The heat has been non-stop all summer and no relief is coming soon! Heat alerts are in place from the Gulf Coast to the Upper Midwest (above). A ridge of high pressure is expanding to the north and east, coming out of the Four Corners, and bringing the extreme heat with it. Heat alerts in the Plains continue through THURSDAY. Friday was another day of record setting highs in Texas. Wichita Falls reached 111°, beating out the old record.
