San Diego residents can expect a diverse range of weather conditions through the week, with temperatures slowly easing back to seasonal averages and a mix of cloudy and sunny skies. According to the National Weather Service San Diego, "Temperatures will be a few degrees cooler in the coastal basin, a few degrees warmer in the lower deserts," suggesting a mild start to the week in the coastal regions, contrasted by persistent warmth in desert areas.

Moreover, there is a slight increase in the chance for additional showers and thunderstorms focused primarily on the mountains and high deserts late Tuesday. The National Weather Service San Diego's Area Forecast Discussion states, "There is a chance of showers for the mountains, deserts, and inland valleys for Tuesday afternoon through Wednesday afternoon along with chance of thunderstorms for Tuesday afternoon and evening and again for Wednesday afternoon."

Inland, the temperatures will gradually cool through Wednesday, with highs a few to around 5 degrees below average, as indicated by the area's forecast discussion. Residents in the Inland Empire can expect mid-70s to lower 80s, with the lower deserts reaching mid to upper 90s. The cooling trend is due to a low-pressure system from the northwest that will deepen the marine layer, resulting in coastal low clouds extending farther inland and onto the lower coastal mountain slopes.

Closer to the coast, daily conditions will include low clouds during the morning hours with gradual clearing, as detailed by the 7 DAY FORECAST SAN DIEGO. Thursday will bring mostly cloudy weather, then gradually becoming sunny, with a similar pattern persisting through the weekend. Despite the early clouds, by the weekend temperatures are expected to leap to around 5 degrees above average, significantly.
