Latest 00z GFS/ECMWF ensemble guidance for KDAL indicates robust ridging and warm advection. The 50th percentile of GEFS/ECMWF clusters consistently projects high-70s, specifically 76-78°F, for April 27th. The 74-75°F band is too restrictive given anticipated boundary layer mixing and post-frontal warming dynamics. Minimal probability for an exact hit within this narrow range. 90% NO — invalid if 12z runs universally trend below 76°F.
