Rain and thunderstorms on the way; severe storms possible

AUSTIN (KXAN) — A potent storm system is approaching from the western U.S. and will move across Central Texas Saturday. Increasing chances of showers and thunderstorms are expected between now and then.

By Saturday afternoon/evening, widespread rain and thunderstorms are expected, with some storms possibly severe. See the severe weather update from the National Weather Service below.

A 30% chance of showers is forecast through Friday morning, a 40% chance Friday, and 80% chance Saturday. Saturday’s storm will exit that night, leaving behind beautiful weather Sunday, with sunshine and highs in the 70s.

The storm system will likely bring some beneficial rain to many areas. Rainfall totals of 1/2 to 1 inch will be possible across the Hill Country to the IH-35 area, with amounts of 1 to 2 inches possible in areas east of the IH-35 corridor.

Statement from the National Weather Service:
…Strong to Severe Thunderstorms Possible across South-Central Texas Saturday Afternoon through early Saturday evening…
 
AREA OF CONCERN
All of South-Central Texas, especially along and east of Highway 281.
IMPACTS
  • Strong to severe thunderstorms with large hail, damaging winds and heavy rainfall.
  • Isolated Tornadoes with a few Supercells possible.
  • Rainfall totals of 1/2 to 1 inch. Isolated totals to 2 inches. Rain Rates of 1 to 2 inches per hour in heavier storms.
  • Mainly minor urban, nuisance type flooding for the San Antonio and Austin metro areas expected at this time. However, we will need to watch areas along and east of I-35 carefully for heavier rainfall amounts.
TIMING
Showers along with a few thunderstorms will likely be ongoing across most of South Central Texas Saturday morning. Thunderstorms will become more widespread through the morning hours across the Hill Country, and during the afternoon hours along the Interstate 35 corridor. Main impact time of this system will be from Noon to 6 PM Saturday as strong to severe storms move east across the area.
CONFIDENCE
Moderate to High.
DISCUSSION
An approaching upper level storm system will interact with increasing moisture from the Gulf of Mexico to produce widespread showers and thunderstorms across South Central Texas on Saturday. Light showers are already forming this afternoon over areas generally along and east of Highway 281…this will continue into Friday with a few isolated thunderstorms also forming. The chance for rainfall and strong to severe storms will be greatest during Saturday afternoon as forcing from an upper level disturbance moves across the region. Severe storms, some of which may be supercells, may produce large damaging hail, damaging wind gusts, and isolated tornadoes.
