Long Term
(Saturday Night through Thursday) Issued at 327am CDT Fri Jun 14 2024

This portion of the total forecast is highly dependent on the future development and movement of a tropical system that may develop in the Bay of Campeche around Tuesday. At a minimum, deep tropical moisture, featuring precipitable water values between 2 and nearly 3 inches, will flux into the BRO CWFA from the Bay of Campeche and the western Gulf of Mexico. This will result in a steadily-increasing chance of showers and thunderstorms, with initially isolated to scattered convection over the eastern portion of Deep South Texas and the Rio Grande Valley gradually transitioning to scattered to numerous activity across the whole of the area by the end of the long term period. With the exception of the northern halves of Brooks County, Jim Hogg County, and Zapata County, where no drought exists, the latest drought map indicates Abnormally Dry to Moderate Drought conditions over the remainder of the inland portion of the BRO CWFA. Aforementioned substantial rains, if they materialize, will have the possibility of ending any and all drought within the region by the time of their conclusion.

Temperature-wise, above normal daytime highs, not surprisingly, will be cooled to below normal levels courtesy of increased cloud cover and the significant chances for showers and thunderstorms. Although heat indices may result in a SPECIAL WEATHER STATEMENT Sunday through Tuesday, a HEAT ADVISORY is not forecast for any of those days, with heat indices continuing to decline on Wednesday and Thursday.

Additionally, with elevated seas anticipated along the Lower Texas Coast (please see the

Marine
ction below), an elevated risk of rip currents (MODERATE or HIGH), COASTAL FLOOD products (ADVISORY or WARNING), and HIGH SURF products (ADVISORY or WARNING) are likely to be needed at the local beaches, possibly commencing on Monday or Tuesday.

Finally, some model guidance suggests that a more organized tropical system will move across the Yucatan Peninsula around June 21st and approach the mouth of the Rio Grande River around June 23rd. Given the amount of time yet to pass, nothing definite is laid in stone, so will simply have to monitor this concern as the second week of June becomes the third.

Marine
(Today through Saturday) Issued at 327am CDT Fri Jun 14 2024

Favorable conditions are expected to persist through Saturday, as a weak pressure gradient allows for light to moderate winds and low to moderate seas. Some isolated showers and thunderstorms are possible through Saturday, and locally elevated seas and winds are possible with these showers and thunderstorms.

(Saturday Night through Thursday) This portion of the marine forecast is highly dependent on the future development and movement of a tropical system that may develop in the Bay of Campeche around Tuesday. If model guidance is to believed, Small Craft Advisory conditions, at a minimum, are possible along the Lower Texas Coast beginning Monday night, especially for the Gulf of Mexico waters from 0 to 60 nautical miles offshore. Mariners are advised to monitor the Coastal Waters Forecast through the next several days.
