A cooling trend is starting Thursday as an upper-level trough begins to move in over the state. This means that cooler daytime highs will be in the forecast for the coastal regions due to Seabreeze influence, but the inland valley communities will stay hot.
Daytime highs for the beaches will be closer to average with temperatures in the 70s, while the coastal valleys will range from the mid-70s to low 80s. The inland valleys will stay on the warmer side, with peak temperatures from the low 90s to low 100s.
Most of the coastal regions will have mild winds Thursday, with peak winds staying close to 15-20 miles per hour. Southwesterly winds will increase across the interior valleys, the same areas that will have hot temperatures, and reach 25-30 mph by Thursday evening. Some weather models are showing that winds could stay gusty through 9:00 p.m.
Cooler daytime highs are still on tap for the weekend. Starting Friday, there will be increasing winds and the morning marine layer will make its return, which will be a trend that sticks around through the rest of the weekend.
