Dallas, TX – Triple-digit heat index values and a round of thunderstorms could complicate travel across North Texas on Wednesday, raising safety concerns ahead of the Labor Day weekend. Drivers should prepare for possible slick conditions, especially along I-35 during the afternoon commute.
According to the National Weather Service in Fort Worth, showers and thunderstorms may develop after 1 p.m. Wednesday. Highs will reach near 93 degrees, but humidity will push the heat index to 100. Gusty winds and brief heavy downpours could accompany the storms, though coverage will remain scattered.
Residents are advised to limit time outdoors during peak heat and to keep hydrated. Anyone traveling on I-35 or Highway 75 should allow extra time, as storms could cause delays and minor flooding in low-lying areas.
Storm chances continue Thursday with a 60% likelihood of afternoon thunderstorms. Winds will shift from the south at 5 to 10 mph, keeping humidity levels elevated. By Friday, scattered storms are expected again, with highs close to 89.
The upcoming Labor Day weekend will not bring much relief. Saturday and Sunday each carry a 30% chance of storms, with highs in the low-to-mid 80s. Monday, Labor Day itself, looks partly sunny with highs near 87, offering slightly drier conditions for outdoor events.
Residents should monitor forecasts daily as timing of storms could shift. Heat, humidity, and recurring storm chances will remain key factors through the holiday.
