Building high pressure will cause inland valley temps to leap to near or above 100 degrees Tuesday. Other inland valleys, like the Santa Ynez valley will be in the upper 80s to lower 90s. At the coast the story is a little different, it’ll be warmer but NW afternoon winds will help keep temps somewhat in check. I expect mid 80s for the SLO area with Santa Maria near 80. Upper 70s and lower 80s for the Southcoast. Beaches will be in the upper 60s with exceptions of SW facing beaches like Avila which should run in the mid to upper 70s, and low 80s can’t be ruled out.
An upper level trough will dig into the Pac NW Tuesday through Thursday which will produce coastal clouds and generally cooler temperatures, even inland temps back off later this week after running above normal through Thursday.
Weekend conditions also interesting as models are advertising an upper level low to push up from the south. This should keep clouds in the forecast and highs in the 70s near the coast with 80s inland.
Hurricane Bud south of Baja Mexico will push toward Cabo San Lucas producing some 5-7ft south swell in southern CA and parts of the Southcoast. The system should be watched carefully as leftovers will ultimately make it into the American Desert SW.
Bud still has the opportunity to gain some additional strength during the next 12 hours or so before the environmental conditions become less conducive and the cyclone gradually encounters the cooler waters near the Baja California peninsula in about 3 days. By then, Bud is expected to be below hurricane strength.
