I live on the very north edge of the city of Dallas. As best as I can tell, the worst case scenario for here is heavy rain (4-8") and TS winds (40, gusting to 60). And the worst of it should be during the overnight hours Saturday night. Not fun by any means, but I expect the damage should be limited to a few downed tree limbs, and scattered power outages that last less than a day.

As you move South of I-20 and down towards Austin, the winds may be stronger (NWS says sustained 50, gusts to hurricane strength).
