LOUISIANA WEATHER: January 27, 2010



SOUTHWEST LOUISIANA:
Today will be sunny with highs in the upper 60’s during the daytime hours. Tonight will be partly cloudy with a low near 51°. Thursday has a 20 percent chance of thunderstorms with an increase to 70 percent in the evening, which will move into Friday. Saturday and Sunday will be sunny during the day and mostly clear in the evening.
HAZARDOUS WEATHER: A chance for showers and thunderstorms will return over interior southeast Texas into central Louisiana Thursday afternoon, overspreading the entire forecast area Thursday night into Friday. This activity will develop ahead of a potent storm system currently just off the Baja peninsula that will be advancing east through the southern plains into the Mississippi valley. Significant rains are anticipated with this system with 2 inches common along the Interstate 10 corridor, possibly approaching 3 inches over central Louisiana and interior southeast Texas. Isolated higher amounts will be possible. While heavy rains remain the primary threat, this system does have severe weather producing wind profiles. At this time however instability appears limited and will hamper any severe thunderstorm development. A steady increase of winds over the coastal waters will bring the potential need for issuance of a small craft advisory for Thursday and Thursday night.

The Sabine River at Deweyville is currently at 24.16 feet (minor flood stage). The river will remain at this level for the next few days. Flood stage is 24 feet. At 24-25 feet, minor lowland flooding may occur. Low-lying roads in southwestern Beauregard Parish including Robert Clark Road may have water over them.

Saturday and Sunday will be sunny during the day and mostly clear in the evenings.
HAZARDOUS WEATHER: An area of low pressure and associated frontal system will move through the region on Friday. Showers and thunderstorms will accompany this weather system. Strong to possibly severe thunderstorms will be possible. The main threat would be damaging winds, however, an isolated tornado cannot be ruled out. In addition, one to two inches of rain will be possible as this system moves through the area.
