The home fans were on their feet indulging in their latest rendition of "stand up and sing for Motherwell" when Lowry smashed in their deserved - and needed - second.
It sounds like a broken record, but what a time they're having. Their team are a joy to watch, and they found their groove in the Lanarkshire rain against United.
There are only a few hours left of the transfer window, and should they manage to keep a hold of Emmanuel Longelo, then that ought to be some of the best business in the land.
It boggles the mind that clubs - even in this country - haven't thrown money at the lung-busting left-back. He's been at the heart of the hectic start to the season, but is showing no signs of being leggy. Quite the opposite.
He could have had a hat-trick of assists such were the quality of his balls across the face of goal, while he cracked the post himself.
In a performance like this, though, it's unfair to single just him out. The goalscorers - all new boys - in addition to fellow fresh faces Jardell Kanga and Joe Hodge, look right at home here at Fir Park, and who can blame them?
The European dream may be over this term, but what a season the supporters of the Steelmen look set to have again.
