October 29, 2020
Summary: The weather from this point on for the next week to ten days will be very tranquil with pleasant afternoons and chilly nights. It was cold again last night as many ag stations dipped into the mid to upper 30s. Reedley was the coldest location I could find at 33 degrees. At the upper levels of the atmosphere, a layer of warm air above the valley floor is becoming evident. As of 6:00am, Sandburg at an elevation of 4,100 feet was reporting a balmy 62 degrees while Blue Canyon at 5,600 feet came in at 59. This is a classic warm air inversion above the valley floor. Readings in the low to possibly mid 80s will be widespread into next week.
The main player is now an upper level high pressure system just off the northern California coast which now covers most of the western U.S. There is a benign upper air feature off the southern California coast which will move inland over the weekend, but with little fanfare.
The high will flatten out over the Pacific Northwest next Tuesday, weakening the high a bit for a minor cooling trend. However, I don’t see any chance of rain through at least the first week of November and probably longer.
Forecast: Clear skies through Monday. Mostly clear Monday night through Thursday

Two Week Outlook: November 5 through November 11: This model flips us back into more of an amplified pattern with high pressure over the west and a colder trough east of the Rockies. Therefore, rain appears unlikely during this period with a return to above average temperatures.
October: This model essentially depicts the entire lower 48 with above average temperatures over the next 30 days. The most pronounced temperature anomalies will be over the Desert Southwest. This model also suggests there will be an equal chance of above or below average precipitation.
October, November, December: This model reflects the influence of La Nina. It paints above average temperatures over much of the country, especially the Desert southwest, and to a lesser extent, central California. Drier than average conditions are anticipated over southern California while northern California could possibly luck out with near average rainfall. Above average precipitation is expected over the Pacific Northwest.
Winds Discussion: Winds will be generally at or less than 10 MPH and variable during the day. Winds during the night and morning hours will be generally less than 5 MPH with periods of near calm conditions through Sunday.
Rain Discussion: Expect dry conditions for at least the next 7 to 10 days.
Air Quality Expectations: With the tremendous amount of smoke over the valley floor, the San Joaquin Valley Air Pollution Control District has issued the following warning(s) for October 29, 2020:
Today’s air quality is listed as moderate for the entire valley with the exception of Kings County. The air quality in Kings County is deemed unhealthy for sensitive groups.
The District’s Real-time Air Advisory Network (RAAN) can be used to track air quality at any Valley location by visiting myRAAN.com. The option to use a specific address is available.
