Summary: A very weak zone of upper level low pressure covers southern Nevada and southern California. This feature is adding just enough lift to the atmosphere to allow scattered thunderstorms to percolate over the southern Sierra Nevada and even over the Kern County mountains during the afternoons and evenings. Some debris clouds from these storms drift over the valley from time to time with no active weather. This trough will weaken and dissipate over the next 36 hours, allowing weak high pressure to dominate our weather through the first half of the weekend. Temperatures will peak Sunday as readings top out into the upper 90s then will fall back Monday through Wednesday as a low center moves out of the Gulf of Alaska and into the Pacific Northwest. The marine layer along the coast is actually fairly deep, however, with no significant difference in surface pressure between the coast and the valley floor, any marine impact will be confined to the Delta region. Temperatures Monday through Wednesday will fall back into the mid 80s at most locations, or marginally below average for mid June. Medium range models show yet another low moving to a position off the northern California coast by next weekend which would seem to preclude any chance of triple digits for the near future.
Forecast: Mostly clear skies through Sunday. Mostly clear skies will continue Sunday night through Thursday.

Two Week Outlook: June 21 through June 27 This model indicates the usual dry pattern over California during this time frame. A weak trough of low pressure will remain along the west coast for marginally above average temperatures.
June: Of course, this time of year, 30 and 90 day outlooks are virtually useless as they’re essentially the same every year. Basically light all day and hot and light all night and warm. Essentially for June, near average temperatures and dry..
June, July, August: The 90 day summary outlook is the same this year as it is every year. Generally dry with somewhat above average temperatures. The monsoon season hasn’t begun yet, so we’ll start taking that more seriously down the road.
Wind Discussion: Winds through Saturday will be mainly out of the west to northwest at 8 to 15 mph at times. During the night and early morning hours, winds will be mainly out of the northwest at 5 to 10 mph. Winds Saturday night through Monday will be mainly out of the northwest at 10 to 20 mph at times. Local gusts to near 25 will be possible, mainly during the afternoon through the evening hours.
Rain Discussion: Expect dry conditions for at least the next week.
Mid afternoon dew points: Mid to upper 50s. Kern: Mid to upper 50s.
