From Brian Germ:
Outside of a few isolated showers across our western counties, expect another rain-free and warm night with lows in the upper 60s and lower 70s. Cloud cover should be on the increase by early Monday morning with some patchy fog possible. Winds will be light out of the southeast at 5 to 10 mph.
A strong upper-level trough over the western United States will continue to slowly move eastward for the start of the work week. The axis of lift and instability should remain nearly stationary Monday across West Texas, keeping the highest chances for rain and storms away from Central Texas. However, there will be low rain chances for our far western counties during the afternoon hours. Otherwise, expect more cloud cover but another warm day for much of Central Texas with highs in the upper 80s and lower 90s.
As the upper-level trough pushes out of the Rockies Tuesday, a cold front will begin to approach from the northwest. Isolated to scattered showers and storms will become more likely across parts of Central Texas from Tuesday through Thursday. The highest rain and storm chances are expected to be mainly west of I-35, where 1" to 2"+ of rain may be possible. Most other locations near and east of I-35 should see rainfall totals well under an 1" through the work week. Temperatures will lower due to the added cloud cover, chances of rain, and passing cold front. Afternoon highs should only be in the low to mid 80s by the middle and end of the week with morning lows in the 60s.
Lingering clouds and scattered showers are expected to be around Friday before conditions improve for the upcoming weekend. Drier air should arrive across Central Texas Saturday and Sunday, with highs remaining in the low to mid 80s. The morning temperatures are expected to be a little cooler, with lows in the upper 50s and lower 60s.
