TODAY
After a stretch of dry weather, our situation looks to improves starting today. A surge of moisture is sitting just off the Texas coast and as it slides into South Texas today, it should be enough to stir up isolated to scattered downpours. Rain chances sit at 40%, with the best odds during the afternoon.

SCATTERED RAIN SATURDAY
Rain returns on Saturday. Random, scattered downpours will develop area-wide. While it’s not a guarantee you’ll see rain, those who do could receive a quick half inch to an inch. Street flooding is possible. Lightning and gusty winds could accompany some of the heavier downpours. Otherwise, expect periods of sun, too, along with humid conditions.

The heat high shifts far to the north by early next week, opening the door for additional rain chances late Monday into Tuesday. Like this weekend, it’ll be in the form of scattered downpours. In this pattern, temperatures should stay below average.
