Marine Weather and Tide Forecast for Diamondhead, MS

LONG TERM
(Thursday night through Tuesday)
Issued at 414 AM CST Wed Jan 15 2025

A southern stream shortwave will approach the area ahead of a stronger system on Friday. As low pressure develops across Oklahoma and Arkansas by late Friday and pushes east, it will drag a cold front through the area. While there may be some elevated instability Friday night and early Saturday morning as southerly flow from the Gulf increase thunder cannot be ruled out and is mentioned in the forecast. That said, no severe weather is expected with this system at this time.

Now for the difficult part of the forecast as we move into the latter part of the weekend and the beginning of next week. The one thing that looks certain at this point is the much colder air that will be ushered into the area and persist through a good portion of next week. Temperatures on Sunday will struggle to make it out of the 40s and by Monday high temperatures across most of the area will be in upper 30s and lower 40s. Morning lows will begin to be an issue on Monday morning as mid to upper 20s are expected across a large part of the area. Tuesday morning will bring some of the coldest temperatures of the year with temperatures in the teens not impossible, especially over the northern third of the forecast area. For now, kept most areas at least in the lower 20s but regardless, advisories for the cold temperatures at the very least will be needed.

In addition to the frigid temperatures, concerns ramp up by Tuesday morning for the possibility of wintry precipitation.
Models continue to be all over the place on the placement of the features driving the chances and the timing in which those features move into or near the area. Opted to keep the wintry weather mentions in the forecast for the northern parts of the area but there is still considerable uncertainty on type and accumulation, if there is any. South of the tidal lakes, kept all precipitation as liquid for now. Of course, any precipitation that does fall as liquid and lingers would freeze Tuesday night.
There continues to be a large amount of uncertainty on the eventual evolution of this event and while confidence is quite low on the impacts, probabilities continue to suggest some wintry precipitation will be seen in the area. That could easily change in either direction with subsequent forecasts.

Generally VFR conditions are forecast for the forecast period.
Ceilings will lower as the day goes on but should still remain VFR. Rain chances increase this afternoon enough to include some PROB 30 at most of the terminals but overall rain amounts are expected to be on the light side. By the end of the forecast period (late tonight and early tomorrow morning), increasing clouds will likely bring MVFR or even IFR conditions at some of the terminals.
