We reanalyze the extraction of the heavy Higgs boson signal $H\to W^{+}{W}^{-}\to \overline{\ell }\nu , \ell \overline{\nu }$, ($\ell =e or \mu$) from the standard model background at hadron supercolliders, taking into account revised estimates of the top quark background. With new acceptance criteria the detection of the signal remains viable. Requiring a forward jet tag, a central jet veto, and a large relative transverse momentum of the two charged leptons yields $\frac{S}{\sqrt{B}}>6\mathrm{}$ for one year of running at the SSC or CERN LHC.
