Tuesday brought a drop in the oppressive humidity of the last few days, which helped to keep afternoon heat index values below 103 for much of North Texas. While humidity levels were not quite as high, temperatures were still above normal in the mid to upper 90s.
The trend for lower humidity will remain through the rest of the week. However, temperatures will continue to be above normal for the next few days. Highs on Wednesday are expected to be back into the mid to upper 90s.
Afternoon heat index readings will be from 100 to 102 through Friday, but a lack of high humidity will keep them from reaching higher levels. The weekend will feature heat index readings in the upper 90s.

Like recent days, the wind is going to remain quite light. This will lead to elevated pollutants and poor air quality. Because of this, an air quality alert has been issued for Wednesday. Those folks with respiratory issues should remain inside for much of the day.
HEAT SAFETY TIPS
Connecting you with your forecast and all the things that make North Texas weather unique.
With heat like this, you'll want to take precautions and be prepared.
Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors to ensure they stay cool.
Young children and pets should never be left unattended in vehicles. According to the National Safety Council, if it's 95 degrees outside the internal temperature of a car could climb to 129 degrees in 30 minutes. After just 10 minutes, temperatures inside could reach 114 degrees.
A child's body temperature heats up three to five times faster than an adult and heatstroke can begin when a person's core body temperature reaches 104 degrees. A core temperature of 107 degrees is lethal, according to the Texas Department of State Health Services.
Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heatstroke. Wear lightweight and loose-fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heatstroke is an emergency! Call 911. The CDC has more here on heat-related illnesses.
Take care of your pets by providing fresh, cool water and shade. Also, pets should not be left outside and unattended for too long. It's too hot and they need to be brought inside.
