Houston weather forecast: More heavy rain possible early Thursday, Storm Alert issued

The National Weather Service has placed Washington, Grimes, Walker and Trinity Counties under a flood watch through Thursday evening. Other counties may be added based on how rain develops, but the bottom line is that conditions are favorable for heavy rain through at least the next 24-36 hours. 2-5" totals could easily occur in spots, so stay weather aware until our pattern settles down a bit. The next big round of widespread rain likely moving in Thursday morning.
