Day 15: Another chance for Central heat rebuild, with maybe some expansion into Texas, as coasts stay mostly relatively cooler.
You can clearly see the epicenter of the wild fires in this animation if you look in the NW part of the video

or the still frame
Looks like our area is worse tomorrow as well.
Dense smoke plume arrives tomorrow.

The latest HRRR shows some absolutely insane smoke on Thursday across WNY. If it comes to fruition it would be much worse than what we experienced a few years ago in 2023.
I can certainly see that too. Maybe a couple of degrees cooler would be possible. Never hit the forecasted high here today. Tomorrow's HRR smoke forecast is even worse, but I have not looked at the latest update.
That would be cool. Still looks active starting Saturday and continuing a while afterwards. We cool off and then maybe another heatwave early August looking at model clusters.
Meanwhile, I believe I bserve smoke overhead. Skies are milky white.
