.SYNOPSIS...High pressure extending westward from the Atlantic

across central Florida and over the Gulf will change little

weather pattern will support gentle to moderate east to

southeast winds south of 26N east of 94W, and light to gentle

southeast to south-southwest winds north of 26N into the

weekend. Light and variable winds are south of 26N west of 94W.

These winds will gentle to moderate east to southeast winds

occasional fresh to strong northeast to east winds offshore the

Yucatan peninsula at night. A mid-level trough combined with a 

very moist and unstable environment is generating scattered to

showers and thunderstorms are elsewhere south of about 28N. This 

activity is expected to persist into tonight as it lifts north.
