As Halloween approaches, the National Weather Service San Diego has forecast a weekend filled with cooler temperatures and potential showers. Saturday seems to be the prime target for rainfall, especially during the afternoon and overnight periods. While the mountain areas brace for a possible half-inch of rain, it's less likely that the deserts will experience significant precipitation.
Temperatures are set to start in the pleasant 50s or 60s in the evening but are expected to plummet into the 40s or 50s by 10 p.m. for the coast, valleys, and deserts. However, those planning to trick or treat in the mountains should wrap up warm, and the thermometer there is predicted to drop from the 40s into a shiver-inducing 30s range as the night progresses.
Complementing the drop in temperature, San Diego County can anticipate breezy west winds, which could add briskness to an already cool day. This comes in hand with the arrival of a trough of low pressure set to induce cooler weather and a chance of showers across the region, as disclosed in an in-depth Area Forecast Discussion published by the NWS.
Post-weekend, early next week shows promise for a drier spell, albeit with slightly warmer temperatures and a bout of Santa Ana winds. The system's timing is somewhat uncertain; some models suggest rain could start as early as Saturday morning, others not until later on Saturday afternoon. According to the marine forecast, boaters should know that the storm system might increase winds and seas Saturday afternoon through late Sunday, particularly around San Clemente Island.
Residents and holiday celebrators are encouraged to stay up-to-date on weather conditions through the weekend. The NWS San Diego advises drivers to exercise caution on potentially wet roadways and watch for updates on the evolving weather scenario.
