400 PM EDT Wed Sep 3 2025

.SYNOPSIS...A frontal boundary extending from the Florida Keys to
the north-central Gulf near 26N90W will continue to weaken, becoming
a frontal trough by tonight, and likely persisting over the east-
central Gulf through Fri. This system will continue to generate
scattered to numerous showers and isolated thunderstorms, mainly
across the eastern part of the basin. Elsewhere, a weak pressure
gradient in place will maintain gentle to moderate winds with
slight to locally moderate seas through the forecast period.
