Go for it, what's the worst that can happen?

J/k, seriously though, any situation you feel questionable about, seek out a local pilot that has experience with the weather etc... They should be able to give you some insight on the current conditions and what effects they'll have on you.

Feel free to PM me with any info/questions, I flew 135 freight for 2000hrs, and had my fair share of winter flying in Cessna 310's(ableit handled the weather better than any single-piston would)
