me: oh hey, it’s that weird part of the year where the days are hotter than the preceding summer and the nights are colder than the coming fall
me: does that mean we’re due for that one day of random hail?
Portland: that’s winter/spring, silly! It’s time for that one day of thunder without rain!
Is this the same dynamic as that random 100F weekend LA and SF get every September?
The fundamentals suggest that average summer highs are 110F. Except there’s a random 60F ocean right there so you get the breeze.
And then it gets juuuuuust cold enough the breeze stops.
A lot of weird Portland weather is cause it sits on the Columbia River Gorge (which was cut as the outflow path of an inland sea when an ice age ended and the glacial dam burst) and air is either channeled in from the cold sea or the hot inland dryland between the Cascade Range and the Rockies, or both at the same time and they run into each other, especially at the turn of the seasons.
As for California, I used to live in LA so I know about June Gloom and the Santa Ana winds and I’ve at least heard of the way SF is warmer in the winter.
Like, the American Standard Model of Weather is based on the eastern basins, the West Coast is really this strip between the mountains and the sea where shit gets weird
