Slim Rain Chances and Cool Weather to Follow – Weekly Forecast for South MS/AL/LA 12/15/24

We’re shifting to a warmer weather pattern for the next several days as the remnants of a stout high pressure system in Quebec slowly move towards the Atlantic. Since the southeast is on the back side of this high, it’s going to be quite warm for this time of year, but that’s not too unusual. Let’s take a look.

A stalled front in the central Plains will slowly gain traction after a weak surface low moves in from the southern Rockies. In the upper levels, this is a fairly weak shortwave trough that moves it into our neck of the woods on Tuesday and Wednesday. This will bring in a more linear cold front that will rain across much of the eastern US and dissipate by the time it reaches the coastal South.

What this means for us is that temperatures will be warm from Monday into Wednesday. Temperatures will be in the low 70s and reach the mid 70s by Wednesday with lows in the mid to upper 50s. Not only that, we’ll see some foggy mornings ahead with barely any wind and plenty of moisture at the surface. Tuesday will be a chance for some isolated rain showers mainly north of Hwy 84. By Wednesday, the main system I mentioned earlier will move in across much of Louisiana, central and northern Mississippi and parts of Alabama.

Taking a close look at Wednesday… it’s not looking like much. There’s a slim amount of precipitable water available and the saturation from the dewpoints is also pretty weak. Much of the northern parts of Mississippi and Alabama will see rain, but it’ll be fairly scattered by the time it gets to us. This looks to hit around mid-afternoon to early evening and pass by during the early night hours. Afterwards, winds will shift to the north indicating the cold front’s arrival.

Thursday will be a cooler one with temperatures in the upper 50s to low 60s. Winds will pull from the north and another shortwave trough will bring us colder weather by Friday evening. Temperatures will reach the upper 50s during the day and dip close to the freezing point by Saturday morning. By Sunday, we’ll be in a much cooler weather pattern with temperatures in the upper 40s to low 50s during the day and well below freezing (mid to upper 20s) by early morning. I wouldn’t be surprised if there’s a hard freeze watch or warning for most of us by Sunday.

Hope you all have a good week ahead!
