For a few days now the National Weather Service and Baton Rouge-area meteorologists have advised that there's the potential for snow and sleet to fall late Thursday through Friday morning.

Southeast Louisiana hasn't experienced snow accumulation since Feb. 10, 2012, when about 1 inch fell in the Baton Rouge area. The most snow ever recorded in Baton Rouge was 12.5 inches in February 1895, according to state Climatologist Barry Keim.

Here's a rundown of what we know -- and don't yet know -- about the timing and impact of possible wintry precipitation.

What we know

-- The National Weather Service issued a winter weather advisory for the Baton Rouge area beginning Thursday night, with the possibility of snow Friday morning. The winter weather advisory goes into effect at 9 p.m. Thursday and will last until noon Friday.

-- The winter weather advisory includes Pointe Coupee, West Feliciana, East Feliciana, St. Helena, St. Tammany, Iberville, West Baton Rouge, East Baton Rouge, Ascension, Livingston and Tangipahoa parishes.

-- According to the National Weather Service, a mix of rain and sleet could begin late Thursday night and become snow Friday morning. Any wintry mix would reduce visibility and impact the Friday morning commute. Snow showers, if they occur, should end before noon.

-- As of Thursday afternoon, National Weather Service meteorologist Alek Krautmann in the Slidell office said that the agency had already received a few reports of sleet mixed into rain. He said temperatures won't drop low enough for water to freeze on roads. 

Baton Rouge snow probabilities Thursday for Friday

As of late morning Thursday, the National Weather Service's Weather Prediction Center says there's a 40-50 percent chance in the Baton Rouge area of seeing at least one inch of snow accumulation from 6 p.m. Thursday through 6 p.m. Friday.

-- Per the National Weather Service: "So far little in the way of ground accumulation is expected, however some grassy areas and elevated surfaces and roadways could see some light accumulation before returning to rain during the afternoon before ending." This means widespread issues on roads shouldn't occur.

-- Schools have started announcing closures for Friday. Follow along here.

What we don't know (yet)

-- How much snow will fall in the area, if any. As the NWS says, "the forecast challenge is where the advancing cold air meets up with the moisture that has brought us the (rain) over the last few days."

-- When exactly the rain might turn to sleet and when the sleet might turn to snow (if it occurs). The best bet is to stick with the timeframe of the winter weather advisory, which begins at 9 p.m Thursday and ends at noon Friday.
