I think it is needle cast.  They spread fast on a couple of my pines.  Daconil is your friend.

From the pictures it doesn't appear to be dothistroma or needle cast, as the browning is from the inside out, not from the tip in.  Also, the description and timing are not consistent with either.

Can we get some better pictures, perhaps of the whole tree?

You might want to check with your local extension office.

I was able to get a few photos.  In the first photo, the black arrow points to where the half-yellow needles are.  Also, keep in mind that if you see some other brownish tips it is because I cut the needles in half in the fall because they were way too long since I had not started to do the decandling process on this tree yet.

Although, maybe I should mention....About two weeks ago, when it was about 50 degrees outside, I chopped off a nice size branch and patched it up with that cut paste.  You should be able to notice it from the photos.  Anyway, I kept the 6 inch branch that I cut off and brought it inside and noticed some very small black dots on it.  Then I noticed that some of them started to move.  I rinsed those off and then went outside to see if there were any on the rest of the tree and I couldn't find anything.  That's about it though.  Just figured I would let you know.

I finally found what was happening with mine, it simply was the soil drying faster than expected for the season. The tree did sacrifice a few branches by letting them dry and has bounced back to growth mode now that I increased the watering.
