SAN ANTONIO — Memorial Day weekend is a seasonal rite of passage: Tubers hit Hill Country rivers, barbecue pits come rolling out and young Texans cherish their freedom for another summer.
And, in South Texas, millions are expected to see their first 100-degree days of the year as a heat wave bakes the region. Temperatures in San Antonio are steadily rising as we near the weekend, with the Alamo City expected to see triple-digit heat on Saturday—a day when the mercury historically tops out at 93 degrees on average.
On average, the first 100-degree day doesn't arrive in San Antonio until June 28.
The National Weather Service says record heat is expected in South communities, with some border communities enduring extreme heat. While in San Antonio the high temperature will waver between 97 and 102 Friday through Sunday, heat indices indicate it will feel like it's between 105 and 110.
In fact, high humidity levels this week mean it it's already feeling like it's upwards of 100 degrees as early as Tuesday. Strong heat this weekend could also result in heat advisories being issued by NWS.
Aside from an isolated, 10% chance of storms this week, no major precipitation will provide relief, either. A cap of warm air will limit storm activity Wednesday through Sunday. Follow the latest updates from KENS 5 Weather here.
Here's what to expect day by day:
Friday: Low of 76, high of 99, with "feels-like" temperatures between 105 and 110 degrees.
Saturday: Low of 76, high of 100, with "feels-like" temperatures between 105 and 110 degrees.
Sunday: Low of 77, high of 101, with "feels-like" temperatures between 105 and 110 degrees.
Memorial Day: Low of 72, high of 100, with "feels-like" temperatures between 105 and 110 degrees.
How to stay safe
When it's this hot outside, it's important to take precautions to stay cool, hydrated and safe.
If outside for an extended period of time this holiday weekend, remember to hydrate consistently, if you aren't feeling thirsty. Don't leave pets or young ones in cars, which can heat up quickly to dangerous levels.
Also, remember to wear loose-fitting, light-colored clothes, and relax in shade whenever you can. Stock up on sunscreen and make sure to use it before heading outside.
