Dangerous Heat and Air Quality Concerns

Denton is currently under the influence of a significant heat event, with the National Weather Service issuing both a Heat Advisory and an Air Quality Alert. The combination of soaring temperatures and reduced air quality creates hazardous conditions for residents today. Current readings show an air temperature of 99F, but the heat index makes it feel like 103F.

Relative humidity sits at 35% with a dew point of 66F. Winds are light from the south southeast at around 5 mph, though gusts have been noted up to 6 mph earlier. The sky remains clear as the city endures this intense heat.

The Heat Advisory is in effect until 8:00PM CDT today. During this period, temperatures are expected to reach a high near 103F tonight with a low around 83F. The National Weather Service notes that heat index values could climb as high as 105F during the evening hours.

There is a slight chance of showers and thunderstorms between 7pm and 4am, bringing a 20% chance of precipitation. Despite the potential for rain, the air quality remains poor under the separate Air Quality Alert issued earlier today.

Forecast for Tomorrow

Conditions will intensify tomorrow with temperatures climbing significantly higher. The high is forecast to reach near 108F, with heat index values peaking at 109F. In the afternoon, temperatures may drop slightly to around 106F, but the oppressive heat will persist.

Winds will shift to the south southwest, increasing to 5 to 10 mph with gusts as high as 20 mph during the night. Tomorrow night will see a low around 85F, with temperatures rising to around 87F overnight. The sky will be mostly sunny tomorrow with only a 10% chance of precipitation.

Given the extreme heat and poor air quality, residents are urged to stay hydrated and limit time spent outdoors during peak heat hours. Check on elderly neighbors and ensure pets have access to cool water and shade. Avoid strenuous activity during the afternoon when temperatures are highest.
