It was orange yesterday. The smoke is so thick right now. Some additional information about all of that:
"To get a sense for how dark it was in CA yesterday, here are solar radiation observations from my backyard weather station for 3 recent days. Much darker than a typical foggy day, and it was effectively sunset ~3 hours too early."
"The orange skies this morning are a result of wildfire smoke in the air. Strong winds over the past few days transported ash from fires in northern California and the Sierra Nevada into the region.
These smoke particles scatter blue light & only allow yellow-orange-red light to reach the surface, causing skies to look orange. If smoke becomes too thick in a certain area, most of the light will be scattered & absorbed before reaching the surface, which may cause dark skies."
"Very little change in the smoke across the SF bay area the next 18 hours."
