(CBS SF) -- Clouds visible in Thursday's sunrise signal a change in the forecast with muggier conditions and a chance for thunderstorms across Northern California.
Mid-level altocumulus and stratus clouds clouds typically preempt rain, thunderstorms and cooler temperatures on the way.
Meanwhile, subtropical moisture to the south signals muggier conditions will pick up on Thursday.

Although storms could bring cooler weather, lightning could threaten the efforts of crews battling the toughest of several wildfires burning across Northern California on
