From this range you assume the standard corrections.    As Scott was saying, the NW flow is likely to offset - this appears to be ( at this time...) trying to take a S/W plateau slab of desert kinetic air and sending over top.  This is not initially a Bermuda/Gulf delivery.  99/63-ish more so than 89/76.  The other aspect that I think Brian hit on is that normal model magnification may normalize some.  A standard heat wave is still going to be a score for modeling and recognition from this range.

We'll see how things evolve in guidance

I will say though that the ensemble means of all 3 remain impressively amplified, above 594 circumvallate 500 mb ... in fact, it's not even clear it ends but really just loses coherence by virtue of normal member meandering way out in time - there's still arguably vestiges of it there beyond 300 hours.

Abbreviated translation…… hotter and humid than he’ll summer coming for the next 3 months with no breaks.

So I guess we've reduced the pixel counts/allowance on the site?    graphics are being rejected ...ones not particularly expensive either. 

This is a truncated CFS solution from 12z centered on 204.  I thought it interesting to note that this model's climate fusion with the operational GFS is still bursting through that weight and putting this enormous positive anomaly integral fro Colorado to NS

While I think it’ll be hot, I’m still skeptical of a long duration “big heat” wave—big heat defined as 95°+ temperatures or 100°+ heat indices. 

Too early to go big ... responsibly, anyway.  

It's tricky though because ginormous events have a real statistical proven ability to "show up" early and establish themselves in guidance with relative persistence ... compared to say, a big bomb in the winter that comes and goes in the guidance...only to verify as a pedestrian winter storm.   

Heat is very fragile in the guidance.  That's problematic - early detection of historic heat is not really so statistically clad.  As I was pointing out earlier, these so -called "synergistic heat events" - codified that way in attribution science related to CC ...etc. - were not seen in the same way prior to their occurrence.  The reason for that difference is that they are non-linear - they emerge within the on-going signal.  The analogy to "rogue wave" in a choppy sea really does work well.  We can predict the stormy sea, we cannot tell if that stormy sea will synergize.  In other word, unless we unpack the quantum manifold that excludes time in such a way that all possibilities are known, ...we ain't forecasting Pac NW anytime soon.   We can only see the warm pattern. 

When I see that pattern like that...  I agree, let's get the pattern definite.  

The other aspect is that I don't think the eastern OV up through NE has ever seen a synergistic heat event.  It's not a region conducive to that non-linearity.   There are places in the ocean where rogue waves are more apt to occur, for example.  I'm under the impression that as the analog goes, we are not as heat prone here.  Those that hate heat and see 101 on the thermometer would probably rage that we do heat just fine, but Heathrow AP up at London, put up a 105 in 2022, at a latitude 5 degrees N of Caribou Maine.   Relative to their climatology, that is a whopper SD larger than anything Boston has seen.   That was a patented SHE  ...   An equivalent temperature at Boston is ~ 112 

If the megalopolis from PHL to BOS 2-meter hover T'ed a 112 some fateful afternoon, particularly after it'd been 100 for a couple of stressed out bonker days of it already, ah-heh.    right.

As an after thought the 80F in some Febs and Marches over the last 20 years may qualify … but part of climatology is the time of year.  There may be circumstantial limitations (physically) that prevent really truly gaudy I-95 buck.10s that aren’t there in the earlier spring

Poor Wintersnow in CT.

I was born and raised in this kind of weather. I'll be fine! :thumbsup: 

(Just kidding. It was only like 72 degrees outside and once the sun came out I was suffering. I know you all like to make fun of me, but I think the low heat tolerance is probably medication related, and yes, I'm talking to my doctor about getting off of said medication).

Dr Mary Jane can help you.

I looked her up and found a GYN that specializes in menopause. Now come on, I'm not that old yet! :unsure:

And then I realized you might be referring to slang instead and I looked that up and... uh. No thanks. I can't stand the smell of that stuff!
