Weather; Human Factors
When we arrived at our destination; severe weather was approaching the field. On about a 10 mile final; ATC issued a wind shear alert warning; so we went around. Before we left ZZZ for Austin; we saw that there was weather moving toward the airport; so we added another 2;000 lbs of fuel for possible holding. We held at two different locations for at least an hour waiting for the weather to move; and we also knew that if we had to divert to our alternate; we would be stuck there because we would be out of duty. As the weather started moving off the airport; Austin Approach vectored us around the east side of the storm; to now approach the airport from the north. As we were approaching the final about 10 miles out; we experienced a possible lighting strike and severe turbulence that rolled the aircraft approx 70 degrees of bank to the right; all while clear of clouds. The autopilot was disconnected while recovering from the upset. We continued to the airport with only light to moderate turbulence the rest of the way in. There were no injuries to the passengers; and were grateful to us for getting them to their destination.
CE750 Captain reported a lightning strike; severe turbulence; and wind shear which resulted in a 70 degree bank while on approach to AUS.
