Bay Area Warmup Begins Ahead Of Excessive Heat Warning
SAN FRANCISCO (CBS SF) -- The National Weather Service forecast for the San Francisco Bay Area on Thursday calls for clear skies and much warmer temperatures in most areas as a five-day heat wave begins for much of inland California.
The National Weather Service has issued an excessive heat warning in effect from noon Friday through 11 p.m. Sunday for the interior valleys, foothills and mountains primarily in the far northern and eastern edges of the greater Bay Area and beyond.
High temperatures will range from 100 to 115 degrees, with overnight lows mainly in the upper 60s to mid-80s.
Dangerously hot conditions are likely across the interior beginning Friday and continuing into the weekend as daytime temperatures warm to between 102°-110°F. Thus, an Excessive Heat Warning has been issued. Onshore flow should limit heating near the coast/bays. #CAwx #CAHeat pic.twitter.com/AUoe0Qwdqb
