While there will be many dry hours this weekend through next week, day-to-day or near day-to-day showers and maybe an isolated thunderstorm will be possible through next week. On Saturday, a weak shortwave could help to kick off some showers. Currently, we have low grade (20-30%) chance for showers on Saturday across much of the region. Sunday will be rain-free. Monday night through Friday of next week, an stronger more robust mid-upper disturbance could bring additional shower chances each day. Currently, we have low-medium (20-60%) chances for showers Monday night/Tuesday through Friday of next week. The highest chances for showers will be Monday night and Tuesday. Otherwise, expect for rain-free conditions to persist through next week.

Temperatures are expected to average out normal to warmer than normal through the balance of next week, courtesy of a narrow ridge of high pressure placed over the western Gulf.
