Thursday's warm front will bring clouds and a few showers, and isentropic lift will help set off some heavier rain in a few spots. Isentropic left is common with fronts over Florida lifting north, forcing warm air aloft. The air cools, water condenses out, and it rains. Sometimes a lot of rain. A similar event in boynton a few weeks ago left flooding in just a few hours. I'm not expecting flooding rain Thursday, but heavier cells are possible in the evening.
