I'll take a walk in the snow and ground myself

Taking a walk in the forest (or meditating next to/under/with a tree) would do you more good for grounding.

I think I might have a little blockage in my sacral chakra, perhaps mostly. Is it enough to meditate and "feel" the area or?..

yes. focusing on that area untill you can feel as much energies churning there as elsewhere means removing the blockage.
