A cold, overcast, and drizzly start to your Thursday will be followed by partial clearing this afternoon.

As the onshore flow continues, a passing trough will bring lower temperatures, dropping us far below typical levels for this time of year.

Normally, we'd be in the high 60s near the coast and the mid-70s inland, but most regions west of the mountains will battle to get out of the 60s today.

The National Weather Service predicted strong westerly winds over San Diego County's mountains and deserts from Sunday to Tuesday.

Wind gusts of 50 mph or higher are forecast in various county deserts until Sunday evening, according to a wind advisory.

Cooler days and a coastal eddy with strong south winds and clouds near the coast were forecasts.

According to the meteorological service, high temperatures near the coast will reach 69 degrees, 71 to 76 degrees in the western lowlands, 66 to 75 degrees in the highlands, and 92 to 97 degrees in the deserts on Sunday, as per the Times of San Diego.

Forecasters expect the marine layer to thicken a little further through Monday and to leak some scattered precipitation at times, but most portions of the coastal basin should stay dry and experience some sun each day.

A weak ridge was predicted to travel east with diminishing winds from Wednesday through Friday, bringing milder days.

The ridge was expected to give way to larger troughing across the West Coast over the weekend, laying the stage for milder weather through early next week.

Winds from the west to the northwest were anticipated to gust to 20 knots in the outer coastal seas on Sunday. Aside from that, no dangerous maritime weather was forecast until Thursday.

Classic springtime weather

The typical springtime weather system of gale-force northwesterly winds and freezing seawater temperatures will persist for the majority of next week.

A pattern of strong to gale-force (25 to 38 mph) northwesterly winds developing in the afternoon, reducing and changing out of the north to the northeast (Santa Lucia/offshore) during the late-night and morning, will proceed through Tuesday, producing mostly clear skies, with the exception of areas of overnight fog along the beaches and coastal valleys on Monday and Tuesday.

This week, high pressure will build over the Central Coast, resulting in considerably higher temperatures away from the ocean, as per The Tribune.

Today's extreme temps will range from the low to mid-80s in the inland valleys (Paso Robles) to the low to mid-70s in the coastal valleys (San Luis Obispo).

The beaches will be in the upper 50s to low 60s, with the exception of the southerly facing beaches (Cayucos, Avila Beach, and Shell Beach), which will be in the mid-70s.

A Catalina eddy circular counterclockwise airflow can be difficult to anticipate since it normally spans a tiny region of the Southern California Bight, which is expected to occur later Tuesday along the coast from Point Conception to just south of San Diego.

A trend of moderate gale-force to fresh gale-force (32 to 46 mph) northwesterly winds developing in the afternoon and diminishing throughout the night and morning will begin Thursday afternoon and last through the weekend.

Such winds ought to be powerful enough just to mix out the temperatures inversion/marine layer, allowing for a generally clear sky.
