Persistent cloud cover, widespread showers, and a shift to northerly winds from an active weather system are the main drivers keeping overnight lows in the upper 60s to low 70s for Austin on October 2. National Weather Service guidance currently points to a minimum near 68°F amid high humidity and limited radiative cooling, while some model runs allow for slightly warmer or cooler outcomes depending on rainfall timing and wind gusts. This uncertainty supports the market's near-even odds between sub-66°F and 80°F-plus bins. Historical October lows average around 58–63°F, but the current pattern deviates due to the stalled frontal activity and moisture. Updated NWS and NOAA model runs expected later today will likely refine the range before resolution.
