Thunderstorm Wind in Winn Parish, Louisiana

Trees were blown down near Highway 167 and Pacton-Alexandria Road.

Showers and thunderstorms, some of which contained heavy rainfall, continued from the evening hours on April 30th through the early morning hours of May 1st, along and ahead of a weak cold front that slowly advanced southeast into portions of East Texas and Southern Arkansas. Widespread rainfall amounts of 2-5+ inches fell from April 30th through the early morning hours of May 1st generally along the I-20 corridor of East Texas and North Louisiana, resulting in continued instances of flash flooding especially across the Shreveport/Bossier City areas, before the flood threat subsided prior to daybreak. Additional isolated severe thunderstorms did manage to develop though farther south during the early morning hours across Winn and Grant Parishes, producing damaging winds before weakening shortly thereafter. The weak surface boundary lingered across portions of Lower East Texas south of I-20 into Northwest Louisiana to along the Louisiana/Arkansas border through the afternoon of the 1st, with very warm, moist, and unstable conditions again developing along and south of the front. The unstable air mass along and southeast of the front coupled with weak forcing aloft contributed to the development of a few isolated supercell thunderstorms over portions of Deep East Texas into Northwest Louisiana during the late afternoon and early evening, with these storms producing multiple instances of large hail before weakening.
