form within the ridge Mon and shift to the southern waters as

developing low pressure passes to the W and NW of the area Mon

northern waters Tue and over the central areas Tue night. Another

cold front will approach the area from the W Tue night, then move

across the N and central waters Wed and Wed night and dissipate.
