Is there any research on the quantifiable UHI at a station like PHL? I ask because in reality - the airport's footprint hasn't really expanded in over 30 years (much to the dismay of locals). PHL isn't DFW or PHX. PHL sits directly adjacent to the John Heinz National Wildlife Refuge and the Delaware River. To the northeast, it's mostly vacant land. And the closest "urbanized" areas, Essington and Eastwick have both seen population declines in the past 30 years. As a matter of fact, Eastwick is a shell of its former self, most of the neighborhood abandoned and reclaimed by nature due to white flight and serious flooding issues. There are certainly macro effects of UHI, one would assume, in which PHL is somewhat well-located to pick up, though not even that ideal given that directly south of PHL the landscape becomes quickly rural and non-urbanized. I guess I am just wondering how much UHI effect at PHL has actually contributed to the temperature increases in the past 30-40 years?

Yeah. Didn't realize how bad it's up North for you guys until I checked the goes.

Yeah, guidance as well as local NWS Forecasts have constantly been too high . Not just to the tune of a couple degrees but, 5-7.

I put down $250 of seed in spring and simply cut when needed. Haven’t cut in a month. Do I wish it was nicer? Yes. Do I want to invest the time and money? No.

Interesting that the model signal is still there but backed off some after being more aggressive yesterday.

Dog days of summah are here.

It’s tough when Canada is having record heat and drought and they keep getting all these lightning strikes. https://www.cbc.ca/news/canada/british-columbia/bc-wildfires-1.7599568 BC’s fire season is surging as the number of active wildfires more than doubled from 61 on Thursday to 134 by Friday morning, according to the B.C. Wildfire Service (BCWS). The service says the surprising increase in fires can be attributed to the more than 35,000 lightning strikes on July 30 and 31 — with even more expected, as severe thunderstorm watches remained in place on Friday for a large swatch of the southern Interior and stretching into locations in the northeast.

It’s the GFS, so take it with a grain of salt.. https://x.com/lockingitin/status/1952375266569064644?s=61

Pretty ugly smoke. Not too bad along the CT shore though.

Shadows look weird when the light is diffused by the smoke like this.

In a stunning departure from the conditions of the summer to date, August has started off on a very cool note nationwide. The PRISM data below is only for the first two days of the month, but yesterday saw similarly impressive cold with a number of record low max temperatures in the south and a few isolated record lows in the eastern US. While I still expect August to finish out above normal for CONUS, this is going to make a new summer national record quite difficult. Will probably take a few days just to return to 1991-2020 means nationally, which means we are likely looking at one of the coolest first weeks of August in a long while. Probably would need an epic heat wave to keep pace with 2021 & 1936, at this point.

I guess instead of cold or warm fronts now, we have smoke fronts.

Here was a post I made elsewhere on 1/7/2018 about it being the coldest 7 days in my area since Jan of 1977: SAV just experienced its coldest 7 consecutive days in 41 years, its first below 32 F week in 28 years, and a tie for its 8th coldest since records started in the 1870s! The longevity of this cold is one for the ages. 10 SAV weeks at or colder than 32 F starting from coldest: - 1/1886 - 12/1917-1/1918 - 2/1895 - 1/1977 & 1/1970 tied - 2/1899 - 1/1887 - 1/2018 & 12/1901 tied - 12/1989 Only 4 of these 10 weeks have occurred during the last 100 years! By the way, the snow & ice remain largely intact in shady areas and we're over 4 days after it ended! I still have one icicle! 1/8/18 edit: Note that this long duration cold occurred despite a +NAO. It was supported by a +PNA/-EPO combo as well as a -AO when averaged out.

Lots of smoke around.. i don't think I've seen it this bad yet this year

2nd worst air quality in the world for Toronto following the smokiest July on record in Winnipeg.

Coc ks man. Coc ks

Nasty day in se nh. Who wanted this and why?

Wait, you live on Long Island?

@dendrite Just watched this and remember you were growing Chestnuts. Apparently there's 4 trees that seem to be blight resistant so there is hope of bringing them back. https://www.ctpublic.org/shows/human-footprint/clip/the-ghost-tree-bringing-back-the-american-chestnut-mzwjuw

Except it does not!! Clearly PHL Airport see below is warming much faster due to the UHI at the airport

Heading to the Andrea tomorrow.

The best fishing around here is during the colder months. April-June and then October through December.
