I don't know where you live but unless you have to ride in the winter rain I wouldn't. I have HAD to commute all winter long to work when I lived near boston. 10 mi each way. riding in 20degree weather is one thing but mid 30s with rain really stinks.
get some good windfron tights and light goretex jacket, shoe covers, good gloves
