CORPUS CHRISTI, Texas — The powerful upper level ridge that has brought an oppressive combination of heat and humidity to the Coastal Bend all week long will reign supreme through the weekend, but its time is limited. Cooler air and isolated to scattered showers and storms return early next week. The heat and humidity continues to be dominant over the Coastal Bend through the weekend, with the upper level ridge heating the atmosphere and compressing the humidity to near the surface (where we live). That means no rain but heat indices of 105 to 115 during the afternoons.

By Monday, the upper ridge shifts into the Great Basin and allows a cold front to move southward through Texas. The front will only lower temperatures a couple of degrees, but it will combine with increasing Gulf moisture to bring isolated to scattered showers and thunderstorms. The best rain chance will be on Tuesday, but isolated showers and a few thunderstorms should persist through Thursday. Expect highs in the middle 90s, lowering to the lower 90s Tuesday through Thursday. Lows in the upper 70s will dip to the middle 70s Tuesday through Thursday.

TS Josephine in the tropical Atlantic will not threaten the U.S. but will make a close approach to the Lesser Antilles.
