Winter Weather Advisory

Posted: Updated:

Arctic air is plunging southward today and winter is making a big return. Already, snows and a wintry mix are occurring over northern and central Louisiana with generally light rain over the immediate Acadiana area prior to sunrise. Temperatures will continue falling into the lower 30s by this afternoon with upper 20s possible as early as 5pm over areas north of I-10. Most of the precipitation will be light. Rainfall totals should be less than a tenth of an inch, but as temperatures approach freezing, some icing of bridges and overpasses will be possible making travel hazardous. 

Roadways are already being closed over northern Louisiana and northeastern Texas. I-20, I-220, and I-49 will be impacted as well as other U.S. and state highways. Traveling over the northern part of the state is strongly discouraged. We will continue to watch for any issues or closures over the immediate Acadiana area throughout the day and those closures will be posted on our website as well as our social media pages.

Temperatures should be dropping to near freezing this afternoon. With precipitation still forecast to be in place, we can expect rains to change over to freezing rain mixed with sleet. As we progress toward the late afternoon early evening hours, most areas will change over to light snow. Only minor accumulations are expected with some areas receiving up to one inch of snow. As far as any sleet or icing, accumulations should be less than one tenth of an inch, mainly on elevated surfaces. Any minor changes in the forecast could mean significant shifts in impact, so stay up to date with the latest forecasts. Wind chills will drop into the teens and 20s. Not only do we have a Winter Weather Advisory in effect, but also a Wind Chill Advisory. Feels like temperatures will be hovering in the teens, and perhaps the single digits by this evening and overnight.

 

 

 

As the precipitation ends and the skies clear tonight, overnight temperatures are expected to plunge into the lower 20s, even with wind speeds staying up. A few areas over central Louisiana could drop into the upper teens. Wind chills will run between 8-18 degrees. Sunny skies are expected for Wednesday, but temperatures won't recover. Expect highs to only reach the mid to upper 30s. With temperatures expected to drop to near 20 again by early Thursday morning, there will be issues with pipes. Hopefully this was taken care of during the last hard freeze a couple of weeks ago.  We should see temperatures recover into the 40s by Thursday, 50s by Friday, and 60s by the weekend.
