and typically unless you're a weekend warrior who can't pick their days noone really rides in the rain but it does solidify the snowpack as it always returns to a below freezing cycle after the front part of an unstable storm pushes in (the warm & wet)
30-32 degree "powder" (chowder?) does kinda suck and an be very draining physically cuz it really wants to throw you over the handlebars if you try and relax - but it is pretty rare, maybe 3-4 times a season.
25-28 degrees is alot more common out here and really its fucking great especially at the lower end of that scale. it does get tracked out tho (at resorts), and that too can be tough for people not used to it - especially if you aren't riding a stiff board that can knock that shit down.
if its below 20 and there is fresh the PNW is as good as it gets. except there's always the flats
almost everything we ride out here is a volcano so there are always some flat areas, either to keep your speed on at the resort, or to have to slog thru on the hike in in the BC.
