In other words, excessive/extreme heat warning criteria have only ever been observed for two hours in Pittsburgh in June, on that day in 1978?
-
If PIT does get to 94 during this heat wave, it’ll be the first time since 1952-1953 that we’ve done it in back to back Junes, and the first time since the questionable records of the 1870s-1880s that we’ve done it 3 out of 4.

You learned something new today. You’re welcome.
-
Yes, I realized that after I posted. Anyway, as @TheClimateChangercan tell you, asos ran warm in the 80s/90s and that almost entirely explains the KMQS thing.

We’ll see how the averages stack up for June. I’ll bet every major observing site in Pennsylvania is above normal when it all shakes out.

Re: your last statement:
-
In before East Nantmeal shows up and says he didn’t hit 80 yesterday.
-
18th year on record with a high of 57 or lower on 5/31 or later. So it’s about a once a decade event. Last was 56 on 6/1/2015.
-
Pretty impressive cold advection today, for temps to slowly fall through the 50s despite precip ending and a few peeks of sun just three weeks from the solstice.
-
Yeah, looking like a -0.1, maybe a -0.2 depending how cold we get by 1am Sunday. Important to note that May has warmed tremendously in recent years and this month would have been decisively above normal according to the 1981-2010 normals.
-
A shame that we’re going to back into a below normal month after such a warm start. Really thought we’d get 23 out of 24 for the 2 year period starting July 2023.
-
If this morning’s low of 69 holds, it’ll be a daily record warm min. Only once has a low of 69 or higher been recorded at PIT on or before May 16th, though there are a handful of other instances in the threaded record.
-
Who’s ready for days and days of cut-off low misery?
-
Might we make a run at 90 tomorrow?
-
The record for most 75+ degree days through the end of April is 15 in 1945. The record since observations moved to the current airport location is 12 in 1960. We’re currently at 7 with a decent shot of up to 7 more before the month is over.
-
To add to that, today is tied for the 7th earliest 86 degree day on record, and is third earliest at PIT. 4/11/1930 4/14/1883 4/16/2002 4/17/1896 4/18/1896 4/18/1976 4/19/1941 4/19/2025
-
Yes, officially the first April morning that hasn’t dropped below 73. If we weren’t getting a cold front today we could have obliterated the record warm low for April.
-
79 on the 10pm hourly obs at PIT. Warmest 10pm temp ever observed in April at PIT. Edit: we also smashed nearly every hourly record overnight. Temp hovered at 76 until 5am and has just now dropped to 73 or 74.
-
That is the coldest max ever recorded in the month of April, and by a full 3 degrees at that. Interestingly, today also claims a tie for the record high for the month of April, with 90 in 1896.
-
Thing passed right over the north hills. My biggest hailstones were around quarter to half dollar size. Reports of up to golf ball.
-
This past weekend was the first time on record that PIT airport didn’t get below 60 for consecutive days in March.
-
Low of 64 so far. If that holds through 1am (possible) it will be the warmest March low ever observed at Pittsburgh International and tied for 2nd in the entire period of record.
-
Officially a high of 81 at PIT. This is the earliest ever 81 on record, just 134 days after we recorded the latest ever 81 on record on 11/5/2024.
-
Looks like we did reach 80. That hourly obs of 80/14 is now officially the lowest relative humidity ever observed at PIT (8%).
