*As of Aug 18, 5 PM local time.*

Severe Heat Warning Active

Dallas is currently under an Extreme Heat Warning issued by the National Weather Service. This severe alert remains in effect until tomorrow evening. The danger is immediate, with the air temperature sitting at 106F and the feels-like temperature also at 106F.

The dry air, indicated by a relative humidity of 21% and a dew point of 57F, means the heat is intense but not muggy. Winds are blowing from the south at 9 mph, with gusts reaching 12 mph. The sky is clear, allowing the sun to intensify the thermal load on the city.

Today and Tonight Outlook

The day is expected to remain sunny with a high near 105F. There is no chance of precipitation, and heat index values may reach 107F. As evening approaches, temperatures will drop to a low near 82F, though they may rise slightly to around 84F overnight.

The sky will remain mostly clear, and heat index values could hit 106F. Winds will shift to a south direction, ranging from 5 to 10 mph. This pattern of intense heat and dry air is consistent with the current severe alert status.

Tomorrow’s Forecast

Tomorrow will mirror today’s conditions, with sunny skies and a high near 105F. The chance of rain remains at 0%. Heat index values are expected to climb as high as 108F, making the perceived temperature even more dangerous.

Winds will come from the south southwest at 5 to 10 mph. Overnight, temperatures will again fall to around 82F before rising to 84F, with heat indices near 106F.

Given the sustained severity of this heat event, it is critical to stay hydrated, limit outdoor exertion during the hottest parts of the day, and check on vulnerable neighbors who may not have access to air conditioning. The combination of high temperatures and low humidity creates a significant health risk that requires constant vigilance.
