Heat is the main story

Dangerous heat is in place in Richardson this Wednesday afternoon, with the air temperature at 100F and the heat index at 103F. Skies are partly cloudy, relative humidity is 29%, and the dew point is 63F. Winds are 7 mph, with gusts up to 12 mph.

The forecast keeps the heat near the top end today, with sunshine and a high near 101F. The chance of precipitation is 1%, so rain is not expected to play much of a role. Heat index values may run as high as 105F, which can stress people spending time outside or in spaces without effective cooling.

Tonight and tomorrow

Tonight is expected to be mostly clear, with a low near 81F. The heat index may remain as high as 104F, so the warmth will not quickly fade tonight. South wind is expected around 10 mph.

Tomorrow brings another sunny, very hot day, with a high near 100F and a low near 80F. The precipitation chance remains 1%. Heat index values may reach 102F, with south southwest wind from 5 to 10 mph.

Alerts and safety

There are no active NWS/NOAA weather alerts for Richardson.

Even without an alert, this level of heat deserves caution. Drink water regularly, take breaks in air conditioning when possible, and limit strenuous outdoor work when heat feels most intense. Check on people who may have a harder time cooling down, including older neighbors, young children, and anyone without reliable cooling.
