The episode as NWS SHV wrote it up.
A weak cool front drifted south into portions of North Texas, extreme Southeast Oklahoma, and Western Arkansas during the late afternoon through the evening hours on June 11th. Weak perturbations in the northwest flow aloft enhanced large scale forcing aloft near the front, with surface convergence within a very unstable air mass along the boundary contributing to the development of widely scattered severe thunderstorms across Red River County Texas into Southern McCurtain County Oklahoma and Little River County Arkansas. These storms produced large hail over Southern McCurtain County, and damaging winds which downed a power line in Bogata in Southwest Red River County before weakening by midnight.

Area Forecast Discussion National Weather Service Shreveport LA 718 PM CDT Sun Jun 11 2023 ...New AVIATION... .SHORT TERM... (This evening through Monday Night) Issued at 250 PM CDT Sun Jun 11 2023 Potentially, another round for severe weather across the region tonight and again tomorrow. So far today, upper ridging has kept the region dry. But, we have already started to see some development just north of the CWA across Eastern Oklahoma, which resulted in a severe thunderstorm warning. This was a little unexpected, but probably the start of things to come. Additional isolated convection is expected to develop across North Texas by the early evening hours and across portions of Eastern Arkansas/Northern Mississippi. The north Texas convection may move into portions of East Texas before midnight, with the Eastern Arkansas convection possibly moving into our Ark-La-Miss zones around the same time. However, I believe there could be some additional isolated convection north of I-20 overnight along the cool front as it slowly pushes into the region. With plenty of instability across the region the Storm Prediction Center has highlighted a Slight Risk for damaging winds and/or hail, generally along and north of the Interstate 20 corridor. By tomorrow, models are suggesting more widespread convection, as the aforementioned frontal boundary will stall as it bisects the region. Again, plenty of instability will be in place, so more isolated severe weather is a possibility. The greatest threat will remain damaging winds and/or large hail. But, with lots of low- level moisture available and training of cells along the boundary, flash flooding could become a concern. /20/ && .LONG TERM... (Tuesday through next Saturday) Issued at 250 PM CDT Sun Jun 11 2023 An unsettled pattern will continue across our portion of the country, at least through Wednesday with thunderstorms chances, some of which could be strong to severe. The setup for this unsettled pattern is the same one we've been dealing with for close to two weeks. An anchored, closed upper level trough across the Great Lakes into New England with a flat ridge across Mexico and into portions of the Tx Hill Country. This pattern continues to favor west northwest flow aloft across the Middle Red River Valley which means subtle disturbances embedded in this flow will encounter either diurnal heating during the day, or will be fed by a nocturnal, low level jet at night with the end result being scattered strong to severe thunderstorms Tuesday and again possibly on Wednesday. SPC has outlooked a Slight Risk for severe weather across nearly our entire region Tuesday/Tuesday Night and given the above mentioned flow this is certainly possible. In addition, the latest progs are showing a disturbance moving out of the Lee of the Rockies and into the Southern Plains late Wed/Wed Night with perhaps another threat of strong to severe thunderstorms late in the day 4 period. These thunderstorms chances through at least Wed will help to temper temperatures somewhat, especially across our northern half. By Thu into Fri...we begin to see upper ridging trying to build from the south and west and as this occurs, precipitation chances become less and less and temperatures should start to climb. For the past several days, the NBM has appeared to show a warm bias with temperatures for late this week into next weekend as heights and thickness values do not quite support widespread triple digit heat. For that reason, have continued the trend of undercutting NBM Max temps a few degrees beginning Thu and continuing through the upcoming weekend. What models are in agreement with is the above mentioned ridge will continue building north and east into our region and just beyond the 7 day forecast period, the upper ridge will likely be anchored across the Southern Plains/Lower Miss Valley and the triple digit heat will likely be here for sure by then. 13 && .AVIATION... (00Z TAFS) Issued at 701 PM CDT Sun Jun 11 2023 For the ArkLaTex terminals, VFR this eve, but TS expected 03-09Z w/ a little midlvl disturbance. Already firing TS S of KDAL/KRBD and movg E. Will amend our VCTS sites w/ tempo groups for an hr/two as we go. Otherwise, this may be all we see this cycle. Look for IFR/MVFR 09-13Z cigs/vsby issues around daybreak. Then VFR w/ varying winds across the area. SW winds will slack and veer around to N/NE overnight behind impulse, & keep NE 5-15KT for Mon. Lots more TS this week aftn/eve esp, but some nocturnal. /24/ && .PRELIMINARY POINT TEMPS/POPS...

Another chance for strong to severe thunderstorms will return by this evening and overnight as a frontal boundary shifts southward into the region. Damaging wind gusts will be the primary threat in addition to large hail also being possible with some of the most intense storms. .DAYS TWO THROUGH SEVEN...Monday through Saturday. The potential for strong to severe thunderstorms will persist through the middle of the upcoming week as a frontal boundary is expected to stall and linger across the region. In addition, small disturbances in the upper-level northwest flow pattern will combine with the front to further enhance thunderstorm chances. As a result, damaging wind gusts and large hail will remain possible each day as thunderstorms increase. By late week, the chance of thunderstorms will decrease while temperatures increase into the mid to even upper 90s with heat advisory conditions possible. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed by this evening and overnight. 19
