"It's called 'summer'..."--CFACT policy analyst Meanwhile from Météo-France: The recent heatwave saw France record, on a national basis, three highest daily mean temperatures, four highest mean high temperatures, and four highest mean low temperatures on record. "Summer" doesn't describe this extraordinary climate change-driven heat. The reality from France: A warmer baseline climate makes hot patterns hotter. Key points from a recent World Weather Attribution rapid analysis: Across large parts of Western Europe, June is warming faster than any other month. In addition, daily maximum temperatures are warming faster than night time temperatures, though both are warming much faster than global warming. The hottest daily temperatures are warming at about triple the rate of global warming and night time temperatures at about twice the rate. Many capital cities are experiencing not only their hottest June 3-day period but also the hottest three-day period since 1950, according to the ERA5 dataset. However, due to global warming, these very high temperatures are now expected regularly during the summer months in many capitals. This means that a similar heatwave in June would have been about 3.5°C cooler during the day in 1976 and about 2°C cooler in 2003. The nighttime temperatures would have been about 2.4°C cooler in June 1976 and about 1.3°C cooler in June 2003. This June 2026 heatwave occurred under a circulation pattern broadly similar to historical analogues – Southerly Flow. However, a similar circulation pattern now produces significantly hotter temperatures than it did in the mid-20th century because the climate baseline has warmed. Key Points: 1) The heat was record-setting, not typical summer warmth 2) Human induced climate change contributed to the extreme nature of the heat 3) Interest-driven policy analysts are poor sources of weather/climate information; they seek to advance their employers' interests and some even resort to pushing misleading information to undermine public knowledge e.g., the flippant dismissal of the heat as "summer."

It usually is not. I'm trying to change that here at UMD. I consider myself somewhat of a Meteorologist Metrologist myself. Though I'm always humbled by those NIST people.

https://weather.cod.edu/satrad/ looping that ... it may also evap a little when it poors over the ridge lines. I guess that times about 2 pm, so the damage may be done S-E of HFD-MHT for temp wrt to cloud troubles. Have to see on that too - Heat's like this... it's a tedious ferreting to find the way it's going to fail.

Trade Alonso...are you serious? I hope you're not. We just signed him for 5 years, biggest FA signing in 2 decades--that is not happening, man lol I mean do you know how dumb that would look? Not to mention the message it sends to future star FAs of his caliber we wanna go after? "Yeah we made a big 5-year commitment to you but now half a season in...bye-bye!" Nah dude this particular take is not it, lol Now Cowser and Mayo, Ward and possibly Rogers I can see.

Going to end up with convective cloud debris today too and may even see convection begin to pop early afternoon...or maybe closer to mid-afternoon. Pretty healthy looking convective complex (at least from satellite presentation) in Quebec racing southeast

Good catch! That might explain the Euro's being a little blunted. DP handling and timing is going to be factor-able.

Found a pic from that day. May 24, 2010

Today might be an interesting test as we head into this anomaly scenario. As an entrance/threshold cross ... the most guidance stall T rises to the 87-89 range, but there are a couple ...such as the GFS, have 90-92. The test may only mean how well the guidance 2-m products ( which I hate anyway - ) are going to handle. But it "might" also be some sort of non-Markovian suggestion of how well we are environmentally materializing the virtual modeling. interesting.. It's complex though. It could also be micro-physical processes that more or less alter responsiveness ... It matters if we're at the ceiling and scratching to lift.

Beaten to the punch. Anyway...big dews here tomorrow afternoon on the 3k. I think this limits the mixing potential tomorrow which may be why highs are toned down a sliver Wed compared to Thu/Fri.

Yeah I followed that up ..it may have 68 to 70F in that range now that I think back a little harder.

can see how the lack of rain in central DE has led to dews at least 10 degrees lower than surrounding areas

06z GFS/Euro try to keep the upper 90s to 100° through Sunday, 7/5.

72F is the record high...only done in 1975 and 2003.

It may have actually been 70 F but yeah.

84 feels like 90 at 945am on the coolest day of the heat wave.

If Derechoes happen, widespread 100s, and some places will get to 105, on Thursday and Friday. Remember in 2012, when this area got widespread 100 and DC got to 105 after the Derecho.

Interestingly, according to AI/the internet 72 F is the record high. I was curious what it was as we were up top one day in 2009 (maybe?) and it was stunningly beautiful, 68 F and still some snow piles in the parking lot. Got some pics of it around here somewhere.

I recall back in my UML days ... 72 F(~21 C) on the rock pile was a useful metric/threshold for hundo at Logan in WNW classic transport heat scenarios. Not sure if this true over all and SW flow types, but I don't see why not ... provided any south coastal oceanic contamination doesn't take place. Preferable to keep the winds less backed that 240 deg (260 down near Scott...) etc

No guarantee it gets that hot down here (Ft Worth) this summer.

Yup

Welcome! Great story, I love all things Pine Creek related ha.

GRR is at -1.4° below normal heading into the final day.

Corona, Queens is one of the prime spots for compressional heating.

What if I told you that the coldest CONUS winter in the 21st century happened during a strong el nino year? And we did it with Nino 1+2 being close to neutral? But for there to be a cold winter in the Northeast or mid-Atlantic in a strong or super el nino, one would think the record warmth would be centered on the PNW or even southwest Canada (like in 2009-10, when record warm temperatures affected the Winter Olympics in Vancouver). Yeah, the only time a robust el nino held for two years was 1986-88, and that el nino dissipated quickly in the 2nd year, setting up the stage for one of the strongest la ninas on record in 1988-89. Prior to the mid-2010s el nino, it was almost a certainty that a strong or super el nino was followed by a strong la nina starting from 1972-73: 1973 - Yes 1983 - No (but we did get a multiple-year la nina, which peaked in the high weak/low moderate) 1988 - Yes 1992 - No (but a major volcano happened, and that might have screwed things up) 1998 - Yes, multi-year strong la nina 2010 - Yes Of course, 2016 and 2024 weren't followed by a strong la nina. Do we think it will happen 3 times in a row that we don't get a strong la nina after a robust el nino?

Yeah, big heat coming. We are now under an Extreme Heat Watch (formerly 'Excessive Heat Watch') for Thursday morning through at least Friday evening.
