A cool, slow moving 1,004 millibar low pressure system will approach Northern California on Monday, with the associated cold front reaching the Central Coast on Tuesday with rain, according to John Lindsey, a communications specialist with Pacific Gas and Electric Co. and longtime local forecaster.
Expect rain to total between a 10th to a quarter of an inch of rain, said Lindsey, The Tribune's Sunday Weather Watch columnist.
A strong 1,036 millibar eastern Pacific high combined with Tuesday’s low pressure system will produce a very steep pressure gradient along the California coastline, Lindsey said.
That's expected to produce northwesterlywinds between 32 and 46 mph, with gusts reaching 55 mph along the coastline late Tuesday into Thursday, he added.
Never miss a local story.
Also expect cooler temperatures, Lindsey said, well below normal for this time of April.
Highs will reach only the 50s along the coast to the mid 60s in the North County.
Warmer and dry weather is forecast on Friday through the weekend.
