Houston weather: Storms possible on Sunday

High pressure is expected to build in Saturday, which will mean temperatures a little bit hotter and rain chances a bit lower. Look for a 20% chance for a few afternoon and evening showers and storms Saturday. Another disturbance will bring in a better chance for spotty to scattered showers and storms Sunday afternoon and evening. Watch out because a few of these storms could be on the strong side with hail, gusty winds and frequent lightning.
