Recent forecast models from the National Weather Service and global ensembles show high uncertainty for Austin's overnight low into October 2, with projected minima clustered in the upper 60s to low 70s amid widespread showers and thunderstorms. Persistent cloud cover, elevated humidity near 90 percent, and a wind shift from southerly to northerly flows are moderating temperatures while heavy rainfall could enhance localized cooling through evaporative effects. Historical October averages near 63°F provide context, but current steering patterns and model spread—particularly in convective timing—keep probabilities tightly balanced between sub-66°F outcomes and warmer scenarios above 80°F. Updated NWS briefings and next model runs will likely refine these ranges.
