We had a nice early Fall storm today out along the coastline. Peak wind gusts in the populated areas were generally around 50 mph, but the usual exposed spots made it up into the 60-70 mph range. The highest I saw was at the Barview Jetty…73 mph.
Here in the valleys most locations were in the 25-30 mph range. This was a “southeasterly” storm where the deep center of low pressure was a long ways off and the gradient wasn’t straight southerly up the valley. In that case our wind generally doesn’t get too wild in the valleys.
Pretty quiet weather the next few days. We get our first “Fall East Wind” Wednesday. By that I mean high pressure develops to the north and then quickly flops down east of the mountains. WRF-GFS shows 40kts. easterly wind at about 2,000′ over Portland later Wednesday and Wednesday night. The first day of wind (Wednesday) won’t be too warm, but a nice day. 850mb temps zoom up into the upper teens range by Thursday afternoon though! Our forecast of 78 might be too cool.
The biggest story when I look ahead at the weather maps is that no one pattern or weather lasts for very long. It’s looking much more changeable. From trough to ridge to trough. Some model runs have a deep low close to the West Coast early next week. Others don’t; but something to watch.
