San Diego drivers may face slick roads and slower commutes as scattered showers return Sunday and isolated thunderstorms threaten by Monday night.
According to the National Weather Service, cloud cover will thicken Sunday morning with a 30% chance of showers, mainly after 11 a.m. Monday carries another 20% risk of rain with storms possible late at night, which could bring brief downpours, lightning, and gusty winds. Motorists on I-5 and I-805 should prepare for sudden lane spray, reduced visibility, and possible travel delays.
Sunday highs will hold near 77°F under mostly cloudy skies, while lows dip into the upper 60s. By Monday afternoon, clouds will break for partial sun before the late-day storm threat builds. While rain totals remain light, less than a tenth of an inch, even minimal rainfall could snarl evening traffic and disrupt outdoor plans.
Residents should charge devices, avoid unnecessary late-night driving, and watch for lightning risks at the coast and inland valleys. West winds Monday will remain manageable near 10 mph but could gust higher near storm cells.
Conditions improve by Tuesday with partly sunny skies and highs in the upper 70s, though another 20% shower chance lingers early. Sunshine returns solidly by midweek, bringing dry, seasonal weather to close out September’s first full week of fall.
More advisories remain possible if storms strengthen. Drivers and residents should monitor updates through Monday night.
