Tonight – Passing showers. Cloudy and cold. Wind chills in the 20s and 30s. Lows near 38.
Tomorrow – Chilly with some broken clouds. Light north wind. Rain possible. Highs near 48.
Extended – Please monitor Monday. Cold rain will eventually transition into freezing rain and sleet by mid-morning. The probability for freezing rain and ice continues to climb. If the event verifies, many roadways will become icy. Numerous road closures will be probable. If ice accumulates [nearly a 0.25″ or greater], expect spotty power outages with dangerously cold temperatures by Monday night. Overnight lows will rapidly drop into the mid 20s. Wind chills could reach the teens and single digits. We’ll likely see a Hard Freeze. Cover exposed pipes this weekend and have a plan for your pets and tropical plants.
Because of the already subfreezing temperatures, any liquid precipitation will likely freeze on contact Monday night and early Tuesday. Be very cautious while driving over elevated surfaces such as bridges. All wet surfaces and puddles will quickly freeze overnight and become slick. “Black Ice” -a transparent coating of ice found on a road or other paved surface – could be big issue for Tuesday morning. Be careful walking on sidewalks and driveways.
As for snow, the event will mainly be ice. We may see a few flurries on the backend. The majority of snow will be sitting across central and northern Louisiana. Sleet accumulations are definitely probable for our Florida parishes and southern Mississippi.
