I am in North Texas, lost power between 11:30 and 12:30. Friends have had on and off 15 minute intervals, in Rowlett, Arlington, Carrollton and Lewisville. My boss in Grand Prairie has not. My work did, twice for 30 minutes.
With the super cold and everyone home, more power is being used than normal, and it doesn't help that venues hosting SuperBowl events are exempt either.
