Freezing Forecast



    Look Forward To A Mild & Sunny Monday In The Bay

    Monday looks mild and dry with a mixture of sun and clouds. After a very cold start, high temperatures are expected to climb into the low 60's, right on track with seasonal averages for this time of year. (Published Monday, Feb. 28, 2011)

    The hope of snow is long gone in the Bay Area, but the frigid temperatures will remain through the rest of the weekend, according to forecasters.

    Once again Bay Area overnight temperatures ranged in the 20s and low 30s. That was low enough to warrant a freeze warning in our North, East Bay and Salinas valleys. A freeze warning means sub-freezing temperatures are impending or highly likely.

    Residents are urged to check on elderly neighbors and to ensure that heating systems are working properly. (And don't forget your pets).

    NBC Bay Area's Rob Mayeda says we'll see mostly sunny skies Sunday making for a pretty sunset later this evening.

    Mayeda says the clouds are giving hint at an increasing chance for some showers for areas north of San Francisco starting Monday morning. Early in the week the rain should stay to the North Bay before things turn windy and wet for everyone by Wednesday.

    That midweek system could pack rain rates high enough for some spotty runoff/flooding issues in the usual locations with 1"-2" rain.

    The forecast for next weekend also includes rain thanks to a fairly active pattern that continues to be target the West Coast.

    Cold Snap Continues

    [BAY] Cold Snap Continues
    Snowfall reports were fairly sparse around the Bay Area on Saturday, but when it did come down near Hollister, Gilroy and the Carmel area - it did look pretty impressive. The clip at the beginning of this weather forecast shows wet snowflakes reaching sea level courtesy of a heavier shower. What you are also seeing are ice pellets, sometimes called 'graupel' that are small, soft bits of ice that fall to the ground, sometimes confused with hail. One of the differences you may find is these 'graupel' or ice pellet showers occur without any thunder or stronger convective updrafts. In any case, the moisture has moved on and as skies clear and some pretty chilly air remains behind - we'll wake to 20s and 30s and patchy ice around the Bay Area on Sunday morning. With more sunshine, afternoon highs should reach the low to mid 50s. Then as we move into the work week - look for rain starting north of San Francisco on Monday, and for the most part hanging out north the Golden Gate through Tuesday. Then Tuesday and Wednesday, computer models spin up a 992-998 mb low and track it towards southern Oregon. Should this pan out, we should see some fairly gusty conditions for Wednesday and what should be our rainiest day of the week as well. Some showers will follow into Thursday before things dry out a bit for Friday. The work week pattern will be more 'zonal' in nature - meaning our incoming weather systems will be more mild while at the some time, packing more moisture as well. Enjoy your Sunday! - Rob Mayeda
