So a few months ago I finally got around to building a weather generation system I was satisfied with. But that was just a beginning baseline, providing averages and not accounting for climactic and seasonal variations. I have been using what I developed during play and it has been working exactly how I wanted, just not really reflecting the proper climate of the game world. So here are updated charts for the Cfa climate(humid subtropical, it would apply to the southern coast of Brun around Thyatis, Karameikos, and the Sea of Dread generally); given that climate is defined by precipitation and temperature according to the Koppen Classification system the only charts that see any real changes are cloud cover(which determines precip) and temp. Though I did make a few other tweaks through playtesting. A big caveat here, the actual percentage chances of it raining or being hot or cold are not reflective of actual data, it's meant to reflect averages and the feel of what that climate is like.
