What is a heat dome? Scorching temperatures in Texas are expected to spread to the north and east

DALLAS - Scorching temperatures brought on by a ''heat dome'' have taxed the Texas power grid and threaten to bring record highs to the state before they are expected to expand to other parts of the U.S. during the coming week, putting even more people at risk.

''Going forward, that heat is going to expand ... north to Kansas City and the entire state of Oklahoma, into the Mississippi Valley ... to the far western Florida Panhandle and parts of western Alabama," while remaining over Texas, said Bob Oravec, lead forecaster with the National Weather Service.

Record high temperatures around 110 degrees Fahrenheit (43 degrees Celsius) are forecast in parts of western Texas on Monday, and relief is not expected before the Fourth of July holiday, Oravec said.
