The episode as NWS SHV wrote it up.
Scattered strong to severe thunderstorms extended from Southeast Oklahoma down across Central Texas late in the evening on March 10th, with the most organized threat area over Northeast Texas into Southeast Oklahoma and Southwest Arkansas. Effective storm-relative helicity ahead of the prominent line of thunderstorms was quite favorable for low-level rotation, and instability was rather strong as well. The VAD wind profile from the Shreveport Doppler Radar indicated a very favorable hodograph for rotating storms with 0-1 km storm-relative helicity over 250 m2/s2. As a result, severe thunderstorms produced an isolated tornado and some damaging wind gusts in parts of McCurtain County just prior to midnight on March 10th.

NWS Shreveport, LA wrote its last area forecast discussion before the first event at Mar 10, 10:14 PM CST, 1 hour 11 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Shreveport LA 1114 PM CDT Tue Mar 10 2026 ...New AVIATION... .KEY MESSAGES... Issued at 126 PM CDT Tue Mar 10 2026 - Multiple rounds of strong to severe thunderstorms will impact the ArkLaTex, first along and north of I-30 overnight tonight, with large hail, tornadoes and wind gusts all possible. - Further strong to severe thunderstorms are possible during the day tomorrow, bringing tornadoes, damaging wind gusts and hail to areas along and south of I-30. - Quiet conditions will close out this week, followed by a warming trend into the weekend and a cold front bringing a sharp cool down to start next week. && .DISCUSSION... Issued at 126 PM CDT Tue Mar 10 2026 The closed low over northern Mexico will open up into a trough as it pushes inland through this evening, advancing across central Texas and potentially reforming a new cutoff low during the day tomorrow, finally passing over Louisiana overnight into Thursday. This will, as previously advertised, be the catalyst for multiple rounds of showers and thunderstorms across the ArkLaTex over the next 36-48 hours. The latest high resolution guidance continues to depict the clusters of showers across east Texas moving northeast into this evening, with some areas of stronger convective development possible. The first main event, meanwhile, will be taking shape as a potent squall line over central Texas which will push east this evening, bringing strong to severe thunderstorms to areas along and north of the I-30 corridor. It bears mentioning that model guidance has been inconsistent regarding how long this line will hold together as it pushes east, with the NAM 3km largely collapsing by the time it reaches us, and the HRRR hinting at a chance of more robust convection holding together into Oklahoma and southern Arkansas. The second half of the main event will be stirred up as the closed low itself pushes into the ArkLaTex during the daytime hours tomorrow, with distinct lines of storms aligned with the surface warm and cold front boundaries. Impacts look to begins from the southwest by midday, continuing through the evening and overnight hours, with rainfall concluding by daybreak Thursday. The big question mark surrounding severe activity with this second wave hinges on the position of the closed low, and particularly its associated warm sector. If the low takes a more northerly track, more of the ArkLaTex will be in the warm sector and thus at risk. By contrast, a southerly track could see the ArkLaTex mostly if not entirely cut off from the environment favorable for severe weather. At this time, zones along and south of the I-30 corridor would do well to be prepared for all modes of severe weather, including tornadoes, damaging wind gusts, and large hail. Under clearing skies with northwest flow aloft in the wake of the frontal passage, highs Thursday afternoon will only reach the middle to upper 60s, followed by morning lows in the upper 30s north to lower 40s south Friday morning. The weekend will see further warming under pseudo-zonal flow aloft reinforced by southerly surface flow, as 70s and lower 80s make their return before a deep trough and potent cold front bring a slight chance of showers late Sunday overnight into Monday, as well as a marked cooldown featuring widespread lows in the 30s and even a few northerly sites possibly getting down to freezing early next week to close out this extended forecast period. /26/ && .AVIATION... (06Z TAFS) Issued at 1108 PM CDT Tue Mar 10 2026 Very busy Aviation TAF period as a longwave trough will eject out into Southern Plains and Lower Miss Valley bringing with it scattered to numerous showers and thunderstorms with some of these storms likely severe. Currently watching a broken line of convection across N TX/S OK that will be moving into our northwest airspace over the next 3-4 hours or so. Have accounted for this at the TYR/TYR/GGG/SHV and ELD airports through sunrise this morning. As we transition into the late morning and afternoon hours, a new line of convection is forecast to develop across the I-20 Corridor of NE TX and rapidly expand east and northeast, encompassing the eastern half and southern half of our airspace through the late evening hours before all convection moves east of our airspace. Have accounted for this for all terminals. Prefrontal pressure gradient is very strong this morning through the afternoon outside of convection of course and post frontal pressure gradient is very strong as well with winds quickly shifting around to the north with sustained wind speeds near 15kts with gusts upwards of 30kts this evening across our entire airspace. 13 && .SPOTTER INFORMATION STATEMENT...

2 thunderstorm wind, 1 tornado. Local standard time, as filed.
The roof was partially peeled back on a home near Garvin.
A camper RV was flipped with occupants inside in the Holly Creek area between Garvin and Broken Bow along with a few homes damaged in the area. No injuries were reported.
A line of severe thunderstorms moved into McCurtain County, Oklahoma, late in the evening on March 10th. Circulations were embedded within this line of thunderstorms, with one of which producing an EF2 tornado with estimated maximum winds near 118 mph that began on Old Golden Highway, resulting in snapped trees and the loss of shingles to a local residence. The tornado then continued east, reaching Thomas Road near the intersection of Old Golden Highway where more trees were snapped and uprooted and a barn/shed experienced damage to the roof. The tornado then began to pick up in intensity as it moved across Oak Hill Road where numerous trees were snapped and uprooted. As the tornado then continued northeast towards Rhoden Road, it caused significant damage to a family residence, resulting in the collapse of most exterior walls and an injury to the occupant who had to be airlifted to the hospital. Trees were then uprooted and fell onto this residence, causing additional damage. Next door to this home, significant damage was found to other structures as well as additional tree damage. Just before reaching Rhoden Road, another residence was damaged, where areas of the roof were uplifted, multiple trees were snapped and uprooted, and the neighboring barn experienced significant roof damage. The tornado then moved north/northeast of the road, pushing a small outbuilding off of its foundation and snapping and uprooting more trees before lifting as it crossed Highway 3.
