.DISCUSSION...
A very early Summer like weather set up will keep a persistent south-
southeast flow of 10 to 15 knots in place through the middle of next
week. Seas will remain well below any hazardous limits at 1 to 3
feet through the period. The main concern will be a series of
thunderstorm complexes that are expected to slide down from the
northwest and move into the waters starting Saturday and then
potentially lasting through the middle of next week. If a
thunderstorm complex does move into the waters, a period of stronger
winds, heavy rainfall, and lightning will accompany the storms.
