Go-around for wind shear with possible severe turbulence. We briefed up the possible wind shear and gusty winds and I elected to use flaps 15 for the approach and landing. Final configuration was selected prior to the FAF at 2;400 feet. We were getting about plus and minus 10 kts on the ILS GP. At this time I was hand flying the aircraft to keep up with the speed changes and get a feel for the aircraft on final. As we passed 2;000 feet the airspeed was getting closer to +- 15 kts and the turbulence increased significantly followed by an uncommanded roll to the right to about 25 degrees of bank and an increase in aircraft pitch. I also saw the airspeed increase about 20 kts. I recovered the aircraft to wings level and was correcting to the Glidepath when we got the wind shear warning. We executed the wind shear recovery procedure then cleaned up the aircraft and followed the missed approach procedure. I reported to ATC the moderate to severe wind shear/turbulence. After contacting Dispatch we diverted to ZZZ1. I reported moderate to severe turbulence to ATC after completing the go around. After contacting Dispatch I elected to divert to ZZZ1. Upon arrival at ZZZ1 I discussed the event with Maintenance and based on the lack of buffeting; heavy G loading and rough movement of the jet I elected to not make an entry in the log book for severe turbulence.
Approaching ZZZ; aircraft rolled substantially and smoothly to about 30 degrees of bank. Nearly full deflection applied before aircraft stopped rolling. Aircraft pitched up and gave a windy shear warning. Captain went around and we advised FSS and company of moderate to borderline severe turbulence. Based on discussions with maintenance; write up was not entered.
Air carrier crew on final approach to a non-towered airport reported severe turbulence and wind shear. The crew executed a go-around and diverted to another airport.
