Weather Discussion for Wednesday April 28, 2021

 Normal high/ low temperatures for April 26-May 3 (high/low) Redding 77/50, Chico 76/48, Quincy 68/34, Chester 62/31, Susanville 65/35, Grass Valley 66/42, Weaverville 71/36, Mt. Shasta 64/36, Yreka 68/36, Alturas 63/31

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. 

Ref the question in yesterdays comments...The last 2 year period is the second driest in the past 100 years.  The only drier was 1976-1977, and those of us that were around here remember that.  Any rain now won't help much.  In 1977 we had a wet May and still had a bad fire season and water shortages.  Not sure what the long...long...term weather will be but we should be prepared for a new normal.  From what little I have read I think we will find that the changes in the Arctic ice are more of an influence than we realize.  

The strong high pressure ridge will continue over the west coast through midday Saturday.  Skies will be mostly sunny with a few mid and high clouds at times.  Temperatures will be 12 to 18 degrees above normal and winds will be light.

Last Saturday and Sunday the high pressure ridge will be weakened (see map below) as a low pressure trough rides over it and across Canada and the Pacific Northwest.  Look for a few mid and high clouds Sunday and them mostly sunny through at least the middle of next week.  Gusty north winds will occur late Sunday through midday Wednesday.

There is some indication in the longer range models of a chance of rain late next week.
