Motorists are urged to allow extra time and keep headlights on when driving through fog.
According to the National Weather Service, showers and isolated storms remain possible until late Saturday morning, with a 20 percent chance of rain. Conditions improve later Sunday as skies turn mostly sunny and temperatures rise to the low 80s. Winds stay light, but fog will likely return Sunday night, reducing visibility once again.
Saturday night brings lows in the upper 60s with light coastal winds. By Sunday, inland communities such as Escondido and El Cajon could warm into the mid-80s, while the coast holds steady near 81. The cycle of morning fog and afternoon sun continues through midweek, with temperatures remaining seasonably warm.
Travelers heading to the beaches should remain cautious early each morning when dense fog blankets the coast. Those with flights at San Diego International Airport may also see slight delays due to low cloud ceilings during early hours.
The pattern shifts little through Thursday, with mild afternoons, patchy fog at night, and clear conditions by midday. Residents should prepare for slower starts but otherwise enjoy stable, sunny afternoons.
