    Grab the mittens and the scarf.

    Waking up before the sun on Monday yielded freezing temperatures in parts of the Bay Area, with lows starting in the 20s and 30s.

    Freezing Start to Sunday

    [BAY] Freezing Start to Sunday
    With clearing skies and dewpoint temperatures in the mid 20s to lower 30s, all the signs are there for a very chilly night in the Bay Area. We'll likely see mid 20s in the colder spots Sunday morning (North Bay valleys, East Bay/Tri-Valley into Solano County and areas near San Jose southward. Freeze warnings will expire around 8am as the Sun slowly thaws us out through the day. Highs will be quite cool as well with mainly 40s to low 50s to wrap up the weekend. Be prepared for another frosty, freezing night heading into Monday morning before temps slowly climb a few degrees approaching midweek. Dry weather is expected to continue into next weekend when we may be hosting the NFC Championship game at Candlestick at noon next Sunday the 20th (provided the Seahawks beat the Falcons). Hope you enjoy your Sunday - Rob Mayeda (Published Saturday, Jan 12, 2013)

    That's following on the heels of weekend weather, where at times, it was colder than Alaska.

    Bay Area temps dropped to new lows on Sunday that at least briefly were actually colder than parts of Alaska.  At 6 a.m., temperatures in Anchorage saw 35 degrees, and it was 34 degrees in Juneau. In the Bay Area, it was 24 degrees in Santa Rosa, 27 in Livermore and 29 in San Jose.

    Colder than Alaska?

    [BAY] Colder than Alaska?
    Bay Area temps dropped to new lows this morning that at least briefly were actually colder than parts of Alaska. At 6am temps in Anchorage included 35 degrees with 34 in Juneau, meanwhile in the Bay Area we had 24 in Santa Rosa, 27 in Livermore and 29 in San Jose! How is this possible? While high pressure provides a more mild, southerly wind flow to the Gulf of Alaska, on the east side of this high, very cold continental polar air continues spilling down north to south into California. Highs will be in the 40s to low 50s then quickly retreat after sunset tonight. More temps in the 20s and 30s are likely into Monday morning in areas that are wind-free. Some of the higher hills may see some briefly gusty winds as an offshore wind pattern begins to develop, this will also keep some areas with slightly warmer temperatures overnight. Temps should slowly climb beyond midweek as high pressure centers itself more directly over the West Coast. Try to keep warm and enjoy your Sunday! - Rob Mayeda (Published Sunday, Jan 13, 2013)

     While high pressure provides a more mild, southerly wind flow to the Gulf of Alaska, on the east side of this high, very cold continental polar air continues spilling down north to south into California.

    The cold snap is being felt throughout California. The temperature in downtown Los Angeles dipped to a record low: 35 degrees at about 4 a.m. The temperature was the lowest recorded temperature since Dec. 24, 1990, when the low reached 35 in downtown. On Dec. 22 and 23 of 1990, the low reached 33 and 34 degrees, respectively, according to the National Weather Service.

    Temperatures have not dropped to freezing in downtown LA since Jan. 29, 1979.

    The National Weather Service issued another local freeze watch for San Diego, too.

    Temperatures in the Bay Area should slowly climb beyond midweek. Each day should see about a 5 degree increase, until Saturday when it should peak at either the high 60s or isolated 70s.
