As I've edged, I've made rules about weather. Min temp 25 degrees (32 if coming home in the dark and there's any chance of ice). Norain below 40 degrees. I've given up on dedicated rain gear, because it doesn't hold up, so I tolerate getting wet. I keep changes of clothes and dry shoes at work, so if I arrive wet, I can still go home dry. Often I'll carry clothes one way or the other in a messenger bag, which I carry half the time anyway to do errands on the way home.

As far as staying dry, as I said, no dedicated gear. But I wear a garbage bag (4mil --- nothing but the best). Since I losr a few pounds I'm now a perfect fit for a 40gal. size. The beauty of my fancy gear, is I don't have to worry about it getting dirty, losing it's waterproofing, or being at the wrong end of the trip, since I can stock a bunch of bags at each end.
