		Brief Description: EVENT NARRATIVE: Most of the tornado damage was north of interstate 30 with some structures showing EF2 damage. In particular, the cinderblock and brick lawnmower business just north of Hwy 82 was completely destroyed with roofing debris and lawnmower parts thrown to the west and north of the building location. A brick home several hundred yards from the lawnmower business sustained significant damage to its roof and exterior walls. A metal shop building built with large metal I-beams was completely destroyed. I-beams were twisted and thrown in a northerly and westerly direction up to 200 yards from the building location with concrete still attached. The trees between the large metal building and the interstate were uprooted or snapped in a convergent pattern...indicative of tornadic winds. In total...12 structures were damaged or destroyed between Hwy 82 and the interstate and numerous trees were downed. Three tractor trailers were flipped on interstate 30 which resulted in the interstate being shut down and there was one injury. Further south of Hwy 82 on the Lonestar Army Ammunition Depot, numerous trees were snapped or uprooted and damage to parts of the Depot were reported...although it was not surveyed. North of interstate 30 along the service road...an outbuilding sales business lost several buildings and had many others damaged. Along Farm to Market 2253, numerous trees were snapped and uprooted on either side of the road and several sheds and barns were damaged or destroyed. A greenhouse was severely damaged near the end of the track. Some homes were also damaged from fallen trees. EPISODE NARRATIVE: A strong pressure gradient initially across northeast Texas and northwest Louisiana during the pre dawn hours of April 10th produced non-thunderstorm wind gusts responsible for downing trees and power lines. Later that morning...a squall line entered northeast Texas and southeast Oklahoma producing mostly wind damage along with some large hail and an isolated tornado in Bowie County Texas.

		Brief Description: EVENT NARRATIVE: This tornado initially touched down in southwestern Miller County, Arkansas along CR 80...snapping several pine trees about 2 miles south of Ravana. The tornado then moved toward the intersection of CR 31 and CR 32. Here, at its widest and strongest, the tornado uprooted and snapped numerous pine and oak trees, some 2 to 3 feet in diameter. The storm completely destroyed an outbuilding and mobile home, placing roofing material in a tree approximately a half mile away. Mostly EF1 damage was noted elsewhere as the tornado continued moving east-northeast across southern Miller County. Numerous pine and oak trees were either snapped or uprooted, with pieces of roofing material ripped from well-constructed homes. The tornado passed near the intersection of US-71 and AR-549, near the community of Doddridge, before lifting approximately 2.5 miles north-northeast of Kiblah AR. EPISODE NARRATIVE: A strong upper level storm system along with a surface dry line/front over northeast Texas moved east during the evening hours of April 9th into the early morning hours of April 10th causing long lived supercell thunderstorms. These thunderstorms caused long track tornadoes to occur across southeast Oklahoma, southwest Arkansas, northeast Texas, and north Louisiana.

		Brief Description: The tornado first touched down 2 1/2 miles south-southwest of Okolona. It first moved in an easterly direction, passing near the town of Center Point and across several county roads where a total of 17 homes and 3 outbuildings were either damaged or destroyed. A large amount of trees and power lines were also downed. The storm then travelled more in an east-northeast direction, touching down intermittently. A large amount of timber was blown down in the eastern part of the county several miles southeast of Griffithtown. The storm moved out of Clark County at around 315 pm CDT. No injuries were reported along the track of the tornado. Initial estimates place the amount of damage at around $1,800,000, with $1,300,000 of that in timber damage alone.

		Brief Description: EVENT NARRATIVE: This tornado initially touched down near an open field, approximately 1.5 mile south of Centerpoint, along Coonridge Road. Travelling slightly east of due north, the tornado snapped and uprooted numerous pine and oak trees. The most significant damage occurred at a single-family residence 0.75 mile north of the touchdown, where the house suffered a considerable amount of damage. The garage, roof, and many supporting walls were removed from the foundation. All windows not completely blown out by the storm were still shattered. A barn adjacent to the house had a considerable loss of roofing material but, although shifted off its foundation, remained largely intact. Trees and powerlines were snapped or uprooted as the storm moved through the community of Centerpoint before lifting along Billings Road, about 0.25 mile east of SR-4. There was one injury at the residence but the injury was not life threatening. The Arkansas governor declared Howard County a disaster area because of the tornado damage in the county. EPISODE NARRATIVE: A strong upper level storm system along with a surface dry line/front over northeast Texas moved east during the evening hours of April 9th into the early morning hours of April 10th causing long lived supercell thunderstorms. These thunderstorms caused long track tornadoes to occur across southeast Oklahoma, southwest Arkansas, northeast Texas, and north Louisiana.

		Brief Description: The tornado moved out of Nevada County and into Clark County approximately 6.5 miles south of Okolona at 220 pm CST.

A number of homes and businesses in Arkadelphia were either damaged or destroyed. 5 people in Arkadelphia were also killed. The tornado continued to move northeastward, knocking down more trees and power lines, as well as damaging more homes.

		Brief Description: EVENT NARRATIVE: The tornado caused a massive tree blowdown soon after touching down. It then passed west of Velie and near Amy. One house had part of one wall and a portion of its roof torn off, part of the roof was torn off a mobile home, another mobile home was blown off its foundation, and several outbuildings were damaged. The tornado exited Ouachita County about 3 1/3 miles east-northeast of Smead and continued into Dallas County about 3 2/3 miles west-southwest of Holly Springs. EPISODE NARRATIVE: A large storm system in the Rockies headed through the Plains into the upper Midwest on the 29th. Rain increased ahead of the system, and became widespread in Arkansas. Meanwhile, a cold front arrived from the west. Because the system was so far to the north, it did not give the front much push. The front slowed down, which prolonged the rain. The result was widespread flash flooding, which gave way to areal flooding and river flooding. Winds changed direction and speed up through the atmosphere, a favorable condition for tornadoes. However, instability was sufficient only in southern Arkansas for the development of tornadoes.

		Brief Description: EVENT NARRATIVE: An EF2 tornado touched down in Dierks, Arkansas destroying a laundrymat and damaging numerous homes and businesses. Numerous trees were snapped or uprooted along the track which started on the southwest side of town where a storage building was destroyed. The tornado crossed the town downing trees and powerlines. Shingles were torn off of numerous homes within the town. The tornado continued northeast and ripped a 100 ft section of roof off of a chicken house. The tornado lifted northeast of the chicken house. Maximum winds are estimated at 105-115 mph. EPISODE NARRATIVE: A very unstable airmass developed across much of the Southern Plains and Lower Mississippi Valley during the afternoon and evening hours of April 30th. A strong upper level trough moved into the Southern Plains during the afternoon and sparked strong to severe thunderstorms across much of southeast Oklahoma into northeast Texas and southwest Arkansas. Strong deep layer shear and low level directional shear was present during the evening and this resulted in storms developing supercellular characteristics. Large hail and isolated tornadoes developed with this activity across the region.
