Central Coast Weather Report: Long Range Models Show Seasonal Dry Temperatures | Local news

It may sound contradictory, but the last sunrise of the year was Friday morning, about two weeks after the first day of winter. Conversely, the first sunset occurs about two weeks before the winter solstice. This can be visualized by the “equation of time” graph on a sundial.

A weak cold front is expected to produce increasing clouds with pockets of drizzle on Saturday morning as it dissipates over the central coast. Snow levels are expected to remain above 5,000 feet.

Behind the front moderate to cool winds (13-24 mph) from the north to the east and clear skies will develop on Saturday afternoon and overnight. However, tule fog is expected to persist for most of the day in the San Joaquin Valley.

Another weak low pressure system off the central coast will produce areas of fog and haze and light to moderate winds (8-18 mph) south to northwest (onshore) from Sunday to Monday. If the system moves east enough, it could produce rain showers from Sunday evening to Monday morning.

Moderate to cool winds (13-24 mph) from Santa Lucia (northeast) forecast Tuesday through Wednesday will produce mostly clear skies and mild temperatures in coastal areas.

Gentle to moderate winds (8-18 mph) from the northwest (onshore) will allow the marine layer to develop along the coast from Thursday to Friday.

Long-term models continue to indicate that dry, seasonal temperatures will continue through mid-January or even longer.

Sea water temperatures will vary between 55 and 57 degrees until Monday.

Saturday’s 4 to 6 foot northwest (285 degrees, deep water) swell (with a period of 8 to 17 seconds) will remain at this level until Sunday. This swell will decrease to 3 to 5 feet (with a period of 11 to 13 seconds) on Monday.

A 968 millibar storm with hurricane force winds near the international date line will generate a swell 8 to 10 feet west-northwest (280 degrees, deep water) (with a period of 16 to 18 seconds) which is expected along our coast from Tuesday to Wednesday.
