Snow took out nearly a third of the day's play in Derby after Glamorgan's bowlers induced a mini-collapse.
Derbyshire's Wayne Madsen top-scored with 97 while Wes Durston hit 43 before the slump.
Spinner Andrew Salter was the day's most successful bowler (3-56) while Michael Hogan also claimed a third wicket of the innings.
Both teams managed to claim an extra bonus point in a short evening session as Derbyshire's tail-enders hit out.
Glamorgan spinner Andrew Salter told BBC Wales Sport: "It was a bit cold on the spinners' fingers, but in patches we did really well.
"I think that was one of the coldest days I've had to field.
"I was pleased to get the three wickets, it wasn't the most comfortable of feelings to start with, but I managed to get some rhythm towards the end.
"Leaking a couple of runs to Andy Carter at the end wasn't ideal, but it was a bizarre day with the snow."
