Recent National Weather Service guidance and ensemble runs from the GFS and ECMWF models place Dallas’s afternoon high in the upper 80s, keeping the 88–89 °F and 86–87 °F bins nearly tied in trader sentiment. Southerly winds near 15–25 mph are promoting mixing and modest warming, while scattered afternoon clouds and moderate humidity levels limit extreme surface heating. Minor differences in model timing for any weak frontal moisture or slight variations in boundary-layer mixing explain why probabilities sit so close between these two outcomes, with only small chances assigned to 90 °F or higher if skies clear more than expected.
