National Weather Service forecasts confirm Houston's high temperature will reach the low to mid-80s°F today, April 13, propelled by a persistent upper-level ridge fostering southerly winds that advect warm Gulf of Mexico air masses. Midday observations at key stations like George Bush Intercontinental Airport already exceed 80°F, matching consensus from NOAA's high-resolution rapid refresh (HRRR) and Global Forecast System (GFS) models, which project peak heating this afternoon amid partly cloudy skies. This positioning reflects trader consensus on established meteorological patterns for mid-April, where climatological averages hover near 79°F but current synoptic setup favors above-normal warmth. Realistic challenges include unexpected marine stratus clouds capping insolation or isolated thunderstorms reducing solar input, though NWS guidance assigns low probabilities to such disruptions before evening. Updated hourly forecasts expected through sunset.
