Dangerous Heat Conditions

The primary concern for Dallas this afternoon is the intense heat. The air temperature has reached 99 degrees Fahrenheit, but the combination of humidity and warmth means it feels like 103 degrees. Relative humidity sits at 35 percent, with a dew point of 66 degrees.

Winds are currently blowing from the east at 6 miles per hour, with gusts reaching 10 miles per hour. The sky remains mostly clear, allowing the sun to intensify the thermal load on the city. This level of heat index is considered dangerous, requiring residents to take extra precautions to avoid heat-related illness.

Today and Tonight Outlook

For the remainder of today, conditions will stay sunny with a high near 97 degrees. Temperatures are expected to fall to around 94 degrees in the afternoon, though heat index values may reach 102 degrees. East winds will range from 5 to 10 miles per hour, with gusts potentially hitting 20 miles per hour.

The chance of precipitation is minimal at 3 percent. Tonight, the sky will become partly cloudy. Lows will hover around 78 degrees, with temperatures actually rising to around 80 degrees overnight.

Heat index values could reach 99 degrees. East southeast winds will continue at 5 to 10 miles per hour, with gusts up to 20 miles per hour. There is a slight possibility of new rainfall amounts less than a tenth of an inch.

Tomorrow's Forecast

Tomorrow will bring a shift in weather patterns. A slight chance of rain showers is expected between 10 a.m. and 1 p.m., followed by a chance of showers and thunderstorms. The sky will be mostly cloudy, with a high near 92 degrees.

Heat index values may reach 98 degrees. South southeast winds will pick up, ranging from 5 to 15 miles per hour, with gusts as high as 25 miles per hour. The chance of precipitation is 30 percent, with new rainfall amounts between a tenth and a quarter of an inch possible.

Given the combination of heat and potential storms, it is wise to stay hydrated and limit midday exertion. Check on neighbors who may be vulnerable to the heat, and ensure you have a safe place to go if severe weather develops.
