FORECAST
South Central Texas faces another scorching day Tuesday with highs near 100°F. The hot, dry pattern is expected to continue through the end of the week as a strong high-pressure ridge remains over Texas. A Heat Advisory is in effect from noon to 7 p.m. with heat indices reaching 108–110°F.
The heat isn’t going anywhere though. Temperatures continue to rise near 100°F and heat indices topping 110°F.
RAIN CHANCES
Rain remains unlikely through the rest of the workweek as the high-pressure ridge keeps skies mostly sunny and conditions dry. By the weekend, the ridge is expected to shift west, allowing a weak front to approach South Central Texas.

That front could bring only a 10 to 20 percent chance of isolated showers and thunderstorms Saturday. While a few locations may see brief rainfall, widespread precipitation is not expected, and it’ll mainly be hot and humid.
