His last post sealed the deal. Seemed like bait, but thats classic tblizz

You're welcome.

At least it’s helping wash in the fert.

No they just want to hide inside and fast forward to seeing lows moving into BGM. Will never understand.

Loving the strong petrichor smell today. Something about it reminds me of days gone by. *sigh*

The idea of tree and/or vegetation modulation on heat is again water vapor related. There's also a component of straight shade helping to block the sun. These two factors are important in that whole idea. Vegetation "sweats." It's called transpiration when it sources from from plants. Water evaporates from that source, and that lowers the temperature. Although that does add water to the atmosphere in the form of vapor, but you'll end up with slightly elevated DPs in the vicinity of vegetation, with slightly lowered temps. As that is ongoing, the cooler resulting air is drawn downward because of course cooler air is denser. This principle is illustrated well in the bottom photo - although I can't attest to those actual numbers, but in so far as getting the point across.. that's the idea there. Contrasting, the upper photo doesn't have this process. This is a local cooling effect, however. The temperatures in those respective schematics are in the micro meteorology. Which, per course ... what one experiences in a city/urban setting on a hot day is in fact within a micro-meteorological realm. That would be neighborhood vs neighborhood... Unless the given cityscape is pervasively and comprehensively forested and so forth, it calls into questions the efficacy of offsetting a UHI effects. The collection of sun-exposed concrete surfaces, such as downtown, parking lots... the edifices of the buildings too, to mention the heat output from industrial scaled AC exhaust. It's a tricky math. Lot of summing multiple separate integrals in that calculus. My personal belief is that the UHI capacity goes up with warming CC, and goes back down with cooling CC. I suspect the growth may not be entirely linear ( as is going up together ) either. Because different materials have different storing capacitance ... so that changes the contribution into the "UHI bubble" based on different energy source and sinks. It's a coupling of material sciences with atmospheric science, which is not likely trivial. But intuitively, doesn't seem like that's a swift calculation to make.

Just like winter, Tblizz bitches and now a wall of water moving his way.

This is what ACATT COC k wanted. You get rid of HHH and you’re left with cold rains. Shut ins, that sit and look out window at cold rain in summer. When that’s all they do all winter . I’ll never, ever understand it

That’s not what’s happening though.

Not everybody's idea of a nice August day but honestly I'm loving it. Done with heat and humidity. Ready to move on.

The polewood outflow channel is interacting with the Cold front enhancing rainfall. Training rains as tropical moisture advects north will lead to very heavy rainfall rates. PRE

It’s chilly and dreary enough today that I’m breaking out the hoodie. Pretty crazy for mid August.

What we have been talking about in graphics.

Made it to 63° here +1

One knows, the other does not know.

Not much change at all in the Atlantic the last month @Stormchaserchuck1….

Thank you

So far a high of 69. A rare August day staying in the 60s?

up to .38 which doubles my monthly total plus .03

Been thundering here for last 30-40 minutes, waiting for the water.... currently 82.0/71.1 at 3:15 pm.

Ok, well, I don't believe that. It's not 10C (18F!) warmer in a sunny neighborhood versus a shady one if the thermometer is properly sheltered or aspirated. My car thermometer doesn't register anywhere near that difference and it's housed like a foot or so above the asphalt.

Nah NoP.

Record low high temp at ORH is 60. On the hourly we seem likely to break it but probably on the 5 min data it'll end up a tie, barring some late brief spike

I'm actually growing more and more optimistic by the week for this winter. Small positives adding up like QBO, N ATL SSTA, negative ENSO anomalies concentrating east of 140W....still super early and seasonal forecasting is still super high variance, but I'd rather have small positives in our favor than not.

There were a couple folks on here that said that several times. Not sure who they are but they are very fine folks. Big credit to them.
