I'll take Torturing The Data for $1,000 Alex.

Not only that, but they are  using your RF torture chamber.

From NWS State College:

Smoke can filter out shortwave radiation from the sun resulting in cooler days, but is not as effective in absorbing longwave radiation (the smoke particles are too small), so it has less impact on overnight low temps

I know solar shortwave and longwave heat from the earth is not RF but it's all radiation.

Sterling needs to read the discuassion from State College.    Sterling says:

However, smoke from wildfires will likely continue to obscure the sky to some extent. Am not sure what effect this will have on temperatures.  The HRRR (which does forecast smoke) does indicate highs could  be a couple degrees cooler compared to some other models.

As the smoke wanders the planet for about a week it causes global cooling.  But don't tell Andrew from the Post about it.  Don't want to interrupt his thought process.

Pretty thick brownish haze here in Virginia as I drove out to Winchester.  The shadows were definitely muted. Is there a smoke particle RF absorption?  It's about 20-25k feet.

We have peeks of sun in the valley and got 1.27 overnight.  The first real rain for the  month and very welcome.  Hopefully I won't get banned here for saying I like rain on my first post.
