Dangerous Heat and Humidity
Denison is currently under the influence of dangerous heat conditions this afternoon. The air temperature stands at 93F, but the combination of heat and moisture pushes the feels-like temperature to a hazardous 103F. This significant heat index value indicates that the body’s ability to cool itself through sweating is severely compromised by the atmospheric moisture.
Humidity levels are quite high, contributing to the oppressive feel. The relative humidity is currently at 53%, with a dew point of 73F. These conditions create a muggy atmosphere that can lead to rapid fatigue and heat-related illnesses for those spending time outdoors. The sky remains clear, offering no relief from the sun’s intensity. Winds are light, blowing from the north northeast at 6 mph with gusts reaching 8 mph, which is insufficient to provide meaningful cooling.

Today, the heat will persist with a high near 94F. There is a slight chance of showers and thunderstorms, with a precipitation chance of 18%. Any rainfall is expected to be minimal, with new amounts less than a tenth of an inch possible. Heat index values are forecast to reach as high as 100 during the day.
