Current Conditions and Alert Status

A Heat Advisory is currently in effect for Denton, Texas, signaling dangerous heat levels that require caution. The National Weather Service has issued this moderate-severity alert to warn residents of the intense thermal conditions expected to persist through the evening.

Right now, the air temperature stands at 81F, but the combination of heat and moisture makes it feel significantly warmer. The feels-like temperature is 84F, driven by a relative humidity of 70% and a dew point of 70F. Winds are blowing from the south at 7 mph, with gusts reaching up to 24 mph.

The sky remains clear overhead, offering no relief from the sun's intensity.

Forecast for Today and Tomorrow

Today will be sunny with a high near 104F. The heat index is expected to climb as high as 108F during the day. South southwest winds will continue at 5 to 10 mph. There is a 0% chance of precipitation, meaning the heat will remain unbroken by rain.

Tonight, skies will become mostly clear, but the heat will linger. Temperatures will drop to a low near 81F, though they may rise to around 83F overnight. The heat index will peak at 109F, making the night feel stifling. South winds will persist at 5 to 10 mph.

Tomorrow mirrors today’s intensity. Expect sunny skies and a high near 104F. The heat index will reach 107F. South southwest winds will remain steady at 5 to 10 mph. No rain is forecast, keeping the humidity and heat consistent. Temperatures will fall to a low near 82F tomorrow night, with the heat index hitting 108F.

Safety Reminders

Given the active Heat Advisory and the extreme heat index values, it is critical to prioritize safety. Stay hydrated by drinking water frequently, even if you do not feel thirsty. Limit outdoor exertion, especially during the midday hours when the sun is strongest.

If you must be outside, seek air-conditioned spaces whenever possible. Check on elderly neighbors or those without adequate cooling, as the high humidity and heat can pose serious health risks quickly. Do not leave people or pets in parked vehicles, as temperatures inside can rise rapidly to life-threatening levels.
