Satellite imagery across the continental U.S. reveals much of the weather lies across the eastern half of the country.  A combination of a mid-latitude upper level low pressure system over the western Gulf of Mexico and deep layered, widespread tropical moisture will lead to rainfall across much of the Gulf Coast, Florida, and southeast U.S.  Across the Florida Peninsula, day time heating along  with the east and west coast sea breezes will trigger showers and thunderstorms by afternoon and evening.  Mid level steering flow has strengthened from the southwest thus all activity over the state will travel towards the northeast around 15-20 mph.
