[40/70 Benchmark]

High of 96 today after 91 yesterday.....look like will make 4  consecutive of 90+ through Wednesday.

My p&c for tomorrow has a high of 103 with a HI of 111...worst I could find....not the jack I yearn for

One thing to keep in mind is that MWN's all-time record high us 72 set on 8/2/1975 and 6/26/2003.
If the GFS is showing "only" 66, that is of concern for lower elevation max temps fcst.

8/2/1975 was ideal dry NW flow subsidence for highest temps on record in much in New England, and we do not have this pattern currently.  And on 6/26/2003, general 100-103 did not occur in New England.

CoastalWx needs to do something about OWD temps!  Closest ASOS to him, so he has a vested interest!  

And talk about bad sensor or their placement, look at Baltimore/Inner Harbor today.  Site is poorly located (not at an airport) and obviously contaminated by the concrete jungle or something like AC units nearby.  General city UHI is not *that* strong during the day.

Today was an all timer. Spent a good portion of the late afternoon and evening outside documenting it. 

[Prismshine Productions]

keep in mind: between now and this time next month we lose 33 minutes of daylight... going to start to be tough to get heat of this magnitude once we get to that point because a month after that we start looking at cold front intrusions for the interior 

[CoastalWx]

94 for the high at home with an 82 dew. Pretty good considering we flirted with the seabreeze.

What a night.

Interesting. The point-click for MWN has a low of 60F and a high of 68F. Looking at extremes, that low would tie the all-time record high minimum and break the June mark if it held through to the end of the day - which it might not do. With a low on Wednesday morning forecast for 54F, it could drop into the upper 50s before 1 am EDT. I suppose the forecast high of 68F might be consistent with a 66F reading at 18z. But yeah, you’d probably want to see low 70s for maximum heat.

I would’ve felt that way if we had run of the mill dews, but we crushed it. Big numbers deep into Canada.

Dews will drop tomorrow afternoon to try for the hundy. Probably 98 at my thermo.

[vortex95]

Something to keep in mind for the larger pix (video link attached).

ASOS was not really designed for climate data, it's more for aviation.  And for aviation, temp is a secondary priority, compared to ceiling, vis, wind, and altimeter.

And don't get me started about AWOS, esp. for dew points (they run high often and worse as you get in the 60s and higher).  Seen this many times for OK.  Compare the mesonet w/ all the ASOS/AWOS temp/dews, and it is apparent.

Go to OWD airport for the max  effect!

The acatt gang is huddled up tight in their basements dreaming of a wet and dewy Christmas while window panes only grow moister with condensation from endless clouds of sweat and swamp ass! Ya love to see it.

[Prismshine Productions]

temp already below the forecasted low (72.5 vs fcst of 73)... wonder if it hits the upper 60s again or hovers around 70

I don't see any indication DPs hit 80 in eastern MA or anywhere in New England from the standard airport observations.  Highest I could find is 78.  And DPs were lower near the coast from the sea breeze.

I saw above someone reported an 82 dewpoint. I know the dews are high up in the Northeast, but 82 seems excessive. Dews over 80 are infrequent where I live in South Florida (Miami Beach family home, & also coastal North Broward county), and even more rare in San Juan PR where I grew up. They do seem to happen more often lately & most often occur after a midday shower, and only last a short while.

80 here at midnight

nah, just the fact I live in a radpit that always beats the sensor at Keene Airport

Wish I was in a rad pit. All I have in my new second floor apartment is a shitty Ocean State Job Lot AC in the bedroom. 84 degrees in the rest of the place lol. My landlord is so dumb he doesn't have any AC in here so when you step out into the hallway it's like 90 degrees and there's condensation on the walls.

Wrong.  Peak climo for temperatures is 7/20-8/10.   Look at the hottest days in New England history-they’re in that date range usually.  This hot spell is not only extraordinary in magnitude but also how early it is occurring.

Usually in FL, the 80 DPs are confined to immediate coastal areas.

I do not think BOS has ever had a 80 DP.  78 or 79 max.
 

[WxWatcher007]

Yeah there’s a lag between the solstice and peak climo. Same as winter. We wouldn’t expect -15 temps in SNE on December 23, and peak cold climo is around Jan 20-Feb 10.

The worst heat wave on record for the East occurred before this date range in 1911. 
https://en.wikipedia.org/wiki/1911_Eastern_North_America_heat_wave

BOS hit 104 on July 4th.  So is 11 days earlier in 2025 low 100s in BOS really that extraordinary or that early, relatively speaking, esp. since avg temps everywhere are up by "alarming standards" in the last 100+ years?  And add in the UHI effect at many climo sites, and things aren't quite as impressive as they appear.  I would argue this levels things close to equal as to as far as extremes go for the region.

Facts are meaningless w/o context.

Providing historical context is not pushing an agenda.  No wx event should be treated in a vacuum, but that is what done a lot these days, hence everything is "worst ever" or "unprecedented."
