Rain expected to return to Dallas-Fort Worth on Wednesday

Rain returns to North Texas Wednesday afternoon, according to the forecast from the National Weather Service.

A strong upper-level trough developing over the Pacific Ocean is expected to create a surface low-pressure system over deep South Texas on Wednesday, said Dennis Cavanaugh, weather service meteorologist.

"That will stream some pretty good gulf moisture into the North Texas areas," Cavanaugh said.

But before that happens, the region will have been cloaked with cool air, with high temperatures Tuesday and Wednesday in the low 50s.

Cavanaugh, who works out of the weather service's Fort Worth office, explained that the moist, warmer air from the Gulf of Mexico will flow up over the cooler layer, once it reaches North Texas.

"That gives us the lift that will give us widespread rain shower activity," Cavanaugh said.

The trough was still off of the Baja Peninsula Tuesday morning. Therefore, Cavanaugh said, it will probably be Wednesday morning before North Texans begin to notice increased humidity in their region.

There is a 50 percent chance for showers Wednesday afternoon, according to the forecast.

"Past sunset, it will increase to 70 to 80 percent," Cavanaugh said.

Showers continue Thursday -- an 80 percent chance -- with slightly cooler temperatures in the mid 40s, the weather service said. Chances for rain decrease to 50 percent Thursday night.

"By Friday morning, rain chances will diminish," Cavanaugh said.

Friday, Saturday and Sunday will see intermittent clouds, but temperatures will be a little warmer, ranging from the low-to-mid 50s.

There is a 30 percent chance for showers Sunday afternoon and a 40 percent chance at night, while much of the population will be indoors watching the Super Bowl.
