Low pressure brings cooler weather, deep marine layer, chance of thunderstorms in parts of region

There is a chance of showers and thunderstorms in the forecast from today until Wednesday. It will impact the Ventura County Mountains, much of San Luis Obispo, and Santa Barbara Counties. There is a 20 to 30 percent chance of showers and thunderstorms on Monday afternoon. Later on that evening, it's a 20 to 40 percent chance.

It will also bring some slick roads, so it is important to drive carefully. The visibility could drop significantly in parts of the region. At around 7:30 this morning, the visibility will be a tenth of a mile in Lompoc and Gaviota; driving within distance is crucial. 

A Marine Weather Statement is in effect Monday afternoon. A low-pressure system will bring a slight chance of thunderstorms to the coastal waters north of Point Conception this afternoon through Tuesday morning. Cloud-to-water lightning, gusty winds, and small hail are possible with thunderstorms and a slight chance of waterspouts.

Onshore flow is airflow coming from the Pacific Ocean. The deep marine layer and strong onshore flow have combined to bring low clouds to our region's coasts, valleys, and even mountain passes.
It will also bring cooler temperatures to our region, so bundle up and have your umbrella ready until Wednesday.
