Or the change in wind direction? My wind chimes are ringing and the cool breezes are extraordinarily pleasant. Both the Huskies and Seahawks won this weekend, and all is right with the world.
There was a distinct contrast today in sky conditions--with a band of clouds along the Washington and Oregon coasts that extended southwestward over Oregon. (see satellite pic above). Even some light rain showers on the coast. An upper trough aloft has been slowly approaching and this afternoon its influence initiated the push of marine air eastward. Take a look at the surface chart this afternoon--southwest winds pushing into Puget Sound...with some winds gusting to 15-20 kts. In the Strait of Juan de Fuca, westerlies are moving eastward. The result..tomorrow will be cooler and cloudier--particularly in the morning--with some sunbreaks in the afternoon. Well, at least it will make it easier to go to work.
The weather observations at the UW (shown below) indicate that the temperature is about ten degrees cooler than yesterday at the same time. You can see the switch to southwesterlies around 11 AM (18Z) and the steady rise in pressure as cool, dense air moves in. And the winds!
There have been a number of comments to the blog about El Nino..and I will talk it about it more this week... but keep in mind that El Nino has little impact on our summer or early fall weather--so you CAN'T blame this wonderful September weather on the tropical Pacific so easily! And a number of you want some guidance on purchasing that season pass at Snoqualmie Pass or some other ski area. More on that later! So hold off for a few days.
