It's totally possible with the right gear, time, attitude, skills and facilities to handle almost any weather scenarios. There are somethings that are a no-go, however, like ice-storms or maybe C-F combinations like night-time + heavy precip + extreme cold. These things can also be no-go for cars-- or should be.
