Most of Saturday will stay dry, although a few scattered showers and storms will be possible for the afternoon. If you do have outdoor plans, don't be shocked to see a shower pass through. Overall, the best chance for thunderstorms will come Saturday evening into early Sunday morning, as a cold front moves in from the west.
The Storm Prediction Center has highlighted much of our area under a risk for severe storms starting Saturday evening. Much of the area, including the City of Austin, is highlighted under an "Enhanced Risk" for severe storms, meaning numerous severe storms will be possible.
The main threats with these storms will be damaging winds and large hail. The tornado and flood threat, while not zero, are low.
Strong to severe storms are possible for parts of the Hill Country in the early evening and the Austin metro and to the east after sunset or about 8:00 P.M. local time.
As far as rainfall amounts, most areas should pick up less than an inch of rain. That explains why the risk for flash flooding with this system is low.
