Severe Weather Threat Increases For Tuesday
One look at the regional weather radar from the National Weather Service and you don't have to be a meteorologist with a college degree figure out it's going to rain. This liquid sunshine is currently moving across the state courtesy of a cold front and low pressure system that is centered in Texas.
During the day today the cold front and low pressure system are forecast to move slowly to the south and east. The front is forecast to stall along the Louisiana Gulf Coast during the evening hours. This instability in the atmosphere and the location of the sub-tropical jet stream aloft will be conducive for the development of significant showers and thunderstorms.
The set up for Tuesday according to the Storm Prediction Center will put most of the southern two-thirds of the state in the enhanced to slight risk category for severe weather. This means the possibility of severe thunderstorms, damaging winds, hail and possible tornadoes will exist in the forecast area for much of the day. The northern third of the state will have a marginal risk for severe weather.
While the southern part of the state might take on a more significant threat for severe weather the northern part of Louisiana will get the heaviest rainfall. Forecasters are projecting a storm total of almost an inch in the coastal parishes south of I-10. In Central Louisiana rainfall amounts could be an inch to an inch and half. While the I-20 corridor could see rainfall totals in excess of two inches before the system finally pushes off to the east later this week.
