From Brian Germ:
The warm and quiet conditions are expected to continue through the remainder of the weekend. Temperatures Sunday morning will be in the lower 70s with some cloud cover around. Highs by Sunday afternoon should once again reach the lower and middle 90s under a mix of sun and clouds. Winds should be out of the south southeast at 10 to 15 mph.
A strong trough of low pressure and associated cold front will slowly progress eastward through the Plains by Monday and Tuesday. Cloud cover will be on the increase for Central Texas during that time as scattered showers and storms begin to increase across parts of West Texas. The front is expected to push through the region late Tuesday and into Wednesday, increasing our rain and storm chances in the process. Temperatures will lower in response to the added cloud cover and rain chances, as well as the frontal passage. Highs will go from the lower 90s Monday and Tuesday, to the lower and middle 80s Wednesday and Thursday. Rain and storm chances are expected to be highest, around 50%, for Wednesday and Thursday with the highest rainfall totals across western locations. No severe weather is expected at this time.
A few lingering showers may be possible on Friday as the front continues to push southeastward. Skies should be mostly cloudy with afternoon temperatures in the upper 70s and lower 80s. Overnight lows will also fall in response to the frontal passage, reaching the upper 50s and lower 60s for the end of the week. Skies are expected to continue clearing out Saturday and Sunday with near to slightly below average temperatures. Highs for the weekend should be in the lower 80s with morning lows in the upper 50s. Rain-free conditions are likely at this time.
