We study the observability of a standard-model-like Higgs boson at an upgraded Fermilab Tevatron via the mode h{r_arrow}W{sup {asterisk}}W{sup {asterisk}}. We concentrate on the main channel gg{r_arrow}h{r_arrow}W{sup {asterisk}}W{sup {asterisk}}{r_arrow}l{bar {nu}}{bar l}{nu}. We also find the mode q{bar q}{sup {prime}}{r_arrow}W{sup {plus_minus}}h{r_arrow}W{sup {plus_minus}}W{sup {asterisk}}W{sup {asterisk}}{r_arrow}l{sup {plus_minus}}{nu}l{sup {plus_minus}}{nu}jj useful. We perform detector level simulations by making use of a Monte Carlo program SHW. Optimized searching strategy and kinematical cuts are developed. We find that with a c.m. energy of 2 TeV and an integrated luminosity of 30 fb{sup {minus}1} the signal should be observable at a 3{sigma} level or better for the mass range of 145 GeV{approx_lt}m{sub h}{approx_lt}180 GeV. For 95{percent} confidence-level exclusion, the mass reach is 135 GeV{approx_lt}m{sub h}{approx_lt}190 GeV. We also present results of studying these channels with a model-independent parametrization. Further improvement is possible by including other channels. We conclude that the upgraded Fermilab Tevatron will have the potential to significantly advance our knowledge of Higgs boson physics. {copyright} {ital 1999} {ital The American Physical Society}
