As a strong shortwave trough dove into the region late in the evening of June 19th and into the early morning hours of June 20th, a line of severe storms tore across the Highway 82 corridor. The strongest of the wind occurred in southeast Arkansas and the Mississippi Delta, where 80 to 90 mph winds caused extensive damage.

The episode as NWS JAN wrote it up.
As a strong shortwave trough dove into the region late in the evening of June 19th and into the early morning hours of June 20th, a line of severe storms tore across the Highway 82 corridor. The strongest of the wind occurred in southeast Arkansas and the Mississippi Delta, where 80 to 90 mph winds caused extensive damage. As the line tracked to the east, some wind damage occurred but the winds were not as strong through this area.

Area Forecast Discussion...UPDATED National Weather Service Jackson MS 921 PM CDT Wed Jun 19 2019 ...SEVERE STORMS POSSIBLE TONIGHT... .UPDATE... Updated for evening discussion. && .DISCUSSION... Rest of tonight: Overall forecast is generally playing out on track, with a MCS diving down through southern Arkansas, in the west-northwest flow. Strong shortwave trough is diving down across the ArkLaTex, leading to severe convection development propagating towards the region. Severe thoughts are generally playing out on track, as juxtaposition of strong mid-deep layer effective bulk shear & some lingering instability (i.e. 35-45kts & 1500-3000 J/kg MLCAPE) lead to a favorable parameter space for severe convection. Some severe storms will continue to propagate to the east-southeast through southeast Arkansas, northeast Louisiana and somewhat east of the Mississippi River into the ArkLaMiss Delta. The south & eastward extent of these storms becomes more in question as it moves into somewhat less destabilized & suppressed environment from storms this morning & some mixing occurred into the afternoon. Main adjustments were a collaborated severe thunderstorm watch over southeast Arkansas, northeast Louisiana & northwest Delta through 4AM. Main threats remain damaging wind gusts & large hail. An isolated tornado or two can't be ruled out, especially in any eastward bowing segments due to ~25kt 0-3km shear vectors from west-northwest. No changes were needed to the HWO/graphics but eastward severe extent may become a question mark into the night & might be less of a threat further east, especially east of the I-55 corridor. /DC/ Prior discussion below: Tonight and Thursday: The outflow boundary from a decaying MCS moved across our CWA earlier today and has scoured out our rain chances with the exception of very low chances of a storm or two this afternoon into the early evening over east Mississippi. Rain chances will increase this evening though especially for the northern half of our CWA. Regional satellite imagery and radar showed storms firing over the Southern Plains. A shortwave trough will move over the Plains and enhance develop of the storms that are expected to form another MCS as it approaches our CWA. The environment is expected to become more favorable for severe storm development over our CWA as the MCS enters later this evening. Considering the expected parameters, damaging wind gusts and hail larger than quarter size will be the main threats but a tornado or two cannot be ruled out. Brief heavy downpours will also accompany the activity. Model timing and track of the convection still differ but consensus suggests that an MCS will move into the northwestern portions of our CWA by 10 pm and continue to spread east across our CWA through the night. There remains some question as to how far south the severe threat will get before the convection weakens but the threat for severe storms is expected to end before sunrise Thursday. The shortwave will be east of Mississippi Thursday but a moist airmass will be left over our CWA. A potential boundary left over from the MCS along our southern zones may become the focus for a strong storm or two Thursday afternoon. In addition, dew points in the low to mid 70s lingering over our southwest with temperatures in the lower 90s will lead to heat index values near 105F Thursday afternoon. Wl maintain mention of this in the HWO. /22/ Thursday night through next week: A few storms will likely linger into Thursday night as the shortwave trough passes to the east and leaves behind a weak surface boundary, but confidence is low on where these would focus and just how much coverage there will be given the uncertainties with convective evolution for Thursday and diminishing synoptic scale support. Showers and thunderstorms cannot be entirely ruled out for Friday, especially if returning southerly flow can help any seabreeze convection to spread northward. Then it looks like the next best chance for more than a few isolated showers or storms will be next Monday into Tuesday time frame as a low pressure system moving eastward across the country brings some height falls and increases convection at least to our north and west. For now it appears the associated frontal boundary will stall out before dipping into our forecast area, but we will continue to monitor the trends for this early week setup. Heat stress will continue to be a concern over mainly western/ southern portions of the ArkLaMiss as dewpoints remain in the low to mid 70s throughout the day while temperatures climb into the low 90s resulting in heat index values in the 103 to 105 degree range. The limited heat threat continues in the HWO/graphics for heat indices reaching 105, and we will continue to monitor for now the possibility of heat advisory issuance. /NF/EC/ && .AVIATION... 00Z TAF discussion: VFR conditions will prevail this evening. Guidance continues to suggest a line of showers and storms moving through after 03-06Z. It is unclear as to how far south and east it will progress, but should at least affect Delta TAF sites. Amendments likely as situation evolved through the evening and night. MVFR ceilings possible after 11Z tomorrow, resuming VFR by mid morning. /28/ && .PRELIMINARY POINT TEMPS/POPS...

A tree was blown down on Highway 72 north of Hamburg.
A swath of 70-80 mph winds impacted far north Chicot County, which included the city of Dermott and areas along Highways 35 and 65, and into Halley. Much of this was uprooted, snapped, or damaged trees. There were also trees blown down on some homes and power lines. There was quite a bit of minor roof damage to structures from the wind. Pockets of corn stalks were also bent or laid down. Power poles were snapped.
A few trees were blown down and many large limbs were broken off.
