DISCUSSION

Issued at 1222 PM CDT Fri Jun 26 2026

The 500mb ridge gradually works east across Texas this weekend and towards the Great Lakes by mid next week, pulling in a disturbance or two across the Southeast Atlantic coast into the northeastern Gulf by mid week. This will maintain warm, but seasonal temperatures, into the start of July and slowly start to re-introduce a low chance of rain into late next week, mainly along the coast or with the sea breeze, as easterly flow increases moisture under the ridge. Expect breezy southeasterly winds each afternoon through Monday, with wind gusts near 30-35 mph each day. There is a Moderate (level 2 of 4) Heat Risk every afternoon.

The main concern beyond heat will be an increased threat of life- threatening rip and longshore currents along the coast. With astronomical pull increasing this weekend into early next week and persistent long period easterly swell, expect rip currents especially to strengthen.

Increased southeasterly winds due to the strengthening pressure gradient along the lower Texas coast will drive periodic Small Craft Caution to Small Craft Advisory conditions, mainly along the bay, and gradually build Gulf seas towards 4 to 6 feet each afternoon into early next week. Have issued a brief SCA from this afternoon into late this evening across the bay and northern nearshore Gulf waters. There is a low chance of streamer showers or isolated thunderstorms, especially by mid to late next week.
