100-degree streak may end, but not for long

Forecasters say the string of 100-degree days in North Texas could end Tuesday, at 17.

But if the high does hit only 99, it will do nothing to make anyone feel better.

Today's high reached 102 at DFW Airport, marking the 17th straight triple-digit day, the eighth-longest streak of all time.

Throw in the humidity factor, and the heat index is expected to soar to 106 degrees.

The triple-digit heat remains in the long-range forecast at least through Saturday. If the streak holds until then, it would mark the fifth-longest in North Texas history.

The only good weather news is that August is halfway over.

"I don't know if you can call 99 degrees relief," said Jessica Schultz, a meteorologist at the National Weather Service's Fort Worth office. "We'll have a little bit more cloud cover holding down temperatures."

The mercury has topped the century mark every day since July 31, a string that makes ninth place on Dallas-Fort Worth's list of consecutive 100-degree days.

The undisputed champ remains the 42 days between June 23 and Aug. 3, 1980. In second place on the misery list is the 29-day streak of July 6-Aug. 3, 1998.

There's a 30 percent chance of rain today and tonight and a 20 percent chance Tuesday, with the best chance of storms along and north of Interstate 20.

"I wouldn't call it a cold front; it's more like a slightly cool boundary," Schultz said Sunday night. "It's really not going to be much of a change in the high-pressure air mass behind it

"Some of these storms could be strong. Some of these could be capable of 50 mph winds," Schultz said. "We had a few of these around the region Sunday, and we had a report of lawn furniture being blow around by 50 mph winds in Irving."

Even if the 100-degree streak ends, a new one is likely to start after Tuesday and continue through the weekend, Schultz said.

"We'll flirt between 99 and 100. It looks like we are locked into 100 degrees for at least the next week," she said.
