For the forecast, an upper ridge will bring sunny conditions for today before shifting East Sunday evening allowing a cold front to move into our area for Monday into Tuesday, bringing unsettled conditions. Some cloud may be hanging around some of the peaks during the day.  A weak upper level trough will bring unsettled conditions to the area on Wednesday. Way long term, there is the possibility of a cold front moving in for next Thursday evening with some snow expected. Unfortunately the freezing levels will be hovering around the 1000 meter level to 1300 meter level for most of the week during daylight hours. We will see the FL drop to the valley for the next couple of days during the evening\early morning hours. 



    High pressure is holding off the Coastal precipitation for today.


    Some moisture for Monday night into Tuesday.

    There was some convective cloud development on Saturday.

    Must have been 150 Santa's on the hill.

    Santa on some wind affected snow.

    Many people heading up Pika's Traverse before the Peak chair was open.

    It was an awesome day, on a busy Saturday.

    Lots of cool light shows on Saturday.

    Stratus layer was very slow to dissipate, then convective clouds began to form.
