Narrative:

Weather and thunderstorms were in the ZZZ area on our approach. We briefed and flew the ILS to xxr. On the approach; my first officer (first officer) got a little behind in configuring and I was late to prompt him to take different actions resulting in an unstable approach with the conditions we faced. I called for the go-around and my first officer executed it appropriately. Tower gave us a left turn and climb to 2000 feet. As we leveled off; there was a bit of confusion with the MCP/autopilot as it wouldn't engage. As we discussed what was going on with the automation; the airspeed started an insidious decay. My first officer started adding power to correct the decaying speed; but not quite fast enough. Then; very rapidly we apparently hit the outflow of one of the cells around us. We almost instantly lost 30 knots total around [recovery] speed. I took control of the aircraft when I saw 186 knots and falling; applied emergency thrust; and lowered the nose to get airspeed back. We kept the aircraft out of a stall; but as I got back to [recovery] speed and started to apply aft pressure on the yoke to level off/climb; tailwinds continued to increase and the stick shaker activated. Lessened the pressure on the yoke and gained more speed. We were able to initiate a climb at that time in heavy moderate turbulence. There was a cell in front of us and approach gave us a 060 heading to avoid weather. With the turbulence and 50 knots or so tailwind it was a bit of a struggle to get the airplane to turn. Eventually; I started to reduce climb passing 7000 feet MSL. We leveled at 8000 feet after we got out of the rough air.
