Dangerous Heat Conditions
The primary concern for Denison this afternoon is the intense heat. The air temperature currently sits at 97 degrees Fahrenheit, but the combination of humidity and solar radiation creates a feels-like temperature of 102 degrees. This level of heat index is considered dangerous for prolonged outdoor exposure.
Current relative humidity is 39 percent, with a dew point of 68 degrees. The sky is clear, and winds are light at 7 mph, though gusts are only reaching 6 mph. These conditions contribute to the rapid rise in perceived temperature, making it feel significantly warmer than the actual air temperature indicates.

There is a 42 percent chance of precipitation, with showers and thunderstorms likely to develop after 1 pm.
New rainfall amounts between a quarter and half of an inch are possible. Tonight will remain mostly cloudy with a continued chance of showers and thunderstorms. Temperatures will rise slightly to around 78 degrees overnight, and heat index values could reach 98 degrees.
