Here is this week’s weather forecast by PG&E meteorologist John Lindsey.
Last week’s Santa Lucia (offshore) winds produced warm and clear conditions. This week will be a different story.
An approaching Pacific low-pressure system will produce gentle southerly (onshore) winds and plenty of marine low clouds with pockets of mist and drizzle along the beaches and in the coastal valleys along with variable mid- to high-level clouds for the rest of the county today into Thursday.
The associated cold front is forecast to drop southward through the Bay Area by late Wednesday, then slide down to Big Sur early Thursday morning.
This cold front may be just strong enough produce a few light rain showers in San Luis Obispo County by late Thursday morning. Given the mild nature of the system, snow levels are expected to remain above 6,000 feet with 3 to 5 inches of new snow possible across the northern and central Sierra.
This cold front will be followed by strong to gale-force (25- to 38-mph) northwesterly winds along the coastline and clearing skies. Another round of Santa Lucia winds will develop during the night and morning hours Friday into Saturday.
The long-range models are suggesting a wet-weather pattern for San Luis Obispo County for the middle and latter part of next week (Nov. 18 through 21).
Late Friday night, a storm from the remnants of Typhoon Nuri intensified to 924 millibars in the Bering Sea. This was the lowest pressure ever recorded in the North Pacific Ocean region. The previous record was 925 millibars recorded at Dutch Harbor in October 1977. Since this storm was on the northwest side of the Aleutian Islands, a majority of its swell energy was blocked from entering into the Eastern Pacific Ocean.
However, a 4- to 6-foot northwesterly (300-degree, deep-water) swell (with a 20- to 22 plus-second period) from this historic storm will arrive along our coastline later today and remain at this height but with a gradually shorter period through Thursday.
A 7- to 9-foot northwesterly (300-degree, deep-water) sea and swell (with a 5- to 15-second period) will develop along our coastline Friday, decreasing to 4 to 6 feet (with a
7- to 13-second period) Saturday into Sunday.
Seawater temperatures will range from 60 to 64 degrees through Thursday morning, decreasing Thursday afternoon through Saturday.
