Synopsis for the Gulf of Mexico
1039 PM EDT Fri Apr 30 2021

.SYNOPSIS...A weak frontal boundary will remain over the western
Gulf through Sat, then move northward as a warm front late Sat 
into Sun. Scattered showers and thunderstorms are expected near 
the front over the NW Gulf through early Sun. Areas of smoke and
haze are possible in the SW Gulf from agricultural fires in 
southern Mexico. Fresh southerly return flow will prevail early 
next week over much of the basin. Looking ahead, a weak cold
front could reach the Texas coast early Wed.
