Timing and Overview:
An upper level storm system and Pacific front will move across Texas Friday night and Saturday and interact with plentiful moisture and instability to result in showers and thunderstorms, some of which could be strong or severe. Isolated storms will form across West Texas Friday afternoon and move into the Edwards Plateau Friday Night. These storms could produce large hail and damaging winds as they form into a line along the front.
The complex of storms will march eastward across the area Saturday with the continued threat of large hail and damaging winds. While these will be the main threats, if any isolated supercell storms are able to form out ahead of the line of storms these could pose the risk of an isolated tornado.
In addition to the severe threat Saturday, locally heavy rainfall will be possible from the stronger storms. The front should be through most of the area by Saturday evening, and east of the area by early Sunday morning, ending the rainfall and severe threats.
