Marine Weather and Tide Forecast for Pass Christian, MS

LONG TERM
(Monday through Friday night)
Issued at 258 PM CDT Sat Apr 19 2025

Forecast patterns changes a little and we will see better rain chances over the course of the work week with the first legit chance for some rain on Monday. The front although weak will continue to drift southeast towards the region Monday. This will allow for better LL convergence and combine that with the mid lvl ridge weakening and shifting southeast, hghts falling and cooling, abundant moisture in place and we should see scattered showers and a few thunderstorms. Not anticipating much in the way of strong to severe storms with the lack of any real forcing. The boundary will pivot more west to east heading into Monday across the region and this will allow for a few more showers and a storm or two but again nothing of any serious impact.

Things may begin to change heading into the back half of the work week. The gulf will remain open so we will continue to build moisture and as we heat up each day we will destabilize with storms possible but the biggest difference was mentioned by the midnight shift and that is the models now not drifting the front as far north and now a series of disturbances working across Mexico/TX and through the Lower MS Valley. The first could be Wednesday or Wednesday night with the next about 36-48 hours later and possibly a 3rd at the end of the weekend. Each of these could produce an MCS just off to our west/west-southwest and drive them across the CWA with a few strong to severe storms possible.
We will need to keep a closer eye on these as small adjustments will make big differences in the forecast and could mean the difference from warm humid days with scattered clouds and maybe a shower or two or a more active complex of storms. /CAB/

MARINE
Issued at 258 PM CDT Sat Apr 19 2025

Winds have been a little breezy today but look like they will increase a little more overnight as a surface low gets going in the southern Plains. Wind speeds will likely approach 20kt today and tonight and slowly ease through Sun. An SCY is already in place for the waters west of the mouth of the river and may need to be expanded east tonight. Winds will back down some tomorrow but more so Sunday night as the weak front drifts closer towards the region. However, onshore flow will continue well into next week. /CAB/
