Heat and humidity lead the forecast

Dallas is in for a very hot, humid stretch, with today’s high near 102F and the air already feeling warmer than the thermometer shows. Current conditions are clear, with an air temperature of 82F and a feels-like reading of 87F.

Humidity is a major part of the story: relative humidity is 70%, and the dew point is 72F. Wind is 8 mph, with gusts to 14 mph. That combination is keeping the air muggy even before the day reaches its hottest readings.

Today, tonight and tomorrow

Today will be sunny, with a high near 102F and a 2% chance of precipitation. Heat index values may reach as high as 105. South wind is forecast at 5 to 10 mph, with gusts as high as 25 mph.

Tonight will be mostly clear, with a low near 81F. Heat index values may still be as high as 103. South southeast wind is expected at 5 to 10 mph.

Tomorrow stays sunny, with a high near 101F, a low near 80F and a 1% chance of precipitation. Heat index values may reach as high as 106. South wind is forecast at 5 to 10 mph.

Alerts and heat safety

There are no active NWS/NOAA weather alerts listed for Dallas.

Even without an alert, the heat and humidity are enough to warrant caution. Drink water, take breaks from strenuous outdoor activity when possible, and check on people and pets who may be more vulnerable to prolonged heat.
