Winter: Round 2

Another winter storm is preparing to move toward Acadiana on Tuesday. This one may have more moisture associated with it, and may bring more frozen precipitation over the coastal sections.

Cold air is already moving southward from the Midwest. The cold front will pass through Acadiana around midday today and temperatures will start to fall into the 40s by this afternoon. This evening temperatures will stay in the 30s with freezing conditions holding off until the early morning hours Tuesday. Light freezing rain will move in from the west around dawn. Freezing rain will cover more areas during the morning including the coastal parishes.

By the middle of the day Tuesday, temperatures will hover in the mid to upper 20s with freezing rain continuing over the southern sections, while there will be a transition to sleet then snow over areas north of I-10. Later in the afternoon, snow will be likely over the northern half of Acadiana with a sleet/snow mix over the southern sections. Freezing rain will continue south of the Intracoastal Waterway.

Accumulations of sleet and snow could be around 1-2 inches over a large part of Acadiana with some isolated locations seeing up to three inches. Ice accumulations will range from a trace over northern sections, to 1/10" along I-10, and 1/4-1/2" of ice accumulation is possible over the southern sections. Ice thickness over 1/4" can bring down small branches and power lines.

Temperatures will remain below freezing Tuesday night through the middle part of the day Wednesday. Any roadways, or bridges that become iced over Tuesday will remain that way until the afternoon Wednesday. Traveling will be treacherous starting Tuesday morning and lasting through Wednesday. Temperatures will consistently stay above freezing starting Thursday.
