Narrative:

We were on about a three mile final. The wind aloft was about 10 knots on our tail. As we passed the ridge the speed dropped off and we got a [stick] shaker. The speed returned as quickly as it bled off. The first officer advanced power and we accelerated passed our bugged speed. We continued the landing without any more deviations.we were at our final approach speed. The wind was not very strong but it was strong enough in this case to have the speed bleed off and cause a shaker as we crossed a ridge. We could have carried more speed. However the wind at the time did not seem to be fast enough to cause such a threat.
