As a powerful weather system moves in, the San Diego region braces for a shift towards cooler temperatures, high winds, and the potential for significant rainfall.La Mesa TodayAfter an unusually hot stretch in March and early April, San Diego County is set to experience a gradual cooling trend this week, with temperatures falling 3 to 6 degrees in many areas and up to 10 degrees in coastal communities. A stronger weather system is forecast to move in on Thursday, bringing high winds to the mountains and deserts, as well as a chance of showers throughout the county from Friday through Sunday, with the highest chance on Saturday.
Why it matters
The upcoming weather pattern represents a significant shift from the recent record-breaking temperatures and elevated fire danger fueled by Santa Ana winds. The cooler temperatures and potential rainfall could provide some relief to the region and help mitigate wildfire risk.
The details
Temperatures are expected to rise slightly on Wednesday, making it the warmest day of the week. However, by Thursday, a stronger weather system is forecast to move into Southern California, ushering in a sustained cooling trend through the weekend. High winds are expected to develop in the mountains and deserts beginning on Thursday, and there is a chance of showers throughout the county from Friday through Sunday, with the highest chance on Saturday. Rainfall totals remain uncertain, but forecasts indicate many areas could receive moderate rain, with some models suggesting a roughly 30% chance of a half-inch or more for the coastal areas, 40% for inland valleys, and 60% for the mountains.
