SLO County weather forecast for the week of Dec. 28

Here is this week’s weather forecast by PG&E meteorologist John Lindsey.

A cold front and upper-level trough will produce a few scattered rain showers throughout the Central Coast on Monday morning. These scattered showers will be followed by strong to gale-force (25 to 38 mph) northwesterly winds and cool temperatures Monday afternoon and Monday night. Total rainfall amounts will generally be below one-tenth of an inch. Snow levels could be as low as 3,500 feet.

High pressure will build over the Great Basin and produce persistent Santa Lucia (northeasterly) winds. These winds will produce clear skies with cold mornings and mild afternoons starting Tuesday and continuing through Friday, New Year’s Day. The dry weather will continue through Saturday as a normal winter dry spell.

Increasing southerly winds, clouds and warmer temperatures are expected Sunday, with potentially heavy rain developing next Monday and possibly continuing through the week as a series of storms move through the Central Coast.
