames there.  (I'm just using ur post to gog ...jesus)

What's amusing and musing about that... is that the 850 mb temps, for all fair intents and purposes ...fails to really recede appreciably post this weekend ...effectively merging this heat pop over the  weekend with this latter continental inferno in its late mid range/extended.  

It  may not be 100 every day as is.  ..more like 90 to 99 would be supported ..but, every day...   

The NP-Lakes-OV-NE as advertised by NCEP decays the heat signal from west to east, from Sunday on...but, the decay fails to actually get here... Meanwhile, about mid week ... that climate-event-scaled ridge balloons and surges the heat back to those regions west ... by the end of the run, the whole everybody is immersed in it... NP-Lakes-OV-NE ... connected to West TX and Kansas.    

One thing that is missing?  We don't have an ejecta of SW air layers ... otherwise, that pattern would absolutely bizarrely max out - ... I almost wonder if that's just a matter of time anyway. Almost  

But... that's getting ahead.  I think the idea of the Atlantic weakness somehow transitively dictating the flow structure and so forth is setting sail ... slowly.  We may need to see a couple runs to gain confidence.. But, particularly in the blend of say, the 00z Euro with the 06z GFS, those runs look more Meteorologically sensible - at least to me.  Which, to be fair...yes it can return... However, the behavior was suspect to begin with, with that odd retrograding 500 mb trough along the 37th parallel being that far N.  interesting..   

Well, we'll see ... but, another run like that and think folks are just being some sort of forcibly contrarian if they don't see the writing on the wall... That's an extended, historic heat event for the country, and merely missing the 850 panache where having to rely on 21 C as opposed to the 24s and 25s may simply be a matter of temporality in the runs.  

As far as Bob's knee-jerk dismissal of heat around his backyard ... He has a climate-based point. But there is a reason for those numbers - which I am sure he is aware, and as you pointed out amply... the entire southern hemisphere of the wind dial makes it very difficult to put up big numbers there because of the big blue heat sink lurking near-by.  However, given the larger scope pattern and what's going on ... anyone in those S. coastal communities ...should the wind go west for any length of time in the early to mid afternoons, you will cook too... That's likely open to less debate -

Seemed like he was talking about a 6-day record heat wave, which you also say may not be a record long heat wave...seems you two are on the same page.

Has ORH ever had a 6-day heat wave?

Might be interesting to look that up... yeah. 

Thing is, I've seen Logan roast to 97 F and ORH is 89 sometimes when that's happened.   So as we know there's a significant difference between 1,000 sigma level and a stone's throw to sea-level during a warm well-mixed atmosphere pointing flags ESE.  But even in those off-shore dandy afternoons...say, WNW under a +18C 850mb with good mixing... places like BED/ASH... FIT ...etc, will be 94 to 96.   Contrasting, there are hot day "types" where it more stagnant...calmer winds in the bowls of a heat dome... and it's 93 (which is getting to top tier for ORH) while ASH flirts with a hundred... 

Anyway, what I'm getting at is that some of the longer stretches of 90 plus in Boston's annuls  ( I recall 9 day stretch of 90 to 93 in I think it was 1988 ... NYC was 13 I think)  Worcester can hold up at 87 the whole way...  Yeah, hard to sustain 90+ that high up when it doesn't have a surrounding land mass to add to heating. 

EDIT, I see Brian already did -

That’s pretty sweet.  Was that at the current location by then?

Nope.  That was set at 620' while the current site is at 986.  However, I found a 6-day in August 1988, 10th-15th, though no days above 93.  Aug. 28-Sept. 2 just missed, spoiled by the 89 on Sept. 1.

To me the worst heat waves are the ones that last a week and both day and night temps are high, usually indicating very humid conditions, here are some of our climo sites warmest 7 day periods ever.

No,, I'm specifically curious why he and others ... are quick to dismiss higher numbers.   I mean I understand the climate argument; excluding that, which does not dictate the discrete events, ...only that it describes the mean, I get the "feeling" that people are basing their notions on "feelings" ... unless there is some physical argument?    ...I dunno.
