The second winter storm within a week impacted Acadiana Tuesday with mostly sleet and freezing rain leaving an icy glaze across the entire area and closing most bridges and major roads.
Ice accumulations were generally in the 1/4" range along and south of the I-10 corridor with icy accumulations closer to 1/2" to 1" across the northern parishes of Acadiana.
Farther to the north snow mixed with the ice producing accumulations of 1-2" across Central Louisiana into Rapides and portions of Beauregard, Vernon, and northern Avoyelles Parishes.
Snow that fell across the area traversed a warm pocket of air several thousand feet up allowing it to melt, but either refroze in the lower 2,000 feet of the atmosphere or upon contact with the ground.
Although precipitation was ending early Tuesday evening, the icy accumulation and subsequent hazardous roadways are expected to stay until temperatures get above freezing...which may only be for a few hours Wednesday afternoon, depending on any lingering cloud cover.
Bitterly cold temperatures in the mid-20s accompanied by wind chills in the lower teens, were common across the region Tuesday.
Lows Wednesday morning will likely dip into the lower 20s across most areas and the upper teens for northern-most portions of Acadiana.
Computer model forecasts are indicating sunny skies will return to the area Wednesday, but lingering clouds could become an issue, hampering any significant melting of the ice.
Temperatures will again drop into the low-mid 20s Wednesday night into Thursday morning.
Thereafter, Acadiana will thaw out with highs Thursday reaching the low-mid 50s under sunny skies.
Temperatures will climb into the 60s Friday and lower 70s Saturday before the next front arrives this weekend. The next front will bring briefly cooler, but not colder conditions Sunday.
