Temps Could Reach 100 in Tri-Valley

    Temperatures could hit in the 100s in parts of the inland Bay Area on Monday. Christina Loren reports. (Published Monday, Oct. 1, 2012)

    Temperatures may soar to 100 degrees Monday in parts of the inland Bay Area according to NBC Bay Area meteorologist Christina Loren.

    What comes with searing heat is an increase of fire danger and poor air quality, too. The hottest parts of the Bay will be the Tri-Valley area, Oakland should top out about 90 degrees, and the usually foggy San Francisco should reach 80 degrees.

    Summer-like Sunday Ahead

    [BAY] Summer-like Sunday Ahead
    SUNDAY: High pressure building through the day will warm inland temps through the 80s into the upper 90s near Livermore. This will be quite the temperature swing with many areas starting the day in the 40s and 50s, then about 40 to 45 degrees of warming through the afternoon! A weak sea breeze not only will lead to our warming temperatures but limit the mixing out of air pollution around the Bay Area = a Spare the Air alert for Sunday, with poor air quality likely for Monday as well with slightly warmer temperatures. AHEAD: Temps will begin cooling midweek and drop to slightly below average into the weekend with highs only in the upper 70s to low 80s inland by Saturday. There's a slight risk of some mountain showers around that time as well, so stay tuned! - Rob Mayeda VIDEO: Weather Team 7 Day
