Excessive rainfall is likely on Wednesday along the East Coast.

There is a chance for excessive rainfall across the outlook region today as widespread showers and thunderstorms move across the eastern US along and ahead of a cold front. A large line of moderate to heavy rain will spread across the region early Wednesday morning and persist throughout the day into the late evening hours due to the slow progression of the front. A swatch of 1-2 inch rainfall totals, with locally higher amounts possible in stronger rain bands. Extreme rainfall rates will be possible along the Florida Panhandle where ample moisture and convective bands are forecast to set up. Here, there will be 3-5 inches of rain possible. Given the recent heavy snows in the Northeast, some of which has melted, this heavy rainfall may lead to periods of flash flooding in some flood prone areas in that region.
