A trough of low pressure brought rain showers overnight to San Diego. The showers broke up throughout the morning, resulting in light rain and drizzle ahead of a clear and mild afternoon.
For commuters, roads will be wet, so it’s recommended to leave extra time to get to your destination and slow down. San Diego County mountains and valleys received the most rainfall, with several areas receiving more than a half-inch of rain, the NWS said.
By the afternoon, skies will be mostly clear and temperatures will be mild, although still slightly below average.
Sunday marks the vernal equinox, which is the first official day of spring. On this day, as sunlight enters the atmosphere, the atmosphere bends it. As a result, the sun is visible before it rises and you’ll also be able to see it after it sets.

Weak to moderate Santa Ana winds will develop Sunday and prevail through mid-week, the National Weather Service said. A Wind Advisory has been extended through 8 p.m. for the deserts and mountains.
A substantial pattern shift may occur early next week with the approach and passage of a midlevel ridge, causing temperatures to soar 10 to 15 degrees above seasonal averages through the middle of the week while offshore flow simultaneously strengthens.
The ridge was forecast to break down next weekend as a large upper trough takes shape over the eastern Pacific off the West Coast, leading to slow cooling as onshore winds make a return.
Drier air was expected to spread over the region from north to south Sunday through Monday as winds turn northerly with gusty conditions along the coastal mountain slopes, forecasters said.
