LOUISIANA WEATHER - December 7, 2010

SOUTHEAST LOUISIANA: Today through Friday will be sunny during the day and mostly clear to partly cloudy in the evenings. Tuesday and Friday evening on into Saturday will have a 20 percent slight chance of showers.
Temperatures: Today: 54/34, Wednesday: 54/29, Thursday: 59/42, Friday: 67/52, Saturday: 71/45.
HAZARDOUS WEATHER: A hard freeze and freeze warning will be expiring this mid-morning once temperatures warm above 32 degrees. A fast moving upper level disturbance overnight may produce a very brief period of snow flurries mixed with a cold rain across southwest Mississippi and the adjacent Louisiana parishes. No accumulations are expected.

Small craft should exercise caution mainly across the outer waters east of the Mississippi river delta this morning as winds and seas continue to diminish.

Freezing temperatures are expected once again Wednesday night and Thursday night. A very strong arctic cold front is expected to move through the outlook area late Saturday. This frontal passage will bring a risk of a hard freeze for Sunday night into Monday morning. Strong north winds will likely produce small craft advisory conditions from Saturday through Monday with a possibility of gale conditions after the frontal passage Saturday evening.

SOUTHWEST LOUISIANA:
Today through Friday will be sunny during the day and mostly clear to partly cloudy in the evenings. Tuesday and Friday evening on into Saturday will have a 20-40 percent chance of showers.
Temperatures: Today: 57/35, Wednesday: 56/33, Thursday: 60/46, Friday: 70/55, Saturday: 74/44.
HAZARDOUS WEATHER: No hazardous weather reported at this time.

CENTRAL LOUISIANA: Today through Friday will be sunny during the day and mostly clear to partly cloudy in the evenings with Tuesday evening having a 30 percent chance of snow and rain mix. Friday evening on into Saturday will have a 20 percent slight chance of showers.
Temperatures: Today: 54/30, Wednesday: 54/29, Thursday: 59/40, Friday: 66/52, Saturday: 71/40.
HAZARDOUS WEATHER: No hazardous weather reported at this time.

NORTHERN LOUISIANA: Today will be mostly sunny during the day, with a 40 percent chance of rain/snow mix in the evening. Wednesday has a 20 percent slight chance of light snow during the day and mostly clear in the evening. Thursday and Friday will be sunny during the day with Friday evening having a 20 percent chance of showers and moving on into Saturday.
Temperatures: Today: 54/34, Wednesday: 52/31, Thursday: 56/41, Friday: 61/52, Saturday: 64/40.
HAZARDOUS WEATHER: A strong upper level storm system will move out of the Rockies today and into the four-state region tonight. While returning moisture is very limited with this system, strong cold air aloft will support the possibility of light rain mixing with snow, initially this evening, near and northwest of the I-30 corridor of northeast Texas, southeast Oklahoma and southwest Arkansas. By late evening into the overnight hours tonight, the precipitation will likely become all light snow across all but the deep east Texas lakes area. Given the fact that the system will have a limited amount of moisture to work with and that the system will be east of the region by mid morning Wednesday, any chances for snowfall accumulations will be brief and likely confined to areas along and north of a line from Clarksville Texas, to Texarkana Arkansas, to Monroe Louisiana. Snowfall amounts overnight along and north of this line could approach one half inch. South of this line closer to the I-20 corridor of northeast Texas and northern Louisiana, little if any accumulation can be expected. Ground temperatures remain very warm so the snowfall that can accumulate will likely be confined to elevated objects and grassy surfaces.
