We had a marvelous summer. Then during the second half of September we were tested by some unseasonably wet and windy weather. And last week has been nothing to brag about.
But everything is about to change. The next week is going to be glorious, with no precipitation, warming temperatures, and plenty of sun. Some clouds midweek and maybe some morning fog on a few days...but nothing serious.
Who or what should you thank for this boon? A high amplitude, persistent ridge of high pressure in the eastern Pacific that will be locked down for many days. What meteorologists call a blocking pattern.
Let me show you some graphics: a series of upper-level maps (500 hPa heights--the height of the 500 hPa pressure above sea level). As you know, high heights are associated with descending air and dry/warm conditions. The best conditions in the midlatitudes are just downstream (in this case east) of the center of the ridge.
This morning we find a weak trough over the Northwest...and yes plenty of clouds and some showers are being observed. There are rapidly weakening now and I am hopeful for dry conditions by the time of the big game. Ducks don't like dry weather.
Folks this is a very favorable pattern for us...if you like sun and warmth that is. You notice there are strong troughs (areas of low heights or pressures) on both sides of the ridge? We are seeing the development of an omega block...looks like the Greek letter omega... which is often a very stable and persistent pattern.
Monday...the ridge is still there!
And to show you that the National Weather Service is on board with this forecast, here is the 6-10 day forecast from the Climate Prediction Center. Warmer than normal over us. WAY warmer than normal over Alaska. Good time for a cruise.
Finally, let me remind those in Bellingham that I will be talking about the future of weather forecasting at Bellingham High School on Tuesday night at 7 PM. More information here.
