Official National Weather Service forecasts for Houston on October 13, 2026, call for partly to mostly cloudy skies with a 40-50% chance of showers and thunderstorms, supporting afternoon highs of 91-92°F under persistent southerly flow and elevated moisture. High dew points near 75-78°F enhance heat retention while scattered convection and variable cloud cover introduce minor uncertainty in peak readings. These conditions align with the market's tight clustering around 90-93°F outcomes, as models show limited spread in maximum temperatures ahead of a stronger cold front expected Friday. Historical mid-October baselines near 85°F underscore the current anomalously warm pattern driven by the ongoing warm-sector regime.
