well NE of the area Tue and Tue night while continuing to
strengthen. Another high pressure area will build E into the
northern waters Sun into Sun night, then move E of the area Mon.
Yet another high will build E towards the region Tue and Tue
night. The high will weaken over the N and central portions Wed,
