Yeah... 850mb temps seem out sync with the 500mb pattern on Saturday.

Funnily enough it looks like we'll be getting a backdoor Canadian cold front winter-style Friday into the weekend. Troughing intrudes just west enough to cool the upper levels and instigate mountain convection. For us though, it just means downsloping and very low humidity 60s under brilliant sunshine. Spokane could get some Arctic snow though. AI GFS has been bullish

It'll definitely be elevated stuff above the soupier, cooler pacific air. Most of the convection seems to be late overnight into tomorrow morning anyways so surface thermals are definitely off the picture. I don't even think we have any viable parcels now ahead of that marine intrusion

Looks like we have a marine intrusion tonight... and temps struggle to reach 60 tomorrow which seems like it would limit convection unless we have the thunderstorms over marine layer situation we have seen at times in the past.

NAM is initializing 1-400j/kg of midlevel CAPE broadly covering western WA now into tonight ahead of the shortwave. The evening sky is filled with altostratus and altocumulus (altocumulostratus???) indicating plenty of moisture. As weak as the forcing is, it's a pretty wet cutoff we're dealing with here. Given how slowly this feature will be moving, there is an opportunity for multiple squalls of heavier rain tonight, with a few rumbles of thunder. Funnily enough we'll probably be looking at less lightning and CAPE with these warm core towers than we did under the cold core CZ last week
