 Decisions could come down later this morning. Well, the heat seems to come and go, and this time it's coming again with a vengeance as much of the south prepares for a broiling kind of weekend. CBS's Omar Villafranca is in Plano, Texas. Cities from Atlanta to Dallas could see temperatures in the triple digits heading into the weekend. More rain is in the forecast for areas around the edges of the heat dome, including the flooded states in the upper Midwest where more severe thunderstorms are ahead.
