Weather Discussion for Monday September 11, 2017

Normal high and low temperatures for Sept 11-Sept 18 (high/low)...Redding 90/58, Chico 89/54, Quincy 81/37, Chester 77/36, Susanville 78/43, Grass Valley 81/49, Weaverville 86/42, Mt. Shasta 77/44, Yreka 82/46, Alturas 78/36

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.

Yesterday was the 70th day this year that Redding has been over 100 degrees that breaks the old record of 69 days set in 1967.

The low pressure area off the southern California coast is moving slowly northward.  The low will continue north and then get pushed eastward late Tuesday and Wednesday as a low pressure trough moves into the the Pacific Northwest (see map below).   Clouds will spread northward over our area today and all of the north state will have a chance of showers and thunderstorms tonight and Tuesday.  Wednesday the showers and thunderstorms will be confined to the higher elevations.  Temperatures today will be a little cooler than yesterday with further cooling Tuesday and Wednesday.  Light to moderate southeast to south winds will occur later today and Tuesday. 

The other thing the low pressure trough in the Pacific northwest will do is push the high pressure ridge eastward.  Thursday through the weekend we will have mostly clear skies with temperatures near normal for this time of year.  A strong low pressure trough will reach the coast late Sunday and will bring clouds to the north end of the state late Sunday and Monday with a few light showers possible.
