The unofficial start to summer will certainly feel like that for some over the next few days. A ridge in the upper atmosphere is building in and that will at first crank up some wind, as we've seen today, and ultimately shrink the marine influence allowing temps everywhere to climb.

At first this warm-up will be subtle on Saturday with 70s at beaches and 80s in the coastal and interior valleys, but Sunday coastal valleys jump into the 80s while interior valleys head into the 90s. Beaches will warm but not as dramatically. Monday inland valleys will be near 100 and stay there thru at least Wednesday. Coastal valleys will be in the upper 80s and lower 90s Monday to Wednesday and beaches stay in the 70s.

A wind advisory continues into early Saturday for Santa Barbara County's Southcoast and mountains, passes and canyonss for winds which could gust to 30-45mph.

There is one piece of the forecast that could change. The current coastal forecast assumes some marine influence, if high pressure knocks it out the forecast could require a boost for temps into the 80s. Models show some onshore flow at times, but if this breaks down the entire area could be warm next week. Don't be surprised to see heat advisories, other parts of California already have them Monday-Thursday.

Relief likely comes Friday from an upper low, but these are notoriously hard for models to pin down. Right now I think it gets here Friday to deepen the marine influence and cut temps for some up to 15 degrees. Stay tuned for fine tuning on those parts of the forecast.
