    While August tends to be the warmest month of the year in SoCal, this week we're running below normal, making for very comfortable weather. Shanna Mendiola has your First Alert Forecast for Sunday, August 20, 2017. (Published 6 hours ago)

    Climatologically, August is the warmest month of the year in Southern California and this week, but we've been running below normal, making for very comfortable weather.

    Morning marine layer today clears gradually to afternoon sunshine.

    As we head into the week ahead, temperatures won't fluctuate much, just cooling a degree or two as another push of onshore flow moves through the area.

    The only change will be a slight thunderstorm chance for our local mountains tomorrow as monsoonal moisture attempts to move into Southern California.

    We'll be monitoring conditions for Monday morning's highly anticipated total solar eclipse. Southern California won't be in the path of totality (62% of the sun will be covered in Southern California). We're crossing our fingers for a fast clearing marine layer to view the partial eclipse peak at 10:21am!

    SUNDAY'S FORECAST:

    MOUNTAINS - Partly Cloudy, High 70s

    HIGH DESERT - Sunny and Breezy, Low 90s

    INLAND EMPIRE- Early Marine layer clearing to sunshine, high 80s
