NWS Topeka issued this graphic earlier today suggesting the ongoing wet weather may not be over just yet in my neck of the woods...

Grrrr…Ruff Ruff…NO!! It needs to pour and be miserable on the 3rd thru the 5th. Sorry my dog just read your post and grabbed my phone for a minute. (It’s happened a few times now) I apologize for her rude reply.

Yep I'd say that's exactly right. You can see that there was pretty decent offshore flow at Astoria mid-month that then relaxed. With the next weak system there on the 25th mixing us out a bit, hence the quick warm-up, before the inversion reformed. Fun to have enough data to be able to recreate the regional weather patterns that far back!

Honestly doubt this “cold wet” pattern holds til the 4th but we will see. Glad to have some rain coming but hopefully no rain on the 4th. It can rain on the 3rd and 5th.

Great stuff! Impressive they pulled off an October shutout, and it looks like the rains didn't really get going that year until December. I'm guessing the abrupt temperature transition on the 21st reflected the relaxing of a persistent weak offshore surface gradient, allowing the inversion to form?
