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.

We had a storm here about a week ago. The wind was roughly 80km/h (49 mph).
Water was leaking from the wood that surrounds the vinyl window. This is
the wood that touches the window. The actual leak inside was between that
piece of wood and the frame around the wall. The vinyl part of the window
wasn't leaking.

It seems that the caulk around the outside of window had failed because it
is cracking and in some places it is gone.

I figure the high wind that was beating on the window was driving the rain
into the small gaps? This is the first time that window has leaked. It was
rained before without any problems. It just seems that the high wind is the
only difference from other times it had rained.
