TheClimateChanger

Not saying it is the case there, but I know NOAA plays fast and loose with some of these normals. Not enough to raise what is "normal" every 10 years... I know in northern Ohio, they just decided to tack on another degree or two above the calculated 30-year means and call that "normal." Not sure if they are piloting new climate normals that are supposed to factor in climate change or what. Very misleading.

Wow, look at these minimum temperature departures! Lots of +5-7s showing up.

Just an incredible torch. I'm not even worried about the rankings. A lot of these have big site discontinuities. But tons of places at +4 - even some +5s and 6s. I didn't even know it was possible to get such big departures in July.

Yeah, just saw that on Twitter/X. Professor Jacobson noted it. So much for all that cooling... although, looking at the actual numbers, it does look to be a little low hanging fruit compared to the weeks before and after.

Boston tied its daily record high minimum temperature of 74F yesterday.

New daily record high for July 14 in the GLSEA database. Prior record for today's date is shown in red trace (2005). The coldest for today's date is highlighted in green (2001).

Checking in on the lake temperatures. Very favorable swimming conditions, with the exception of Superior. Lake Erie looks like its cooking this year.

I must point out that, in a rather shocking turn of events, the proverbial mercury fell to 63F last night shortly before midnight standard time, and continued slipping all the way to 59F, as a northwesterly flow filtered in cooler, drier, but rather filthy air from Canada. This is certainly nothing unusual for the city of Cleveland in July, but it did bring about the end of this streak at 23 consecutive days with a low at or above 65F. Looking at the higher streaks, it's worth pointing out that the official observations didn't move to the airport until June 1, 1941, but records date back to 1938. There was no 27-day streak at the airport in 1938, that's for sure... not even close. And, in 1872, the thermometer was housed in a recessed window on the north side of a building downtown. So, yeah, I don't really think that's comparable to modern measurements. While Cleveland Hopkins International Airport saw the temperature drop to 59F this morning. The observed low at Burke Lakefront Airport was 66F.

This is a good point. In Texas and out west, they are fighting climate change by seeding the hell out of all of their clouds. I don't know why they don't implement a rain depletion program in the east. Like yesterday was a disaster waiting to happen with those slow-moving heavy thunderstorms. Then, it's like - oh no, the subway is flooding... the NJ Turnpike is submerged! I wonder if they could have zapped the clouds with directed electromagnetic energy or laser beams to heat the surrounding atmosphere up, potentially weakening the advancing storm system? Has there been any research into this?

Wow! Hopefully, these superheated lake and sea surface conditions add enough moisture to the atmosphere to keep such high temperatures at bay for the next heat dome!

The all-time record high is 80F, set on July 25, 2011, August 4, 2011, and August 14-16, 1988. I think that could be the next domino to fall.

Looks like the water temperature at the Buffalo crib site (water intake for the city of Buffalo) on Lake Erie reached a scorching 77F this morning, which exceeds the daily record by 1F (continuous record since 1927). Keep in mind, this reading comes from a depth of 30 or 40 feet below the water surface, so the nearshore temperature could be several degrees higher. 139FZUS51 KBUF 151403NSHBUFNearshore Marine ForecastNational Weather Service Buffalo NY1003 AM EDT Tue Jul 15 2025For waters within five nautical miles of shoreWaves are the significant wave height - the average of the highest1/3 of the wave spectrum.

Zooming in a bit.

Sure, 110 in Virginia on July 15, 1954. What a joke. It's 10 degrees warmer than all of its next day neighbors. Absolute rubbish. It was a hot day, absolutely. With some 100s, the second highest reading (also a little suspect, given the nearby 92) was 106. But this 110F reading is absolute fantasy. It's also nowhere near the East Coast, BTW.

Record high minimum of 74F tied at Dulles Airport yesterday. A record high minimum of 69F was tied at Elkins, W. Va. for the second consecutive day. The urban heat contaminated records at DCA and BWI barely register the warmth.

Quick update here. With some additional observations from yesterday now available, it looks like DC-Dulles Airport also tied a record high minimum yesterday.

Looks like it made it down to 68F at Elkins this morning, 2F below the record high minimum set in 1916, so they will end their record high minima streak at 2 days.

Record high minima tied at Bridgeport (73F) and Islip (74F) yesterday. Not even record-breaking rainfall can flush out this unbelievably resilient heat. Elkins, West Virginia also saw a record high minimum tied (69F), while Concord, New Hampshire, Burlington, Vermont, and Beckley, West Virginia, each matched their 2nd warmest low temperature for July 14. Pittsburgh, PA, Charleston, WV, and Huntington, WV all matched their third warmest low for July 14. There would have been additional records, but unfortunately, several places were unable to retain their heat through 1 am EDT.

Bringing the climate perspectives map forward to Friday (with the forecast values), here's where we could be on the summer to date on July 18 as far as rankings are concerned. Guidance is coalescing on some big heat risks as we move later into the month, so there should be plenty of opportunities to improve upon these rankings.

Guidance certainly seems to be coalescing on some more heat risks as we move later into July. One neat feature of the Climate Perspectives map is that it allows for to forecast ahead up to 5 days. Now, I think the forecast is pretty conservative, but regardless, looking ahead to Friday, here's what it could look like for the season to date. Burlington - you could have your hottest summer to date. Concord, 2nd hottest. Hartford, 4th hottest. Blue Hill (Milton) should continue to see 3rd hottest conditions. Islip, NY, Elkins, WV, Beckley, WV, Raleigh-Durham, NC - you could all be in the midst of a record-breaking summer. Top 5s and 10s all over the place, even with some very sucky station threads out in the mix. Looks even better when its focused on minimum temperature, then 1s start popping up all over the place. Even BOS jumps to 3rd place when you look at minima. I guess those local sea breezes aren't doing as much work at night.

Thankfully, the storm held off just long enough for yesterday's 72F record high minimum to hold.

Anecdotally, the atmosphere seems thicker and more "vaporous" than it did decades ago. More Venusian might be a good way to describe it. In my hometown, the normal July minima used to be in the 50s, but now reaching the 50s there is like a big achievement in the month of July. Normal lows from decades ago are now seen as a nice break from the heat. Very weird to see in the absence of any UHI increases. All very bizarre.
