| Area Forecast Discussion ...UPDATED National Weather Service Brownsville TX 1137am CDT Fri April 26 2024 Long Term (Saturday night through Thursday) Issued at 344am CDT Fri April 26 2024 The tight pressure gradient continues to remain a factor in the long term forecast for Deep South Texas and the Rio Grande Valley at the start, but not expecting Wind Advisories to be needed as the current forecasted winds are in the range of 20-25 mph. As we move into the work week, an upper-level trough will into Northern Texas and move eastward, which will result in a zonal flow like pattern for a few days with a weak mid-level ridge sliding over the area by Wednesday. This mid-level ridge is not expected to stay over the area for long, as it will move eastward allowing for a zonal flow aloft to return to by the end of the work week. Meanwhile, at the surface, southerly to southeasterly flow is expected to continue, which will funnel more warm, humid air to the region. While the moisture advection does remain constant, the opportunities for rain appear do not look very promising. The greatest opportunity in the long term forecast period appears to be late Monday into Tuesday. A series of shortwaves will be moving through the upper levels that could help the development of convection along the Sierra Madre Mountains. Some of these showers and thunderstorms could make it to Deep South Texas and the Rio Grande Valley before they dissipate. However, rain chances remain in the range of 20 to 30 percent, as these types of showers and thunderstorms often do collapse once they move away from the mountains. Marine Issued at 344am CDT Fri April 26 2024 Today through Saturday: An already strong pressure gradient is expected to strengthen tonight as a series of low pressure areas extend from the South to the Central Plains.

Small Craft advisories already in place to are likely to be extended tonight and Saturday. saturday Night through Thursday...Hazardous conditions to start off on Saturday night due the elevated winds and seas from the tight pressure gradient.
