The start to the three-day weekend will be slightly cooler and windy.
A wind advisory has been issued for most parts of San Luis Obispo and Santa Barbara Counties Friday. For SLO County, the advisory will be in place from noon until 7:00 p.m. with potential for northwesterly wind gusts to reach 35 miles per hour. For Santa Barbara County, the advisory will last from 3:00 p.m. to 3:00 a.m. with wind gusts up to 50 mph.
There will be about five to ten degrees of cooling Friday as a upper level low moves over Northern California. Temperatures along the coast will be closer to the mid-60s and low 70s and parts of the coastal valley communities will be right around the upper 60s to the mid-70s. Inland valley communities will also experience slightly cooler conditions as temperatures drop to the mid-70s and low 80s.
High pressure will build over the state by Sunday, which means hot temperatures for the inland valleys. Most interior portions of both counties will range from the low to upper 90s through the middle of next week.
