Morgantown did later go through its own heat island period for a time in the next decade, where it flipped the script and became a powerhouse of 90 degree days. In 1893, at the height of its ascent, it surpassed Pittsburgh by a whopping 35 days in that metric!

On the topic of 90 degree days, that 19th century Pittsburgh heat island must have been insane. Why so many more than Morgantown? Wow! According to this, from 1880-1882, Pittsburgh had 105 days at or above 90F, while Morgantown had either 8 or 4, with only a handful of missing days?

Some isolated thunderstorms are possible today! Barring a surprise, 90 looks likely today, and low 90s look increasingly likely for both days this weekend. Friday and Monday, it looks unlikely, but close enough that a small change in the forecast could allow us to reach 90F on one of those days. With the current forecast, we could be up to 18 days of 90+ by Sunday. Can we reach 20? Believe it or not, the last time there were two consecutive years with 20 or more days of 90+ in Pittsburgh was 1933 & 1934 (when observations were downtown). There were 21 days in both 1933 & 1934, so it barely accomplished that feat. 1987 & 1988 was very close. Of course, 1988 had tons of 90F heat, with 1987 finishing with 19 days.

Some of the more notable high temperatures reported by ACIS for the Pine Tree State, include: 99 at the Houlton Band of Maliseet Indians Tribal Soil and Climate Analysis Network station, 98 at Augusta State Airport and Dixfield, 97 at Fryeburg and Millinocket, and 96 at Bangor. Among co-coops reporting in the morning (attributed to the following day - i.e., today), Topsfield 2 reached 98 and Van Buren 2 topped out at 95. The 99F reading at the HBMI TSCAN site matches the highest temperature reported by ACIS for the month of August in the State of Maine since 2002. The last time it reached 99F (as per ACIS data) in the state of Maine during the month of August was on August 12, 2016 at Portland Jetport Airport. The last time it reached 100F+ was August 15, 2002, when it topped out at 101F at Livermore Falls 1 E. Fryeburg topped out at 100F on the day prior (August 14, 2002). Above is a partial listing of all highs >92F for August 11, with all of the late reporting data below.

Some very impressive highs across the "Empire State" including 96 at Dansville, 95 at Massena, 95 at Ogdensburg, 94 at Fort Drum, 93 at Fulton and Syracuse. The Miramichi, NB reading was 37.6C BTW, or 99.68F (basically 100F if you use typical American temperature rounding)!

The last time this feat was met was July 6-8, 2010!

Wow, 95F at Augusta, Maine!

That was @canderson post. I haven't posted in here in a while, specifically because of the trolling.

I'm not. @pasnownutwas giving me a hardtime about not posting the record lows, so I just quoted them to point out they were already posted.

They were already posted before I noted them?

Like I said, the record lows were already shared. I shared a record high that happened yesterday. Why would I post about record lows that happened over a week ago and were already shared?

1.5F below the record high daily mean, which was 83.5F set on June 19, 2024. Prior to that date, the record had been 82.5F.

It was 96 on June 19, 2020 & June 19, 2024. I missed the other 96F from 2020 because it only lists the most recent on the "calendar day summary." Interestingly, that same day (June 19) has matched the all-time record at CAR twice in the 2020s.

The haves and the have nots. When will this heat spill south and east out of northern New England and Upstate New York? It's like an impenetrable wall.

Yesterday was the 14th day at or above 90F at PIT this year. The point-click forecast suggests the possibility of as many as 4 more over the next week (forecast highs of 91 today, 90 tomorrow, 90 on Saturday & Sunday). Either way, should be a fairly warm to hot stretch which will likely eliminate the current monthly temperature deficiency.

The average high temperature at Buffalo has averaged 1.5F warmer than New York City (Central Park) for the first 10 days of August. Looking at historical records dating back to 1873 (153 years), I can find only 7 years where Buffalo was warmer for average high temperature for the first 10 days of August: 2025 (+1.5), 2021 (+2.5), 2016 (+3.4), 1959 (+1.8), 1947 (+5.9!), 1911 (+0.1), 1887 (+2.6). Based on 1991-2020 climate normals, Buffalo should be 4.5F cooler than New York City for mean high temperature over the first 10 days of August. The 153-year mean difference is slightly higher, with New York averaging 5.1F warmer. Oddly, over the last 10 years (2016-2025), the difference between the two locations has averaged only 2.0F, with 3 of the 7 cases noted above occurring in that 10-year stretch. Not sure if there's a problem with the sensor at Central Park, but certainly a strange discrepancy from the historical norms.

Yes, those were noted in this thread.

Record high of 86 yesterday at Bradford.

Will be interesting to see how high it can get at Caribou, Maine. Point-click forecast has 94, 1F shy of August monthly record and 2F shy of the all-time record set most recently on June 19 of last year, and previously on June 29, 1944 & May 22, 1977.

Very impressive drought since July 1.

Fortunately, the heaviest rain this morning appears to be missing MKE and the city, but additional rain is still likely.

Sounds like you dodged a bullet there. Wow.

Looks like MKE finished with 6.69” of rain. More heavy rain moving in - maybe a 10” two-day total?
