Happy Sunday!

It’s going to be a humid and warm day in San Antonio with only a 10% chance for morning mist and a stray shower. A weak cool front will be moving through Texas today, but unfortunately, it’ll fade before making it to the Alamo City.

So, expect warm afternoons this week -- although not as hot as last week -- with highs near 90°.

Meanwhile, a tropical system will likely move into the Gulf of Mexico this week. Once it reaches tropical storm strength, it’ll be given the name Helene.

Helene will likely make landfall anywhere from Mississippi to Florida. While not good news for our neighbors to the east, the system will pull drier air into Texas. This means that humidity will be pleasantly low for South Central Texas Friday through the weekend. Expect cooler mornings in the 60s and pleasantly warm, but comfortable afternoons.

With a lot to watch this week, we’ll be keeping you posted! ~ Sarah
