Summer heat and Saharan dust

  

  • Heat index 105° to 110°
  • Hazy sky from Saharan dust this weekend
  • Monitoring tropical development for potential impacts to US Coast in early- to mid-July

FOERCAST DETAILS:

Temperatures will continue to run a little above average with highs between 95° and 100°, but when you factor in the humidity, it’ll feel like 105°-110° for a few hours each afterno on.

Tropical moisture will enter the Southern Gulf of Mexico this weekend, and some of it should hit the Rio Grande Valley, but there’s also a small chance isolated light showers could develop south of Highway 90 on Sunday.

Most of us will just notice extra clouds in the sky on Sunday.

SAHARAN DUST:

Skies will be hazy from Saharan dust over the weekend (Copyright 2024 by KSAT – All rights reserved.)

African dust (Saharan Air Layer) is expected to stream over San Antonio by late Friday/early Saturday, but the amount will be light at first.

More noticeable concentrations of dust will add a haze to the sky on Sunday, which will also cause more vibrant sunrises and sunsets.

TROPICS:

Areas of potential tropical development. (Copyright 2024 by KSAT – All rights reserved.)

Two areas of potential development in the tropics over the next seven days. The first is in the Caribbean and is likely to stay unorganized with most of it’s moisture moving into Mexico.

The second area is in the open Atlantic and is likely to turn into a tropical cyclone as it heads west. *If* it happens to impact the U.S. or Mexico, it’d be well after the Fourth of July.
