D10 CTLR EXPERIENCED OPERROR AT 3000 FT DURING STAGGERED APCH PROCS AND FREQUENT WX DEV OPS.

Narrative

TSTMS IN THE AREA AND ACFT WERE ARRIVING IN NON STANDARD DIRECTIONS. THE TWR HAD ASKED NOT TO LAND ANY ACR X AIRLINE ON THE E SIDE OF THE ARPT DUE TO GRIDLOCK. I WAS GETTING A FEED FROM 3 DIRECTIONS; AROUND THE WX FROM THE NW STRAIGHT-IN; W DOWNWIND FOR THE E RWY; AND E BASE LEG FOR THE W RWY. THE MD80 WAS #3 FOR RWY 18R. THE ACFT HAD BEEN VECTORED AROUND THE WX AND WAS ON THE LOC TO FOLLOW THE MD80 FROM THE E. THE ACFT WAS SLOWED TO 210 KTS; THEN 180 KTS; THEN 160 KTS. WE WERE LNDG S WITH A TAILWIND; 10 KTS ON THE GND AND UP TO 20 KTS AT ALT. I HAD MY 3 MI; BUT KNEW I COULDN'T KEEP IT TO THE RWY BECAUSE OF COMPRESSION. I TURNED THE ACFT OFF THE LOC FOR SPACING. THEN TURNED THE ACFT BACK TO STAGGER BEHIND THE TFC ON RWY 17C. I ASKED THE ACFT TO REDUCE TO FINAL APCH SPD (AROUND 8 DME). IT LOOKED LIKE IT WAS GOING TO BE CLOSE; SO I CANCELED THE APCH CLRNC; AND GAVE A TURN TO THE NW FOR RESEQUENCE. THE ACFT ADVISED HE/SHE COULDN'T TAKE THE TURN BECAUSE 'THERE IS WX BACK THERE.' (15 MI BEHIND THE ACFT.) DURING ALL THIS THE FOLLOWING MD80 HAD GONE THROUGH THE LOC. I TURNED THE ACFT BACK TO THE N FOR RESEQUENCE; HE/SHE DID SO WITHOUT QUESTION. THE ACFT WAS ABOUT READY TO JOIN THE LOC; THE PLT SOUNDED RATTLED; SO I CLRED THE ACFT FOR THE APCH; SWITCHED THE ACFT TO THE TWR. I DIDN'T HAVE STANDARD SEPARATION FOR A STAGGERED APCH. HOW COULD THIS HAVE BEEN AVOIDED? 1) LAND IN THE DIRECTION OF THE WIND. 2) GIVE THE TFC TO THE CTLR WORKING EACH RWY. 3) HELP THE TWR AS MUCH AS YOU CAN; BUT DON'T PUT THE ARR CTLRS IN A BAD SIT. 4) I MADE A ROOKIE MISTAKE; TRYING TO FIX SOMETHING THAT PROBABLY DIDN'T NEED FIXING. I SHOULD HAVE SWITCHED THE ACFT TO THE TWR AND LET THE FINAL MONITOR TAKE CARE OF IT. 5) THE SUPVR STANDING BEHIND ME TURNED AND WALKED AWAY WHEN I TOLD HIM/HER THE ACFT WOULDN'T TURN. NOT A LOT OF HELP.
