A heat dome is forming over the southern United States, which will impact Texas this weekend. This weather phenomenon is expected to cause temperatures to rise significantly.

As a result, parts of Texas can expect to reach 100 degrees for the first time this year. The heat dome's effects will be felt across much of the state.

Further information about the heat dome and its impact on Texas is available from FOX 4 KDFW, a local news source in the Dallas-Fort Worth area, including Plano.
