Synopsis for the Gulf of Mexico
349 PM EDT Sat May 18 2024

.SYNOPSIS...A weak stalled out front extends from southeastern
Louisiana to the extreme NE coast of Mexico. Numerous showers
and thunderstorms are north of 28N east of the front reaching
the NE Gulf. This activity is being aided by a mid-level trough.
The stalled front will begin to shift eastward tonight as a weak
cold front before stalling again on Sun and weaken gradually
through Mon. Elsewhere, moderate to fresh return flow will
dominate the basin through early Sun, pulsing to locally strong
near the Yucatan Peninsula and the Bay of Campeche. Winds will
slightly weaken Sun into early next week as the pressure gradient
relaxes. Meanwhile, areas of haze and smoke due to agricultural
fires in Mexico continue across most of the western Gulf and Bay
of Campeche. Moderate to locally fresh SE return flow will develop
again across the W Gulf Tue through Thu night.
