My Wintyer Season Cycling Setup

Winter cycling in Baltimore County, Maryland; the only thing consistent is the sometimes hourly change in the weather making it more difficult to be prepared for the worse and always hoping for the best.

For example, wake up weather may be 28 F clear with low humidity, departure weather two hours later may be 45 F and overcast and just about 30 miles into your century it becomes misty with decling temperature and end with snow flurries.

How can a person be prepaired for all that, would it not be much slimpler to get on the indoor trainer and stay warm and dry?

For me even training rides help me understand myself a little more each time especially when things get adverse.
