High pressure will keep it warm and dry again today. Smoke from wildfires will keep it hazy. Air quality could improve a little on Thursday, but the rest of the haze will get scoured out by a storm this weekend. A strong cold front will move in Saturday night. By Sunday it'll be cold and wet across Northern Utah and SW Wyoming. It'll likely stay dry in the south, but temperatures will get a lot cooler.
