Downpours Soaking Lower Mississippi Valley

Tropical downpours will encompass more of the lower Mississippi Valley on Saturday, creating slowdowns for holiday travelers.

Drenching showers and thunderstorms seen along the coasts of Texas and Louisiana on Friday are now soaking the lower Mississippi Valley.

The downpours are targeting Lake Charles, Baton Rouge and New Orleans, Louisiana, and Vicksburg, Mississippi.

Rain totals in Lake Charles since Friday night have eclipsed 7 inches. A National Weather Service employee reports the resultant flood waters entered a home in the city.

The unsettled weather may lead to travel delays for holiday travelers on the roads and at the airport with delays possibly continuing into the holiday weekend.

Other flash flooding incidents may unfold in urban and low-lying areas. Even if flooding does not ensue, motorists will be at risk for reduced visibility and the danger of vehicles hydroplaning at highway speeds will increase.

Looking ahead to the remainder of the holiday weekend, the disturbance triggering the downpours is projected to be picked up by a cold front slowly swinging across the Plains.

As a result, widespread showers and thunderstorms will center on northeastern Louisiana, eastern Arkansas, northwestern Mississippi and western Tennessee Saturday night.

This includes Monroe, Louisiana; Greenwood, Mississippi, and Memphis, Tennessee.

Numerous showers and thunderstorms will center on the Tennessee and Ohio Valley on Sunday, while the coverage of thunderstorms will be less in the lower Mississippi Valley.

There is some good news for those in Texas and across the lower Mississippi River Valley with outdoor plans on Labor Day.

Dry weather and partial sunshine will be the theme across much of the area for Monday, making for better conditions for barbecues and sporting events when compared to Saturday and Sunday.

However, a few showers and thunderstorms may still dot the immediate Gulf Coast on Labor Day.

A complete washout should not be expected though as thunderstorms will likely be brief, only causing temporary issues for outdoor festivities.
