Cloudy and dry before more rain Wednesday

Posted at 4:25 AM, Jan 08, 2019

A mix of mid and high clouds will hover over the Central Coast today as a low-pressure system spins off in the Pacific north of us.

Weak ridging will keep conditions dry and warm up temperatures. Daytime highs Tuesday will range from upper-50s in the interior valleys to mid-60s for coastal and beach locations.

Winds will begin to pick up this evening out of the south, 20-30 mph.

The cold front will hit Northern SLO County first, at about midnight tonight. Showers will turn into heavier rainfall Wednesday morning and south winds will increase 25-40 mph.

The swell will also be big with the arrival of the Wednesday storm. A high surf warning will go into effect Wednesday morning for breakers 17-22 feet across the Central Coast.

Projected rainfall amounts vary widely. Some places may only see 0.10″ or less, while other areas could receive as much as 1+”. Generally, most rain gauges will collect between 0.25-0.75″ by Wednesday night.

Weak ridging returns Thursday to produce another dry, cloudy rain. Yet another low-pressure system is setting up in the Pacific to bring rain Friday.

The on-and-off pattern of wet and dry days continues through the weekend. Saturday looks to be dry while more rain is expected Sunday.

Additional systems are setting up to bring more wet, unsettled weather through next week. By next Thursday, some places on the Central Coast will have received more than 3″ of rain.
