Human Factors; Weather
During the final approach into the airport; as the captain asked for flaps 45; the airplane began to experience a sudden decrease in airspeed. The wind gust caused the autopilot to disengage and the stick Shaker to go off. As the captain assumed control of the aircraft and applied power; we received a windshear alert. Immediately the captain called for Max trust and followed the escape guidance. As the alert ceased; we advised tower of the go-around and windshear alert. We got vectors and came back around for another approach.Primary cause was the convective activity around the airport; and the windshear that caused a decreasing airspeed indication.When flying an approach into gusty conditions make sure to apply plenty of airspeed correction.
CRJ-200 First Officer describes a windshear encounter during approach to MKE with the Captain flying that results in stick shaker activation as flaps 45 are selected. The autopilot disengages and max power is called for. As the alert ceases the Tower is advised and the go around is continued and vectors received for another approach.
