It's been in the high 90's with ash from the 6 mile wide wildfire in the foothils coming down.
The fire is so hot it's creating its own weather. This afternnon you could see where the heat broke through the inversion layer and created a cumulus cloud of smoke. Same thing you see when the warm desert air comes over the mountains and hits the cooler L.A. basin air, forming thunderheads.
Today's cloud was "man-made"!
