Washington state where the OP is from is having record heat this summer, they would go bad way to quickly, I would not want to take that chance with my family. I do this most of the winter, but summer is another story. I love to leave them on the counter and be at room temp ready to use also.
I live in Texas where every summer is a heatwave, and we can leave ours on the counter for at least a few days with NO problems whatsoever. And our house is not overly air conditioned - it's hot inside too. Just make sure to rotate the older ones to the fridge if they don't get used right away.
