Latest National Weather Service guidance and model consensus point to a Houston high in the mid-80s on June 15 amid widespread showers, thunderstorms, and elevated Gulf moisture, producing the market's tight clustering around 84–87°F. Overcast skies and convective clouds limit daytime solar insolation while evaporative cooling from rainfall further caps peak readings; any breaks in cloud cover or delayed storm initiation could allow brief warming into the upper 80s. The pattern reflects a weak frontal boundary and tropical moisture influx that has already suppressed temperatures below typical June averages near 91°F, with traders weighting the narrow range of possible maxima based on the latest forecast runs and timing uncertainties.
