Pittsburgh Summer? 2025

[Ahoff]

Nice and cloudy out there.

[Ahoff]

First official 90 degree day.  92 so far.

I know you guys complain about underperforming temps all the time but fuck this. Its hot and miserable.

[Ahoff]

The temps so far are pretty much spot on.  Looks like 93 so far today per the 5 minute obs.

NWS point and click centered at KPIT has lows at or above 70 every day through Monday. If that happens (I’ll bet it doesn’t), it’ll be the 7th occurrence on record of 9+ consecutive days with lows of 70+, first time at Pittsburgh International, first time since 1918, and the first time in June. Record is 12 in 1916.

86F as of 9:51 am. It might slow down, but you have to think there's at least a chance of a 95F high today. The last official 95F reading was on September 4, 2018, although I do seem to recall some discussion about whether the sensor wasn't running a little hot at the time.

Making a late push on the monthly temperatures. I'm a little skeptical that lows would stay above 70F that entire stretch, especially with showers and thunderstorms becoming increasingly likely. Too easy to drop into the low 70s with rain-cooled air in the evening. At that point, only a few more degrees of overnight cooling gets you into the upper 60s. Taking the NWS point-click values for PIT would yield a final monthly mean of 73.1F. That's 11th warmest in the "official" threaded record but would be the warmest ever at PIT and warmest in the threaded record since 1943. The cold start to the month prevents us from making a run any higher than that. Personally, I suspect that forecast is a little overdone with the increasing rain chances, but we'll see. Definitely going to feel like summertime either way.

The warmest Junes at the current airport site are 1967 (73.0F), 1994 (72.9F), 2024 (72.8F) and 1991 (72.6F). The record is 75.9F in 1934, when observations were taken downtown.

Already have a 90 on the board at PIT. Two degrees above yesterday at the same time, with a dewpoint two degrees lower. I’d say 95 might be in play.

[Ahoff]

Might have stopped at 93 again.  Which is a bit surprising considering we ran ahead of yesterday most of today.  Might still sneak a 94 in the inter obs.

Daily climate report already has high of 94.

[Ahoff]

Yep, temps were forecasted pretty well, maybe a hair under, but not as off as last year’s June heat.  Dew points seemed lower than forecast as well, if only by a little.  Still very hot out there, but more Heat advisory than Extreme Heat warning.

First time since 1885, 1887 and 1888 that Pittsburgh has gotten to 94 in 3 out of 4 consecutive Junes.

Interestingly, those June's lately have outperformed July and August with peak temperatures (last year all three hit 94, but still).  June has generally outperformed August these last few years.  More front loaded summers it seems.

[TimB]

If this morning’s low of 74 holds, it’ll be the first time Pittsburgh International hasn’t dropped below 74 for three consecutive days, and the first in the threaded record since 1930.

Made it to 92 so far today. With clouds & scattered thundershowers, that’s probably as high as it will get today.

Did a surge to 93.  Might be the high today.  With rain coming, I don't think that 74 degree low holds.

What were the monthly averages in April and May? Were they above or below normal? I know Jan and Feb were pretty much lower right?

April above, May slightly lower essentially average.

Another 90 in the bag… 5 straight. That is the longest since an 8-day stretch ending July 10, 2020.

We also had 5 day stretches in both July and August last summer, which I know doesn’t technically negate your statement.

The only other time we had 5 day streaks of 90 degree temps in 3 consecutive summer months (not necessarily the same summer) was July and August of 1887 and June of 1888.

Oh, well, technically off, then. This stretch *matches* the longest since 2020. Honestly, I forgot about those. I thought the June heat wave was 4-day stretch and 5 out of 6 days, but it looks like that hot spell was technically an 89, followed by 2 90s, then another 89, and then 3 90s. And then I guess there were 5-day stretches in both July and August last year, which clearly didn't garner as much publicity as the June heat wave. Granted with the two 89s in the mix, there were likely parts of the area (downtown, some valley locations) that may have seen 7 days in a row but without an official reading.
