Returned reports (most recent first): 'METAR KDTW 231653Z 07013G20KT 10SM SCT027 BKN040 OVC070 18/11 A3039 RMK AO2 PK WND 10029/1635 RAE05 SLP292 P0000 T01780106', then 231553Z, then 231453Z. All three are type METAR (no SPECI in this window). The latest observation time at or before 231700Z is 231653Z, whose temperature/dew-point group is '18/11', giving air temperature = 18C. This matches the T-group tenths (T0178... = 17.8C rounds/truncates to 18 in the body group per standard METAR encoding). Answer: 18."
