Shortly after reinstating left engine bleed; 'left engine bleed light' and 'left engine bleed off EICAS' message illuminated. Followed aircraft QRH procedure and referenced aircraft MEL. Technician suggested 'left engine hpsov' was inoperative. After discussion with dispatch and chief pilot on duty; due to existing thunderstorms and forecast WX conditions along our planned route of flight; and direct impact aircraft anti-ice system declared an emergency with ZZZZ center and ZZZ ATC. Landed ZZZ overweight aircraft weight was 220300 pounds. After smooth landing flaps 25 degrees and no automatic-brakes stopped on runway while airport crash fire rescue equipment equipment inspected aircraft.
