Key Messages
- Increasing cloudiness today. Rain chances begin trending upward tonight and Sunday, moreso west of Interstate 45. This rain will generally be light (and much needed).
- Clouds should begin clearing toward midweek as the slow moving upper level low pressure area tracks to our east. We may see some cooler weather filter in later next week.
- Increasing east and northeast winds and building seas this weekend across the marine areas.
