Carlisle United defied the snowy conditions to sweep aside Sheffield Wednesday and progress to the Johnstone's Paint Trophy area final.
Francois Zoko headed in the opener after Tom Taiwo's floated cross picked out the unmarked striker, before Lubomir Michalik crashed in a volley.
Ben Marshall then latched onto Gary Madine's pass to chip Nicky Weaver for the home side's third.
The Owls struggled to reply with Darren Purse's header only a mere consolation.
Despite the heavy snowfall, the game survived the cold snap, though it was a close call, with pitch markings being dyed blue and fans having to park in a local industrial estate due to the frozen parking facilities at Brunton Park.
Zoko's well-placed headed goal warmed up the home fans in a scrappy first half, while a bad-looking injury to Wednesday striker Neil Mellor saw him carried off on a stretcher following an innocuous challenge with Michalik.
Marshall's trickery was a constant threat to a fragile Wednesday defence in the second half, and when he combined expertly with Madine to force a corner, Michalik was on hand to thunder in a volley from inside the penalty area.
Both Zoko and Marshall had efforts cleared off the line before the latter took advantage of a sleeping Wednesday defence to flick Madine's pass over the on-rushing Nicky Weaver.
The visitors briefly awoke from their slumbers late on after Purse headed in Tommy Miller's corner, but it was too little too late, allowing last year's beaten finalists to set up a Northern Area final with either Tranmere or Huddersfield.
For Wednesday, the defeat ended a run of six straight wins, and represented the first game since it was announced Milan Mandaric had agreed to step down as chairman of Leicester City and take over at the cash-strapped Hillsborough club.
Carlisle United boss Greg Abbott tells BBC Radio Cumbria: "On our performances we've got just as much right to get out of the league as they have.
"We were better than them tonight, we deserved the win, and it's amazing psychologically we're up against a big team with big players and a big football club and we were the better side tonight in all areas.
"It's in contrast to Saturday [against Tamworth in the FA Cup] when all hell broke loose at half-time to make sure we didn't take life easy, that's more like the side we want to be and how we want to play.
