FORECAST HIGHLIGHTS
FORECAST
South Central Texas is bracing for another scorching day on Tuesday, with temperatures expected to soar near 100°F. This persistent hot and dry weather pattern is anticipated to linger through the end of the week, as a robust high-pressure ridge continues to dominate the region. A Heat Advisory is currently in effect from noon to 7 p.m., warning residents of heat indices that may spike to between 108°F and 110°F.
Unfortunately, this oppressive heat is unlikely to relent anytime soon. As temperatures hover near the 100°F mark, the heat indices are expected to remain elevated, exceeding 110°F in many areas.
RAIN CHANCES
Rainfall appears unlikely for the remainder of the workweek, as the high-pressure ridge keeps skies predominantly clear and conditions dry. However, by the weekend, a shift in the ridge is expected to allow a weak front to approach South Central Texas.
Rain will only be very spotty over the weekend as the heat high moves west.
