High Pressure Brings Heat Back to Houston This Weekend

A building ridge will cut widespread rain and push daytime heat and humidity high enough to raise heat‑stress risks for outdoor workers and vulnerable residents.

Overview

  • Local forecasts said Friday that a ridge of high atmospheric pressure is moving over Southeast Texas and will suppress the rain‑producing pattern that soaked the region earlier this week.
  • Skies should dry and temperatures will climb into the mid‑to‑upper 90s this weekend with heat‑index values commonly above 100°F and near 105–108°F in some spots.
  • Rain chances are low and mostly isolated through the weekend so the widespread flooding threat that materialized earlier this week has largely ended.
  • The National Hurricane Center is monitoring two disturbances with modest odds of development over seven days — about 30% in the northeastern Gulf and about 10% near the Cabo Verde islands — and Saharan dust may limit eastern Atlantic formation.
  • The change matters for people and services: roads and yards will start to dry, outdoor workers and older adults face higher heat‑illness risk, and strengthening high pressure raises the odds Houston could reach its first 100°F day later next week.
