There will be two upper-level systems that will be approaching the Lone Star State this week. This will coincide with a deep tropical air mass and potentially bring the highest rainfall totals we have seen all month long.
System No. 1
The first system is moving in from the Four Corners region and will bring our first round of showers and storms on Tuesday. The Storm Prediction Center has placed a majority of Central Texas under a "marginal" risk for severe storms on Tuesday. The main concerns will be heavy rainfall, strong gusts between 30 to 40 mph and hail.
Scattered showers and storms will start to develop on Tuesday afternoon, but computer models are showing a line of strong showers and storms pushing through late Tuesday night. Rounds of showers and storms are expected to continue into Wednesday.
High-resolution forecast models have started trending toward a strong line of storms moving through the Hill Country starting around 9 p.m. This band of storms is expected to continue pushing east throughout the overnight hours.
Residents along the Interstate 35 corridor, including Austin, can expect the strongest portion of the storms to move through around midnight.
Storms will push through our eastern counties early on Wednesday morning around 2 a.m.
Tuesday night won't be the only time Central Texas receives heavy amounts of rain. Another upper-level disturbance moves in for the end of the workweek and brings the potential for scattered to widespread showers and storms.
System No. 2
The second system will be approaching on Thursday, bringing the threat for additional rounds of heavy rain and strong storms through the weekend. This will be a concern for Weekend 1 of the ACL Music Festival.
We'll still have to iron out the specific timing for the multiple rounds of rain and storms as we get closer, but overall rainfall totals continue to trend higher, with 2 to 3 inches now possible for a good chunk of Central Texas. Isolated amounts could exceed 4 inches.
We need the beneficial rain after a very dry September, but we'll also have to keep an eye out for some flooding, especially late in the week as the dry soil becomes more saturated.
The forecast for this weekend is still subject to some change but, as of now, we're looking at a good bit of wet weather for the first weekend of the festival. The forecast could trend a bit drier by Sunday, but both Friday and Saturday are looking pretty wet.
The KVUE Storm Team will continue to closely monitor this developing forecast. In the meantime, the extended forecast can be found below:
