Long Term
(Tuesday Night through Sunday) Issued at 217am CDT Monday May 27 2024

The aforementioned 500 mb subtropical ridge will remain the dominant feature over the BRO CWFA through the period, with the center of this feature varying from the upper east coast of Mexico to just south of the Baja Peninsula. Although dry weather will prevail through a majority of the time for Deep South Texas and the Rio Grande Valley, isolated showers and thunderstorms are occasionally possible, and primarily over the northern ranchlands (Zapata, Jim Hogg, Brooks, and Kenedy counties). This will be due to convection initiating over neighboring Mexico courtesy of mid- level shortwaves and then migrating into ranchland area.

Additionally, well above normal daytime high and overnight low temperatures will also occur. Forecast heat indices for the long term forecast period suggest that a HEAT ADVISORY is most likely for inland portions of the BRO CWFA Friday and Saturday, with a SPECIAL WEATHER STATEMENT Wednesday, Thursday, and Sunday in lieu of the HEAT ADVISORY.
