Weather Discussion for Wednesday September 6, 2017

Normal high and low temperatures for Sept 4-Sept 11 (high/low)...Redding 94/59, Chico 92/56, Quincy 84/38, Chester 81/40, Susanville 82/45, Grass Valley 85/52, Weaverville 89/43, Mt. Shasta 81/44, Yreka 85/46, Alturas 83/38

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.

The low pressure area is still off the coast but is being drawn northward by the low pressure trough and frontal system moving toward Canada. (see satellite picture below).  The remains of the low will move across Northern California late tonight and Thursday.   The good news it that this has weakened the high pressure ridge and pushed it a little eastward.   Today and Thursday the north state will see a few clouds with showers and thunderstorms mainly over the higher elevations with isolated activity in the north valley.  Temperatures today and Thursday will be normal to slightly above.   Light to moderate south to southwest winds will occur in the afternoon.

Friday another weak upper level low pressure area will form off the coast.  This low will drop slowly southward and will be off the Southern California coast by the weekend.  Friday there will still be afternoon and evening thunderstorms over the mountains.  Saturday and Sunday will be sunny and warmer.  Temperatures by the weekend will be 5 to 10 degrees above normal.   

Monday the low will begin to move northward.   Tuesday and Wednesday we will see the shower and thunderstorm activity increase across all of the north state.
