Dallas is waking up to warm, heavy air today, with mid-morning temperatures already in the low to mid 80s and dew points parked in the low 70s. The National Weather Service is calling for a mostly sunny afternoon with a high near 97 and heat index values that could push into the low 100s. There is no heat advisory in effect this morning, but forecasters say the heat will build through the weekend into the upper 90s and low 100s.
Afternoon Heat and Humidity
Sunshine and a south-southwest breeze around 5 to 10 mph are on tap this afternoon, with temperatures topping out near 97 and holding in the mid 90s later in the day. Humidity will add some sting, with heat index values around 100 to 103 possible during peak afternoon hours. See the full forecast from the NWS Fort Worth.
Evening Storm Risk Near the Red River
A thunderstorm complex over the Plains may slide southeast into northeast Texas late this afternoon and tonight, with the best shot at a brief, gusty storm closer to the Red River. Any storms that clip the area could bring locally heavy rain and strong gusts. Lamar and Fannin counties picked up significant rain yesterday, which bumps up localized runoff concerns. Storms are expected to move faster than yesterday, which should limit widespread flooding, but brief heavy downpours and gusty winds remain the main threats.
Weekend Heat and South Winds
An upper-level ridge will lock in a dry, hot pattern for the rest of the week, pushing highs into the upper 90s and into the low 100s by the weekend. South winds are forecast to crank up, with sustained speeds of 10 to 20 mph and gusts up to 30 to 40 mph at times from Saturday into Monday. The breeze may take a little edge off the feel of the heat, but it could also complicate outdoor plans. Parts of North and Central Texas could approach or exceed heat advisory thresholds by the weekend.
Where To Cool Off
If the heat is too much, the city recommends using public libraries, recreation centers and other municipal facilities as cooling locations during business hours. Find an updated list and hours on the City of Dallas site, or call 2-1-1 for help locating services.
Quick tips: drink plenty of water, avoid strenuous activity during the hottest hours, and check on neighbors who may not have air conditioning. If you have outdoor plans tonight in northeast counties, keep an eye on the sky and be ready to head inside if storms start to roll in.
