A bit of a change since the last monthly run; ridging more over us instead of farther to the west about a week from now and beyond.

    Hey it’s snowing in New York City!

    Lets keep one thing into perspective here.

    None of the centers of these ridges depicted on these maps is centered right over the PNW. The center is offshore. That may mean nothing or it could mean weather systems could find ways to slide down the backside to give us all at least a cool rain.

    As for snow? That is totally up in the air as usually because a mostly land trajectory tends to lead to lighter and less precipitation. I would tend to say that any overrunning events that would give a better chance of good accumulating snow in this time frame would have a really low chance of happening. Not a zero chance but pretty close to it.

      Thank you. It’s nice to see someone being reasonable.

      Greg, snow is usually up in the air. I’ve never heard of it snowing upwards! Haha just kidding bud.

      Not to mention the weekly maps and ensembles and maps etc. etc. etc. could always flip again just like they usually do when cold shows up and then goes away. It goes the same for warm. Really its a crapshoot past 7 days. Right Jesse?

    Those maps tell me this….
    ‘Tis the Season for Inversions, Ridges, Lack of Moisture, East Wind, and Columbia Basin cold pools.

  4. @pdxduck: Ridge generally means warmer and drier. Trough generally means wetter and cooler.

    Well there goes the ski season Mark.

    Stick a fork in it. The winter of 2013-14 is over!

    What’s the layperson’s translation of this? 🙂
