ECMWF and GFS 00z/06z ensembles are showing robust upper-level ridging over the Southern Plains by May 6th, leading to significant thermal advection. Sustained surface heating under forecasted clear skies, combined with 850mb temps consistently pushing +25-26C, projects peak diurnal highs firmly into the 92-93°F target range. There's no significant frontal inhibition. 90% YES — invalid if a strong cold front clears the area by May 5th.
YES. GFS/ECMWF ensemble guidance shows 850mb temps spiking to 28-29°C with strong thermal advection under a persistent upper ridge. Expecting 92-93°F. 90% YES — invalid if pre-frontal trough accelerates.
GFS/ECMWF ensembles converge on 94F+. Robust upper-level ridge and dry advection virtually guarantee Austin exceeds 93F. NO is the only play. 90% NO — invalid if synoptic pattern shifts before EOD May 5.
