Dexter Blackstock volleyed the visitors into the lead after 18 minutes and although Albion were well below par, Forest displayed their true promotion credentials to send a clear warning to those fighting for promotion to the Barclays Premier League.
Radoslaw Majewski volleyed home a certain contender for goal of the season before Chris Cohen struck from the edge of the area to put Forest into a 3-0 lead by the 64th minute.
And although substitute Roman Bednar netted a consolation for the Baggies - the first goal Forest had conceded in almost nine hours of football - it was the East Midlands outfit who deservedly took the spoils.
Albion staff worked wonders ensuring the eagerly-anticipated encounter got the go-ahead as the wintry conditions played havoc with the rest of Britain's sporting calendar.
