San Antonio locals can expect a mixed bag of hot temperatures and occasional rain for the first week of August.

The heat index, a measure of how hot it feels when humidity is factored in, could climb as high as 106, according to the National Weather Service.

The evening brings a slight reprieve, with partly cloudy skies and a low around 78 degrees. A chance of thunderstorms lingers, mainly before 7pm. The weekend won't offer much of a break from the heat, with a "40 percent chance of showers and thunderstorms after 1pm" on Saturday and similar conditions on Sunday, Monday, and Tuesday, as stated by the National Weather Service.

Heading into Wednesday, residents can look forward to a high of 98 degrees under sunny skies, followed by a mostly clear night with a low around 77. The same pattern is expected to hold through Thursday, as per the National Weather Service.

While the fluctuating chances of rain might offer some respite, the consistently high temperatures are likely to affect day-to-day activities.

According to the National Weather Service forecast, the repeated "mostly sunny and hot" days are accompanied by light winds, providing minimal relief from the heat.
