July 12, 2018
Summary: A great deal of cloudiness covers the southern two-third of California this morning. Most of the clouds are leftovers from thunderstorms over Nevada and the southern Sierra Nevada. We have a very warm bubble of subsiding air above us, indicative of high pressure aloft. The freezing level over Oakland this morning was up to 16,400 feet. The marine layer stands at 1,800 feet, but there’s not enough pressure difference between the off shore waters and Nevada to tug that marine air inland. The winds aloft are currently out of the east and will continue to bring monsoon moisture into central California. Temperature forecasting will be a bit tricky. Areas with a great amount of sunshine will easily eclipse the century mark while cloudier locations should be in the upper 90s to the lower 100s.
By Sunday, a very strong high center is projected to be right over California. The monsoon may be crushed a bit but there will still be at least a chance of thunderstorms over the Sierra Nevada. From Sunday on, temperatures will soar into the 102 to 108 degree range unless heavy cloud cover moves over the area on any given day.
Medium range models are still showing relatively strong high pressure over the western states with a trough east of the Rockies. This will allow hot weather to continue with monsoon moisture rotating in from the southeast from time to time.
Forecast: Variable cloudiness at times through Thursday. Mostly clear to occasionally partly cloudy Friday through Sunday. Partly cloudy Sunday night and at times through Thursday and continued hot.

Two Week Outlook: July 19 through July 25: This model indicates a continuation of persistent upper level high pressure over the Desert Southwest and California. This pattern will favor monsoon moisture moving into our region from time to time for partly cloudy skies. Thunderstorms will also be possible each day over the Sierra Nevada and possibly the Kern County mountains. Temperatures will range above seasonal values.
July: This model is indicating high pressure over the Desert Southwest will be stronger than usual. A fairly active monsoon is also indicated for periods of thunderstorms over the Sierra and hotter than average temperatures over the valley floor.
July, August, September: Like the 30 day outlook, this model is indicating we’ll have a hot summer, moving into the early fall. Above average precipitation is possible over southern California and the Sierra Nevada due to an active monsoon season with temperatures remaining generally above average for the next three months.
Winds: Winds will be generally at or less than 15 MPH through Sunday and mainly out of the northwest afternoons and evenings.
Rain: Expect dry conditions indefinitely
