Dangerous heat in McKinney as it feels like 101F this afternoon - Aug 6, 4 PM

*As of Aug 6, 4 PM local time.*

Heat is the main concern

Dangerous heat is the notable weather issue in McKinney this afternoon, with an air temperature of 97F and a feels-like reading of 101F. Skies are clear, relative humidity is 37%, and the dew point is 66F. Wind is moving at 11 mph, with gusts up to 14 mph.

The combination of hot air and a triple-digit heat index can put stress on anyone spending time outside, especially during prolonged activity. Even without a weather alert in effect, the heat is still worth taking seriously.

Tonight should be mostly clear. The low is expected around 79F, with temperatures rising to around 81F overnight. Heat index values may be as high as 101F. Wind should come from the south southeast at 5 to 10 mph.

Tomorrow and safety notes

Tomorrow is forecast to be sunny, with a high near 100F and a low near 79F. The chance of precipitation is 2%. Heat index values may again reach as high as 102F, with south wind at 5 to 10 mph.
