**Forecast consensus from the National Weather Service and other models points to a minimum temperature in Houston on August 27 near 80–82°F, aligning closely with the market’s leading bins at 80–81°F (28.5%) and 82–83°F (28.0%).** Persistent high pressure centered over the region is maintaining hot, humid conditions with southerly to southwesterly flow that limits nighttime radiative cooling. Dew points in the low-to-mid 70s keep overnight lows elevated, while the urban heat island effect in Houston further moderates temperature drops. Scattered thunderstorms possible during the day on the 27th are not expected to produce widespread cooling or significant outflow that would lower the minimum below the upper 70s. Model guidance and official NWS forecasts consistently show the daily low in the 80–82°F range, with limited spread across runs. Historical August climatology for Houston features typical overnight lows in the mid-to-upper 70s, but the current ridge-dominated pattern has kept recent minima higher (upper 70s to low 80s). The tightly clustered market probabilities around 80–83°F reflect this strong forecast agreement, with lower-probability tails (e.g., 73°F or below at 25.5%) requiring an unexpected shift such as stronger storms or a transient boundary. New model runs and NWS updates overnight will provide the next key data points for traders.
