The front will then lift N as a warm front Sat afternoon through Sun, in advance of Gulf of Mexico low pressure that will move NE across Florida Sat night. This low will move through the NW Atlantic waters Sun through Sun night, when a large area of southerly gales is expected E of the low. Widespread showers and thunderstorms are expected over most of the western half of the area through the weekend.
