Short Term - Now through Saturday
An elongated mid level ridge will continue to edge further westward across the central CONUS into this weekend, as surface high pressure builds overhead. Subsidence will help to suppress any mentionable rain chances into the weekend, along with the intrusion of drier air at mid to upper levels. With the pressure/thermal gradient relaxing into the weekend, winds will remain light to moderate through the short term. Temperatures will continue to rise under the influence of the ridge with triple digits expected across much of Deep South Texas and the Rio Grande Valley by Saturday. Elevated boundary level moisture will lead to mild and muggy nigheights and as drier air mixes down during the day, each afternoon will be hot, but slightly less humid than the past few days.
Long Term - Saturday Night through Thursday
The long term continues with a 500 mb ridge centered over northern Mexico extending into the Desert Southwest, while mid to upper level troughing over the northern Gulf of Mexico into the southeastern US. Early next week, the mid-level weakness moves northward over the southern Appalachians as a strengthening 500 mb ridge retrogrades to the west across the Gulf of Mexico by midweek. This weather pattern will continue to produce hot and humid conditions with temperatures well above normal. Rain-free conditions are expected across deep south Texas through the period. Surface high pressure across the Gulf of Mexico will result in a fairly weak pressure gradient through the rest of the holiday weekend. Breezy southeast winds are expected to return for the upcoming week as the pressure gradient strengthens. Dewpoints may increase a few degrees next week with afternoon temperatures reaching near heat advisory levels across portions of the region.
.MARINE (Now through Saturday): Favorable marine conditions are expected through the short term. As surface high pressure continues to move overhead, moderate to light southeasterly winds will persist into the weekend and seas will decrease and remain low.
Saturday Night through Thursday: The pressure gradient will remain fairly weak through the rest of the holiday weekend with high pressure in control. This will maintain light to moderate winds and low to moderate seas through the weekend. The pressure gradient is expected to strengthen early next week and may support exercise caution conditions along the lower Texas coast by Monday.
