Narrative:

Held for 45 mins over heatr intersection on ukw 9 arrival and then was notified that dfw was 'now open' and accepting arrs. (Thunderstorms had closed the field.) airport was reporting 53 KT gust while we were on downwind; so we agreed that we would not land if the winds did not improve and also that the captain would fly the approach. We xferred controls at around 11000 ft. Winds/gusts lessened and captain flew approach to runway 36L at dfw. Wind shift from passing thunderstorm caused too much of a tailwind to land to the north. At approximately 1800 ft MSL; captain executed a go around to 3000 ft MSL. Notified captain with 1000 ft to go call out; and approaching 3000 ft AGL; I called out 3 times to level off and touched his hand to signify to level off. Captain later stated he had 10 degrees nose down and idle thrust and was unable to level at 3000 ft. I notified ATC that we needed a higher altitude and that it was 'very rough at 3000 ft' but by this time we were approximately at 3600 ft. As we were correcting to our assigned altitude of 3000 ft; ATC responded with a climb to 5000 ft. Flew outbound to the north and returned to an uneventful landing on runway 18R. We discussed the event further on the ground and the captain believed that we were caught in an updraft with moderate turbulence from the preceding thunderstorm. No TA/RA occurrences.

Title: AIR CARRIER; EXECUTING A GAR; ENCOUNTERED TURB AND SUFFICIENT UPDRAFT TO PREVENT THE FLT CREW FROM LEVELING AT THE ASSIGNED ALT.

Narrative: HELD FOR 45 MINS OVER HEATR INTXN ON UKW 9 ARR AND THEN WAS NOTIFIED THAT DFW WAS 'NOW OPEN' AND ACCEPTING ARRS. (TSTMS HAD CLOSED THE FIELD.) ARPT WAS RPTING 53 KT GUST WHILE WE WERE ON DOWNWIND; SO WE AGREED THAT WE WOULD NOT LAND IF THE WINDS DID NOT IMPROVE AND ALSO THAT THE CAPT WOULD FLY THE APCH. WE XFERRED CTLS AT AROUND 11000 FT. WINDS/GUSTS LESSENED AND CAPT FLEW APCH TO RWY 36L AT DFW. WIND SHIFT FROM PASSING TSTM CAUSED TOO MUCH OF A TAILWIND TO LAND TO THE N. AT APPROX 1800 FT MSL; CAPT EXECUTED A GAR TO 3000 FT MSL. NOTIFIED CAPT WITH 1000 FT TO GO CALL OUT; AND APCHING 3000 FT AGL; I CALLED OUT 3 TIMES TO LEVEL OFF AND TOUCHED HIS HAND TO SIGNIFY TO LEVEL OFF. CAPT LATER STATED HE HAD 10 DEGS NOSE DOWN AND IDLE THRUST AND WAS UNABLE TO LEVEL AT 3000 FT. I NOTIFIED ATC THAT WE NEEDED A HIGHER ALT AND THAT IT WAS 'VERY ROUGH AT 3000 FT' BUT BY THIS TIME WE WERE APPROX AT 3600 FT. AS WE WERE CORRECTING TO OUR ASSIGNED ALT OF 3000 FT; ATC RESPONDED WITH A CLB TO 5000 FT. FLEW OUTBOUND TO THE N AND RETURNED TO AN UNEVENTFUL LNDG ON RWY 18R. WE DISCUSSED THE EVENT FURTHER ON THE GND AND THE CAPT BELIEVED THAT WE WERE CAUGHT IN AN UPDRAFT WITH MODERATE TURB FROM THE PRECEDING TSTM. NO TA/RA OCCURRENCES.
