After a couple of days of hot daytime highs, it's finally starting to cool down for the inland valleys. Instead of being in the upper 90s, temperatures for the inland valleys will range from the low to mid-80s due to cooler southerly flow. Saturday and Sunday, temperatures are going to warm back up as high pressure redevelops, which means daytime highs will be back in the 90s.
The coastal valleys will also experience some cooling Friday but it won't be as drastic and daytime highs will generally be from the mid to upper 70s. The marine layer and fog will fill in over the coast Friday morning, keeping temperatures cool throughout the morning before gradual clearing starts around 11 a.m. Daytime highs will be back in the low to mid-60s and some beaches, like Pismo Beach, could stay foggy through early afternoon.
Breezy conditions will continue Friday, ranging from 10-20 miles per hour and peaking Friday night around 6 o'clock for northern Santa Barbara County and the south coast region.
