Fort Worth, Texas – A brutal stretch of summer heat takes hold across North Texas beginning Thursday, July 17, with a heat index climbing to 105° by mid-afternoon in Fort Worth. Outdoor workers and drivers along I-35 and I-20 should prepare for intense sun exposure and rising pavement temps through early next week.
According to the National Weather Service in Fort Worth, highs will reach 97°F on Thursday and Friday, but humidity will make it feel several degrees hotter. South winds will provide minimal relief, gusting up to 20 mph. The dangerous heat is expected to last through at least Tuesday, July 22.
Areas like Arlington, Weatherford, and Grapevine will see similar conditions, with little cloud cover and no meaningful rain in sight. Cities along the I-35 corridor should anticipate daytime highs nearing or topping 100°F from Sunday into Monday. Nighttime lows will hover near 76°–78°, offering little cooling.
If you’re heading outdoors, avoid strenuous activity between 1–5 p.m., stay hydrated, and check on vulnerable neighbors or pets. Asphalt, playgrounds, and vehicle interiors will heat up rapidly. Officials urge residents to limit travel during peak heat hours and seek shade or air-conditioned spaces.
