North Texas is heating up quickly this week as the upper-level low that brought in cooler, unsettled weather last week continues to drift east. As the ridge of high pressure expands, North Texas will get its first "heat wave" of the year.

An early-season heat wave is set to bake huge swaths of the country with record or near-record high temperatures expected across the northern and the southern Plains, the Southwest and much of central and southern Texas.
