LOUISIANA WEATHER - November 8, 2011

EMERGENCY ALERT SYSTEM TEST:

As part of a larger effort to strengthen the nation’s preparedness and resiliency, the Federal Communications Commission (FCC) and the U.S. Department of Homeland Security's Federal Emergency Management Agency (FEMA) will conduct the first nation-wide test of the Emergency Alert System on November 9th, at 1 P.M. Central Time. Testing the Emergency Alert System plays a key role in evaluating and improving the systems needed in place to ensure our nation is prepared for all hazards and that people within its borders are able to receive critical and vital information through the system.

 

SOUTHEAST LOUISIANA: Today will be mostly cloudy during the day with the evening having a 50 percent chance of scattered showers continuing on into Wednesday. Thursday through Saturday is forecasted to be sunny and clear.
Temperatures: Today: 81/66, Wednesday: 78/48, Thursday: 69/37, Friday: 66/41, Saturday: 75/57.
HAZARDOUS WEATHER:  The chance for widespread hazardous weather is low.  However a few strong thunderstorms, capable of producing strong wind gusts and frequent lightning, are possible tonight and possibly early Wednesday, over western portions of the area, mainly west of a line from McComb, Mississippi to Houma, Louisiana.

 

Small craft advisory conditions are expected to develop in the wake of the cold front Wednesday night and persist into Thursday night.

 
SOUTHWEST LOUISIANA: Today has a 30 percent chance of thunderstorms during the day with an increase to 60 percent at night.  Wednesday through Saturday is forecasted to be sunny during the day and partly cloudy to clear in the evenings.
Temperatures: Today: 78/61, Wednesday: 68/42, Thursday: 65/38, Friday: 64/49, Saturday: 74/62.
HAZARDOUS WEATHER:  Thunderstorms after midnight could reach severe limits in advance of a strong Pacific cold front.  Once the front passes late tonight, the severe threat should end.  About an inch of rainfall should be common from this system.

 

There will be cool, chilly nights and mild days into this coming weekend. Rain chances return on Monday as another Pacific front approaches.

 
CENTRAL LOUISIANA:  Today has a 20 percent chance of showers during the day with an increase to 70 percent at night.  Wednesday through Saturday is forecasted to be sunny during the day and partly cloudy to clear in the evenings.
Temperatures: Today: 82/52, Wednesday: 65/42, Thursday: 64/33, Friday: 64/39, Saturday: 70/57.
HAZARDOUS WEATHER:  

Thunderstorms after midnight could reach severe limits in advance of a strong Pacific cold front. Once the front passes late tonight, the severe threat should end.  About an inch of rainfall should be common from this system.

 

There will be cool, chilly nights and mild days into this coming weekend. Rain chances return on Monday as another Pacific front approaches.

 
NORTHERN LOUISIANA:   Today has a 70-90 percent chance of severe thunderstorms throughout the day. Wednesday through Saturday is forecasted to be sunny during the day and partly cloudy to clear in the evenings.
Temperatures: Today: 78/49, Wednesday: 64/39, Thursday: 63/33, Friday: 65/41, Saturday: 72/59.
 
HAZARDOUS WEATHER:  A strong upper level storm system will emerge out from the
southern Rockies and into the southern Plains, causing showers and thunderstorms to intensify this afternoon during peak heating as they enter extreme eastern Texas, north Louisiana, and southwest Arkansas.  Given the strong wind shear and forcing in place, some of these storms may become severe, capable of producing damaging winds and isolated tornadoes. However, the severe weather threat will be dependent on the extent of instability in place, which could be inhibited by cloud cover and showers that may develop ahead of the primary band of thunderstorms. In addition to the severe thunderstorm threat, locally heavy rainfall will be possible area wide, with rainfall amounts of one to three inches expected, with isolated higher amounts possible. The showers and thunderstorms will diminish from west to east this evening, with cooler and drier air filtering southeast behind a cold front.
