Narrative:

I was in a right pattern for runway at ZZZ practicing takeoffs and lndgs with a pre-solo student pilot. A low level broken cloud layer moved in rapidly from the northwest. When turning crosswind; we were heading directly for a cloud at 600 ft MSL. I took the controls and performed a climbing right turn toward a close right downwind. We did not enter the cloud; but were within 400-500 ft horizontal distance. We made that landing a full stop and shortly thereafter the field was IFR. To prevent the recurrence; I will be more vigilant of fast moving clouds in the traffic pattern.

Title: PA28 FLT INSTRUCTOR WITH A STUDENT RPTS AVOIDING FAST MOVING CLOUDS IN THE LNDG PATTERN.

Narrative: I WAS IN A RIGHT PATTERN FOR RWY AT ZZZ PRACTICING TKOFS AND LNDGS WITH A PRE-SOLO STUDENT PLT. A LOW LEVEL BROKEN CLOUD LAYER MOVED IN RAPIDLY FROM THE NW. WHEN TURNING CROSSWIND; WE WERE HEADING DIRECTLY FOR A CLOUD AT 600 FT MSL. I TOOK THE CTLS AND PERFORMED A CLBING R TURN TOWARD A CLOSE R DOWNWIND. WE DID NOT ENTER THE CLOUD; BUT WERE WITHIN 400-500 FT HORIZONTAL DISTANCE. WE MADE THAT LNDG A FULL STOP AND SHORTLY THEREAFTER THE FIELD WAS IFR. TO PREVENT THE RECURRENCE; I WILL BE MORE VIGILANT OF FAST MOVING CLOUDS IN THE TFC PATTERN.
