Highly unlikely it was in the 90s at 9am. Yeah, it’s an error. I pulled up the climate data from July 1989 for KPIT and it has daily observations for each three hours starting at 1 am Local Standard Time (i.e. 2 am EDT) and it was 74F at 8 am, 89F at 11 am, and 93F at 1 pm. While the 9 am observation wasn’t listed, obviously wasn’t 93F. Looks like there was some weird time offset in the way the data got uploaded to the IEM database.

The 83F reading from 7 am on September 9, 1989 also appears to be erroneous. It was 69F at 5 & 8 on that date. And likewise the 83F from 6 am on June 23, 1989 also appears to be erroneous. Readings from 5 & 8 am were 67 and 66, respectively. Link to comment Share on other sites More sharing options...

So we very likely tied the 7am record less than three weeks ago and broke it today (assuming the 82 at that hour on August 5, 1989 is as invalid as the other readings from that summer).

July 17, 1988 is also a candidate. It was 82F at 5 am and 8 am, 1F cooler than the observations from June 29, 2012 for those hours. I don’t have the hourly observations for 6, 7 or 9.

TimB Posted July 12 Share Posted July 12 Today was the first day where the normals are 83/64, which is the highest they go. They’ll stay at 83/64 until the 28th, then it’s all downhill. Link to comment Share on other sites More sharing options...

Bit of a strange route to 90 at that. 5-min obs of 90 (probably 89) at 2:30, then down to 85 at 2:51, now back up to 89 or 90. Edit: 90 is official on the daily climate report. Actually reached 91 after 5pm. Link to comment Share on other sites More sharing options...

TheClimateChanger Posted July 12 Share Posted July 12 In any event, today was the 10th day of 90+ for the summer. Looks like the next 4 days will do better than 90F, which would put us at 14 90+ on July 16. For the record, the 19th century summer data is absurd. Some of these years, the official summer mean temperature was warmer than D.C. Also, 1875-1900 averaged a ridiculous 29 days of 90+ in the official record. But 1901-1930 had an average of 9 days at the downtown site [which is even weirder when you consider most sites with PORs that long show that to be a warmer period, with hot summers in 1901, 1911, 1919, 1921, 1930]. The 1901-1930 average is actually one fewer than the current 1991-2020 mean. Link to comment Share on other sites More sharing options...

TimB Posted July 15 Share Posted July 15 Up to 91 at PIT. That’s the 13th day of 91 or above so far this season, which is tied for the 6th highest total of 91+ days through today’s date behind only: 1. 1876 (19) 2. 1988 (18, only year at Pittsburgh International with more 91+ days on or before 7/15) 3. 1880 (18) 4. 1881 (15) 5. 1911 (14) and tied with 1966 (13). The magnitude of heat may not be extreme, but the number of days is up there with some of the hottest summers Pittsburgh has ever experienced.
