"Head and body finely streaked with brown, underparts dull whitish with streaking across breast and along flanks, yellow edges to primaries and secondaries. Two thin buffy to white wingbars on median and greater coverts (greater coverts have yellow edges, and base of secondaries underneath is also yellow, so that when white to buffy windbars wear off the greater coverts, the bird can appear to appear to have a wide lower 'wingbar' is yellowish)." (Donald & Lillian Stokes's The Stokes Field Guide to the Birds of North America, p. 754)

This bird contrasts with the Yellow-Rumped Warbler in that the yellow here is on the wings and not on the body/sides of the bird. Note the yellow at the base of the tail..
