A tropical disturbance over the Western Gulf has maintained a medium (50%) chance designation of development as it continues to move west-northwest over the next couple days. While this disturbance will bring some much needed rain to parts of the region, there remains a chance that this system could bring locally heavy rainfall to portions of Deep South Texas, regardless of development.

Heavy rainfall associated with Invest 98L could lead to isolated or scattered flooding, especially in urban and poor drainage areas on Friday.

Tropical moisture related to Invest 98L could bring locally heavy rainfall possibly enhanced by organized convection could lead to possible isolated to scattered urban poor drainage flooding to Cameron and Southern Hidalgo counties along the Rio Grande Valley on Friday.

Hot, humid, and mainly rain-free conditions are expected to persist Saturday through the middle parts of next week. There are some indications that there could be increased day-to-day rain chances mid to late next week and going through the end of August.

Today's high temperatures and rain chances.

Tonight's low temperatures and rain chances.
