From Brian Germ:
Temperatures have been meeting or surpassing the century mark over the past several afternoons. Expect that to continue one more time on Sunday before cooler and wetter conditions return. It will be another warm and quiet night Saturday evening around Central Texas, with overnight lows dropping into the middle and upper 70s under generally clear skies.
Another hot and mainly dry afternoon is expected for Sunday across much of Central Texas. Highs will once again reach the upper 90s and lower 100s with mostly sunny skies. The exception will be to the east of I-35 where a few isolated showers and thunderstorms are possible. There is only a low 10% to 20% chance for our eastern counties.
The strong upper-level ridge of high pressure that has been centered over the Central and Southern Plains for much of this last week will finally push to the west as a shortwave trough moves west across the southern states. This system will bring an influx of moisture back into the region for the beginning of the work week. Scattered showers and thunderstorms are expected around Central Texas Monday through Wednesday, with storms chances from 20% to 40%. Afternoon temperatures will be cooler due to the added clouds and increase in showers. Highs for the work week will only be in the lower and middle 90s.
A few isolated afternoon showers will linger into Thursday and Friday, but storm chances at the moment remain low at just around 10%. Temperatures will slowly increase by the end of the week and into the weekend, back into the middle and upper 90s.
