Traders assign the highest implied probabilities to overnight lows of 72–75°F in Austin on August 30, reflecting tight consensus among short-range models on modest radiational cooling under partly cloudy skies, light south-southeasterly flow, and elevated Gulf moisture that limits temperature drops. Current National Weather Service guidance and ensemble spreads highlight the key variables differentiating these bins: boundary-layer humidity, cloud cover timing, and any weak frontal boundary passage that could enhance mixing or suppress dew points. With August climatological normals near 74°F and recent model runs showing only modest day-to-day shifts, the market captures genuine forecast uncertainty rather than a single dominant signal, with resolution hinging on official observations at Austin-Bergstrom International Airport.
