The significant heatwave will cause temperatures to rise on Friday

Update: On Friday night, winds will shift to the north leading to sundowner winds along western portions of the Santa Ynez range and Santa Barbara south coast.

A Wind Advisory was issued for the southwestern portion of Santa Barbara County until 5 a.m. on Friday, where wind gusts are expected to reach between 45 to 50 mph. These north winds will push the hot, dry airmass to the coasts.

Sundowner winds tonight will lead to hot, dry conditions for Santa Barbara County's south coast, with highs pushing into the 90s Friday, and most coast and coastal valley areas are expected to jump 10 to 20 degrees warmer.

°, coasts will also start to heat up with highs climbing into the upper 90s even in coastal valleys. This will make for the hottest day of the week for most communities likely reaching record highs.
