ACTIVE NEXT WEEK
The pattern becomes more active by Monday. Isolated storms are expected Monday evening. It’s impossible to know where a storm will pop up, but any storm that does will be capable of severe weather. By Tuesday, a weak front moving into North Texas will raise rain chances.

Again, timing and placement of any storm is impossible to know at this point, but severe weather is a possibility. Beyond that, rain chances stay with us, potentially through Memorial Day weekend.
