High pressure keeps hot, mostly dry conditions into next week

FORECAST HIGHLIGHTS

WEEKEND: Very hot conditions continue today, with highs generally in the upper 90s to near 103°.

NEXT WEEK: Unfortunately, the heat sticks around. Above-average temperatures will continue through much of next week, with only limited rain chances.

RAIN: Daily sea-breeze showers and thunderstorms are possible

PATTERN CHANGE: We can’t solidify a change, but we are watching the chance next week could finally bring some relief from the heat

FORECAST

TODAY

South Texas remains under a Heat Advisory today from noon to 7 p.m., with heat index values climbing to 108°. Expect highs near 100° and a slim chance of isolated afternoon storms near the Coastal Plains and San Antonio.

NEXT WEEK

Unfortunately, cooler weather isn’t showing up anytime soon. Very little change is expected Monday as High pressure will continue to dominate the region, maintaining a pattern of hot, mostly dry weather. High temperatures should stay in the mid-90s to just above 100° each afternoon.

The Coastal Plains will have the best chance for rain, with daily sea-breeze showers and thunderstorms possible during the afternoon and evening. While most inland areas remain dry, isolated storms may develop near the coast as the day progresses.

A POTENTIAL PATTERN CHANGE?

There may finally be some hope toward the end of NEXT WEEKEND. Forecast models are hinting at a possible pattern shift that could bring temperatures back below 100° and increase rain chances across the region. However, there is still disagreement. For now, the heat remains the dominant story, but this is something we’ll be watching closely as we get closer.
