Honestly, if you've lived in Northwest Louisiana for more than a week, you know the drill. One day you're wearing a light jacket at the Red River Revel, and the next, you're digging through the attic for that one heavy coat you bought for a trip to Colorado. The weather forecast shreveport la 7 day outlook is basically a rollercoaster of humidity and sudden temperature drops that would give anyone whiplash.
Right now, we're sitting at a crisp 39°F. It's clear out. Peaceful. But don't let that midnight calm fool you.
The Immediate Outlook: Cold Mornings and Deceptive Sun
Today, Sunday, January 18, 2026, we hit a high of 48°F. Not exactly tropical, but with the sun out and an 8 mph breeze coming from the west, it felt decent if you stayed in the light. Tonight is where the "fun" starts. We are bottoming out at 25°F.
If you haven't covered your pipes or brought the plants inside yet, you're cutting it close. The humidity is sitting at 35%, which is remarkably dry for us. Usually, you can practically drink the air in Shreveport, but this dry cold is the kind that chaps your lips before you even realize you're thirsty.
Tomorrow, Monday, January 19, things "heat up" a bit—if you can call 56°F hot. It’ll be partly sunny, but the clouds will start moving in by evening. We’re looking at a 10% chance of rain, which basically means you might see a stray drop on your windshield, but don't count on it for the garden.

Why the weather forecast shreveport la 7 day is Shifting
Midweek is when the pattern really breaks. Tuesday stays relatively steady with a high of 52°F and a low of 32°F. It’s that classic "in-between" weather where you can't decide if you need the heater or just a really good sweater.
Then comes Wednesday.
Wednesday, January 21, is when the umbrellas need to come out. We are looking at a 70% chance of rain during the day. The temperature stays around 49°F, but the humidity is going to skyrocket to 94%. It’s going to be that heavy, grey, damp cold that just soaks into your bones.
The interesting part? Thursday stays damp. Another 25% chance of light rain with a high of 54°F. We aren't seeing the sun much this week once Tuesday wraps up.

The Weekend Breakdown
- Friday, Jan 23: High of 54°F. Cloudy all day. Rain chances jump to 75% overnight.
- Saturday, Jan 24: This is the day to watch. The high is only 31°F. Let that sink in. We are going from a high of 54°F on Friday to a high of 31°F on Saturday with heavy rain (75% chance).
- Saturday Night: Dropping to 25°F with lingering light rain.
When you have a high below freezing and a 75% chance of precipitation, that's when local grocery stores start running out of bread and milk. Whether it's "heavy rain" or something slightly more frozen depends entirely on a two-degree swing that the models are still fighting over.
Complexity of the Ark-La-Tex Basin
Shreveport weather is weird because of where we sit. We get the moisture from the Gulf, but we’re far enough north that the Canadian fronts don't lose their teeth before they hit us. According to experts at the National Weather Service in Shreveport, these late January systems often involve "wedge" patterns where cold air gets trapped near the surface while warmer, moist air slides over the top.
That is exactly what causes our ice storms. While the weather forecast shreveport la 7 day currently calls for "heavy rain" on Saturday, keep a very close eye on those temperatures. If that 31°F high drops even a little, we aren't talking about a rainy Saturday; we're talking about a mess on I-20.
Preparation is Basically a Lifestyle
Look, don't wait until Friday night to check your antifreeze.

Basically, you've got about 48 hours of "easy" weather before the dampness and the deep freeze move in. If you're planning on being out by the boardwalk or heading over to Bossier this weekend, Saturday looks like a total washout—and a cold one at that.
The wind is going to shift to the North at about 11 mph by Saturday, which means the wind chill is going to be brutal.
Next Steps for the Week:
- Drip those faucets Tuesday night and Saturday night.
- Plan for rain on Wednesday; it's the most certain "wet" day of the early week.
- Watch the Saturday numbers. That 31°F high is the threshold for a lot of potential headaches.
Stay warm, Shreveport. It's going to be a long week.
