**National Weather Service forecasts indicate a high near 94°F for Houston on August 13, 2026, with a slight chance of afternoon thunderstorms that could limit further warming.** This aligns with the market’s heaviest weighting on 94–95°F (47%), followed by 96–97°F (26%) and 92–93°F (18.5%), reflecting trader consensus around official guidance rather than extremes. Houston’s subtropical climate typically produces mid- to upper-90s highs in mid-August under high pressure, with Gulf moisture and sea-breeze effects moderating peaks. Afternoon convection, common this time of year, often caps temperatures by increasing cloud cover and triggering storms, supporting the 92–95°F range. Recent model runs show limited variability, with no strong signal for a heat surge or significant cooling. Broader August patterns, including occasional heat advisories earlier in the season, provide context but do not override the near-term forecast consensus. Traders appear to treat the NWS outlook as the primary anchor, with lower probabilities assigned to 98°F+ outcomes that would require suppressed convection and stronger subsidence. Updated model guidance or storm timing on August 13 could still shift the final observed high within the 92–97°F window.
