A zone of upper level high pressure stretches from the eastern Pacific eastward across California. We are flanked on the eastern rim of the high, putting us under a northwest flow aloft. Strong, gusty winds are occurring over favored locations in the Tehachapi Mountains and especially over the Mojave Desert. This is being generated by strong differences in pressure between the northern California coast and the high deserts. The current barometric pressure at San Francisco is 30.18 inches of mercury while at Las Vegas, the current reading is 29.83. the air aloft continues to warm as the freezing level has now jumped to 12,700 feet. Temperatures on the valley floor will be noticeably warmer today and will be downright hot Thursday through Saturday as record temperatures will no doubt fall. Temperatures will jump into the upper 70s today then mid to upper 80s Wednesday and the mid 90s Thursday. there are changes afoot on model information this morning as a low will develop off the British Columbia coast then dive southward into California Monday and Tuesday. This will result in much cooler and breezy weather early next week with the likelihood of showers over the mountain areas and even a chance of showers over the valley floor, especially Tuesday. Currently, models are in disagreement on the timing of this system, or even if it will rain at all. However, I do believe now a chance of showers needs to be added to the forecast for Monday night and Tuesday.
Forecast: Mostly clear skies through Saturday night. Partly cloudy Sunday. Increasing cloudiness Sunday night. A slight chance of showers Monday afternoon then a chance of showers Monday night through Tuesday afternoon with a slight chance of thunderstorms Tuesday afternoon and evening.

Two Week Outlook: April 11 through April 17: This model is indicating the deepening of what may be a persistent trough of low pressure over and off the west coast. This will result in a chance of showers along with below average temperatures.
April: April is a transition month as we move from springtime weather to early summer weather at the end of the month. This model indicates above average temperatures over the southern half of the Golden State with near average temperatures over northern and central California. Precipitation will range below average.
April, May, June: This model shows above average temperatures over the Desert Southwest, stretching westward to California. With high pressure generally in control, expect below average precipitation…which doesn’t mean much now that we’re headed into the dry season.
Wind Discussion: Winds during the afternoons and evenings will be out of the northwest at 5 to 12 mph through Friday. Winds during the night and morning hours will be variable to around 6 mph with periods of near calm conditions.
Rain: Dry weather will continue through at least Sunday night. A major pattern change will occur early next week, however models are all over the place regarding time, strength, and where and if it will rain. It appears a low will develop west of the British Columbia coast then will dive southward into California, spreading showers and possibly a few thunderstorms Monday afternoon through Tuesday. The GFS model places the center of circulation almost right overhead Tuesday while other models show various positions. For now, the best course of action is to add a chance of showers for Monday afternoon and more especially Monday night and Tuesday.
Frost: Expect above freezing temperatures indefinitely.
