Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
Gentle to moderate (8 to 18 mph) Santa Lucia (offshore) winds should produce mostly clear skies throughout the Central Coast on Monday morning. Monday’s high temperatures will range among the high 90s in the North County, the mid-80s in the coastal valleys and 70s along the beaches. Fresh to strong (19 to 31 mph) northwesterly along the coastline Monday afternoon will keep the coastal regions from getting to warm.
The marine layer will return to the coastline by Tuesday morning. However, hot inland weather is forecast Tuesday into Wednesday as high pressure strengthens across the Western U.S. A large range in temperatures for the Central Coast is anticipated, with triple-digit readings in the North County, high 80s in the coastal valleys and 60s along the coast.
Little change or slightly cooler conditions will then develop toward the latter half of the week, with a chance for monsoonal moisture to creep into the Central Coast from the south. Details are still unclear regarding the moisture, but if it does pan out, it could result in muggy but cooler daytime conditions, mild overnight lows and a chance for scattered convective showers and isolated thunderstorms. This condition could increase fire danger, with the possibility of new wildfire ignitions caused by lightning.
