CORPUS CHRISTI, Texas — We're starting the week with high humidity and above-average temperatures which will give us sweltering heat with afternoon heat indices of 105-110.
Rain chances will be low to start the week but will increase from Wednesday through Friday as low pressure aloft develops over south Texas. We are also watching a plume of Saharan dust which is moving across the Atlantic and is forecast to arrive in south Texas from Wednesday into the weekend. This will lead to hazy skies and colorful sunrise and sunsets.
Today and Tuesday look partly cloudy, hot and humid, reaching the low 90s in Corpus Christi to the upper 90s inland with south-southeast winds at 15-25 mph. There is an isolated shower or thunderstorm chance. Heat indices (feels like temperatures) will reach 105-110 degrees.
Scattered showers and thunderstorms are expected Wednesday through Friday, some of which could produce locally heavy rain. It won't be as hot with high temperatures reaching the upper 80s in Corpus Christi to low 90s inland and southeast winds at 10-20 mph. Humidity will be high producing heat indices of 98-104.
Rain chances decrease for the weekend to only isolated storms and high temperatures near 90. Saharan dust is projected to be over the Coastal Bend which will give us hazy skies.
