SOUTHEAST LOUISIANA: Today has a 70-80 percent chance of showers throughout the day. Thursday will be cloudy throughout the day. Friday through Sunday is forecast to be sunny and clear.
Temperatures: Today: 58/33, Thursday: 46/27, Friday: 53/31, Saturday: 58/36, Sunday: 66/44.
HAZARDOUS WEATHER: Another cold front is expected to move through the area this evening. Rain is expected to spread across most areas this afternoon and evening. There will be sufficient cold air moving into southwest Mississippi and the adjacent upper parishes of southeast Louisiana to support a mix of light sleet and light snow during the period from about 8 pm to midnight, then a slight chance of light snow or flurries from about midnight to 3 am. Any snow or sleet accumulations are expected to be less than one half inch at this time and mainly in grassy areas. The main threat area for any wintry precipitation will be north of a line from near Baton Rouge to Franklinton with the best chance across southwest Mississippi and the parishes north of Baton Rouge. One concern could be black ice on elevated roadways if freezing temperatures move in before the bridges have completely dried.
Another issue with this system will be winds over the coastal waters and tidal lakes. Small craft advisory conditions due to strong north winds are expected to develop around 9 pm tonight with the frontal passage and will remain hazardous for Thursday morning.
A moderate to hard freeze is expected Thursday night and Friday night, mainly in areas north and west of the Louisiana tidal lakes and across southern Mississippi. A light freeze is expected over many areas south of Lake Pontchartrain as well Thursday night and Friday night.
SOUTHWEST LOUISIANA: Today has a 90 percent chance of showers during the day decreasing to 30 percent chance in the evening. Thursday through Sunday will be sunny during the day and mostly clear in the evenings.
Temperatures: Today: 50/27, Thursday: 43/24, Friday: 53/27, Saturday: 60/35, Sunday: 65/48.
HAZARDOUS WEATHER: An arctic cold front will move across the region this morning into the afternoon. Widespread rain is expected this afternoon with rainfall totals up to one-half of an inch. Temperatures falling to near or below freezing late this afternoon may transition the rain to a wintry mix of light freezing rain, light sleet and light snow across the lakes region of southeast Texas and central Louisiana. Little if any ice or snow accumulation is expected. However, any ice or snow accumulation that does occur along with rain water freezing onto roadways may cause some icy bridges and overpasses.
A hard freeze is expected Thursday morning north and west of a line from Cameron to Marksville. Another hard freeze is anticipated Friday morning for all areas, with low temperatures around 20 degrees in the lakes region of southeast Texas and central Louisiana and low to mid 20's elsewhere.
CENTRAL LOUISIANA: Today has a 90 percent chance of rain/sleet mix during the day with a decrease to 50 percent in the evening. Thursday through Sunday is forecast to be sunny during the day and clear in the evening.
Temperatures: Today: 40/26, Thursday: 39/20, Friday: 51/26, Saturday: 59/32, Sunday: 66/45.

NORTHERN LOUISIANA: Today has a 100 percent chance of snow and sleet with a decrease to 30 percent in the evening. Thursday through Sunday are forecast to be sunny during the day and mostly clear in the evenings.
Temperatures: Today: 34/19, Thursday: 34/19, Friday: 44/26, Saturday: 58/33, Sunday: 67/43.
HAZARDOUS WEATHER: A winter storm warning covers the area from the Interstate 20 corridor and northward. Areas of snow will increase in coverage and intensity from west to east today, overspreading much of the region during the day. Some of the snow will be mixed with sleet and rain in the morning generally along the Interstate 20 corridor, before temperatures fall to or below freezing by afternoon, as the deepening cold air forces a changeover to all snow by afternoon. Total snow accumulations today will range from 6 to 8 inches, with isolated higher amounts, across southeast Oklahoma and the northern sections of southwest Arkansas, north of an Ashdown, to hope and Prescott line. Snowfall accumulations of 4 to 6 inches will be possible across the I-30 corridor of northeast Texas and the remainder of southwest Arkansas. Farther south towards the Interstate 20 corridor of east Texas and north Louisiana, snowfall accumulations of 2 to 4 inches, with isolated higher amounts, will be possible. Minor sleet accumulations near a tenth of an inch will also be possible.
Lingering snow and ice on roads will make travel hazardous through Friday morning due to minimal melting Thursday, as temperatures struggle to reach the freezing mark. This will result in black ice formation overnight Thursday. Temperatures are expected to warm above freezing area-wide Friday and Saturday, thus melting the snowpack for the coming weekend.
