We were flying to LGA. We got cleared to DIALS and 2;500ft for the Expressway Visual 31. The current weather was sustained winds above 20 knots with gusts going over 30 knots. There was also LLWS advisories for the field. We had been getting constant light turbulence with the occasional moderate chop potentially from about 5;000 all the way to the surface as well. The autopilot was turned off and we made the turn to go up the expressway and everything was going fine; just minor deviations. The Pilot Flying (PF) had to fight the weather conditions pretty thoroughly throughout the whole approach. We were a little high; so the Captain (PF) was making the corrections. When we wrapped around Shae Stadium; we were set up; slightly high and so adjustments were being made. When we wrapped around the stadium; the winds shifted from a tail wind to a headwind; and I think this gave us some issues. At one point I think we may have gotten slow for our set speed but the deviations may have been due to the wind shifts and gusts as well as wind shearing. We were focused on flying and I did not catch the speed exactly but I made a call about the deviation and PF made necessary adjustments. We landed smoothly like any other landing but I felt uncomfortable on the ground because I feel we may have gotten slower than expected. We had gone through a cloud earlier in the flight that gave us ICE PROT Speeds; even though the icing condition only lasted maybe a few seconds. We also added a few knots for the gusts. I think due to the wind shift and high energy speeds; the wrap around Shae Stadium was what ended up hurting us the most on the approach combined with it being a more advanced visual and the weather conditions on the field.
