Narrative:
While enroute to okc; arrival ATIS noted ILS approaches were inoperative. While descending to 3000 feet we were cleared the visual approach to 35R. Weather was 2400 broken and 10 miles and hazy visibility. After descending through 2000 ft.; we received a GPWS 'obstacle' warning and immediately initiated a climb. Climbed several hundred feet; reestablished; and intercepted an approach path to runway 35R. Followed by normal landing.cause: in an our aircraft without the ability to use RNAV as a primary approach guidance. Suggestions: during post flight discussion with captain; in retrospect we should have backed up the visual approach with the RNAV approach for the vertical guidance to the runway.
