Amarillo, TX – A scorching heatwave is set to grip the Texas Panhandle this week, with temperatures in Amarillo expected to break records by Thursday. Residents should brace for highs reaching the upper 80s to low 90s, particularly around Amarillo and Borger, where heat is forecasted to peak. This surge in temperatures, driven by a high-pressure system, will dominate the area through Thursday before a cold front brings some relief.
