DISCUSSION

Issued at 1003 PM CDT Fri Apr 24 2026

Deep South Texas and the Rio Grande Valley will remain on the northern periphery of 500 mb high pressure, which will remain centered, more of less, south of the region over Mexico. Dry weather will result, although some model guidance suggests that convection initiating over the neighboring higher terrain of northern Mexico may become an occasional threat, especially west of the Interstate 69C corridor. Additionally, with the presence of the mid-level high, well above normal daytime highs and overnight lows are also forecast.

Beach-wise, generally moderate seas may result in an elevated risk of rip currents at the beaches along the Lower Texas Coast through the next several days.

AVIATION

(12Z TAFS) Issued at 555 AM CDT Sat Apr 25 2026

MVFR and pesky IFR conditions with patchy fog near daybreak give way to VFR conditions by mid-morning. A southeast breeze is expected this afternoon into this evening, before MVFR ceilings gradually return.

MARINE

Issued at 1003 PM CDT Fri Apr 24 2026

Moderate to breezy winds and generally moderate seas will prevail along the Lower Texas Coast through the forecast with surface high pressure in place. Although Small Craft Advisory is not expected to be needed, Small Craft Should Exercise Caution is likely to be needed occasionally due to winds and/or seas.
