Forecast

December1, 2021/report

December 1, 2021

Temperatures will be pushing record values today and Thursday. A strong ridge of upper level high pressure covers the eastern Pacific and extends through California and into the Great Basin. The balloon sounding over both Oakland and Vandenberg indicated an easterly flow from ground level through 30,000 feet. A rather stiff pressure gradient is in place at the surface. The current altimeter reading at Salt Lake City is 30.45 inches of mercury, sloping to 30.06 at LAX, which is a moderate Santa Ana wind configuration. Down sloping winds off the Kern County mountains will heat by compression, driving temperatures into the mid to upper 70s in Kern County with low  to  mid 70s  elsewhere.

 

A weak low will develop Thursday off the southern California coast, but it will just meander out there before moving inland into northern Baja Sunday. The high will weaken, giving way to a trough of low pressure moving through northern and central California Monday night and Tuesday. Measurable rain could make it as far south as a Monterey/Merced/Yosemite line, however for the central and south valley no measurable precipitation is expected. A large high will build over the eastern Pacific and into the western ¼ of the US by Wednesday of next week, so the forecast will remain precipitation free indefinitely.

 

Forecast: Mostly clear and hazy through Monday with patchy night and morning fog. Increasing cloudiness Monday night. Variable cloudiness Tuesday and Tuesday night. Becoming mostly clear Wednesday with patchy fog.

Two Week Outlook:  December 9 through December 14: This model shows the storm track moving further south with above average precipitation over northern California and average over central California, so at least we have a shot at some rain. Temperatures will remain above average.

 

December, January, February: If this model is to be believed at all, temperatures will be marginally above average over central California. This model also depicts the main storm track continuing into the Pacific Northwest with somewhat below average precipitation over the southern 2/3 of California.

 

Wind Discussion:  Winds tonight through Friday will be generally variable at no more than 10 MPH with periods of near calm conditions.

 

Rain:  Expect dry conditions for at least the next 7 to 10 days.

Frost: All locations will be above freezing.
