X2 on wind driven rain possibility. Most newer houses have a peak vent that runs along the top ridge of the roof. Occasionally, heavy rain with strong wind can cause some water to blow under the cap, and dribble/pour through the peak opening and into the attic.
Another possibility, though you should have seen already, is a large bees/hornets nest. Seen where a large nest was built on the floor of an attic, partially hidden by the insulation. Moisture inside the next drained to the bottom causing ceiling stains.
Poking a hole near the stains can A) maybe divulge more info and/or B) allow you better locate the location from the attic (stick something up through the hole).
