SACRAMENTO, Calif. — A Heat Advisory is in effect Tuesday through Friday through the Central Valley from Redding to the Grapevine, including the surrounding foothills. Temperatures are expected to reach 100-109°F. Sacramento could reach 106, while Redding could get as high as 109.
Triple digit heat could last through Friday. The worst days of the week will be midweek.
Overnight lows will offer little relief with valley temperatures only dropping to the 60s-70s and foothill lows only dropping to the 70s to low 80s.
Winds will slow considerably as a high pressure system strengthens.
Poor air quality will also be a concern with the first SPARE THE AIR DAY of the year called for Tuesday. Very warm high temperatures along with a strong inversion and light winds will result in elevated ground-level ozone that is Unhealthy for Sensitive Groups.
