Tornado rolls trailer in Louisiana leaving 2 injured before Thanksgiving

A swath of rain and thunderstorms are threatening to slow down motorists from the Ohio Valley to the Gulf Coast in the days prior to Thanksgiving. The corridor will be on the mild side of a storm that is poised to unleash an all-out blizzard from Colorado to the Upper Peninsula of Michigan.

While this means roadways will be soaked from Louisiana to Ohio, as opposed to slippery and snow-covered, drivers should still expect disruptions through these states.

The combination of the rain reducing visibility and heavy volume of traffic on the roadways is likely to increase travel times along stretches of interstates 10, 20, 40, 55, 59, 64, 65, 69, 70, 75 and 90.

Motorists are encouraged to check their windshield wipers to ensure they're in good working order before heading out.

Rain will spread from the middle and lower Mississippi Valley through the Ohio and Tennessee River valleys during Tuesday night.

The major hubs of St. Louis and Detroit will be impacted by the wet weather Tuesday night. Winds are also expected to increase during this time, making for turbulent conditions for arrival and departure flights.

The greatest risk for severe weather is expected from northern Missouri and southern Illinois to central Louisiana.

Thunderstorms that fire in this region will be capable of producing damaging winds and even a few isolated tornadoes. The cover of darkness will add danger to the severe weather potential.

Emergency management reported two occupants of a trailer were injured after it rolled in a possible tornado near Hemphill Road in Baskin, Louisiana around 6:00 p.m. CDT. Reports say several homes were damaged and power lines are down in the area.

Another confirmed tornado crossed into southeast Richland Parish and passed near Delhi, Louisiana around 7:45 p.m. CDT.

A tornado watch has been issued for part of the region until 10 p.m. CST Tuesday due to the risk for severe weather.

Brief, intense downpours are also of concern for those traveling through the region.

Remember to seek shelter indoors and away from windows at the first clap of thunder. A thunderstorm does not have to be severe to produce potentially deadly lightning strikes.

As the storm charges eastward at midweek, the bulk of the wet and windy weather will shift into the Northeast.

A few showers will dampen the Southern states during the first part of Wednesday before quickly diminishing by the evening.

Thanksgiving Day is forecast to be quieter overall across the South, but a new storm is poised to spread rain, snow and even a bit of ice back across the Plains on the holiday.

Spanning Friday to Saturday, there may be another round of heavy, gusty and locally severe storms from parts of Texas and the southern Plains to the lower Mississippi Valley.
