Aircraft X was handed off to me at 21;000 feet. I had identified prior to the handoff that the descent was probably going to be very difficult for the aircraft considering the ratio between the distance to the airport and number of feet necessary to descend 18;000 feet over about 40 miles. Upon initial contact I told the pilot to descend to 3000 feet which is the crossing altitude for the GPS approach. As the pilot got closer to the airport I decided to vector the aircraft northbound to accommodate the descent. Once the aircraft was in a better position to; altitude wise; make a stable approach; I turned them to a 090 heading. The aircraft was at about 8;700 feet in a 3;600 foot minimum vectoring altitude(MVA); 4.6 miles from a lower 2;100 foot minimum vectoring altitude. At about 7;000 feet; I turned the aircraft southbound on a 170 heading to point them closer to the initial fix for the GPS approach. Within the next couple miles the aircraft descended a lot quicker than I expected. By the time I noticed the aircraft was going to descend below the 3;600 foot MVA to 3;000 feet; it was too late. The aircraft was at 3;600 feet about 1 mile from the boundary; 3;400 feet .75 miles from the boundary; and 3;200 feet .24 miles from the boundary before exiting the 3;600 foot MVA into the 2;100 foot MVA at 3;100 feet.I should have acted quicker to stop the descent; though right up until it happened I thought the aircraft was going to stay high enough. We have seen this at the facility over the last few days. The aircraft are being handed off relatively late and very high. The weather was not very good and the winds aloft were making the aircraft faster than normal; so the descents have been difficult. A recommendation would be to delivery our northern satellite arrivals to us at a lower altitude.
A TRACON Controller reported an aircraft descended much quicker than anticipated and flew below their Minimum Vectoring Altitude.
