The cool reprieve continues in the San Diego area, where temperatures are clinging to a comforting 5-10 degrees below what's typical for mid-August. According to NWS San Diego, locals and visitors alike can expect "another cool day for August standards" today, with an ever-so-slight warm-up on the horizon for Sunday.
A "robust coastal eddy" has hung its hat over the coast, bringing extensive cloud coverage expected to persist through most of the weekend, per the Area Forecast Discussion by the National Weather Service San Diego. A brief respite from the gray will occur late in the morning, but the clouds will stubbornly cling to the coastline into the afternoon. Despite the marine layer's insistence, a high pressure build-up is forecasted next week, warming temperatures closer to their seasonal norms, and reducing marine cloud cover.
Looking ahead, the trend of moderate temperatures is set to shift. By mid-next week, monsoon moisture will return, increasing chances for showers and thunderstorms, particularly over the mountains and high desert areas. The percentages range from a tentative 15 to a more solid 30.
While the next few days promise gentler weather, residents should brace for a temperature surge by the end of the week. These conditions bring the potential for heat risks, especially in inland valleys where "highs in the upper 90s to low 100s" are expected. Overnight lows may also be impacted, elevating humidity levels and affecting comfort. According to the NWS San Diego's forecasts, the "upper high is in a favorable position for monsoon moisture to finally make it into So Cal again," which may result in a mix of high temperatures and increased humidity.
