Basement leaking between concrete foundation and sill

I have a small leak at my foundation sill coming into my basement. The exterior of my house is brick veneer with weep holes at the bottom. The weep holes are filled with what I would describe as rusted steel wool. The concrete foundation seems to bow out in the general area of the leak. By that, I mean that I can see about an inch of foundation jutting out from under the brick in that area, but it is not like that in other areas. Thought I'd mention that, though I don't think it would contribute. There is visible black plastic and what seems to be a bit of tar on the sill plate. The center of the leak in my basement is 65" from the wall. On the outside, there is a weep hole at 62" from that wall and a separation in the window sill above that area at 68". The cement window sill is separated into two pieces, since it's so long. There is obvious erosion in the mortar between these two pieces. I've attached a link to photos below. I just wanted to get some opinions on this before I start doing a bunch of stuff that may or may not be needed. We've been getting light drizzle all day. We've recently gotten serious downpours with no issues. Any help would be much appreciated. Thanks in advance.

Some photos from farther back on the outside would help.

But from what I can tell the poured foundation wall was done with a bow in it, creating a ledge. Control joints should be filed with backer rod and joint sealant, like vulkem 116 or Dymonic. Coat the ledge with BASF HLM 5000, but better not to cover he weep holes.

In the picture with the hose bib and extension cord, try and give us a picture of what you can see underneath the brick ledge. You might need to put a bright light on it for us to see.

Here are some more photos. Not sure if you can see under that ledge or not, but I can get a better pic later, if needed. As you can see, there are two large wet areas under that window, even though it's been dry for about 24hrs here. The rest of the brick on the house is not wet.

Well, I'm going to go with the most obvious source for the leak...the sill under the windows is no longer caulked to the window. One other thing to check, is crank open the side windows and see if the masterframe of the window (not the window sash) is coming apart at the miters, letting water down the crack and behind the brick.
