My rain gear improved this year with the purchase of a cycling designed rain cape.

I got one big enough to drape over my hands, so they stay dry..

You need mudguards to stop wheel spray, I wear rain pants for windblown rain
And rubber Bean Boots.

if none, no fenders, you might as well just get a jacket.
and maybe some dishwashing gloves.

but TN didn't have a winter so I expect you wont need the same gear as I did .
touring Ireland where I lived in rain gear a Parka
from one of the outdoor shops might be better than a posh bike jacket..

Neon Lime, with wide reflective bands is a real bonus..
