Weather Discussion for Wednesday July 26, 2017

Normal high and low temperatures for July 24-July 31 (high/low)...Redding 100/67, Chico 97/61, Quincy 91/45, Chester 88/47, Susanville 90/52, Grass Valley 90/58, Weaverville 97/50, Mt. Shasta 89/52, Yreka 94/54, Alturas 90/46

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 weak upper level low pressure area that has been off the coast is now dissipating as it moves eastward and hits the large high pressure area that continues over the western U.S.  Today the north state will be mostly sunny with afternoon cumulus clouds over the mountains with a chance of showers and thunderstorms over Siskiyou, Modoc, and Lassen counties.  Temperatures will be about like yesterdays. 

Thursday through at least the mid part of next week a strong high pressure ridge will be...once again...over the western U.S. (see map below).   This means a return of temperatures 6 to 12 degrees above normal.   One thing to note....on this morning's satellite picture (below) you see 2 hurricanes in the southeastern Pacific.   These storms will be weakening and moving northward over the next several days.  Some of this moisture could reach northern California Sunday or Monday and trigger more mountains thunderstorms.
