San Diegans should brace themselves for another bout of afternoon and early evening thunderstorms today. These will primarily hit the mountains and deserts, where strong gusty winds and locally heavy rainfall are on the cards. According to NWS San Diego, there will be a decreasing chance of thunderstorms on Wednesday and reduced monsoonal moisture.
However, as the remnants of Tropical Storm Juliette become entwined with our weather patterns, Thursday might not let us off so easily. Scattered showers and isolated thunderstorms could sprout up, mainly in the southeastern half of Southern California. Amidst these tempestuous times, our mountains and deserts remain the most susceptible to nature's unpredictable temper.
Transitioning into the weekend, we can expect a shift towards warmer and drier conditions beginning Friday and continuing through Sunday. "High temperatures on Sunday will range from the mid 70s to lower 80s near the coast to the 90s to around 100 for the Inland Empire with 106 to 110 for the lower deserts," cites the report from NWS San Diego. The marine layer, dancing at 1200 to 1500 feet deep, will bring night and morning low clouds over the coastal waters, which will spill into coastal areas each night.
For those with their eyes to the skies, aviation conditions will include low cloud and fog coverage until around 13Z, with visibilities reduced to 3-5SM along the inland edge of the cloud. Spotters in the mountains and deserts should watch for isolated showers and thunderstorms after 18Z, with potential for gusty winds and erratic lightning strikes, as NWS San Diego indicates. While sailors can take a deep breath with no hazardous marine conditions expected through Saturday, residents should remain vigilant and report significant weather conditions. However, Skywarn activation has not been requested.
