WebEOC Incident: 15-007 Winter Weather – Statewide, March 4 – 5, 2015




SITUATION:   An arctic cold front will move through the area Wednesday night with the possibility of a wintery mix across most of Louisiana. This system should move out of the area by Thursday afternoon bringing slightly warmer temperatures back into the state for the weekend.




Southeast Louisiana:  A strong arctic front will bring cold air back to the area for the end of the work week. There is a very low risk of light freezing rain developing Thursday morning across portions of southeast Louisiana to the north of Baton Rouge. If freezing rain develops, little if any ice accumulation is expected and impacts should be minimal.


Southwest / Central Louisiana:  A few showers and even an isolated thunderstorm is anticipated to develop this evening as a cold front approaches from the north. A wintery mix of light rain, sleet and periods of light freezing rain are possible in northern portions of central Louisiana, however total ice accumulations will be less than 0.05 inches. Temperatures are expected to fall into the 20’s late Thursday night into Friday morning, mainly north of the I-10 corridor and while the interstates and major highways will likely be dry during this time, some rural roads with little traffic could have some wet spots that could freeze in these temperatures. There will also likely be a hard freeze for nearly the entire area Thursday night into Friday morning.

North Louisiana:   A Winter Storm Warning remains in effect from 6:00 pm today to 9:00 am Thursday as rain changes to freezing rain and then to a wintery mix of freezing rain, sleet and snow by late this evening and especially after midnight. Ice accumulations of one quarter to half of an inch are possible along and south of the Interstate 20 corridor by daybreak. Where snow occurs we could see accumulations of one to three inches on top of surfaces that may already have ice accumulationsBy late tonight through Thursday, travel will become very hazardous and numerous power outages are likely, however wintery precipitation will be ending by the afternoon on Thursday. Lows tonight below 20 degrees and highs near or below 32 degrees are likely for portions of northeast Louisiana into Friday morning with wind chill temperatures expected to be in the single digits.
