San Diegans looking forward to a reprieve from the usual heat will welcome the National Weather Service's latest report that temperatures are expected to cool down this weekend. According to NWS San Diego, conditions on Saturday and Sunday are set to bring slightly below-normal temperatures in coastal areas and valleys, with "breezy west winds on Sunday." Despite a cooler weekend, a warming trend is forecasted to step up the heat early next week, with Tuesday's temperatures climbing to 5 to 15 degrees above normal.
The temporary relief from the heat will give way to gusty conditions, specifically affecting the mountains and deserts. The areas can expect "wind gusts 25-35 mph," while "wind-prone mountain passes" could see gusts up to 45 mph, as reported by NWS San Diego. The marine layer, meanwhile, is predicted to deepen, potentially pushing low clouds and fog into western valleys.
Looking ahead to the new week, a high-pressure system is set to assert itself, with forecast models showing a consensus on warmer and drier weather to come. "High pressure aloof and periods of weak offshore flow will bring warmer conditions through next week," according to Area Forecast Discussion. Wednesday is slated to be the week's hotspot, with temperatures in inland valleys feeling the heat up to 15 degrees above the usual.
For those navigating the skies, the marine layer could affect visibility across the coastal terrain and inland valleys. The NWS San Diego has stated, "Vis reductions (1-5SM) are expected for elevated coastal terrain and inland valleys," presenting a note of caution for early morning travelers. Yet, the forecast looks clear for mariners, as "no hazardous marine conditions are expected through Tuesday," a sigh of relief for those planning ventures out on the water.
