Synopsis: High pressure near Bermuda continues to ridge over northern Florida. This will keep a southeast wind flow around 10 knots over the gulf coast waters for the next couple of days. Partly cloudy skies can be expected early in the day with scattered showers and storms this afternoon and again on Monday afternoon. The ridge shifts south by Tuesday as a trough moves over the eastern U.S. This will cause a shift in the winds to the southwest remaining 10 knots or less. With this pattern, the highest chances of showers and storms will be in the early morning hours, then pushing east over land by the afternoon allowing for some clearing late afternoon through the evening hours. Gusty winds, choppy seas and dangerous lightning can be expected in the vicinity of these storms.
