Currently projecting the Pennsylvania statewide average temperature for July to come in around 74.3F on NCEI, which would tie 2011 for 4th place. I would assess an error margin of about 0.5F to that, which would place this year between 2nd place and 9th place.

Don, a break in the heat may be coming, but it does look like there's the potential for air quality concerns. Will have to wait & see if this eventually spreads into the northeast as we head into the weekend.

Nice pics, and a good reminder that the climate is always changing... just usually a little slower than these days. I remarked recently on the irony of having the Great Lakes exist in a future hothouse earth, carved from that same ice just 14,000 years ago.

Boston down to a chilly 78F. Even colder than Hyannis (87F), Plymouth (90F) and Martha's Vineyard (81F). No chance MeteoMark would go into a pool in those conditions.

2012 saw a similar pattern to those years:

Made it up to 91F today at PIT (so far). 5th day at or above 90F in the last 6 days (only exception, 89F on Sunday).

I'm guessing the clouds from which it was falling were blocked by terrain from the observer's view point? The clouds may have dissipated or moved out of view while the snow was still drifting to the ground, I suppose.

Wow! Scorcher today in Chester County, even in these carefully curated cool microclimates. That's a big pet peeve of mine... why spend all of this money on a "mesonet" and then place all of the equipment on farms or in parks, rather than in the communities where people live and work.

Coming on the heels of the infamous "Hard Winter" of 1880-1881, snow in September... folks must have really been battening down the hatches for a brutal winter. Only to have the rugged completely pulled out from under them. The Long Winter of 1880/81 in: Bulletin of the American Meteorological Society Volume 101 Issue 6 (2020) Hard Winter of 1880–81 - Wikipedia

One thing that's interesting about 1881, September was blazing hot in the east, but there was a bunch of snow in the west. Flurries in St. Vincent and Moorhead, Minnesota on the 4th - yes, just 4 days out of August! A swath of 4-6 inches of snow from Iowa to Minnesota on the 16th. Cheyenne, Wyoming even performed the remarkable feat of a 15-minute snow shower from a cloudless sky on the 29th. It was even so cold in Texas and Oklahoma (then known as Indian Territory) that a ton of cattle died. This is unthinkable in September.

Any thoughts on what went wrong to keep the historic heat away? Looking at the overall rankings (projected through the end of the month), certainly very high compared to the entire period of record. But, in the year 2025, I wouldn't call this historic. If this were 2000, maybe. But looking under the hood, even the very highly ranked sites are only running in line with recent years... E.g., Burlington is forecast to finish 6th since 1884, yet it's only the 5th hottest July in the last 7 years, leading me to believe that, in the current regime, it was actually a rather cool July?

Newark is on a bay. But I'm talking about Syracuse, Albany, Burlington, Vermont, and Scranton, Pennsylvania, not the midwest. Annual maximum has trended up at all of those locations since 1990, as has number of 90+ days (by a significant margin). And that's despite any bias that may have been occasioned by the use of the HO-83 at the beginning of this period. You'll note most sites show a big dropoff in 90F days around 1996 with the installation of ASOS, but have since trended continuously upwards. Annual Maximum: 90+ Days:

I think it was localized to the urban heat island. Inland areas weren't that hot.

Those were pretty hot years, but not close to recent years in most places in the eastern US. Also, the first three were unequivocally inflated at the first-order sites due to the defective HO-83 thermometer commonly in use during that era.

The funny thing we were apparently in 7th place yesterday and, despite, blazing heat, dropped a spot. Summer to date nearly 4F above norms... using 1990s-era normals, we'd probably be running a ridiculously insane 5F+ above for the summer.

Not much talk about it, but we are well within striking distance of a RECORD-BREAKING hot summer nationally. Should be around +2.4 to 2.5 for June & July. The record for JJA is around +2.6F, set in 1936 & 2021. A hot August could push us over the top. Just incredible stuff. I remember growing up in the 1990s, and those heat records for 1934 & 1936 just seemed completely unattainable. Not even 1988 or 1995 could come close. Then, 2012 happened and it was just like one domino after another falling. By around 2040, I'd reckon every single summer will be hotter than 1936, and a hot summer could be something similar to what @csnavywxhas posited.

Wow! Up to 8th place for the summer to date, hottest since 1934 (observations taken downtown). Certainly going to be climbing up this list the next couple of days before cooler temperatures return by Thursday.

Extreme volcanic venting in the north Pacific and all over the oceans! This is wild, you guys!

It's just summer... in the 2020s, anyways. Actually, only 4th warmest of past 6 years so this is probably a relatively cool summer for Harrisburg in this era.

ABSOLUTELY LOVE that setup!

Yesterday was the 5th record high minimum this month at Elkins, West Virginia (71F). This morning's low of 69F will also tie the record high minimum, so that will increase to 6 daily record high minima this month there! Unreal.
