Narrative:
On visual approach to 28L in boi. Aircraft was slightly overweight for landing. I requested a 10 mile final to burn additional fuel to ensure under max landing weight. We were told speed was at our discretion; so I configured the aircraft at flaps 35 to facilitate burning off fuel quicker. ATC turned us to base. As I verified we would be under 62;000 pounds upon landing; my airspeed was fluctuating due some turbulence. I was concerned with not over speeding the flaps. The first officer (first officer) had to call 'airspeed' twice to warn me speed was rising. We did not over speed the flaps. At this time; I called the field in sight. ATC cleared us for the visual to 29L. Still struggling to control my airspeed; I called for the first officer to set '4;000' in the altitude alerted for pattern altitude; which he did. Pattern altitude is 4;500 feet in boi. I called for the wrong altitude be set. I'm not certain I briefed the pattern altitude along with the approach brief. As I rolled final and was descending toward pattern altitude I got a ground proximity alert due to rising terrain in the area. I added power and increased pitch to begin a potential map. Just then the warning ceased. The terrain was in sight. The field was in sight. The aircraft was on the glide path and airspeed was stable; so I opted to continue the approach to landing. Be certain to brief visual pattern altitude and stick to it so that both pilots are on the same page when it comes to actually flying the pattern.

Title: Commercial Fixed Wing flight crew reported receiving a GPWS terrain warning on a visual approach to BOI.
