Consider that if you merely plug the leak on the inside, you
guarantee some soggy wood; kinda limits your options. You really
want to stop it at the source.

To do that you need to find the gap where the water is entering, and
why. Could be trim or flashing missing, glazing probs, whatever.
Deal with that, and you have a "fix." With luck, you might even
be able to do that from inside, but don't count on it.

You might want to consult with a professional. Who might be
able to help you forestall similar probs elsewhere.

My son had a situation where melting snow was filling basement window
well with water and it was leaking around window into basement. I gave
him a container of plumber's putty and told him to apply to outside.
Provided temporary solution.
