Narrative:
Overall we attempted three approaches into ZZZ. First approach/RNAV 24: at the time we shot this approach winds were most favoring runway 24 out of about 280 gusting to 30-40 KTS with some reports of LLWS in the area by a dash 8 who had just recently landed. On the RNAV just inside the final fix; the aircraft was getting kicked around pretty good by gusts of wind; causing speed fluctuations of around 15 KTS. After a strong burst we went from being on speed; to getting the high speed clacker; to getting the stick shaker in a matter of seconds. I was a little stunned and slow to react; but the captain appropriately called for the go-around. When tower asked of our intentions we decided to give it another try. Second approach/RNAV 24: unfortunately; the second approach's conditions started to shape up and feel just as the first one did. After getting moderate turbulence with speed fluctuations outside of our stable approach parameters; I felt uncomfortable and called for the go-around. The captain promptly initiated the go-around profile callouts. After going around; wind reports and checks indicated that the winds were starting to favor runway 34. After assessing the landing data; terrain; and communicating with the dispatcher; we decided we had enough fuel to attempt the ILS to runway 34 and still be able to divert should we have to go-around again. Third approach/ ILS 34: the third approach had significantly less turbulence. It felt and looked much better. However; in the last few hundred feet we started to get strong gusts again. We got an amber windshear caution message; but appeared to be stable so the captain said [to] continue. At about 10-20 ft the windshear message went red. I was slow to react; because my head told me I should call for a go-around; but my gut was telling me we are stable enough to proceed 10 more ft down to landing. A low energy go-around at a mountainous airport in windshear conditions did not feel like a better option. The captain must have felt the same; and proceeded to land safely. It all happened very quickly.

Title: CRJ-200 flight crew's first two attempts at landing in gusty conditions with Low Level Windshear Alerts result in go-arounds. Third attempt; to a different runway; is successful despite windshear encounter near the ground.
