A very different pattern: Dry, sun, and fog

We are now about to experience very different weather from the wet, blustery conditions of most of November. The last precipitation for quite a while just passed through tonight..the remnants of a weakening frontal system. High amplitude ridging, associated with building high pressure over the eastern Pacific, will leave us high and dry for the remainder of the work week. The only risk...you guessed it...FOG, particularly tomorrow and Wednesday morning in the lowlands. But we should see plenty of sun later this week, and the mountains will be in sun nearly every day.

Our long range computer models..which have notorious problems with cold wave situations....are not agreeing over the weekend and beyond. Right now the US model..the GFS..shows a major arctic front passage with strong NE winds into Bellingham early Saturday and cold air streaming into our region. (see graphic) But no snow. The European Center Model..normally superior...has a different, warmer, solution. Anyway, I never get excited by snow and cold more than 5 days out...so lets wait until the models are all on the same page. But it is clear we will be dry for days with little or no wind. Normal temperatures. Exceptional weather for raking leaves.

Jim Forman of KING 5 should start preheating his wool hat and gloves, and Seattle DOT...well, you know.

Remember last year. We transitioned to cold and snow about a week later.
