Gentle to light winds are noted over the northern Gulf, and moderate easterly winds are observed over the southern Gulf, south of the ridge axis. A few showers are likely ongoing over the south central Gulf, ahead of an upper trough moving eastward across the Southern Plains and northern Mexico. The ridging will persist from the western Atlantic across the northern Gulf through Sun night. Moderate E to SE flow will set up over most areas, with 2 to 4 ft seas. The upper trough will stall across the far northwest Gulf and amplify, allowing increased deep layer moisture and possible a few showers over the eastern Gulf through late week. A weak trough will form over the Yucatan Peninsula during the evenings, move offshore the Peninsula to over the eastern Bay of Campeche in the mornings, then dissipate in the afternoons. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Thunderstorms are generating along a trough reaching from central Cuba to 11N78W, just north of eastern Panama. The trough will drift slowly west through Thu then will dissipate. Moderate to fresh trades will persist east of the trough, with pulses of fresh to strong trade winds off northeast Colombia mainly at night. ...SW N ATLANTIC INCLUDING THE BAHAMAS... A stationary front extends from 31N74W to near Abaco Island in the northern Bahamas will dissipate later today.
