The National Weather Service in Lake Charles is expecting to upgrade the winter storm watch to a winter storm warning this afternoon for the entire region. Snow, sleet, and freezing rain will be possible on Tuesday, with the threat starting in the morning, and continuing through the afternoon and evening. It could linger after midnight early Wednesday morning in south central Louisiana, according to a press release from the National Weather Service-Lake Charles.
Total snow accumulations of 2-4 inches is possible in east Texas and central Louisiana, ranging to around 1 inch for the I-10 corridor of southeast Texas and southwest and south central Louisiana.
Total ice accumulations of around one-quarter inch is possible for the I-10 corridor of southeast Texas and southwest and south central Louisiana, ranging to one-tenth of an inch in east Texas and central Louisiana. Of note, south central Louisiana may be in line to see a more significant ice accumulation.
Due to windy conditions Tuesday, power outages may become more numerous for the I-10 corridor, especially in southwest and south central Louisiana.
Due to temperatures below 20 F Wednesday morning, snow and ice will be slow to melt off the bridges and overpasses on Wednesday. At the earliest, the winter precipitation could be melting by Wednesday afternoon, but that will only be if temperatures warm up enough. Currently we are forecasting highs in the mid to upper 30s, which may not be enough to melt all of the snow and ice.
