Something new for our east wind event…this link is for unofficial MEASURED windspeeds only. Place the Time, Location, and Peak Gust in a comment below. No discussion here please and I’ll take care of the mesonet/NWS peak speeds too…Mark
Not much change tonight except the next weather system offshore is clearly pumping up the upper-level ridging over us. In response, high pressure at the surface is developing quickly. The PDX-DLS gradient (easterly through Gorge) is past 6 millibars already this evening and the wind gusts are responding. Over 30 mph at TTD and 51 mph at 9:15pm up in Corbett. We are now in a similar setup to last week’s east wind event, although a bit warmer for now. I assume the gradient will pop up to 10 millibars or so by tomorrow evening. One difference this time will keep the wind going through Friday…a surface trough or low approaches from the southwest Friday, which is always good for very strong wind at the end of an east wind event. So this will probably be the strongest wind event of the season so far.
A pretty obvious change on the long range maps this evening. We transition to an active westerly jet and rainy weather Friday night and into next week. Earlier GFS today had quite a bit of rain over us Sunday-Monday, newer model does not have that.
Tie everything down if you live east of I-205! Mark
