The rumble of thunder was heard in parts of Santa Barbara County's South Coast Thursday afternoon, as a band of showers moved through the area.
National Weather Service forecasters said an upper-level low-pressure system was bringing a 20-percent chance of showers and thunderstorms to the region through the evening.
Doppler radar showed the band of showers over the city of Santa Barbara and adjacent mountains at about 3:30 p.m.
Rain amounts were light — generally less than a tenth of an inch — but stronger storms and heavier rain were possible later in the evening, forecasters said.
Sunny skies were expected Friday into the Memorial Day weekend, with highs in the lower- to mid-70s.
