SYNOPSIS

11/1137 PM.

Moderate rain and a chance of thunderstorms will sweep through the area through this morning. Scattered shower activity is then possible this afternoon into Monday morning. Dry and warmer weather is expected the rest of next week.

LONG TERM (WED-SAT)

12/324 AM.

Not much excitement in the xtnd.

Look for a little ridge overhead on Wed. An inside slider will work its way down the state line on Thu. Followed by dry NW flow on Fri and Sat.

At the sfc there will be mostly onshore flow on Wednesday. Persistent offshore flow from the north will begin on Thursday while the E/W grad will diurnally shift back and forth from weak offshore in the morning and moderate onshore in the afternoon.

Cannot rule out some coastal low clouds but other than that and some ocnl upper level clouds skies will be mostly clear.

The passage of the inside slider will bring a two day north wind event with advisory level gusts likely through the I-5 corridor and the Santa Barbara county mountains.

Max temps will rise 2 to 4 degrees Wed and then change little on Thu. The offshore push on Fri and Sat will result in 2 to 4 degrees of warming each day and will push coastal highs into the 70s and vly highs into the 80s on Saturday (3 to 6 degrees over normal)

MARINE

12/325 AM.

A strong storm system will affect the southwestern CA coastal waters through this afternoon. This system will sweep a cold front across the waters through this morning, bringing Small Craft level southerly winds, showers and a chance of thunderstorms to the area. Potential hazards include: heavy downpours, dangerous cloud to ocean lightning, small hail, and erratic gusty winds. Boaters, especially those with small vessels, should avoid these conditions.

Seas will build to 8-10 feet today across the central and northern Outer Waters. Additionally, Small Craft level west to northwest winds are likely for all the waters Monday afternoon and night. Then northwest SCA winds are possible for much of the time across the outer waters Tuesday through Thursday night, with a 20% chance of Gale Force winds at times Thursday night.
