A weak storm will blow in from the Pacific early Thursday and produce scattered showers across most of San Diego County, particularly along the coastal fringe, according to the National Weather Service. Forecasters say the bulk of the rain will fall between 10 a.m. and 1 p.m., and that San Diego could get 0.20 inches of precipitation. “That’s not bad for this time of year,” said Brandt Maxwell, a weather service forecaster. The daytime high will not rise above the mid-60s at the coast, and sharp winds could snap at local beaches during the morning hours. Maxwell said the lighter showers are possible on Friday morning.
