Current Conditions and Heat Index
It is currently Thursday this morning in McKinney, TX, and the heat is already building. The air temperature stands at 81F, but the humidity is making it feel significantly warmer. The feels-like temperature is 85F, driven by a relative humidity of 74% and a dew point of 72F.
These conditions create a muggy atmosphere that can make the heat feel more oppressive than the actual air temperature suggests.
The sky remains clear, but the wind is picking up slightly. Winds are blowing from the south southwest at 8 mph, with gusts reaching up to 21 mph. While the breeze offers some minor relief, the high humidity prevents effective cooling. The National Weather Service notes that heat index values are expected to climb significantly higher throughout the day.
