Weather
[We] encountered windshear on final approach. LGA was reporting IMC conditions on the current and forecasted weather as well as reporting using runway 13 for arrivals and departures. Our flight entered IMC conditions around at 12;000'. There was intermediate light chop till we reached the the outer fix of PAYMI at 3;000'. Here we intercepted the localizer to begin the ILS approach to 13. Once we reached the final approach fix; STEED; at 2;000'; we began to pick up continuous light to moderate turbulence. Around 1;000'; we encountered a flash of lightning followed shortly by the WINDSHEAR aural warning and visual display on our PFDs. Immediately; I initiated the windshear recovery maneuver and was out of the windshear by 3;000'. The published missed for ILS 13 is 2;000'; however; the recovery maneuver demanded more altitude.
CRJ-700 Captain reported executing a go-around after receiving a windshear aural alert on approach to LGA.
