Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
Another weak but cold upper-level low-pressure system is expected to move into the Central Coast on Monday, bringing a few scatted rain showers and a chance for mountain snow down to between 3,000 and 3,500 feet. As with Saturday night’s upper-level low, moisture remains limited, and thus rainfall amounts are expected to be less than a tenth of an inch.
High pressure is forecast to build over California on Tuesday and will remain parked over the West Coast through the remainder of the week. This condition will produce moderate to fresh (13 to 24 mph) Santa Lucia (offshore) winds during the night and morning hours. These winds give clear skies and warmer weather.
Daytime highs will return to near-normal by midweek and slightly above-normal by the end of the week. Because of the cold air mass left in place by Monday’s systems, chilly night and morning temperatures are anticipated into Tuesday night/Wednesday morning with widespread 30s and 40s across the Central Coast, followed by more seasonal temperatures late in the week.
