Central Coast Weather Report: Rain Showers Expected Saturday | Local News

After a long period of dry weather at the heart of our rainy season – the entire central coast went from moderate to severe drought according to Thursday’s drought watch map – rain showers are expected on Saturday.

A cold front will move south across the central coast from Saturday morning to Saturday evening with mild to moderate southerly winds (8 to 18 mph), cooler temperatures, rising clouds and, most importantly, showers rain.

The European model (ECMWF) predicts between 0.10 and 0.33 inches of rain, while the American (GFS) predicts less than 0.10 inches on Saturday. Saturday’s highs will only reach the mid 50s to low 60s, with snow levels falling to 4,500 feet.

Postfrontal northwesterly winds and clear skies are expected Saturday evening through Monday.

On Tuesday, increasing high pressure and gusty winds from Santa Lucia (northwest) will produce mostly clear skies and warmer temperatures. Many Central Coast locations are forecast to hit the low to mid-80s on Tuesday and Wednesday, 10 and 15 degrees above average for the end of March. Note: These predicted highs are near or above the daily highs.

The marine layer is expected to re-develop in coastal regions as winds shift from the northwest (onshore) on Thursday and Friday. Dry conditions are expected to continue through the end of March, then wet weather may develop during the first week of April.

Sea water temperatures will fluctuate between 51 and 53 degrees until Friday.

Northwesterly 4 to 6 foot seas (300 degrees, deep water) and a swell (with a period of 7 to 14 seconds) will continue at this level through Saturday morning.

A 3 to 5 foot northwesterly swell (290 degrees, in deep water) (with a period of 8 to 12 seconds) is forecast along our coast Saturday afternoon.

Strong to gale force northwesterly post-frontal winds (25 to 38 mph gusting to 50 mph) will cause wave heights to increase rapidly Saturday evening. NW 8-10 foot seas (310 degrees, deep water) and swell (with a period of 5-12 seconds) are expected Saturday evening through Sunday.

This sea and northwest swell (310 degrees, deep water) will decrease to 6 to 8 feet (with a period of 7 to 11 seconds) on Monday, lowering further to 4 to 6 feet (with a period of 8 to 15 – second period) from Tuesday to Thursday.
