Episode Narrative A strong upper level trough shifted east across Northern Mexico and into the Big Bend area of Southwest Texas during the early morning hours of April 2nd, before lifting northeast into North Texas during the afternoon. Meanwhile, an deepening surface low over North Texas allowed for warm, moist, and unstable air to stream north across East Texas and North Louisiana just south of a warm front as it stalled near the Interstate 20 corridor. Very strong wind shear and steepening lapse rates ahead of the ejecting upper level trough resulted in strong deep layer forcing for widespread strong to severe thunderstorms across East Texas south of Interstate 20, as well as much of Northcentral Louisiana. Numerous reports of wind damage and a few large hail reports were received across these areas, with several tornadoes (some strong) also having touched down across portions of Deep East Texas, Western and Central Louisiana. The majority of these tornado touchdowns were focused across Grant, Winn, Caldwell, and LaSalle Parishes, resulting in numerous snapped/uprooted trees, and damage to multiple homes across these areas. Fortunately, no injuries or fatalities occurred from these tornadoes.
Event Narrative An EF-1 tornado with maximum estimated winds between 100-110 mph touched down in the Kisatchie National Forest just south of Highway 500 in Northern Grant Parish, snapping and uprooting numerous trees. This tornado tracked northeast across Parish Road 610 before crossing over into Winn Parish.
