.DISCUSSION...
A broad surface high pressure system will remain parked over the
coastal waters through next Tuesday. This will keep winds light and
variable at 10 knots or less and seas calm at 2 feet or less through
the weekend and into early next week. A few storms may pop up each
day with locally gusty winds, but overall rain chances will remain
low through Tuesday. The high is expected to shift to the east on
Wednesday, and a more persistent southeast wind of 10 knots will
develop on the western periphery of the high. Thunderstorm chances
will also increase with more numerous showers and thunderstorms
forming over the waters.
