Soaking Rain to Renew Flood Threat From Dallas to Houston This Weekend

Areas that dealt with significant flooding last weekend will experience an enhanced flood threat once again this weekend.

Heavy rain will soak central Texas on Friday and quickly shift to eastern Texas, Louisiana and Mississippi Friday night through Saturday.

One to 3 inches of rain, with locally 4 inches, is expected to fall across these locations.

Although these accumulations may seem insignificant compared to the totals from last weekend, it will be difficult for any rain to absorb into the extremely saturated ground.

Rivers that are elevated from last weekend's rain could easily overflow their banks from any additional rainfall.

If you ever encounter a flooded roadway, remember to turn around and find an alternate route.

Reed Timmer Highlights Entire Texas Flash Flood Chase From Patricia

While moisture from Patricia was to blame for last weekend's flooding, a storm system moving into the region from the Southwest is setting the stage for rainfall this weekend.

According to AccuWeather.com Senior Meteorologist Kristina Pydynowski, "This system will be making much more progress to the east than the complex system last weekend, which involved moisture from Patricia."

Pydynowski said that the quick-moving nature of this system will prevent a repeat of excessive rainfall totals as the upcoming heavy rain will not span more than one day in any given community.

"Regardless, with ground saturated after the recent rainfall, places along streams and in low-lying and poor drainage areas should prepare for possible flooding," Pydynowski said.

This could lead to travel disruptions and affect outdoor sporting events.

In addition, a few severe storms are possible on Saturday from Brownsville, Texas, into San Antonio and Houston. The main threat is damaging wind gusts, but a few isolated tornadoes are possible.

The rain will be beneficial in some respects, however, as it will continue to erase the drought that has plagued Texas.

Despite the quick-hitting nature of this system, rain could still put a damper on trick-or-treating across the lower Mississippi Valley Saturday night.

While the bulk of the rain will move farther east by Saturday evening, a few leftover showers will linger east of Houston and into Louisiana and Mississippi.
