From Rusty Garrett:
Gulf moisture is steadily increasing across Central Texas. Winds will remain out of the southeast at 5 to 10 mph overnight and into Friday morning, with lows only in the low to mid 60s.
After the possibility of a few light sprinkles Friday morning, expect about a 40% chance of scattered rain during the afternoon and early evening hours. Otherwise, highs Friday should reach the lower 80s with breezy southeast winds at times.
The start of the weekend will be warm and humid with highs in the mid to upper 80s on Saturday. Scattered showers and storms may be possible during the afternoon hours, mainly to the east of I-35. The main concern will be Saturday night and early Sunday morning as a strong cold front arrives. Rain and storm chances will be around 70-80% late Saturday night and early Sunday morning. A few strong to severe storms may develop with the main threats being hail, high winds and lightning. At this time, only a low threat for isolated tornadoes.
After the passing front, expect breezy north winds and clearing conditions by Sunday afternoon. Temperatures should stay in the low to mid 70s. A quiet and dry weather pattern will be in place early next week, with another front passing through the region on Tuesday. Expect highs to be in the low to mid 70s with mornings in the upper 40s and lower 50s.
