Looking at above satellite + radar you can see the stream of moisture moving north across Florida while showers and storms in Mississippi Valley more east. This will all continue over The East Tuesday into Wednesday. By late week - a tropical system will move into The Gulf. At the same time a front in Rockies approach the East Coast....not a winning combination for Memorial Day Weekend if you are in the East. Below - today's risk of severe weather - dark green and yellow.
Below - animated maps for the next 2 days....followed by rainfall predictions for the next 5 days. Rainfall only goes out through Friday...so by the holiday weekend - it will expand north to cover New England.
Be safe.
