Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
A 1,011 millibar low-pressure system will develop over the Central Coast on Sunday into Independence Day. This low-pressure system will produce gentle to moderate (8 to 18 mph) southerly winds, partly to mostly overcast skies with pockets of fog and mist along the coastline and slightly below-seasonal temperatures throughout San Luis Obispo and northern Santa Barbara counties.
Some of the coastal firework displays could be partially obscured by the marine layer. However, some of the models are indicating a relatively high cloud ceiling (near 1,000 feet) developing on the evening of the Fourth of July, which will allow for nice viewing.
The northwesterly winds will increase Thursday into the weekend, producing clear skies during the afternoon and evening hours in the coastal regions and warmer inland temperatures. High pressure is forecast to further strengthen this weekend for even warmer temperatures. In fact, Paso Robles may see triple-digit highs.
A 4- to 6-foot northwesterly (305-degree, deep-water) swell (with an 8- to 11-second period) is forecast along our coastline on Saturday into Sunday, lowering to 3 to 5 feet on Monday. A 6- to 8-foot northwesterly (310-degree, deep-water) swell (with an 8- to 11-second period) is forecast along our coastline on Tuesday, decreasing to 4 to 6 feet on Wednesday. Increasing northwesterly winds will generate a 4- to 6-foot northwesterly sea and swell (with a 5- to 8-second period) on Thursday into Saturday.
Arriving from the Southern Hemisphere: A 1- to 3-foot Southern Hemisphere (210-degree, deep-water) swell (with a 15- to 17-second period) will arrive along our coastline on Sunday into Monday.
Seawater temperatures will range between 55 and 58 degrees into Friday.
