Thunderstorm Wind in Red River Parish, Louisiana

A tree was blown down near the intersection of Highways 371 and 786.

A weak cold front extended from Eastern Oklahoma into Northeast Texas during the late evening into the early morning hours of January 9th-10th, and separated a warm, moist, and unstable air mass to its east, with a slightly cooler but drier air mass to the west. A surface low developed during the evening and overnight hours along the frontal boundary, enhancing a deep southerly low level flow into East Texas and North Louisiana, with a longwave trough shifting east through the Rockies into the Southern Plains enhancing large scale forcing along and ahead of the front across the warm sector. Thus, scattered to numerous showers and thunderstorms developed across this area, and spread east across East Texas and North Louisiana during the evening through the overnight hours. These storms tapped better low level wind shear as they entered Northwest Louisiana, which resulted in isolated severe thunderstorms that developed and even spawned a tornado just southeast of Coushatta. These storms weakened as they shifted farther east into Northcentral Louisiana during the early morning hours of the 10th.
