A line of thunderstorms has developed ahead of our incoming storm Friday evening.  This line is a little east of Gridley, and stretches northward to near Oroville and Paradise.  Another complex is developing in eastern Tehama county near Vina.  These storms are moving northward, and redeveloping in the places they've moved out of... a 'training' effect.  The main threat will be heavy rain and pea-sized hail, along with dangerous lightning.  This activity should diminish once the rain from the main storm arrives, which should be near Midnight.
