The heatwave continues Wednesday as triple-digit temperatures dominate the forecast.
A change to the forecast includes an Air Quality Alert, which will remain in place through the 10 o'clock hour Wednesday morning. The alert was issued due to smoke from nearby wildfires, like the River Fire which is burning in Monterey County. Those with pre-existing health conditions that are sensitive to poor air quality should be cautious about how much time they spend outdoors Wednesday.
The excessive heat warning over the inland valleys and the heat advisory over the coastal regions are both set to remain in place through Thursday at 9 p.m. Daytime highs for the beaches will range from the low 80s to the low 90s with peak wind speeds up to 25 miles per hour. Across the coastal valleys, daytime highs will continue to peak in the 90s and low 100s with northerly winds starting out mild in the afternoon before potentially peaking at 25 mph Wednesday night. The inland valleys will continue to have daytime highs well above average. Most inland valley temperatures will range from the low 100s to about 114 degrees Wednesday with peak wind gusts up to 25 mph.
The high pressure that is bringing the heat will begin to weaken Thursday, which means daytime highs will begin to trend down. Although these temperatures will be cooler than what's in the forecast Wednesday, it will still be a warm end to the week. The weekend will include daytime highs in the 90s and low 100s across the inland valleys, the coastal valleys will be close to the upper 70s and upper 80s, and the beaches will be right around the low to upper 70s.
