Heat wave to bake southern Plains, Texas into early week

Intense heat will remain centered over the southern Plains and Texas through early week, leading to a heightened risk of heat-related illnesses and poor air quality.
A ridge of high pressure has positioned itself over Texas, allowing hot air to build over the region.
On Saturday, San Antonio recorded its third 100-degree Fahrenheit day of the heat wave.
Dallas recorded its fourth 100-degree day of the year on Saturday. It is more typical for Dallas to have hit the century mark at least eight or nine times by early August.
Houston hit the century mark for the first time this year on Thursday as the high soared to 101 F.
High temperatures are forecast to reach or exceed the 100-degree mark each day through Tuesday in these cities.
“AccuWeather RealFeel® Temperatures will be between 105-110 each afternoon,” AccuWeather Meteorologist Isaac Longley said.
Similar RealFeel temperatures can be expected on at least several days in parts of Oklahoma and Louisiana.
“There will be little to no change in the overall weather pattern through early week, so dry, hot and generally sunny weather will prevail,” Longley added.
The combination of scorching sunshine, moderately high humidity and temperatures some 5-10 degrees above normal will increase the risk for heat-related illness for those spending prolonged periods of time outdoors.
Be sure to drink plenty of non-alcoholic beverages and take frequent breaks in the shade or an air-conditioned building to lessen these risks.
Cooling costs, which have been relatively low in the southern Plains this summer, will increase into early next week. Residents will be forced to crank up the air-conditioning units and fans, especially since low temperatures in the 70s and 80s will provide little relief from the blistering daytime heat.
By Tuesday or Wednesday, the high pressure will shift back into the Four Corners region, perhaps allowing some thunderstorms to arrive in the South Central states.
