Marine Weather and Tide Forecast for Perdido Beach, AL

DISCUSSION
Issued at 300 PM CDT Thu Apr 30 2026

Zonal flow aloft will persist over our region through tonight south a large and broad upper trough extending from the northern Rockies to the New England coast. A mid/upper cut-off low pressure center over northern Baja-California will eject eastward and become absorbed into the northern trough on Friday. This will result in southwesterly flow aloft as the large trough evolves into a slightly positively-tilted medium amplified trough with the axis reaching the lower half of the Mississippi River by noon Saturday. Mid/upper level impulses will continue to traverse the region, with the strongest signal occurring Friday afternoon through the overnight hours due to residual energy from the decaying southern shortwave. Layer lifting and isentropic upglide will persist in the low levels as a frontal boundary just off the coast remains quasi-stationary through Friday evening. An inverted low-level trough across the western Gulf coastline and becomes quite elongated from the southwest Gulf to the Florida Panhandle while developing an internal low pressure area by Saturday morning. Scattered to occasional numerous showers along with a chance of thunderstorms will continue through Friday morning, followed by widespread showers and a chance of thunderstorms Friday afternoon and Friday night. The departures of the low level trough to our east will allow the rain to taper off Saturday morning and then reinforce the northerly wind flow as high pressure builds into the region from the northwest. Overall, we are expecting additional total rainfall amounts to range from 2 to 3 inches. A much drier airmass moves into the area behind the reinforced northerly flow with dry conditions expected through the first half of next week. A LOW risk of rip currents is expected through Monday night. /22
