Pittsburgh, PA Fall 2024 Thread

Interesting that 81% of GEFS members have measurable rain Wednesday, but the NWS is rolling with a dry forecast for the entire period. -
Pittsburgh, PA Fall 2024 Thread
TimB replied to TheClimateChanger's topic in Upstate New York/Pennsylvania
I wonder what the record is for most consecutive above normal months at PIT. I know we had that stretch from February 2016-July 2017 where we had 18 straight above normal months, though a few of those would now be considered below normal according to the 1991-2020 normals. -

Pittsburgh, PA Fall 2024 Thread
TimB replied to TheClimateChanger's topic in Upstate New York/Pennsylvania
Interesting to note that of the 10 streaks of 21+ days of zero measurable precip that Pittsburgh has recorded, 9 of them happened at least partially in fall. The only exception happened in May/June 2023. So fall months can be incredibly dry around here, but there’s always tropical remnants to give us hope. -

Was looking at that this morning. There have been entire GFS runs that show exactly zero qpf through 384. Not just a one off, it seems every other run for the past few days has depicted this. I think the over is a safe bet in this scenario, but model runs depicting zero precip for 16 days are incredibly rare around here. -
That streak looks to continue for at least another week, maybe longer. They have recorded exactly two below normal days in that span, both in August but not consecutive. This forum would spontaneously combust if any eastern locale recorded 98 above normal days out of 100.

That said, I can also see the other side, that PA is in a stretch of fantastic early fall weather and fretting over what is or what used to be (perceived or actual) is secondary to the absolutely perfect weather now and for the foreseeable future. You could also make the “who the hell wants to wake up to 25 degrees in August” argument, even if it wasn’t ever that cold imby or yours.

Oh I’m not running away from the intent of my original post, as it’s pretty obvious what I’m getting at and the data bear it out pretty well. I’m a little more concerned that you’re using one rogue day in March almost 40 years ago to refute the fact that fall comes later than it used to.

It used to get into the 20s in Bradford in August (1982 and 1968 also got to 26 and 29 respectively on the same date, so it wasn’t just a one off), and now we’re marveling at mid to upper 30s in early September, which, Blizz is right, are pretty rare these days. 36 on or before September 3 has occurred in: 1958, 1963, 1964, 1965, 1967, 1968, 1969, 1970, 1971, 1972 (yep, that’s 9 years out of 10), 1976, 1979, 1981, 1982, 1984, 1986, 1988, 1992, 1993, 1994, 1997, 1998, 2000, 2001, 2004, and 2009. So break that down into 3 equal periods: 1958-1979: 12 of 22 years got to 36 on or before 9/3 1980-2001: 12 of 22 years got to 36 on or before 9/3 2002-2023: 2 of 22 years (and none of the last 14) got to 36 on or before 9/3 Oh, and your March record high on 3/30/86. It was matched in 2012, a full week earlier in the spring season. (But you knew this.)

It’s not days of yore, when BFD reached a low of 25 on 8/29/86, but it’ll do.

Still sitting in 2nd, just behind 1880 for warmest YTD on record and over a degree ahead of 2012, which was the warmest YTD at the airport through 8/29. Remarkably, we are running almost a full 3 degrees ahead of 2023 through 8/29, which is currently the warmest full year on record at the airport.

Temp at PIT has surged to 93. This is now the first time since 2002 that PIT has hit 92+ four days in a row.

Would think an outside shot tomorrow depending on frontal timing, but unlikely especially with the airport being west. I hope we don’t see 90 in September but it’s hard to rule out.
