blistering heat wave that recently brought record-breaking temperatures to large sections of the southwestern United States, including several major cities, is forecast to continue this week as it tracks over much of the country on its way toward the East Coast. Meanwhile, meteorologists have warned that powerful storm weather could dump as much as a foot of rain, or more, on parts of Florida and potentially give rise to another round of tornado threats in central states. Metropolitan areas like Chicago may be affected by a possible twister.

“As we get to these first couple weeks of June, a lot of places are really starting to see those temperatures escalate,” Todd Shoemake, of the National Weather Service in Albuquerque, told the Associated Press on Monday. “Southern California, southern Nevada, southwestern Arizona, they’re starting to see lots of triple digits.”
