Forecast

November 19, 2020/report

November 19, 2020

Summary: Considerable amounts of low level moisture is trapped in mainly the southern San Joaquin Valley.  There are two layers of cloud cover.  T he first is upslope clouds generated by a push of west/northwest winds above the valley floor.  Lift over the Kern County mountains is generating some light rain in a few regions over the Tehachapi Mountains.  On the valley floor, Visalia was reporting a visibility of ½ mile, Bakersfield ¼, and Porterville ¾ of a mile with an

overcast base at just 200 feet.  From Fresno County north, skies have generally cleared.

 

Today through Saturday, a zonal flow will set up over the eastern Pacific, extending inland through California.  The main storm track will ride up over the top of this high and into the Pacific Northwest with the trailing portions of these disturbances moving through northern and central California with little fanfare.  In the wake of yesterday’s system, dew points are fairly high on the valley floor, so there will be areas of night and morning fog especially towards the center of the valley.

 

By the middle of next week, the off shore high will begin to build northward and eastward.  It will dominate the pattern through next weekend with somewhat above average daytime temps and above average daytime lows.

 

Forecast:  Fog and low overcast in Tulare, Kings, and Kern Counties with gradual clearing this afternoon.  Mostly clear skies from Fresno County north.  Expect mostly clear to occasionally partly cloudy with variable cloudiness Friday with areas of night and morning                                                                                                                                                                      fog.  Mostly clear Friday night through Thanksgiving with areas of high clouds at times and areas of night and morning fog.

Two Week Outlook:  November 26b through December 2  this model points to a continuation of the pattern we’ve seen in recent weeks.  Storms will move through the Pacific Northwest, clipping northern California from time to time with central California remaining largely dry.  Anticipate somewhat above average temperatures.

 

Winds Discussion:  Winds during the late morning and afternoon hours will be variable to no more than 10 MPH while winds during the night through mid morning hours will be generally at or less than 5 MPH with extended periods of near calm conditions through Sunday.

 

Rain Discussion: Expect dry conditions for the next 7 to possibly 10 days.

 

Frost Discussion:  All locations will be above 32 degrees tonight.  For Friday night through Monday night, widespread readings ranging from 32 to 37 can be anticipated, assuming skies remain relatively clear and the fog doesn’t take over.  The very coldest locations, such as unprotected sink hole type terrain, have the potential to drop to roughly 28 for short durations.  The bottom line is, most locations will remain above freezing.

 

From the middle of next week on, stronger high pressure will take over, putting a cap on the valley floor conducive for night and morning fog.  A slow moderation of overnight lows will begin.

 

Air Quality Expectations: The San Joaquin Valley Air Pollution Control District has issued the following warning(s) for November 19, 2020:
