Expect clouds around Uvalde and to the north—8,000 ft bases rising to 9,000 ft later in the day and 10,000 ft and higher over the hill country. Similarly high bases should predominate in the southern part of the task area; however, there may be few to no clouds in a large swath extending from San Antonio SW through the middle of the task area south of Uvalde.
