The peak gust of 36 mph at PDX today was the highest (non-easterly) wind gust in about 5 weeks here. So of course a tree branch fell here or there.
Most of the heavier action was to the north in western Washington as mentioned in the previous post. Take a look at all the lightning strikes in Puget Sound!
Down here in our area the only cloud to ground strike was up in Cowlitz County. In fact we didn’t even see much rain, here are the rainfall totals since midnight:
Severe storms never developed in far NE Oregon and the watch has been cancelled.
So what’s ahead? Time to make up for all the dry and mild weather.
We’ve seen a very dry late winter and spring with upper level high pressure often sitting just offshore, keeping the storms that do make it inland quite weak. That changes for the next 7-14 days. The persistent upper level height anomaly offshore is gone, replaced by weak westerly flow through at least next Sunday-Monday. Then models are in pretty good agreement that our first chilly “Upper Level Low” we’ve seen in a month or two. Take a look at the next 4 weeks of the ECMWF, it’s run out to one month twice a week. Note the below average upper-level heights for the next 2-4 weeks!
Rose Festival and Memorial Day are just around the corner! You can also see the cooler than average weather on the 12z GFS and ECMWF 850mb ensemble charts. The green line is average for mid-late May, notice most of the time the temperatures are below average:
Models have attempted to throw up some brief ridging about next Monday, but I didn’t bite on that and only brought up the high temperature into the low 70s that day on our 7 Day Forecast.
