San Diego is weathering high temperatures and monsoonal moisture this week, as heat advisories remain in effect across various inland regions. According to the NWS San Diego, inland valleys are expected to reach into the 90s today, while the Inland Empire could surpass the 100-degree mark. An increase in moisture, however, might introduce a slight chance of showers or thunderstorms, particularly in the mountains and adjacent deserts.
Tuesday's forecast suggests a similar story, with slightly cooler temperatures but increased relative humidity making it feel just as warm. "An abundance of mid-level moisture streaming in over the region tomorrow will allow for an increased chance of thunderstorms," reports the National Weather Service, especially over higher elevations where the probability could reach up to 80 percent. This, coupled with the persistent subtropical ridge.
For San Diegans hoping for respite from the high heat indices, more moderate weather might be on the horizon later this week. The Area Forecast Discussion from the National Weather Service indicates that "a gradual cooling trend" will begin on Wednesday and continue into the weekend. This is due to a flattening ridge and increased onshore flow, which are also expected to dampen storm activity and deepen the marine layer.
The local marine conditions are set to remain unhazardous through Friday, offering a small consolation to those seeking cooler activities. Nonetheless, beachgoers should take heed of elevated surf and high rip current risks in Orange County through this evening, as advised by the National Weather Service. Despite the marine cautions and inland sizzle, the central narrative for San Diego remains its patchy coastal fog and the ebb and flow of its coastal climate, tempering the edges of an otherwise ardent panorama.
On the daily beat of city life, San Diegans can check the 7-day forecast, which points to a subtle variance in conditions; from tonight's slight chance of showers and continued patchy fog into Tuesday morning, to mostly sunny days with highs fluctuating in the low 80s for the remainder of the week.
