Narrative:

Inside final approach fix encountered windshear caution. Fully configured plus 20 minus 10 knots. Event lasted maybe 10 seconds. Inside of 1;000 feet AGL aircraft popped well above glide path and high speed aural warning. Radar painting severe weather at opposite side of airport with the windshear caution cleared decided to aggressively control aircraft in the visual conditions to the runway causing a pull up from GPWS. I had full visual of the runway at all times and determined that the safest plan of action was to get the aircraft on the ground. The severity of the line of weather ahead would in my quick judgment have been extremely more hazardous than the unstable approach. I commend my non pilot flying for his great monitoring of airspeed and his help in this situation. I believe one aircraft made it in after us but I do not know the conditions they experienced on the ride in.I feel that this experience will have me going to an alternate before this happens again. We had aircraft making it in before us I felt the decision I made at the time was the correct one. I think we all need to be more active in weather avoidance such as continuous updates from dispatch during a flight into degrading conditions. I know it costs money but having nexrad installed on all aircraft would give us all the 'big picture' not just a 90 degree sweep of weather that is affected by ground clutter at such low altitudes.

Title: An air carrier crew on approach to IAH received an EGPWS WINDSHEAR alert with a 15-20kt speed increase and a flap overspeed. The approach was continued; even though unstabilized; because severe weather was visible at the other end of runway.
