Conviction is extreme for 84-85°F. Global ensemble suites are showing overwhelming consensus for a strong mid-level ridge axis building directly over the Texas Gulf Coast by April 28. GFS and ECMWF operational 2m max temperature outputs consistently bracket this tight range, with 70% of GEFS/EPS members printing values from 83°F to 86°F. The key driver is pronounced subsidence and sustained high-pressure dominance, ensuring maximum solar insolation under clear skies following a transient dry slot. While Gulf moisture advection will elevate dewpoints to low 70s, the lack of significant cloud cover and robust diurnal heating under the 500mb ridge will drive surface temps directly into the 84-85°F target. This isn't a statistical fluke; it's a structural atmospheric setup. Sentiment: Local NWS forecasts are escalating 'above-normal' temp probabilities, validating the model signals. 90% YES — invalid if max temp is <84°F or >85°F.
