Texas on Saturday faces an upper-atmosphere wave of low pressure that could trigger storms and an increasingly deep flow of Gulf moisture.

In areas that see rainfall and increased cloud cover, temperatures are expected to remain below seasonal averages into next week, providing some relief from the summer heat. However, much of central and southern Texas, areas in the recovery phase from the catastrophic flooding, will face dangerous heat instead of renewed flooding.

Slow-moving storms will bring a risk of flash flooding to Texas both Saturday and Sunday. Here's where the greatest risk will be.

With hundreds confirmed dead or still missing, questions remain about the local response to flood warnings. Meanwhile, lawmakers will weigh measures to mitigate future disasters.

On Wednesday, hundreds prayed, wept, and held one another at a prayer service, among the first of many somber gatherings to come in the weeks ahead.
