the Ides of October storm

It's not a real storm nowadays unless it has a name. The Weather Channel uses Norse and Greek gods, the NWS went with the calendar.

Here's the NWS Portland meteogram for our little spot on the map:

Top: clearly not a cold storm, but typhoon remnants generally look like this. Fairly warm downpours, so little range from high to low and not much space between temperature and dew-point.

Middle: here's the wind setup as it stands on Thursday night. After 4PM Saturday steady winds from the south in the mid-40s mph, and gusts to.. 67?  Wow: that's about 20mph higher than this chart for Portland, so our proximity to the low and our higher hillside location make a difference. In our specific case we're just on the north slope below a high point, so we'll hear limbs cracking on the 800' crest - hopefully none of them will impale our roof or our vehicles! The yard itself will probably feel the swirling wind to either side, but previous south winds have been blocked quite effectively. However: they were Not sixty-mile plus gusts on those occasions!
