| Area Forecast Discussion National Weather Service San Diego CA 310am PDT Fri Mar 13 2026 Synopsis High pressure will bring near-record heat to inland areas today while the coast begins to cool. Onshore flow on Saturday will bring cooling to below record levels. For next week, high pressure will strengthen with widespread record heat for all but possibly the immediate coast with monthly records for March likely to be set at many locations for the valleys, mountains, and deserts. There will be widespread moderate to locally major heat risk for inland areas next week peaking around Thursday and Friday. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties Short Term - Today Through Friday Weak offshore flow on Thursday is trending weakly onshore. High temperatures for coastal areas are expected to be a few degrees cooler today with the deserts and inland valleys slight warmer and the mountains around 5 degrees warmer. There could once again be several record or near-record high temperatures today, but mostly for the valleys, mountains, and deserts. Onshore flow will strengthen on Saturday with cooling for most areas. The deserts will be a few degrees cooler than today to 8 to 12 degrees cooler for the coast and western valleys. High temperatures on Saturday are expected to range from the upper 60s and lower 70s near the coast to the lower to mid 80s for the inland valleys with the lower deserts in the lower 90s. These high temperatures are around 5 degrees above average near the coast to 10 to 15 degrees above average for the inland valleys, mountains, and deserts, well-above average but not record-setting. Mid and high clouds will spread across the area for late today through late Saturday afternoon. The local WRF is still forecasting a coastal eddy to develop late today. The mid and high clouds are expected to keep any low clouds and fog for coastal areas for tonight into Saturday morning patchy in coverage. The coastal eddy continues for Saturday night into Sunday morning with deepening of the marine layer. Greater coverage of low clouds and fog for coastal areas is expected for Saturday night into Sunday morning with the decrease in higher level moisture. As high pressure aloft begins to strengthen on Sunday, high temperatures are expected to warm around 5 degrees for the coast, valleys, and coastal slopes of the mountains as the marine inversion begins to strengthen and lower. .LONG TERM (Monday through Thursday)...
