San Diego residents are in for a medley of weather conditions over the next week. According to NWS San Diego, cooler temperatures will prevail west of the mountains today, with highs dropping 5-10 degrees below normal inland. The deserts will see little change, maintaining their typically warmer climates.
On Saturday, the area is set to experience continued cooling as a trough of low pressure moves inland across California. This is expected to bring about a return to near-normal temperatures across the entire region. However, as an area forecast from the National Weather Service mentions, the cooler weather will be accompanied by "breezy west winds in the mountains and deserts. "
Come Sunday, you can expect a return of warmth with highs slated to be 3-7 degrees above normal. However, the progression of these temperature patterns is not set in stone as "a trough of low pressure moving south over the western United States may bring stronger Santa Ana Winds Tuesday through Thursday of next week," indicative of a notably dynamic atmospheric landscape.
Moreover, aviation operations may encounter impediments as dense fog is expected to persist along the coastline through the morning. The NWS forecast discussion warns of "Very low stratus with bases 100-300ft MSL" that have reduced visibility along the coasts to less than 1 SM. A Dense Fog Advisory is in effect for Orange County Coastal Areas and San Diego County Coastal Areas until 10 AM PST this morning, making travel potentially hazardous.
Fire weather concerns heighten during the week, with the NWS forecasting a "high chance of stronger Santa Ana winds Tuesday and especially Wednesday." Gusts could exceed 40 mph, escalating to 60 mph or greater in wind-prone passes and canyons. Tuesday's relative humidity forecasts are uncertain, complicating potential fire weather conditions. By Wednesday, drier air and increased winds could increase critical fire weather conditions, underpinning the complexity and variability inherent to Southern California's meteorological tapestry.
