HEAT BREAK CONTINUES - Today's the last day of July, but you might not know it from stepping outside. A cold front that moved through yesterday brought much cooler temperatures. Yesterday's high only reached 86 at Decatur Municipal Airport, and today's forecast from the National Weather Service in Fort Worth calls for a high of around 75. A 40 percent chance of thunderstorms is also in today's forecast. High temperatures are expected to stay below 90 degrees through the weekend.
