591 would bring mid 90s to PDX in the summer

Yeah it's pretty clearly not an intentional troll account. Your analysis here is spot on. I would be willing to bet that he genuinely has no idea how ridiculous some of his posts are.

A 41/17 spread at PDX would be insane considering that we don't have much cold to begin with. FWIW the 18Z AIFS also gets PDX pretty cold, with mid 20's at its lowest there. Curious if tomorrows models will look any different, and how long this inversion sticks around for. 4-5 days looks like the consensus but I bet that changes.

I'm going to go against the grain and say he's being dead serious. Now, assuming he's actually autistic, he's likely to be highly impressionable. You can see that when he took Eric Webb's tweet of a gut feeling and perceiving it as fact. Sometimes people with autism struggle with detecting underlying falseness or nuance. Or maybe he's using that as a scapegoat to post ridiculous content, but I doubt it personally. Anyways, it's been a cool but mostly dry day today. Got up to 48 here. Rains starting to roll in now.
