SAN DIEGO — Today and tomorrow will be the warmest days of the week as a ridge of high pressure builds over the west coast.
The marine layer will return each night and morning, with patchy fog possible for the commute. Most areas will clear out by mid-morning but some coastal areas may see some stubborn clouds linger into the afternoon.
A weak disturbance will bring a very slight chance for a pop-up thunderstorm near the mountains Thursday afternoon, though most activity should stay to the north of San Diego.
The marine layer will strengthen into the weekend as a low pressure system approaches. This will act to usher in cooler air and potentially limited clearing on Sunday along with a slight chance for mostly light showers overnight Sunday into Monday morning. As the center of the storm moves through we'll get a chance for a few thunderstorms in the afternoon and evening and since moisture will be limited dry lightning will be a concern.
Gusty winds will target the mountains and deserts as this system moves in over the weekend with temperatures topping out near to just below normal into early next.
