San Diego is bracing for a weather pattern with the National Weather Service (NWS) reporting scattered rain and snow showers will intensify through Monday. According to the NWS Forecast Office in San Diego, there's even a slight chance of thunderstorms rolling in for the coast, valleys, and mountains. As this cold low-pressure system sifts through Southern California, snow levels are anticipated to dip to about 4000 to 4500 feet, setting the stage for potentially impactful snow across various mountain regions.
Gusty southwest winds are expected to weaken gradually, but the temperature drop is noticeable, with highs staying below average across the area. The Area Forecast Discussion indicates that drier and warmer conditions should return by Wednesday, though another low-pressure system could bring even more precipitation next weekend. Meanwhile, snowfall accumulation above 6000 feet in the San Bernardino mountains could reach a staggering 12-18 inches, coupled with snow blanketing areas as low as 3500 feet, affecting travel through places like the Cajon Pass.
Daytime temperatures have taken a notable plunge, with coastal areas barely reaching the 60-degree mark and inland valleys cooling down into the low 50s. The mercury is forecasted to climb closer to seasonal averages by Thursday, but until then, residents might want to keep their warm layers handy. Beyond the dip in the thermometer, preparedness for the coming precipitation is key, as the NWS warns for possible minor flooding in areas where thunderstorms develop and rain rates exceed 0.30 inches per hour.
The winter weather brings more than just a chill on the travel front. The National Weather Service cautions that "snow covered roads may present hazardous driving conditions" and advises checking the latest road conditions for mountainous areas—a reminder of the reality these conditions impose. For the seafaring crowd, mariners expect occasional showers continuing into Tuesday, with potential isolated thunderstorms that could come with gusty winds and lightning. Those by the shore should also be wary, as there's a reported 15% chance of a thunderstorm at beach locations from Sunday afternoon through Monday.
