TimB

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%).

Current obs of 79/16 at PIT. 9% relative humidity. Lowest relative humidity ever observed on a 4pm obs at PIT. If you throw out the 6% at 10am on 7/29/96, which is definitely erroneous, this is now tied for the 2nd lowest relative humidity ever observed at any hour at PIT, behind just the 6pm obs on 3/30/07. I looked at the unrounded csv file and it’s actually a hair lower than the other 9% obs.

Also, Tuesday 3/11 through Sunday 3/16 is the earliest in a calendar year we’ve ever had 6 straight 70 degree days. Previous earliest was 3/13-23/2012.

Sounds like Latrobe gusted to 89 during the storms yesterday. https://x.com/NWSPittsburgh/status/1901611673460375904

The only days that have been at or above 79 this early in the season are 3/8/2000 (80), 3/11/1876 (80), and 3/14/1990 (79). Was hoping we could squeeze out a couple more degrees and follow up our latest 81 ever recorded last November with our earliest 81 ever recorded, but it wasn’t to be.

Really that lake streamer the weekend before Christmas that dropped 1” at the airport and 4-6” in the north hills would have put us pretty damn close to normal. Some of us might be already pushing 40” in our backyards.

Along those lines, we are now at 1091 days and counting with 3.3” of snow or less, and obviously very likely to add at least 250 more days to that streak. Previous record was 1015, from 2/20/1972 to 11/30/1974. That is the only other time we’ve gone two consecutive winters (let alone three) without recording 3.4” or more on a single day.

The craziest part of this is, today is now officially the snowiest calendar day of this winter.

And it’s gone.

It’s probably more accurate to measure every inch that falls, regardless of when it melts. We don’t measure rain every 6 hours to give it time to evaporate, do we?

It’s largely been a winter that has looked, felt, and behaved like winter. Not particularly cold, not particularly snowy, but consistently cold and snowy. A large number of days with snow in the air and a large number of days with snow on the ground.

A bit cherry picked, as we’ll have lows above freezing next week, but the only day in 2025 that PIT has had a low above freezing was 1/31. This will be the only calendar year on record that has had 53 out of 54 lows <= 32 from 1/1 through 2/23.

Plausible deniability. Since the temp/precip obs are taken at the airport and the snowfall measurement is done at the NWS office a few miles away, it’s possible that there was no measurable snow at the office between 7pm and midnight.
