A considerable amount of monsoonal moisture is working through just north of a weak upper air disturbance located just north of San Diego. Doppler radar indicates a considerable amount of shower activity is over and off the southern California coast. Models project the disturbance will move northwestward through central California. There is a chance of sprinkles or scattered light showers moving through the valley through Tuesday morning. if there is enough breaks in the cloud deck to allow significant daytime heating to break through, it would destabilize the atmosphere even more, increasing the chance of storms over the mountain areas and even on the valley floor.
The bulk of this this moisture will move just to our north Tuesday morning with a massive high stretching from the Mississippi Valley to off over the California coast Wednesday through next weekend will be characterized by triple digit temperatures each afternoon with daily afternoon and evening thunderstorms.
Forecast: Variable cloudiness through Tuesday morning with a chance of sprinkles or scattered light showers. Isolated thunderstorms will also be possible later this afternoon into Tuesday morning. Clearing Tuesday afternoon. Mostly clear Tuesday night through Monday with occasional high clouds and continued hot.

Two Week Outlook: August 2 through August 8: this model has changed a great deal and now shows the monsoon from being blocked into Mexico with dry weather for a change over the Desert Southwest and southern California. Temperatures will remain above average.
July: The 30 day outlook for July follows the trend set in June with above average temperatures and upper level high pressure that’s stronger than usual. The typical dry conditions will continue.
July, August, September: Above average temperatures can be expected for the next three months. This model is given equal chance of rain for not only California but also the parched desert southwest.
Winds Discussion: Winds during the afternoon and early evening will be mainly out of the northwest at around 5 to 12 MPH. Winds during the night and morning hours will be variable to around 10 MPH with periods of near calm conditions.
Rain: Doppler radar depicts fairly widespread light shower activity over much of southern California, including coastal valleys and off shore. Models show this activity beginning to bend towards the northwest later today, increasing the chance sprinkles or light showers if significant breaks occur in the cloudy cover they would increase the chance of shower activity over the mountain areas with a small chance on the valley floor. Rainfall amounts from now through midday Tuesday will generally range from nothing to upwards of .10. It’s not out of the realm of possibility for a heavy shower or activity over the valley floor, especially late this afternoon and tonight as that upper low tracks north/northwest just to our west. The vast majority of monsoon moisture will move into northern California Tuesday afternoon, returning dry weather to he valley. Dry and hot weather will continue Tuesday night through the weekend with a slight chance of thunderstorms over the foothills Friday and Saturday afternoon.
