Squall line moving in from the north and I could see the ragged edges of the clouds. I informed the aircraft that I expected the winds to pick up shortly. About 45 seconds later the tower swayed and vibrated but the ASOS only reported 12kts on the wind. I informed Aircraft X that I was experiencing gusts and estimated them above 25kts. ASOS still reporting 12kts. A pilot holding short for departure reported possible wind shear at the approach end RWY 32; and I observed a large cloud of dust rising up from the field. Aircraft X conducted a go around and reported being 'bounced around really good'. I observed a decrease of 20kts radar indicated airspeed on the STARS. All of this took about 2 minutes of time; finally the ASOS reported wind 34019G28kts. We do not have direct wind reading instruments at Dothan! This placed a flight crew in a dangerous situation by not being able to get a timely and accurate reading of the wind.
Dothan Tower Controller reported winds gusting up to 28 knots which led to an aircraft going around. The airport was reported to not having direct wind reading instruments.
