Discussion

Issued at 1045 PM CDT Thu Oct 29 2026

Lingering tropical moisture will support isolated to scattered showers overnight in the upper RGV and into the northern Ranchlands Friday. Drier conditions return Saturday through Monday, with temperatures gradually climbing from the upper 80s-mid 90s Friday into the low-mid 90s by Monday. A closed low moving into the Southern Plains early next week will bring breezy conditions Monday ahead of an associated cold front, expected to move through deep South TX Tuesday. Rainfall potential remains limited, with PoPs generally 30% or less across the northern Ranchlands and coastal areas. Cooler temperatures and drier air arrive Wednesday behind the front, with highs in the mid to upper 80s.

At local beaches, persistent easterly flow and elevated astronomical tides will continue to contribute to elevated water levels and beach erosion through the weekend. A Coastal Flood Statement will be extended through Saturday morning, with potential additional extensions.
