National Weather Service guidance and ensemble model consensus point to a June 14 high in Houston near 90–93 °F, with the market’s tight split between the 90–91 °F (37.5 %) and 88–89 °F (33.5 %) bins reflecting uncertainty over afternoon convective timing and coverage. A warm, moist Gulf airmass supports morning insolation and rapid warming from dew points in the mid-70s, yet scattered thunderstorms developing after 1 p.m. are expected to increase cloud cover and limit peak heating. Historical normals for the date stand at 92 °F, but any earlier or more widespread convection would suppress readings into the upper 80s while delayed storms could allow a brief push into the low 90s.
