National Weather Service forecasts indicate Houston's high temperature on April 13 will reach the upper 70s to low 80s°F, driving trader consensus to an 84.5% implied probability for 80°F or higher amid persistent warm, humid southerly flow from the Gulf. Building high pressure from the east is expected to promote mostly partly cloudy skies during peak afternoon heating, supporting model consensus for highs near 81°F despite a 20-70% chance of scattered showers and thunderstorms that could suppress peaks to 78-79°F if coverage increases. This follows cooler early-April conditions around 65-77°F, with climatological April averages near 80°F providing baseline context. Traders await NWS's evening update and new GFS/ECMWF runs for refinements before resolution.
