The triple-digit string in Dallas-Fort Worth is now only three days from an all-time record after another record high temperature on Tuesday: 107 at DFW Airport.
The record was 106, set in 1936 and tied in 1942. So far in August, temperatures have been 9 to 12 degrees above normal on average, according to the National Weather Service in Fort Worth.
On Tuesday morning, the temperature at the weather service's official reporting station dropped to 84 degrees, unofficially tying a record set in 1947 for the highest low temperature on Aug. 9.
There was a 10 percent chance of showers and thunderstorms Tuesday afternoon and evening.
Never miss a local story.
The DFW temperature reached 100 during the noon hour Tuesday to extend the streak of consecutive days with triple-digit temperatures to 39.
There have been 46 days of 100 or more overall in the summer of 2011. The streak record of 42 days was set in 1980, when the overall mark of 69 also was reached.
The heat streak record is appearing likely to be tied Friday as the weather service long-range forecast calls for high temperatures of at least 102 through then. As for breaking it, the forecast high for Saturday is for only 101.
