New Year’s Atmospheric River through 1/9 with a twist

Tomer’s Take: The atmospheric river (AR) continues through 1/9, but the storm systems weaken 1/3-1/9 once they move into UT, CO, NM. Snow levels remain elevated in the Sierra because of this warm, moist AR. They’re also elevated on 12/31 in the Wasatch with rain reported at the base of Park City. Snow levels should gradually fall on Sunday 1/1 at Park City as slightly colder air filters in.

My forecast video 12/31:

Steamboat received 8 inches in the last 24 hours. That puts them at 188″ for the season. It’s their snowiest December in a decade. And more snow is on the way through 1/9.

    Chris I absolutely love love love your forecasts and look forward everyday to your Blog and YouTube videos especially the colored maps. What I some what don’t understand is what the different colors indicate. Is it possibly that at some point you could explain what the colors show in the way of moisture and intensity or provide a link explaining it in detail?

    White is clouds.
    Green is light rain.
    Yellow is rain.
    Orange is heavy rain.
    Red is storming.
    Pink is mix precip.
    Light blue is light snow.
    Darker blue heavier snow.

    Great that will be 5$. Send it to Tomer
