Texas is set to experience unusually warm weather through Saturday, with temperatures expected to soar into the 80s and 90s—a significant 10 to 20 degrees above the average for this time of year. Several cities in the southern part of the state may even break existing record highs before a dramatic shift in weather patterns occurs. Late Sunday, a powerful Arctic front is forecasted to sweep through the region, bringing with it a sharp cooldown. This front will effectively end the brief heatwave, ushering in much cooler and more typical November conditions by the start of the following week.
