Latest GFS/ECMWF ensemble guidance indicates robust WAA under a deepening thermal ridge, with 85th percentile deterministic runs consistently pushing Dallas highs into the upper 80s by April 29. Current synoptic pattern favors significant positive temperature anomalies. The 88-89°F target is well within the tighter clustering of model solutions. 75% YES — invalid if a shortwave trough introduces cloud cover.
