    PM Weather - 80s in the LA Basin All Week

    It's looking like 80s all week longs, as we leave summer behind. David Biggar has your First Alert Forecast on NBC4 News at 5 p.m. on Sept. 22, 2018. (Published 32 minutes ago)

    Highs will be a bit cooler on Sunday as a weak area of low pressure passes by to our north. This will help to keep the marine layer around through Tuesday morning, and may even develop a few clouds over some of the mountains. The cooling will continue into Monday, before temperatures start to rebound heading towards midweek.

    The marine layer will thin out as temperatures warm up, and may be mostly gone by early Wednesday morning. The warmest day of the week ahead looks to be Friday with inland highs in the mid 90s.

    Sunday’s Forecast:

    Coast: Low to mid 70s, early low clouds, sunny afternoon.

    Basin: Low to mid 80s, early low clouds, sunny afternoon.

    Inland: Upper 80s to low 90s, sunny.

    Mountains: Low to mid 70s, a few clouds.

    High Desert: Low to mid 90s, mostly sunny.
