Wouldn’t be shocked if we hit 94 or 95 but upper 90s seems difficult to say the least. There’s a reason we’ve only reached the upper 90s in one of the last 28 years.

I’m hoping for widespread mid to upper 90s next week so you can tell us you topped out at 89.4.

I know the Euro overdoes heat, but it has 97, 94, 99, 96, 98 for the 18z temps Mon-Fri of next week.

Thanks for the reminder about 2004. Only 20 years ago and it’s unfathomable that we could ever go an entire summer without getting above 87, and the entirety of July and August without getting above 86.

The euro’s depiction of this upcoming heatwave is brutal, though it’s still pretty far out. 3 days of highs in the mid to upper 90s and lows in the upper 70s.

Indeed, that is 12 consecutive months. There was that stretch of 18 months from February 2016 through July 2017 above the 1981-2010 normals, but I think a couple of those months are now below the 1991-2020 normals.

To that point, we could get into that extreme heat category as early as next Saturday. Euro and Canadian both have us getting to at least 94 on that day. There are 23 instances in the threaded record of the temperature getting to 94 on or before June 15th, but only two of those were at the airport (6/14/1994 got to 96 in the midst of what is the standard-bearer for mid-June heatwaves in Pittsburgh, and 6/15/1988 got to 94 and I don’t think much more needs to be said about that summer). Still plenty of time for the magnitude and duration of the heat to change, but all indications right now are that full-blown summer is upon us in a week or so.

We’ll see if the upcoming cool period is enough to offset both the above normal first 5 days and the hot period later in week 2 that the ensembles are converging on, or if we get our 12th straight above normal month. If I were a betting man, I’d put money on the latter.

DuBois set a record high today.

Hell of a way to spin a table that shows 5 of the 6 warmest summers have occurred in the past 14 years.

The official report said 56.6, so it’s a tie for warmest.

It appears our spring average temperature got to 56.7, which puts us in sole possession of first place for warmest spring ever in the threaded record.

Looks like we at least tie the record warmest spring. We’re at 56.6 and both today and tomorrow will average slightly above that. 2nd wettest spring behind 1901 has been clinched. 2nd warmest 1/1 through 5/31 behind only 1880. 2nd wettest 1/1 through 5/31 behind only 1890.

No sane person on this earth trusts your data. It’s literally for your own entertainment.

We’re well on our way. PIT has overperformed its way to a high of 75, well above anything that was forecast. So behind a decisive cold front, we’re going to have a day with an above normal low and reaching the normal high. First place is in reach.

Plugging in the forecast for the next 4 days, I come up with an average for the full spring of 56.5. It looks like 1921 had a warm end of May to finish at 56.6, so we might end up 2nd unless we overperform on temps, which we usually do so not out of the question.

If the month ended yesterday, we’d be the 3rd warmest May at Pittsburgh International. But since we have 4 cooler days left in the month, we’ll likely end up 4th. And if we don’t drop below 56 before midnight, it’ll be the 22nd day this month with a low temperature higher than the May 31 normal low of 55. The only year with more was 1896, when records were taken somewhere in the UHI.

3rd place right now for wettest spring on record. Need another 0.1” to pass 1933 for 2nd place, which is still possible. Over an inch behind 1901 so not likely we top the list.

Looks like maybe that airport cell was a hailer. Might we get our official trace of snow for May?

We have to work with the data we have, but if we had data back through 1250 and it still showed a warming trend, you’d ask “bUt WhAt AbOuT bEfOrE 1250?????”

This sounds smart, but isn’t.

Currently the 17th warmest May on record with a very warm stretch coming up the next 3 days. Could reach top 10 by the end of the month (3rd or 4th at PIT) the way it’s looking now. It’s starting to feel like this stretch of obscene warmth that’s been pretty much continuous since winter 2022-23 with a small break last May/June is never going to end.

The word “relatively” is doing some heavy lifting there.

That’s cool and all, but you see, Chesco has spliced his 20 years of records in with 110 years of already existing NWS data, so it basically is NWS data.

I’m sure @TheClimateChanger will have more, but the first 13 days of May were the 24th warmest in the period of record and 8th warmest at KPIT (since 1952). This has been driven by warm lows (7th warmest average low at KPIT for the first 13 days of May, and 18th for the entire period of record).
