Winter Weather Advisory & Freeze Warning issued for portions of Acadiana

Posted: Updated:

It is looking pretty likely that most of Acadiana will see the rain switch over to snow at times Friday morning.

Thus a Winter Weather Advisory has been issued for central Acadiana beginning tonight at midnight and lasting until noon Friday.

I am expecting temperatures to dip close to the freezing mark around 4-5am which is when we could begin to see the first snow flakes.

Temperatures will remain near or just above the freezing mark through 9-10am allowing for whatever moisture left to fall as snow.

After 10am temperatures will start to warm back to the lower 40s causing the snow to turn back over to rain.

All rain/snow should come to an end across Acadiana around lunchtime.

Now the roads are still fairly warm and wet thanks to all the rain we have been receiving the past couple days so I am not expecting any real issues or concerns on the major roadways as the snow should melt on contact.

However, bridges and overpasses cool faster leading to the possibility for minor accumulation and black ice to develop on them, including the basin bridge.

That said this is still a very tricking forecast, as all snow events in South Louisiana are, as there are still a lot of different factors that have to come together just right.

Right now we continue to have light scattered showers working across the region as the result of a shortwave moving over the region, so check we have the moisture in the atmosphere.

Over north Louisiana there is a dry cold front where the colder and drier air is located.

As this front slides down over Acadiana it will cause temperatures to fall dropping into the low to mid 30s by Friday morning. Check to freezing temperatures.

A Freeze Warning has even been issued for northern Acadiana as they will have the best chance for seeing a light freeze tonight with near freezing temperatures for several hours.

Thus as this colder air arrives that is when the rain will switch over to big wet snow flakes making for a very picturesque scene for Acadiana.

But as a mentioned this front also will be pushing drier air over the region causing the moisture to start evaporating before it makes it all the way to the surface.

This is the biggest question mark with Friday morning forecast.

It the drier air arrives faster than the models are expecting than we could see very little in forms of snow or wintry precipitation.

But if this drier air takes it time moving over Acadiana that could lead to more time for snow showers producing minor accumulations(up to an inch) on the grassy areas and maybe even some spots of less traveled roadways.

So, the biggest takeaway is to just take it easy on the roadways Friday morning and give yourself plenty of space between you and the car in front of you and do not slam on the brakes as that leads to more skidding.

Once the rain/snow ends Friday afternoon cold becomes the main issue with a hard freeze likely for all of Acadiana Saturday morning which could cause exposed pipes to freeze and burst. 

Plants and pets will also need to be protect for these freezing temperatures.

Another light freeze will be possible Sunday morning as well but during the afternoons this weekend the weather will improve with lots of sunshine and highs in the mid 50s.
