Moisture from Pamela is spreading across the mountains of northern Mexico into Texas and the southern Plains, where the threat of flooding will continue through Friday.
Flood watches are in effect from Texas into Oklahoma, as tropical downpours may lead to flash flooding.
San Antonio, Austin, Waco and Dallas are included in the threat area.
In addition, a powerful system over the northern Rockies and northern Plains is winding down, leaving behind temperatures that are well below average for much of the West.
Meanwhile, the East will feel temperatures well above average through the end of the week.
