Narrative

ON FEB/XA/01; CAPT AND I WERE FLYING FLT INTO AZO A LITTLE AFTER XA00. I WAS THE PF UNTIL THE LNDG PHASE. OUTSIDE THE IAF; RECEIVED THE ATIS AND DID NOT STATE ANYTHING ABOUT PLOWING IN EFFECT; WHEN HE READ ME THE ATIS. VISIBILITY WAS ABOUT 2 MI WITH LIGHT SNOW. WE SET UP FOR THE LOC BACK COURSE RWY 17. AT THE FAF; CAPT MADE THE TFC RPT ON CTAF; THAT WE WERE UPJON INTXN INBOUND; ANYONE PLEASE ADVISE; AND NO ONE RESPONDED. I FLEW THE APCH DOWN TO THE MDA; THEN CAPT TOOK THE PLANE OVER FOR THE LNDG BECAUSE THE BRAKING ACTION WAS RPTED AS POOR. WHILE LNDG AND IN THE ROLLOUT PHASE; THE CAPT AND I NOTICED SOME DIM FLASHING LIGHTS WAY DOWN AT THE FAR END OF THE RWY AND OFF TO THE L-HAND SIDE. WE BOTH THOUGHT THAT MAYBE IT WAS JUST SOME CONSTRUCTION SIGNS OFF TO THE SIDE OF THE RWY AT THE FAR END. WE BOTH DID NOT FEEL THREATENED OR IN ANY DANGER AT ANY TIME; SO WE CONTINUED THE ROLLOUT. UPON ROLLOUT WHILE APCHING OUR TURNOFF; WE BOTH REALIZED THAT IT WAS A PLOW THAT WAS ON THE SIDE OF THE RWY AT THE FAR END. THERE WAS NOTHING ON THE ATIS OF PLOWING AND ZAU WAS NOT INFORMED OF SNOW PLOWING IN EFFECT.
