A potent storm system will bring a second round of winter weather to south Louisiana on Tuesday and Wednesday morning. A Winter Storm Warning is in effect for all of south Louisiana from 6:00 a.m. Tuesday through 6:00 a.m. Wednesday.

Summing a "Reader's Digest" version of the winter storm ahead, isolated showers will begin to develop throughout the area overnight. By morning, freezing rain and sleet will spread out over the coast and begin to transition to sleet and snow by Tuesday afternoon and evening. Tuesday night into early Wednesday morning will give us the highest chances of accumulating snowfall. The Capitol Area could see up to a quarter inch of ice and 1-3 inches of snow by Wednesday. 

Expanding on the forecast, we'll see clouds the rest of this evening, with temperatures falling fast through the 40s and 30s. Isolated showers are possible around 10:00 tonight, but cloud cover will be more widespread, than the rain.

As you wake up tomorrow, you'll notice showers developing over SW Louisiana; this will be a mixture of rain, freezing rain and sleet. A few flurries may start to fall in extreme east Texas.

Moving into mid-morning, temperatures hardly budge from our morning lows in the upper-20s and chances of freezing rain and sleet continue over south Louisiana. As the front continues southward, snow will become more widespread in central Louisiana and northern edges of Acadiana.

Roads will increasingly become more frozen throughout the area through mid-morning.

Around mid-afternoon is when the snowy-transition really begins to kick in for places of south Louisiana. Accumulations of snow could begin to develop in south Mississippi and northern parishes of SE Louisiana.

Travel will become extremely difficult through the afternoon and evening. It will be a good time to stay home.

Tuesday night will bring the best possibilities of snowfall to the entire corner of our state. (Snow-lovers, do not get discouraged if you do not see the flurries until tomorrow night. It will come.)

By Wednesday morning, the wintry precipitation begins to exit the state. However, clouds will likely stay stubborn through most of Wednesday, while a few flurries could still fall through mid-morning.

Overall, most of the weather models agree that there will be accumulating, wintry mix in south Louisiana. Right now, it looks like parishes north of the I-10/I-12 corridor will see a tenth to a quarter inch of ice through Tuesday afternoon, then add 1-3 inches of snow through Wednesday morning.

Along the coast, chances of ice are higher due to the temperature contrast between cold and warm air. A forecast of a quarter inch to half inch of ice is possible south of East Baton Rouge parish, with an inch or less of snow accumulating through Wednesday morning.

Regardless, the chances of measurable snow are high throughout the entire region.

On top of the slippery forecast, Baton Rouge could see a hard freeze and record lows on Wednesday morning; another hard freeze is likely on Thursday morning.
