Most of the rain is forecast to fall in as little as 3-6 hours. A small chance of heavier rain and flooding could pose "an elevated threat to life and cause significant disruptions to transportation, flood underground infrastructure and basements and first floors of residences and businesses," with water rescues needed, the weather service said.

Friday will bring a decent chance for scattered afternoon/ evening storms, then we have a tricky weekend forecast. A cold front will approach, then stall and it's a challenge as to how close to Houston the front will stall.
