Heat is the main weather story

Very hot weather is the standout in Richardson, with conditions already feeling uncomfortable this afternoon and the temperature expected to climb near 100F today. The air temperature is 91F, and it feels like 92F. Relative humidity is 38%, with a dew point of 63F.

Skies are clear, and the wind is 8 mph with gusts to 10 mph. That combination is keeping the weather dry and bright, but it is not enough to offset the heat for anyone spending extended time outdoors.

Today, tonight and tomorrow

Today stays sunny, with a high near 100F and a 0% chance of precipitation. The National Weather Service forecast also indicates heat index values as high as 102. South wind is expected at 5 to 10 mph.

Tonight remains clear, with a low near 81F. Heat index values may be as high as 101, and south wind is expected around 10 mph.

Tomorrow brings more sun and another high near 100F. The chance of precipitation is 14%, and heat index values may again reach as high as 102. South wind is forecast at 5 to 10 mph. The low tomorrow is near 80F.

Alerts and heat safety

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

Even without an alert, this level of heat can wear people down quickly. Drink water, take breaks in shade or air conditioning when possible, and try to limit strenuous outdoor activity during the hottest stretch. Check on people who may be more vulnerable to heat, and keep pets supplied with water and a cool place to rest.
