That's probably an extreme example, but I believe some progs had it modeled. Here's the 00z 3k NAM from the night before.
Low 70s dews in SNE during the morning and then mixing out into the 60s and pockets of <= 60F in E MA from BYV to BOS where the hottest temps were achieved. We often get that early to mid morning dewpoint bump as the dew evaporates off into the low levels and then come afternoon the deeper mixing allows the drier air back down to the surface. In the evening the surface cools and reaches saturation rapidly so you get the dew formation (countryside) before 2m fully drops to the overnight mins. (I know you know this...just throwing it out to the non-mets)
Here's the number of days per year at CON with 70F+ dewpoints at each hour. There's a clear late morning bump, mid afternoon "min", and then the late evening spike around sunset. Then it continues to radiate, reach saturation, and the T/Td make that slow drop together until sunrise.
Obviously places like BOS or ORH don't radiate well so they tend to stay mixed 24hrs.
Beer? It's July. There's abundant evapotranspiration. We're not pulling 95/45. 95/60 is hot, but nbd compared to some other heat events we've had the last decade where we're 97/75 in the afternoon. Sat and Sun mornings I radiated down into the low to mid 60s. Then you get a little dew bump mid morning as all of that dew evaporates and then the dry air mixes back down once again. DAW was 97(*)/60 at noon yesterday. BOS was 100/57. That's how we always used to run big heat here until the last decade when mid 90s over mid 70s became more common.
Yeah...that's what I meant by the SE. I know it's still been hot with that run of 100s at EWR, but the dews haven't been that bad and the heat hasn't been super exotic...yet. EWR doesn't have a lot of trouble hitting 100F anymore although almost a week straight of it is still impressive.
It's been liking it for awhile and they haven't come to fruition yet. I expect some good heat up there in the LR, but I'm tossing all of those absurd numbers right now. They didn't happen in the SE, they didn't happen in the midwest, and they're probably not happening in Minny...not to that extent anyway. We'll see.
Like I said…I haven’t been following it enough to know if it’s been trending more away from other nearby sites. But when this is your topography around the ASOS anything goes.
EWR stands out many times (110° in 2011 was ridic), but their obs tend to have validity due to their “terrain”. It is what it is. People live in the paved forest so it’s representative to a lot of people.
I don’t think they’ve done a very good job maintaining MADIS in the last couple of years either. No proof on that, but I see a lot of analysis errors when I check my site.
Some of that is going to be the EWR concrete jungle influence giving them higher readings versus surrounding towns with more vegetation. MADIS will almost always think they’re too high. I haven’t followed them enough to get a feel if they’re running higher than normal though. Put up a bunch of U90s in a row down there and EWR will be 100+ on most of those days.
