Recent National Weather Service and model guidance for Austin shows partly to mostly clear skies and northerly flow on October 5, favoring radiational cooling after daytime highs near 82–85 °F and supporting overnight lows in the low-to-mid 60s. This places the daily minimum near the 61 °F threshold that separates the two leading market outcomes, with ensemble spread and minor differences in boundary-layer moisture or wind speed creating the near-even split between ≤61 °F and warmer bins. Persistent high pressure and dry air mass advection have reduced cloud cover relative to earlier runs, lowering the chance of a very warm night above 70 °F while historical October climatology (average low ~61 °F) keeps colder extremes unlikely without an unexpected cold-air surge. Updated model runs tonight and tomorrow morning will refine the exact minimum before market resolution.
