CORPUS CHRISTI, TX — The large, dominant upper level ridge that brought days of extreme heat and humidity now has shifted well north of the region, placing South Texas in tropical easterly flow. That regime means more clouds, lower afternoon temperatures, and sea breeze showers through the week. The northward shift of the upper level ridge allows the combination of daytime heating and sea breeze activity to bring isolated to scattered showers and thunderstorms. Moreover, as is characteristic of tropical easterly flow, minor mid-level disturbances will periodically enhance rain chances. We will be watching a stronger disturbance possibly develop in the Gulf of Mexico mid-week and move westward by next Friday to increase Coastal Bend rain chances. Meanwhile, expect highs in the lower 90s and lows in the middle to upper 70s.
