Weather Discussion for Wednesday July 4, 2018

Normal high and low temperatures for July 2-July 9  (high/low) Redding 98/65, Chico 95/60, Quincy 88/43, Chester 82/44, Susanville 87/49, Grass Valley 86/55, Weaverville 91/48, Mt. Shasta 84/49, Yreka 88/51, Alturas 85/43

This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring.

A cutoff low pressure area has formed off the coast and is currently stationary (see satellite picture below).   This low will slowly move northward Thursday and Friday.   The main effect this low will have on Northern California is to cool temperatures to a few degrees below normal today through Friday.   We will see a few clouds from the system as it lifts northward late Thursday and Friday and there could be isolated thunderstorms over the mountains north and east of the valley.  Gusty south winds will occur this afternoon and Thursday and Friday afternoons.  

Saturday the large high pressure area that is over the U.S. will build back to the west and cover the entire U.S. (see map below).  This will bring a return of hot weather to the north state.  Saturday through at least the mid part of next week the inland areas of the north state will be sunny with above normal temperatures.
