From Sean Bellafiore:
It's been a quiet week across Central Texas weather wise, but strong thunderstorms are in the forecast as we head into the weekend both on Saturday and Sunday. On Saturday, a stalled front, area of low pressure, and the dry line will positioned west of our area and will become the focus point to spark showers and thunderstorms during the afternoon. Those thunderstorms will move east during the late afternoon and evening hours into our area. The strongest storms will likely bring up to ping-pong ball sized hail, strong wind gusts, and frequent lightning. The best chance for strong thunderstorms will be from 3 PM to 10 PM with rain chances near 40%. High temperatures Saturday before storms arrive will likely reach the lower and middle 80s under partly to mostly cloudy skies.
As Saturday's storms dissipate during the overnight hours, a few isolated showers may form early Sunday morning. Overnight rain chances Saturday into Sunday remain low, near 20%, with overnight lows only dropping into the lower and middle 60s. The chance for showers and strong storms returns to the forecast Sunday with rain chances near 40%. Expect mostly cloudy to overcast skies throughout the day with high temperatures returning to the lower and middle 80s. If rain or strong storms were to pop up during the day Sunday, they'd likely form between 2 PM and 9 PM. Most of Sunday's rain should remain east of I-35. Higher chances for strong thunderstorms will lie in Northeast Texas. Rain chances Sunday will come to an end a few hours after sunset as dry air moves into Central Texas behind a cold front.
Overnight lows Sunday night into Monday morning should drop into the lower and middle 50s with the arrival of colder and drier air into Central Texas, but the bulk of the cold air will actually move in Monday night. With a delayed arrival of cold air, high temperatures Monday should still remain in the middle and upper 70s with strong north winds gusting to near 30 MPH under mostly clear skies.
Overnight temperatures Monday into Tuesday drop into the middle and upper 40s as cooler air moves in and with colder air in place Tuesday, high temperatures will struggle to reach the middle and upper 60s for the first day of Spring. After a cold morning Wednesday with morning lows in the lower 40s, temperatures should continue to increase through the week. Highs Wednesday return to the lower 70s but with the return of south winds Thursday and Friday, highs should climb back into the middle and upper 70s.
