A dense fog advisory has once again been issued for the Central Coast Wednesday morning. The advisory covers the coastal and coastal valley regions from San Luis Obispo County through northern Santa Barbara County and will remain in place through 9 a.m. Highways impacted include Highways 1, 101, and State Routes 154 and 246. Morning commuters should use low beams and increase their following distance as visibility on the roads could be decreased to one-quarter mile or less.

Daytime highs continue to trend down Wednesday as a low-pressure system stemming from the Gulf of Alaska shifts in over the area. This means most inland valley locations will be back in the mid to upper 80s range and coastal valleys will stay between the mid-to-upper 70s. At the coast, temperatures will stay right around average and between the mid to upper 60s.

Northwesterly winds will increase Wednesday, ranging from 15-17 miles per hour. These conditions should actually make for a fairly clear day.

The chances of rain remain in the forecast. As a cold front sweeps over the Central Coast Friday, temperatures will decrease and there will be a 20% chance of rain Friday night through Saturday morning. Right now, it seems most of the precipitation could be concentrated over San Luis Obispo County and the mountains and foothills in Santa Barbara County. As for rainfall totals, this system is expected to bring light right that could potentially cap out at only a few hundredths of an inch.
