I would like to re-caulk if possible. Does anyone know what this stuff is
called?

Dont' know what the old stuff is called but you will be using caulk
for the repair. Buy a high quality silicone caulk for that purpose.

Apparently it's too cold (-8 C / 17 F) to redo the caulking. I'm
going to wait till March. I think it will be warm enough then.

Is there really a break in the seal or did only the squeeze-out around
the frame come off the glass surface w/ time? Unless you have
actually had a failure of the window seal, I'd wonder if it would be
only a cosmetic "repair" you'll be making, not anything that will
matter functionally. And, if it is an actual leak path, how old are
the windows and were you original purchaser or was there a
transferrable warranty? Might be worth checking--some of the better
ones had pretty long warranty periods.

If you do need/want to go ahead, you can find black caulks suitable
for the purpose to at least reasonably match the color.
