A heat dome is forming across the southern United States this weekend. This weather phenomenon is expected to cause temperatures to rise significantly in Texas.

As a result, parts of the state will experience their first 100-degree day of the year. The heat dome's impact will be felt across much of Texas, leading to triple-digit temperatures.

Further information about the heat dome and its effects on Texas can be found through local news sources, such as FOX 4 News Dallas-Fort Worth.
