DISCUSSION

Issued at 1021 PM CDT Tue Apr 7 2026

Low-level moisture is set to increase over the coming days as we have the return of southeasterly winds. Most of the moisture will be confined to the coastal areas and Gulf waters to start. As a result, may see some showers pop up along those areas (15-20% chance) Wednesday afternoon/night. Otherwise, expect skies to be partly cloudy to sunny with highs in the upper 80s.

Thursday is projected to be a little more active as moisture across the area continues to increase and a weak coastal trough develops along the TX coast. Coverage of showers and storms will start off isolated to scattered Thursday morning as activity moves in from the Gulf. By Thursday afternoon, daytime heating will contribute to destabilization and activity will push further inland. Highest PoPs lie along and south of the I-10 corridor.

Rain chances are expected to continue Thursday night into Friday. Coverage is expected to increase Friday in response to a weak mid-upper level trough that will traverse the state. Scattered to numerous showers and thunderstorms are expected for areas along and south of I-10 during the morning hours Friday. As the day progresses, and daytime heating plays its role, expect more showers and storms to develop further inland. With the amount of available moisture, some of these showers and storms could produce locally heavy rainfall. While no significant flooding is anticipated, water could pond on roadways and low-lying areas. Highs for Friday are expected to be in the upper 70s for the majority of the area.

Activity will taper off overnight Friday into Saturday morning. Any showers will likely be confined to the coast. Saturday will feature an upper-level ridge building into the area, which should limit rain chances. However, a weak disturbance may interact with lingering moisture and result in isolated to scattered showers and thunderstorms along and south of I-10 and west of I-45.

As for Sunday into early next week, still going to see those rain chances to continue, with the highest chances over the Brazos Valley/Piney Woods during the afternoon hours with peak heating.

MARINE

Issued at 1021 PM CDT Tue Apr 7 2026

Light to moderate southeast winds will continue through early next week. Winds are expected to be the strongest during the early night to mid- morning hours. Caution Flags may be required at times. Strong rip currents are also possible along the Gulf facing beaches. Seas will be 3 to 5 feet through Thursday, however, a swell driven by stronger winds over the eastern and northern Gulf waters is expected to move into our local area and increase seas to 4-7 feet late Thursday into early next week. Seas could be slightly higher over the offshore Gulf waters. Caution flags and/or Small Craft Advisories may be needed. There is a daily chance for showers and thunderstorms through the weekend, highest on Thursday night into Friday. Elevated winds and seas may occur in and around strong thunderstorms.
