A 1000 feet deep coastal marine layer and cool conditions will continue through the evening and night. Inland temperatures are much warmer this afternoon while dry conditions continue. Warm and dry conditions inland continue this week with cooler marine air along the immediate coastline. A cold front arrives late this week bringing a chance of rain and gusty winds. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... Conditions will be the warmest and driest today, followed by a cooling trend for Wednesday through Friday due to a weak upper low pressure system. That system will also bring a chance of light showers to the north facing mountains slopes, and a chance of marine layer drizzle to the coasts and valleys. Today minimum humidities will be in the 25 to 40 percent range for most areas, and 10 to 20 percent across the Antelope Valley (lowest east of the Highway 14 Corridor). Wednesday into the weekend, humidities will trend upwards with most areas remaining above 30 percent (except for 15 to 25 percent in the Antelope Valley). Onshore flow will dominate through the weekend, with gusts of 20 to 40 mph across the Antelope Valley and foothills in the afternoons and evenings, strongest Wednesay and Saturday. Gusts 20 to 40 mph will also be possible across interior mountains and valleys Wednesay and Thursday afternoon. This weekend an unseasonably cold low pressure storm system may pass over the region. This brings the potential for widespread showers, mountain snow (down to as low as 4000 feet), and a 10 percent chance of thunderstorms. Low confidence in details for the precipitation, but high confidence in gusty (possibly Advisory Level and/or Warning level) winds across much of the region. $$ ECC028-011300- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 1154 AM PDT Wed Apr 30 2025 Conditions will be the warmest and driest today, followed by a cooling trend for Wednesday through Friday due to a weak upper low pressure system.
