High Heat Index in San Antonio, but Some Good News in Forecast

KEY POINTS:

• 
  National Weather Service has issued a Heat Advisory from noon to 8 p.m. for a peak heat index ranging from 105° to 110°

• 
  Less humid, but hotter through Tuesday. Highs as hot at 103° to 105° possible by Tuesday

• 
  Slight weather pattern change allows for a dip below 100° by the end of the week/weekend, with a small rain chance

FORECAST DETAILS:

The heat high is *just* to our west, but because humidity is high, it’ll still be pretty hot this Sunday. In fact, peak heat index values will range from 105° to 110° across South Central Texas.

While humidity will come down slightly in the days ahead, the heat high moves directly over Texas. This means temperatures will climb even more, especially through Tuesday. Highs Tuesday could potentially be the hottest of the year so far. Up to date, the hottest temperature recorded at San Antonio International this year was 103° on June 4.

Thankfully, the heat high doesn’t stay directly over us. In fact, a low pressure system will move across Deep South Texas late this week, allowing for a dip in temperatures below 100° and even a small chance for rain. We will keep you posted! ~ Sarah
