Forecast

December 7, 2020/pm update

Summary: The center of circulation of the upper low which crossed over the south valley earlier today is now west of the Channel Islands off the southern California coast.  All the cloud cover from this system has now moved into southern California and off shore.  As the low crossed the Sierra Nevada this morning, some impressive wind gusts were recorded.  Mount Tom in the Sierra National Forest recorded a peak gust of 51 MPH, Bear Peak 54 MPH, and the Mammoth Mt. Summit 90 MPH.  Currently, the winds aloft over the southern half of California are out of the east, wrapping around the low off the south coast.

 

The low will position off the northern Baja coast later tonight into Wednesday then will get pushed eastward by a weak trough of low pressure moving through the Pacific Northwest and then into the Great Basin.  Following this system will be a series of Pacific storms which will move into the Pacific Northwest and parts of northern California Friday through Sunday.  The flow aloft over central California will be out of the northwest, which is onshore for a change.

 

No rain is anticipated, however models from the 15 and beyond are looking more favorable for the chance of Pacific storms moving across the northern half of the state.

 

Forecast:  Mostly clear skies through Thursday.  Mostly clear to occasionally partly cloudy Thursday night through Sunday.  Increasing cloudiness Monday.

Winds: Winds through Thursday during the late morning and afternoon hours will be variable to no more than 10 MPH.  During the night and early morning hours, winds will be generally less than 5 MPH with extended periods of near calm conditions.

 

Rain:  Expect dry weather tonight and for at least the next 7 to possibly 10 days.

 

Frost:  Dew points this afternoon are running in the low to mid 30s.  interestingly enough, dew points over the valley portion of Kern County are up between 7 to 10 degrees and are also in the low to mid 30s.  temperatures this afternoon are roughly 2 to 4 degrees cooler than 24 hours ago, but are still approaching the low 60s at  most locations.  We are now down to 9 hours and 43 minutes of daylight, so with the long December nights, and generally cloudless skies, strong radiational cooling will drop temperatures below freezing for at least a couple more nights.

 

It’s possible we may begin to see some cloud cover from disturbances moving inland to our north Friday through Sunday.  However, where skies remain mostly clear, below freezing conditions will continue.

 

We just might get a break next week as medium range models continue to trend towards a pattern that would bring at least a chance of rain over northern California from Tuesday through Wednesday.  For tonight, the coldest unprotected river bottom and similar locations will drop down to 24 to 25 with most flatland locations between 26 and 30.

 

Most locations in Kern County will drop into the low to mid 30s.  Hillsides in all areas will be above freezing.

 

The inversion tonight will begin to tighten up during the early morning hours with temperatures at 34 feet running from 4 to 8 degrees warmer at most locations.  Expect similar conditions Wednesday and Thursday mornings.
