CORPUS CHRISTI, TX —A massive upper level ridge is expected to remain in place over the southern and southwestern U.S. this weekend and through most of next week, maintaining the threat of extreme heat and trapped humidity with little to no precipitation. Some relief is possible by the end of next week. Previous medium and longer range atmospheric models depicted the ridge to shift into the Middle Mississippi Valley later next week, giving the Texas coast deep layer tropical moisture along with less heat and some rain chances. Later model runs maintain the upper ridge across the Southern Plains, with only a few end-of-week showers expected. Highs will remain in the middle to upper 90s, with lows in the middle 70s to around 80. A heat advisory in effect today is likely to be re-issued for Sunday and again on Monday.
