Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
A strong Pacific jet stream will push a fast-moving cold front southward through San Luis Obispo County early today. This cold front will deliver increasing clouds with a few light rain showers this morning along the northwesterly facing mountain slopes of the Central Coast. It will become mostly clear by this afternoon.
High pressure will build behind this cold front and produce moderate gale-force to fresh gale-force (32 to 46 mph) northwesterly winds this afternoon along the coastline. Wind gusts of 50 mph may develop along some of the more exposed beaches.

Rain and snow will spread southward down the Sierra through the morning. Snow levels will drop to 4,500 feet, although significant snow accumulations are not expected.
On Tuesday and continuing Wednesday, a pattern of gentle to moderate (8 to 18 mph) northeasterly (Santa Lucia) winds will develop during night and morning hours, shifting out of the northwest and increasing to strong to gale-force (25 to 38 mph) levels during the afternoons. This pattern will produce mostly clear skies and warmer temperatures.
Persistently strong to gale-force (25 to 38 mph) northwesterly winds will produce night and morning low clouds, fog and cooler coastal temperatures Thursday and continuing through the weekend. In other words, the classic Central Coast springtime northwesterly winds will return.
Next week should be dry with slightly warmer weather by the middle part of the week.
Moderate gale-force to fresh gale-force (32 to 46 mph) northwesterly winds along the coastline will generate a 10- to 12-foot northwesterly (310-degree deep-water) sea and swell (with a 5- to 15-second period) today.
This northwesterly (310-degree deep-water) sea and swell will decrease to 9 to 11 feet (with a 7- to 11-second period) Tuesday, further lowering to 5 to 7 feet (with a 7- to 17-second period) Wednesday.
An 8- to 10-foot northwesterly (310-degree deep-water) sea and swell (with a 7- to 14-second period) is forecast along our coastline Thursday through Sunday.
Seawater temperatures will range between 49 and 52 degrees through Sunday.
