Two chances for precip, then a pretty stout shot of colder air: Southern MS/AL/LA Weather Forecast – 12/19/22

The next shot for precip shows up Today and tomorrow. This will be a good cold rain. No real threat with this first go-around for frozen precip. High temperatures will be around 50 lows will be around 40. So, too warm for frozen things, but still plenty chilly if you have to be out and about doing last second Christmas shopping.

Here is a quick look at the timeline for rain from the Euro:

It will be pretty chilly. Temperatures may get stuck around 40 to 45 degrees for some spots. So it may ‘feel’ cold and like it ‘should’ be snowing, but it will be too warm. And, in fact, it will also be too warm aloft. The skew-t below shows the forcing will be mainly in the Dendritic Growth Zone. But that closer to the ground – around 4,000ft – the temperature will be well-above freezing.

But that isn’t our only chance to see frozen precipitation. As we move through Thursday and into Friday as the next cold front arrives, there may be just enough lingering moisture to allow for some ice crystal flurries to develop.

So while real snow is looking less and less likely, a few ice crystal flurries still can’t be ruled out. This is why…. Take a look at the estimated radar from the Euro:

Now take a look at the skew-t. Things look pretty warm. Too warm for snow.

But if we sneak in a bit closer, we can see that there is a chance for a few ice crystal flurries.

And then it will be cold. Really cold. And breezy. That cold will last from Friday through Sunday. Looking at the potential wind gusts and wind chills, you can see that we are talking about some seriously cold air.

This is definitely a 4Ps situation. Protect the plants, protect the pets, protect people who don’t ahve easy access to heat, and protect your pipes.

Temperatures will be cold enough to cause hypothermia and even frostbite if you are outside for an extended period of time.

Here is some info from Ready.gov:

Frostbite causes loss of feeling and color around the face, fingers and toes.

  • Signs: Numbness, white or grayish-yellow skin, firm or waxy skin.
  • Actions: Go to a warm room. Soak in warm water. Use body heat to warm. Do not massage or use a heating pad.

Hypothermia is an unusually low body temperature. A temperature below 95 degrees is an emergency.

  • Signs: Shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech or drowsiness.
  • Actions: Go to a warm room. Warm the center of the body first—chest, neck, head and groin. Keep dry and wrapped up in warm blankets, including the head and neck.
