Narrative:
While on the dirty arrival descending through 13;000 ft; we experienced severe wake turbulence 6 miles in trail and 1000 feet above a B747. We notified ATC and requested to level at 12;500 feet and slow from 280 knots to 250 knots. We did that; continued arrival and landed without event.we experienced an undesired aircraft state. I believe the B747 was very heavy and the afternoon heat; lifting action and convective activity contributed to the wake turbulence.
