A cold front approaches Tuesday, which will be a mild to warm day (cooler South Coast due to wind off water). Rain showers will arrive from the west in the evening, making for a fairly wet night.
Front pushes offshore early Wednesday, which may begin with some showers, as low pressure forms on the front and intensifies while moving away. The balance of the day ends up windy and cooler with breaking clouds. Can’t rule out an additional shower due to some instability.
Thursday will be the brightest day of the week as high pressure moves in from the west, but low pressure to the east will still be close enough to cause a gusty breeze between itself and the approaching high pressure area. It will remain cool.
Late week will see the approach, passage, and departure of a low pressure area, the timing of which remains uncertain. For now, will go for an increase in clouds Friday, wet weather at night, lingering showers into Saturday, then variably cloudy conditions with some lingering threat of showers later Saturday and Sunday. There is conflicting information on whether or not it clears out by next Monday. Will split the difference for now.
