The first storm of fall will bring cloudy weather to San Luis Obispo County later today and a chance of light rain Wednesday and Thursday, forecasters say.
Today will begin sunny, then clouds will start building up by the afternoon and into the evening, said PG&E meteorologist John Lindsey, who is based at Diablo Canyon nuclear power plant. Today will be slightly cooler than Monday, with highs in the 70s in the North County and 60s elsewhere.
The storm system will slowly work down the West Coast and arrive over the county Wednesday, Lindsey said, producing clouds and drizzle.
“There is also a chance for a few scattered rain showers on Wednesday night into Thursday morning across the Central Coast as this system moves by,” said Lindsey, who has done local forecasting for 25 years. “At this time, rainfall amounts appear to be light, with only a few hundredths of an inch expected, if any rain falls at all.”
Never miss a local story.
More likely, he added, are snow showers at the higher elevations of the Sierra Nevada.
High temperatures countywide Wednesday and Thursday will be in the 60s to low 70s, with overnight lows in the 40s and 50s, the National Weather Service said.
Skies will be partly cloudy Friday before fair and warmer weather return for the weekend, Lindsey said.
