| Area Forecast Discussion ...UPDATED National Weather Service Brownsville TX 642pm CDT Wednesday May 8 2024 Long Term (Friday through next Wednesday) Issued at 236pm CDT Wednesday May 8 2024 A cold front is expected to approach Deep South Texas and the Rio Grande Valley Friday morning. Once the front pushes through, temperatures are expected to be more seasonable in the upper 80s and lower 90s for the region. While the surface winds will shift behind the front towards the northeast, they will quickly shift back towards the east by Saturday and then southeast by Sunday. This will allow for temperatures to heat up again as the frontal boundary retreats backwards as a warm front. As such, temperatures will be back to being above normal with highs mostly in the mid to upper 90s and some places in the triple digits by Monday and lasting through the rest of the long term forecast period. Meanwhile, the overnight low temperatures are expected to be in the 70s. Plenty of low-level moisture along with a bit of forcing and instability could support the development of showers and thunderstorms during the passage of the cold front on Friday. A bit of a weak overrunning will support isolated to scattered showers and thunderstorms over the weekend. The return of the onshore flow on Sunday could also help a bit with the development of showers and thunderstorms on Sunday and Monday. Marine Issued at 236pm CDT Wednesday May 8 2024 Tonight through Thursday Night...Moderate southeast winds and moderate seas will prevail through the forecast period. Tonight, we could see some patchy fog/hazy conditions on the Gulf waters. Brief periods of Small Craft Exercise Caution conditions will be possible in the afternoon, especially across the Laguna Madre due to elevated winds. Friday through Next Wednesday...Stronger northeasterly winds are expected to prevail in the wake of the cold front that will move over the Lower Texas Coast on Friday into Saturday. Small Craft Exercise Caution or Small Craft Advisories are possible for Friday afternoon. Winds are then expected to weaken on Saturday, with light to moderate winds and moderate seas prevailing along the Lower Texas Coast through the rest of the period.
