It’s safe to say summer is in full swing in San Antonio. Here’s what you need to know about this week’s weather:

Feelin’ Hot😎

  • As a ridge of high pressure settles over Texas this week, temperatures will rise
  • Each afternoon, the thermometer will reach the upper-90s, if not 100 degrees
  • Unfortunately, the high pressure system will also keep things dry -- there will be no significant chance for rain

Lookin’ Hazy🌆

  • If you were out and about this past weekend, you definitely noticed the presence of Saharan dust -- especially Saturday
  • Although the dust layer will be thin at the beginning of this week, a second, more noticeable plume is expected to arrive Thursday, July 2 and eventually clear out during the July 4th weekend
  • The fine dust can cause allergy-like symptoms and unhealthy air quality for those with respiratory issues
  • Colorful sunrises and sunsets will be possible Thursday through the weekend
  • While Saharan dust’s arrival in Texas is an annual event, it has gotten a lot of additional attention this year amid the COVID-19 pandemic. That’s led some KSAT viewers to send questions about the dust to the Weather Authority team
