**Official National Weather Service forecasts for Austin on October 13 project daytime highs of 93–95°F under partly cloudy skies with southerly winds of 5–10 mph and low precipitation chances around 10%.** A persistent subtropical ridge aloft has sustained above-normal October warmth across central Texas, with recent model runs showing minimal cooling ahead of the date. Elevated dew points and humidity from Gulf moisture advection support heat indices near or above 100°F during peak heating, while mostly sunny conditions favor strong daytime warming. These dynamics position the 94–95°F and 96–97°F bins as the market leaders, reflecting trader alignment with the latest NWS point forecasts and ensemble consensus. Updated model runs and NWS briefings in the next 48 hours remain key variables that could shift implied probabilities.
