    Today’s Forecast: Much cooler weekend

    Saturday will be chilly and clear to start with mainly clear skies. Through the day expect lots of sunshine with highs in the low to mid 50s. Sunday will be partly cloudy turning mostly cloudy as a storm approaches. Winds will turn breezy with scattered rain moving from north to south. Rain will clear by late morning Monday. Another storm will move in Tuesday afternoon. We will also be tracking several rounds of snow in the Sierra. Download the NBC Bay Area app for the latest forecast and video.

    FRIDAY

    Scattered showers will be possible Friday along with a noticeable plunge in daytime temps into the low to mid 50s for highs. Though coupled with a cool northerly breeze, it may actually feel cooler than that at times outside.

    The cooler air aloft will also help destabilize the atmosphere for convective showers, and given the lowering freezing levels to near or below 4,000 feet, some brief hail or thunder isn’t totally out of the question with stronger showers.

    A high surf warning continues for the coast as does a winter storm warning for the Sierra as snow levels dip closer to 3,000-4,000 feet and locally lower late on Friday. Look for both warnings to expire by Friday night as wave heights and showers decrease across Northern California.

    The next storm arrives Sunday with likely some higher rain totals compared to the two storms seen so far this week.

    Strong high pressure will lock in smoke and haze around the Bay Area into the holiday weekend, with 3 Spare the Air days declared from Friday through Sunday.  This means we’ve already seen 16 STA airs through Dec 31st vs. only 7 total from Nov-February associated with last year’s Winter air pollution season.  Dry weather patterns in Winter usually coincide with strong high pressure and temperature inversions (warmer air aloft, cool air below) that act like a lid over our region keep the smoky skies in place.  We’re still hopeful a change to some rain will happen around the middle of next week, so better air and hopefully some much needed rain will be making a comeback early in 2018.
