| Episode Narrative | The storm environment for May 20th involved a very unstable atmosphere, especially across the northern third of Northeast Texas, Southeast Oklahoma and Southwest Arkansas. The atmosphere was weakly capped which resulted in the development of scattered severe thunderstorms across the region. An upper level disturbance moved across the region as well and with cold temperatures aloft resulting in steep mid level lapse rates...a majority of the storms produced large hail. High shear was also in place in the mid and lower levels of the atmosphere which provided a wind threat as well. Some of these storms produced tornadoes across the region. |
| Event Narrative | The National Weather Service conducted a storm survey in Red River County and concluded that damage was the result of an EF0 tornado. The tornado first touched down over a wooded area east of Manchester damaging a few trees. The tornado moved northeast crossing FM 195 where a few small trees were snapped and a few small trees and limbs. The tornado ended north of FM 195. The Maximum winds are estimated at 65-70 mph. |
