CORPUS CHRISTI, Texas — An abundance of heat and humidity prevails over the Coastal Bend early this week, resulting in heat indices of between 105 and 109 degrees each afternoon.
An upper-level disturbance is expected to develop by midweek, though, and significant rain is likely by late week.
The combination of afternoon heat-index values in the danger zone, and overnight conditions still quite warm and humid, mean special attention should be paid to people at-risk, and to pets who spend their time outdoors.
By late Wednesday, showers and thunderstorms move into the region as an upper-level disturbance deepens over the area.
Storms will become numerous-to-widespread Thursday and Friday, resulting in localized, heavy rainfall and flash flooding.
The system lifts northeast, away from South Texas, by the weekend and will leave partly-cloudy skies and warming temperatures.
Highs will be in the 90s, except middle-to-upper 80s on Thursday and Friday.
Lows will linger in the middle-to-upper 70s.
