I did manage to finally locate some older weather data from Fort Vancouver from 1833-34 from an old journal. Just barely avoided 90 there for the summer and then a frigid January in 1834 with the Columbia River frozen for three weeks and a monthly mean temperature of 27.8, with a monthly high of only 42. Thunder and snow on January 16.

The key to where we’re staying is intriguing.

Unfortunately no, I just have seen Jim reference the microfilm of it before. An interesting read on the early history of Seattle's weather observations though if you have time https://mrcc.purdue.edu/files/FORTS/histories/WA_Seattle_Conner.pdf

That new record for MPX was topped on tonight's 00z RAOB, with a very impressive 500 mb height of 6010 m, or 601 dm!

Gonna be a long and smoky fire season.
