Picked up a pair of Oxford waterproof gloves with a little bit of insulation in them - they're labeled as "summer" gloves but if I wore these in the summer my hands would be drenched. Also picked up a light windbreaker from Walmart for $20 that'll fit over my leather jacket in case it does rain.
Either way, the forecasts (I've been checking 5 different sites
) have changed and more or less converged to this:
Saturday morning - little to no precipitation
Saturday afternoon - minimal precipitation
Sunday morning/afternoon - chilly (just below freezing) but no precipitation
So I think with a little bit of luck, rain/snow shouldn't be any issue. Just gotta deal with the cold.
