Narrative:
While being vectored for downwind at night to runway 23R in ind, noticed light rain showers developing in the area. ATIS called for higher broken clouds with wind down runway at around 15 KTS. On base, ATC asked if we could see the runway. There was a rain/snow shower between us and the runway, so we stayed with the ILS approach to runway 23R. On final, ride began to get bumpy so we added appropriate speed to our reference speed. As we entered rain/snow shower we developed and was moving through and the wind had picked up on the surface but was still down the runway. Started to get airspeed fluctuations and light to moderate chop. Was then advised that aircraft in front of us had a 10 KT loss in airspeed on final, then got amber increasing performance windshear warning. Then ride went to moderate to light turbulence loss. Performed the escape maneuver and went around. Initially gained about 20 KTS, followed by a loss of 10 KTS during escape maneuver. No loss in altitude. Told ATC we wanted to wait until WX cleared before starting on next approach. WX moved through very quickly and we landed uneventfully about 7 mins later.

Title: CAPT OF A SUPER MD80 PERFORMED ESCAPE MANEUVER AND WENT AROUND DURING FINAL APCH DUE TO WINDSHEAR WARNING AND AIRSPD FLUCTUATIONS.
Narrative: WHILE BEING VECTORED FOR DOWNWIND AT NIGHT TO RWY 23R IN IND, NOTICED LIGHT RAIN SHOWERS DEVELOPING IN THE AREA. ATIS CALLED FOR HIGHER BROKEN CLOUDS WITH WIND DOWN RWY AT AROUND 15 KTS. ON BASE, ATC ASKED IF WE COULD SEE THE RWY. THERE WAS A RAIN/SNOW SHOWER BTWN US AND THE RWY, SO WE STAYED WITH THE ILS APCH TO RWY 23R. ON FINAL, RIDE BEGAN TO GET BUMPY SO WE ADDED APPROPRIATE SPD TO OUR REF SPD. AS WE ENTERED RAIN/SNOW SHOWER WE DEVELOPED AND WAS MOVING THROUGH AND THE WIND HAD PICKED UP ON THE SURFACE BUT WAS STILL DOWN THE RWY. STARTED TO GET AIRSPD FLUCTUATIONS AND LIGHT TO MODERATE CHOP. WAS THEN ADVISED THAT ACFT IN FRONT OF US HAD A 10 KT LOSS IN AIRSPD ON FINAL, THEN GOT AMBER INCREASING PERFORMANCE WINDSHEAR WARNING. THEN RIDE WENT TO MODERATE TO LIGHT TURB LOSS. PERFORMED THE ESCAPE MANEUVER AND WENT AROUND. INITIALLY GAINED ABOUT 20 KTS, FOLLOWED BY A LOSS OF 10 KTS DURING ESCAPE MANEUVER. NO LOSS IN ALT. TOLD ATC WE WANTED TO WAIT UNTIL WX CLRED BEFORE STARTING ON NEXT APCH. WX MOVED THROUGH VERY QUICKLY AND WE LANDED UNEVENTFULLY ABOUT 7 MINS LATER.
