Elly Blue at BikePortland has a great article on cheap options for staying dry in the rain. Readers have also left lots of suggestions in the comments section.
If you are low on cash and need a pair of gloves to stay warm, I would suggest going to a hardware store and picking up a pair of winter gardening gloves for around $15. You'll look a tad goofy, but they were the warmest things that I wore during the winter of 2007.
