Marine Weather and Tide Forecast for Grenada, MS

DISCUSSION
Issued at 328 AM CST Mon Dec 8 2025

Through tonight: Colder than normal temperatures and dry weather is expected. Early morning satellite imagery/RAP analysis showed an upper level trough axis nearly along the Mississippi/Alabama state line. This upper level trough was supporting a cold front that latest surface analysis showed has pushed southeast of our CWA Local radars showed most of the measurable rainfall has shifted east of Mississippi although a thick layer of stratus remained over our CWA
As the upper level trough continues to shift east today and surface ridging from the west moves over over our CWA, clouds will gradually decrease. In the wake of the cold front, cooler and drier air will continue to filter into our CWA High temperatures will be held in the 40s over the north and in the 50s central and south. Tonight the wind will decouple and become near calm. There will likely remain some high clouds hindering prime radiational cooling but morning lows will bottom out below freezing at most locations. /22/

Tuesday through next Sunday: Temperatures will moderate to near or slightly above seasonal averages for Wednesday and Thursday.
By late week, another cold front is expected to approach the region, bringing the potential for the return of rain chances.
While model trends have reduced the signal for precip, we will still maintain low-end rain chances across the southeast. In the wake of this front, temperatures may again plummet into the mid-20s, with highs struggling to reach 50 heading into next weekend. While this colder scenario is possible, model consensus remains limited at this range regarding whether another surge of polar air will reach our CWA /KP/
