Dallas Heat Alert: Temperatures to Reach 88°F Amid Wider U.S. Heatwave

Dallas will see a warm Tuesday with a high of 88°F (31°C) and partly cloudy skies, though the city will avoid the most extreme temperatures forecast for other parts of Texas. A 23% chance of rain exists throughout the day.

The heat in Dallas is part of a larger weather system bringing very warm air from the west to the eastern United States. This system also fuels intense storms in various locations across the country. While Dallas faces elevated temperatures, central and southwestern Texas are bracing for persistent rain and a growing risk of flash floods, particularly near the Guadalupe River.

Authorities recommend that residents stay hydrated and minimize prolonged exposure to the heat during the hottest parts of the day. The daily peak heat is expected around 2 p.m. local time, coinciding with the Spain vs. France World Cup 2026 semifinal match.

Meanwhile, a powerful high-pressure zone is set to drive an anomalous heatwave across the northern U.S., from the Great Plains to the Great Lakes. Temperatures in the northern Great Plains and Midwest could reach 95°F to 105°F (35°C to 41°C), potentially breaking daily records. The heat is also expanding into New England, with temperatures nearing 100°F (38°C), and will move into the Mid-Atlantic region by Wednesday.

If you are going to be out and about, make sure you are staying hydrated and limiting your exposure to the heat during the hottest parts of the day.
