The Electric Reliability Council of Texas (ERCOT) has issued a Weather Watch as arctic air plunges temperatures across the state, with freezing temperatures expected in many areas. Regions including Houston and Dallas-Fort Worth are bracing for a dangerous combination of bitter cold and the possibility of snow later this week. Meteorologists are sounding alarms over the conditions, highlighting that it has been nearly a year since Houston experienced temperatures this low. Officials across Central and South Texas are advising residents on how to prepare for the chilling weather, emphasizing the importance of conserving energy amidst increased demand. Preparations are also underway for potential winter storms, with snowfall predicted in West Texas and accumulations of 2 to 3 inches expected in other regions. Residents are urged to stay informed and take necessary precautions as the polar vortex impacts Texas.
