More Cold, But When Will It Snow?

The weather has been quiet the past 10 days or so as a large high pressure ridge has built in off the coast and has been anchored there. It has been far enough off the coast to allow cold air to come down from Canada into the Western U.S.

We will see more of the same this week as the ridge remains off the coast pushing the storm track up into Alaska and Canada. One fo the things we have been waiting to happen is for the Pacific North American teleconnection pattern to go negative. In the positive state it tends to cause the ridging near CA.

It is now entering back into a negative state. Looking at next weekend it appears that the ridge could shift back enough from the coast to allow then next cold trough from Canada to come further West towards the coast. That would allow it to pick up some moisture and bring the chance at some light snow around the 12th.

As we go past mid-month it looks like as the jetstream gets stronger it will push further South down the coast. Right now looking at the long-range forecast models it appears that week 2 will bring some bigger storms to the Pacfic NW. That will bring increased chances of light snowfall here.

Hopefully as we go further into the month the trend will continue and the big snows will return before the holidays. BA
