The last time that happened was June 2nd. Upper 50s looking likely tonight. Brief cooldown with heat returning on Wednesday. 8” of Reddit rain nowhere to be found.

But the airport’s precip deficit for the month will surpass an inch tomorrow. Link to comment Share on other sites More sharing options...
jwilson Posted July 21 Share Posted July 21 I'm guessing rainfall deficits or surpluses are quite localized over the last few weeks. Locally, I think, we've dodged most of the rain, so July has felt quite a bit drier than either May or June here. Link to comment Share on other sites More sharing options...
TimB Posted July 23 Share Posted July 23 With PIT officially dropping to 58 this morning, we avoid tying the record at the airport site for warmest July minimum, which was 59 in 1955. Now back to our regularly scheduled programming of heat, humidity and eventually daily rain chances for the weekend. Link to comment Share on other sites More sharing options...
TheClimateChanger Posted July 24 Share Posted July 24 I don't know what's going on with the airport thermometers this year. It's bizarre. Like all the airports dropped 2-3F, every single one of them? Especially AGC and HLG. They went from one of the warmest spots in the PBZ CWA last July to among the coldest by mean maximum temperature this year? AGC has suddenly become one of the coldest spots in the entire CWA outside of some high mountain sites for daily high temperatures. PIT airport went from 1.7F warmer than the Moon Township COOP in July 2024, to 0.9F colder this July. The lows are still warmer, but they have dropped a bunch too relative to the COOP sites. Last year, 4 airport sites had the warmest daily low temperatures in July. This year, the highest is like 5th of all sites. Link to comment Share on other sites More sharing options...

Last year, 4 airport sites had the warmest daily low temperatures in July. This year, the highest (KPIT) is like 5th of all sites (i.e., 4 non-airport sites have higher mean low temps). Table attached below shows the difference between mean low temperature for 1st 22 days of July 2025 versus mean low temperature for July 2024. 51 sites have data for both years. Missing data not a significant factor, only 7 of the sites have more than 3 days missing through the 1st 22 days of the month. It is a factor for some individual sites, e.g. Pike Island shows an 8.7F increase but had 15 missing days in July 2024. 49 of 51 warmer. Exceptions: Donegal 2NW Coop, bizarrely 3.3F cooler, and DUJ Airport, 0.5F cooler. The mean difference is +3.2F across the 51 sites. 4 of the 6 smallest increases are the airport sites - DUJ (0.5F cooler), AGC (1.0F warmer), MGW (1.4F warmer), and PIT (1.7F warmer). Compared to the mean (average) change across the 51 sites, DUJ is 3.7F cooler, AGC is 2.2F cooler, MGW is 1.8F cooler, and PIT is 1.5F cooler. The smaller airfields seem to be unaffected. AFJ is +5.6 for the year on year (or 2.4F warmer than the mean change) and BTP is +4.1F for the year on year comparison (or 0.9F warmer than the mean change).

TheClimateChanger Posted July 24 Share Posted July 24 I know there was some discussion about PIT and AGC maybe running warm at times last year, but it definitely seems to have been corrected. Arguably running a little on the cool side this year compared to surrounding observations, especially AGC. The official tally might have this July cooler than last, but overall it's been a bit warmer just about everywhere in the region (especially with the overnight minima).

TheClimateChanger Posted July 25 Share Posted July 25 Currently at 8 days at or above 90F for the season at PIT. Looks like generally upper 80s to around 90 through Tuesday. We'll see if we can add some to that tally. Cooler air set to infiltrate late next week, with a milder start to August. I do expect another hot wave at some point in later August.

I do expect another hot wave at some point in later August. Up to 10 days on the year now. Yesterday wound up warmer than expected but still fell 1F short. Next two days look like 90+, and Wednesday should be around 90 as well (depending on cloud cover and showers). Cooler and drier air pushes in on Thursday and lasts through the weekend. Highs over that stretch look like upper 70s to near 80. It doesn't look like anything crazy cold, but it should bring the longest sustained stretch of below normal temps since late May/beginning of June.

TheClimateChanger Posted Tuesday at 03:00 PM Share Posted Tuesday at 03:00 PM Wow! Up to 8th place for the summer to date, hottest since 1934 (observations taken downtown).

The funny thing we were apparently in 7th place yesterday and, despite, blazing heat, dropped a spot. Summer to date nearly 4F above norms... using 1990s-era normals, we'd probably be running a ridiculously insane 5F+ above for the summer. Link to comment Share on other sites More sharing options...
TheClimateChanger Posted Tuesday at 07:42 PM Share Posted Tuesday at 07:42 PM Made it up to 91F today at PIT (so far). 5th day at or above 90F in the last 6 days (only exception, 89F on Sunday). Link to comment Share on other sites More sharing options...

That is the most ever through the end of July, 12th most in an entire summer, and the most in an entire summer at the airport site with still the entirety of August to go. All of the other years with this many 70+ lows occurred with observations taken downtown. 1 Link to comment Share on other sites More sharing options...
TimB Posted Thursday at 12:02 PM Share Posted Thursday at 12:02 PM To add to the above, this July has featured 15 days with lows of 70 or above. The previous most at the airport site was 11 in 2020. Link to comment Share on other sites More sharing options...

The previous most at the airport site was 11 in 2020. Incredible stuff. Up to 9th warmest July overall at Pittsburgh, and 4th warmest since 1901 (excluding the early steroid-era records) behind only 1934, 1921 & 2020. I expect July to come in around 74.3F statewide, which would tie 2011 for 4th hottest (since 1895) for the statewide mean. This is based off of a current statewide (unweighted) mean of 75.4F from 105 well separated climate stations. Gridding/aerial averaging (urban adjustments?) have generally shaved off about 1-1.1F from the simple arithmetic mean in recent years with a similar basket of stations, which would bring us to about 74.3F.

The mean minimum temperature of 68.2F at PIT last month was 0.8F higher than the mean average (avg. of max & min) temperature from 1976, and pretty comparable to the mean average temperature observed in 1960, 1984 & 2000.
