Narrative:

There was WX around the airport and the wind had just shifted from south to north. We received the ATIS and briefed the approach to land north on 35L with ILS. We were vectored to intercept the final course and set up the FMS to intercept and armed the localizer. After we were cleared to intercept, the copilot then noticed that we were overshooting the localizer course on his instruments and by the time I made the correction we had overshot final and approach called and vectored us back on course. I then noticed that I had set the inbound course to 173 degrees (south landing) instead of 353 degree (north). Contributing factors: I had set my mind to land south thunderstorms in area diverting my attention from raw data. Lesson -- monitor raw data more closely during coupled approach.

Title: HDG TRACK DEV DURING IAP ILS APCH.

Narrative: THERE WAS WX AROUND THE ARPT AND THE WIND HAD JUST SHIFTED FROM S TO N. WE RECEIVED THE ATIS AND BRIEFED THE APCH TO LAND N ON 35L WITH ILS. WE WERE VECTORED TO INTERCEPT THE FINAL COURSE AND SET UP THE FMS TO INTERCEPT AND ARMED THE LOC. AFTER WE WERE CLRED TO INTERCEPT, THE COPLT THEN NOTICED THAT WE WERE OVERSHOOTING THE LOC COURSE ON HIS INSTS AND BY THE TIME I MADE THE CORRECTION WE HAD OVERSHOT FINAL AND APCH CALLED AND VECTORED US BACK ON COURSE. I THEN NOTICED THAT I HAD SET THE INBOUND COURSE TO 173 DEGS (S LNDG) INSTEAD OF 353 DEG (N). CONTRIBUTING FACTORS: I HAD SET MY MIND TO LAND S TSTMS IN AREA DIVERTING MY ATTN FROM RAW DATA. LESSON -- MONITOR RAW DATA MORE CLOSELY DURING COUPLED APCH.
