National Weather Service guidance shows Austin's high temperature on April 5 clustering around 67°F following a Pacific cold front sweeping through Central Texas over the weekend, ending a run of 80s-to-90s highs earlier in the week after record-warm March conditions. Trader consensus, with 70-71°F at 25% implied probability edging 66-67°F at 24%, captures GFS and ECMWF ensemble spread driven by front timing uncertainties—if arrival delays into Sunday afternoon, enhanced diurnal heating under partial clearing skies could push toward low 70s, while persistent low clouds or showers post-frontal would suppress peaks to mid-60s. New 12z model runs expected today will clarify upper-air patterns and boundary layer mixing; historical April averages near 77°F provide climatological context but yield to current synoptic setup.
