Wednesday Weather Update: What SWLA Can Expect This Weekend

Lake Charles, Louisiana (KNGT-FM) - As we get closer to the weekend, the forecasts and models should start to align, and we will get a clearer picture of how the frigid, freezing weather will affect us here in Southwest Louisiana. We've got the Wednesday update for you...

As with any storm, as we get closer to the arrival time, meteorologists will have access to more reliable short-term models. That also means that Air Force Reserve Hurricane Hunters will be able to fly missions to gather data over the Pacific Ocean, which will help improve forecast accuracy.

REMINDER: When severe or winter weather threatens Southwest Louisiana, it’s best to trust local meteorologists. Jacob Durham, Wade Hampton, and Max Logano at KPLC, along with the National Weather Service, use reliable data and experience to give accurate, level-headed forecasts for our area. Unlike fear-mongering “meteorologists” on Facebook, local experts focus on facts, not clicks.

So what do the impacts look like for Southwest Louisiana as of WEDNESDAY MORNING?

Wednesday Morning SWLA Freezing Weather Update - January 21st

According to Wade Hampton with KPLC, there is still a lot of uncertainty about temperatures, which will determine what kind of weather we see.

Forecasters are confident that rain will move into the area Saturday and last into Sunday. The best-case scenario would be a cold, steady rain. The worst-case scenario would be rain changing into freezing rain, which can cause ice to form on roads, bridges, and power lines.

The greatest risk for ice is north of Interstate 10, with conditions becoming more dangerous farther north into central and northern Louisiana. Travel in those areas could be difficult or even impossible, especially along Interstates 20, 30, and 40. Anyone planning to travel north is urged to postpone trips unless absolutely necessary.

Here in Southwest Louisiana, the forecast is less certain. Ice could reach as far south as I-10 if temperatures drop low enough before the rain moves out. A difference of just a few degrees could mean the difference between all rain and icy conditions.

With today being the first anniversary of the 2025 Louisiana snowstorm, there has been a lot circulating about the potential for snow. This system is not expected to bring snow like last year’s storm. That is because warmer air higher in the atmosphere will prevent snow from forming. Instead, colder air near the ground could lead to freezing rain, which is often more dangerous.

As of Wednesday Morning, Hampton says the chance for moderate impacts remains low along I-10 at 5 to 10 percent, but rises to 40 to 50 percent in northern Vernon Parish.
