It’s officially the wettest October in the Dallas-Fort Worth area since records have been kept, and more rain could be on the horizon.
The National Weather Service in Fort Worth reported Thursday morning that 14.51 inches of rain had fallen at DFW Aiport through Wednesday, beating the previous record of 14.18 inches set in 1981.
That comes in the midst of the wettest fall on record in North Texas.
“We went from a situation where we had a lot of high pressure a couple months ago that shifted off to the east and opened the area up to a trough of low pressure,” meteorologist Lee Carlaw said. “It allowed extremely high moisture to work its way back into the area.

“Really, to get the prolonged moderate rainfall we’ve had, you need low-level moisture and that mainly comes from the Gulf of Mexico,” he said.
Hurricane activity played only a minor role in October’s rainfall, Carlaw said.
The month could close out with a stormy Halloween, padding the record-breaking total, he said.
“It’s looking like a pretty potent upper-level storm system will descend with a cold front coming through the area Wednesday and into Thursday, but that’s still a little far out in the forecast,” he said.
2018 is now the seventh-rainiest year since records have been kept in the area, according to the weather service. But the 49.41 inches that have fallen so far pales in comparison to 2015, when we recorded 62.61 inches.
“It’s tough to say” whether beating the all-time record is possible this year, Carlaw said.
“You saw over the past month how easy it is to pick up a quick 6 to 10 inches of rain, but typically we don’t see systems like that fall over wide areas.
“It certainly looks like it’s going to be a pretty active weather pattern over the next several weeks, but it does look like it will be less wet,” he said.
One upside of the torrential rains has been that the bad drought conditions from the summer have been washed away.
“We went from D4 (extraordinary drought) to basically nothing. You have to put up with a little flooding for a while, but at least some good did come out of it,” Carlaw said.
