Not sure…there’s a seabreeze threat Monday, but that shouldn’t affect the interior much. I’m still on the 97-99 with 70s dews train unless I see more widespread 850s around 24C. MEX has been consistently 95-98 in the hot spots Tue. I want to see something more exotic aloft. I’ve seen these 2m shenanigans before.

Yeah me too in spots. Can never get them all up . It’s infuriating

DTW is located in Romulus, MI. Areas near the airport range from suburban to even semi-rural. Though I currently work from home, from 2015-2021 I had a job where my commute involved passing the airport daily. I became WELL versed in how the temps work (I would pass just south of the airport and then get on the freeway which would drive right past then north of the airport). Temps just south of the airport are an Ann Arbor like bowl of extreme radiational cooling. Talking a quarter mile south of where the airport ends (intersection of Eureka & Middlebelt Rd). I saw this on a daily basis, often passing by at 730am, and the most extreme example I saw was on Feb 20, 2015 when my car read -22F at this spot but the official DTW low was -13F. For whatever reason, the temp always reads lower on the south side of the airport than the north side (where ASOS is). The temps at DTW would consistently come up on the high end of what was reported nearby, but certainly within range. UHI is certainly a factor in big cities, but I feel its more of an "airport heat island effect" at many of the big airports. DTW has grown into a huge airport with numerous runway additions and expansions, the most recent being 2019-20. Even though the ASOS is in a well protected area, theres almost certainly a slight impact from all the nearby concrete runways, especially since the more rural and wooded areas less than a mile outside the airport property run slightly cooler 24/7. I dont feel its a major issue as long as the NWS keeps the thermometer properly calibrated, nor do I feel they should be taking temps in the microclimate of cold readings just south of the airport (as thats not representative). I simply want temps to be representative of what the nearby area is, and with most major sites being at airports its just how it goes. Snow is measured just off site at a park area...would be interesting if there was a thermometer there to compare. Once we get away from DTW to the north and west, there are big elevation difference and some more alternating of bustling areas mixed with rural mixing bowls of raditaional cooling. And then to the northeast is a marine influence. So there are so many variables at play. As long as readings are accurate, thats all I ask for. For instance, with this heat coming, id rather set a record high of 100F with dews in the 60s rather than have it be 93 with a dew of 75. But mother nature makes the call.

I've turned a few on to those up here and they love them.

Haha tell me about it. Normally we wouldn’t go out on a day like that but we had some friends in town from Alaska who really wanted to go on the boat. What’s nice about that long stretch of river is if you have RadarScope and a weather nerd on board you can pretty easily outrun any storms. But generally speaking, we wouldn’t typically be messing around in such conditions.

Euro's been having increased run to run variability on details with this week. still, the ens are about at the ceiling for the means. I'm wondering if this doesn't have an extra special sauce with it and the models might or might not even see it - Oper Euro looks lagged/too cool on Monday - may be a mixing issue

Upton issued Extreme Heat Watch issued for most of the area, eastern Suffolk is left out. Is that different for an Excessive Heat Watch/Warning? Or did they just change the terminology? NWS has 100 forecasted for Mon and Tues. At least point and click in the Bx, a lot of Queens

All these advisories for heat and here you have winter advisories in Montana and Idaho

Still out but they say somewhere between 4-11 it will be restored. Kemp Mill and Takoma Park got hit really hard

MCS exiting Maine is classic backdoor scenario. Heat in jeopardy?

Euro has almost all of NYC and interior LI at 107° Tue. It looks overdone to me given the 850s. Looks like a lot of MU90s with a hundy here and there.

Definitely need a good canopy cleanse.

This is what I mean by a wetter atmosphere. From my own personal observations, it's made it harder to reach or exceed 100 and especially to get higher than 102 especially in the city and at the coast. Even without a seabreeze. In all our big heatwaves, like in 1993 and 1999, even in 2010 and 2011, I've seen clouds billow up as the temperature reached 100 or when it got into the lower 100s. Even on W or NW flow this tends to cut off the temperature rise. During the 30s, 40s, 50s, 60s, I deduce in our very hot summers there was less in the way of clouds and thats how NYC hit 106 in 1936 and how JFK hit 104 and LGA hit 107 in 1966. I know that 1966 was our driest year on record and no other year was even close.

Apparently, Erick beat the record for earliest-landfalling major hurricane in Mexico. And specifically, it beat the record for earliest-landfalling major on Mexico’s pacific coast by over two months! The next earliest was…August 26.

It's much more logical to assume we needed lower heights to reach 100+ in the 30s, 40s, 50s, 60s, because the air was much drier back then. We got a taste of that in 2010.....

YES, 1936 redux!!

wild, so 2 99s in 1949, one in June and one in August, and one 98 in July Tony? and did the 3 100+ in a row in 1948 at JFK and NYC both happen in August Tony?

12z Euro AI still focuses highest heat over NJ intsead of sweeping it to the beaches. It also has a seabreeze for Monday.

Oh I know.. Keep expectations low and hope for a surprise..A metaphor for life in general I suppose

After a few mows they all seem to die off

Yes, I cant wait!!

I can definitely see low 100s in the favored areas Monday and Tuesday... maybe Wednesday too

I liked your idea of a feeble kind of onshore wind unable to really cool beach/shore roads down much below 87 or so, while the baseball fields just inland have EMTs hauling heat victims away... (well, you didn't say that but I'm havin fun with it ) This could also be a great way to draw sharks closer to the Atlantic side swimmers, huh.
