It’s raging out there in the Gorge this evening, but gusts (so far) in most spots have stayed slightlty below what we saw back in late November. Here are the peak gusts as of 9pm:
Troutdale Airport: 43 (44 in Nov)
SE Troutdale (near MHCC): 53 (59 in Nov)
Washougal: 50 (56 in Nov)
Corbett School: 71 (75 in Nov)
83 87 (89 in Nov)
Biddle Butte: 75 (higher than last winter or November)
Skamania: 65 (not working in Nov)
That Vista House gust to 83 is likely not the highest gust observed for two reasons. The sensor was offline from midnight to noon, we missed 12 hours of observations. Maybe more important, if you look at the observations, you’ll notice that it often misses reporting times; not sure why it does that. But the gust shown on the observations is the highest in the last 10 minutes. So if there are 30-45 minutes between reports, it’s only including the gust over the past 10 minutes. Obviously a higher gust may occur and not get reported. The Corbett observation that goes out on CWOP/MADIS does not include the highest gust either, that is here.
The wind may ramp up a bit further as we head towards sunrise; it often does as warmer air moves in aloft and the pressure gradient tightens just ahead of an approaching system coming in from the southwest. So tonight will likely see the strongest wind.
It’ll back off dramatically, but not go away totally, tomorrow afternoon/evening as the light precipitation moves through.
I’m not working tonight, but wanted to get those windspeeds on record here…
