Weather Discussion for Monday August 13, 2018

Normal high and low temperatures for Aug 13-Aug 20  (high/low) Redding 97/62, Chico 94/58, Quincy 88/41, Chester 84/44, Susanville 87/49, Grass Valley 87/55, Weaverville 94/47, Mt. Shasta 85/49, Yreka 90/51, Alturas 87/41

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.

Once again not much change for the next week.   High pressure will remain over the western U.S. (see map below).   Skies will be sunny...smoky in some areas...and temperatures will be a few degrees above normal.  Winds will be south to southwest in the afternoons.

The one feature to watch is the subtropical moisture that has been moving northward.   Today through Wednesday there will be afternoon cumulus over the mountains.  Tuesday and Wednesday there is a chance of isolated afternoon and evening thunderstorms over the higher elevations north and east of the valley.

Long range models show the high pressure ridge holding through the first week of September.  They continue to show a shift to a fall like pattern in mid September.
