Synopsis
Through Thursday, dry and warmer with weaker winds. Cooler for the weekend with a slight chance of showers, mainly for San Diego County from the coast to the mountains, with stronger and gusty west winds for the mountains and deserts. Then dry with warming and weaker winds for early next week.

For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties
Short Term - Today Through Friday
Through Thursday, there will be dry weather and warming with weaker winds. High temperatures today will warm 5 to 10 degrees for inland areas with another few to around 5 degrees of warming for inland areas on Thursday. With the warming, high temperatures will still be a few to around 5 degrees below average on Thursday with Thursday high temperatures ranging from the mid 60s near the coast to the 70s for the Inland Empire with the lower deserts mostly in the lower 90s.

The marine layer is still around 3500 to 4000 feet deep with the most widespread coverage of low clouds on the coastal mountain slopes. The marine layer is expected to become a little shallower for Thursday into Friday with night and morning coastal low clouds extending into portions of the valleys, but mostly not onto the coastal mountain slopes.

Long Term - Saturday through Tuesday
A low pressure system from the northwest moving into the western states for the weekend will bring cooling, deepening of the marine layer, and stronger and gusty west winds for the mountains and deserts. There is also a slight chance of showers for Saturday night, mainly for San Diego County from the coast to the mountains.

High temperatures on Sunday will be as much as 12 to 18 degrees below average for the mountains and inland valleys with Sunday high temperatures ranging from the lower 60s near the coast to the 60s for the Inland Empire with the lower deserts in the mid 70s to lower 80s. The marine layer will deepen enough for night and morning coastal low clouds to extend onto the coastal mountain slopes for the weekend.

Then dry with a warming trend for early next week with Tuesday high temperatures around average for the mountains and deserts and around 4 to 8 degrees above average for the coast and valleys. High temperatures on Tuesday will range from around 70 near the coast to the 80s for the Inland Empire with the lower deserts in the mid to upper 90s.
