Clear skies are giving Dallas a calm start today, but the quiet morning is a brief prelude to a dangerous afternoon. Temperatures are expected to surge to 107 degrees, with heat index values reaching 111. An Extreme Heat Warning remains in effect across North Texas through 8 p.m.
The National Weather Service Fort Worth office says the heat can sharply increase the risk of heat-related illness, especially during the hottest part of the day. Residents should move strenuous outdoor work to early morning or evening, drink water often, and take frequent breaks in air conditioning or shade, according to the National Weather Service.
Storm Chances Stay Limited Friday
Today will remain sunny through much of the afternoon, with only a slight chance of showers and thunderstorms after 4 p.m. The odds rise slightly Friday night before 10 p.m., but most of Dallas-Fort Worth is expected to stay dry.
The better chance for isolated storms is northeast of the Metroplex, where lightning and sudden gusty winds could briefly become a concern. Rain chances are around 10% Friday and 20% Friday night, so a storm may interrupt a few plans, but it is unlikely to provide widespread relief from the heat.
Ozone And Fire Risks Add To The Heat
Today is also an Ozone Action Day for the Dallas-Fort Worth area, with conditions expected to support unhealthy ozone buildup during the afternoon. The Texas Commission on Environmental Quality recommends reducing emissions by sharing rides, avoiding drive-through lanes, conserving energy and keeping vehicles properly maintained.
The heat is not going anywhere after today. Tomorrow could reach 107 degrees, followed by highs near 106 from next Sunday through next Tuesday, 104 next Wednesday and 101 next Thursday, while overnight lows mostly remain in the low 80s.
Dry grass, low humidity and mostly rain-free conditions will also increase the risk of wildfire starts through the weekend. Dallas-area residents should use extra caution with anything that could spark a fire, even as winds remain mostly light; gusts could reach 25 mph next Monday.
Heat Safety Remains The Priority
The most dangerous window will generally run from about 2 to 7 p.m., when temperatures and heat stress are highest. Never leave children or pets in a parked vehicle, and call 911 immediately if someone shows signs of heat stroke.
People without reliable air conditioning should plan time in cooled public spaces and check on relatives and neighbors who may be more vulnerable to extreme heat. Texas residents can dial 2-1-1 for information about nearby cooling centers and local assistance.
