Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
This morning’s Santa Lucia (offshore) winds will keep the low clouds out to sea, but a few mid- to high-level clouds will continue to stream over the Central Coast. Mostly clear skies and low relative humidity will produce cold temperatures in the North County this morning with some of the wind-protected valleys reaching near the freezing level. Along the beaches and in the coastal valleys, low temperatures will range between the high 40s and low 50s. Today’s high temperatures will reach the low to upper 70s throughout San Luis Obispo County.
An approaching low-pressure system will bring increasing marine low clouds with pockets of mist and drizzle tonight into Tuesday. The associated cold front will move through San Luis Obispo County on Wednesday with increasing southerly winds and rain showers. Scattered rain showers will continue through Thursday morning, followed by increasing northwesterly winds, partly cloudy skies and cooler temperatures Thursday afternoon into Friday. Total rainfall amounts should range between 0.10 and 0.33 inches.
Another chance for rain showers will develop Saturday as a series of low-pressure systems traverse Northern California. There will be another chance for precipitation early next week. Overall, none of these weather systems will likely produce heavy rain, but should create light to moderate precipitation at times.
Today’s 3- to 4-foot west-northwesterly (285-degree, deep-water) swell (with an 8- to 12-second period) will remain at this height and period through Tuesday. An 8- to 10-foot westerly (270-degree, deep-water) swell (with an 8- to 14-second period) will arrive along our coastline Wednesday, decreasing to 6 to 8 feet by Thursday. Combined with this westerly swell Wednesday will be 2- to 3-foot southerly (180-degree, shallow-water) seas. A 5- to 7-foot northwesterly (300-degree, deep-water) sea and swell (with a 5- to 12-second period) is forecast along our coastline Friday, decreasing Saturday.
Seawater temperatures will range from 60 to 64 degrees through Wednesday, decreasing Thursday through Saturday.
PG&E safety tip: When driving in the rain, slow down! It takes longer to stop or adjust in wet weather. Stay in the middle lanes — water tends to pool in the outside lanes — and don’t follow large trucks or buses too closely. The spray created by their large tires reduces your vision. Before it starts to rain, replace old or brittle wipers.
