Robust upper-level ridging is consolidating across the Southern Plains, directly over Texas, for April 29. High-res models (e.g., HRRR, NAM) consistently project 850mb temps spiking to +22°C to +24°C over Central Texas. This adiabatic warming, coupled with a subsident airmass and clear sky probability exceeding 80%, will drive surface temps. Expect a strong thermal low to deepen, pushing Austin's afternoon maximum well into the low 90s. 95% YES — invalid if a persistent shortwave trough disrupts the ridge.
