San Diego residents can expect a warm start to the week with temperatures climbing above the seasonal norms, according to the latest forecasts from the National Weather Service San Diego. In the coastal areas, highs of 74 to 82 degrees are expected today, while western valleys and inland Orange County may reach temperatures of 82 to 87 degrees. Inland valleys are projected to heat up to 82 to 90 degrees, and the high deserts are not far behind with a range of 76 to 80 degrees. It’s the low deserts, however, that will bear the brunt of the heat, with highs forecasted to be between 87°F and 92°F, according to the National Weather Service in San Diego.
As Sunday rolls in, areas further inland are expected to experience a temperature increase of 10-15 degrees above the usual, creating a minor to moderate heat risk. Despite the warmth, Sunday is also expected to bring weak Santa Ana winds, creating elevated fire weather conditions for the foothills and eastern valleys in San Diego/Riverside Counties, as well as the Inland Empire. Gusts ranging from 25-40 mph along coastal slopes and through mountain passes are expected, according to the forecast obtained by the National Weather Service.
Meanwhile, meteorologists are keeping a close eye on a shallower marine layer and periods of weak offshore flow. “Low clouds have not spread as far inland, with patches of dense fog on elevated coastal terrain,” the Area Forecast Discussion from the National Weather Service states. It also notes that the high-pressure ridge responsible for the current warm spell will continue to build before starting to fade midweek, making way for a significant drop in temperatures and a rising chance of precipitation by next weekend…
