Houston, Texas – Scattered storms could cut into July 4th celebrations across Houston Friday afternoon, as a surge of Gulf moisture brings heat, humidity, and lightning risks.
According to the National Weather Service in Houston/Galveston, there’s a 40% chance of thunderstorms Thursday afternoon beginning around 1 p.m., especially impacting travel along I-45 and outdoor events in Harris County. Temperatures will climb to 94°F, but heat index values could soar as high as 106°F. Calm morning winds will pick up from the south around 5 mph by afternoon, increasing storm development potential.
Friday night and into the weekend, storm chances and humidity linger but skies clear slightly. Saturday remains partly sunny with a high near 93°F, offering brief relief for outdoor plans. However, rain chances return Sunday and ramp up by Monday, with a 50% chance of showers both days and continued highs in the low-to-mid 90s.
If you’re planning outdoor events or travel over the holiday weekend, avoid flooded streets during pop-up storms, drink water regularly, and limit exposure during peak afternoon heat. Storms may produce brief downpours and lightning, so have indoor options ready, especially during Thursday’s and Monday’s afternoon hours.
