After a record-setting Memorial Day weekend (heat index values soared above 110°), some relief is in the forecast.

Storms are expected to gather to our northwest and move in the direction of South Texas this evening and tonight. While it’s not a “slam dunk” forecast, the odds of seeing rain are better than we’ve seen in a while.

  • Tuesday will still bring hot and humid weather, with heat index values of 102-105°
  • By Tuesday evening, storms will be fairly widespread to our north and northwest
  • As the storms come together and move south/southeast, rain chances begin to increase in San Antonio after dinnertime
  • Clusters of storms may arrive with severe weather, with the biggest threat being strong, gusty winds
  • Pockets of heavy rainfall will also be possible

Our rain chances will be dependent on what takes shape to our west and northwest. Storms are forecast to develop across West Texas and cluster together, while pushing east and southeast. With this kind of weather, the main severe threat is often gusty winds. Pockets of heavy rain will also develop. Isolated hail, with the stronger storms, could be an issue, too. With all that being said, not everyone will get rainfall.

Air quality has been an issue of late, with San Antonio seeing “unhealthy air for those who are sensitive,” meaning asthma sufferers and those with respiratory issues may be affected. Smoke from Central America and Mexico has been the largest contributor to the hazy conditions. Thankfully, should we see rainfall, air quality would also improve.
