All I know about Oregon weather is from Grants pass, driving through the grass farms mid state where it always seems rainey and Portland where weather comes either warm and wet or cold and wet....

I built cabinets professionally, and didn't bother with tolerance. Just cut all the horizontals at the same time without changing the table setting.

Otoh, at the sheet metal place, with a 5 ton male pattern 9 foot diameter, 10 degrees of warmth would make almost .25" oversized parts.
