The episode as NWS OUN wrote it up.
Broad southwesterly mid-level flow prevailed across the Southern Plains on the 8th. Widespread thunderstorm development occurred in the vicinity of a quasi-stationary boundary across west-central into north-central Texas during the evening hours. A few storms encroached on far southern portions of the WFO Norman Forecast Area, with a few instances of large hail and a downburst wind event occurring across portions of the Red River Valley.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Norman, OK wrote its last area forecast discussion before the first event at Apr 8, 4:46 PM CST, 3 hours 44 minutes earlier.
Area Forecast Discussion National Weather Service Norman OK 546 PM CDT Mon Apr 8 2024 ...New AVIATION... .SHORT TERM... (This evening through Tuesday) Issued at 322 PM CDT Mon Apr 8 2024 An approaching lead shortwave trough will interact with northward advancing warm front and increasing low level moisture to create a increasingly favorable environment for convective development by late today. Initial development is anticipated near and ahead of a dryline and surface low over west Texas. This should be southwest of our western north Texas counties, somewhere south or southeast of Lubbock around 5 or 6 pm. This activity will be in an environment conducive to initially produce supercell thunderstorms capable of very large hail. The lack of richer low level moisture looks to keep any tornado risk confined to mainly near and south of the Red river during the early/mid evening time frame. Soundings would suggest even a bit of a inverted V looks indicating some wind risk as well. This activity will move east and northeast into western north Texas and southwest Oklahoma during the evening hours. As it move north the activity will likely become elevated in nature and limited instability will limit northward extent of severe storms. Stronger storms look to remain near the Red river and points south. The main upper low will continue to approach the area on Tuesday with continuing rain chances, especially across the south. The abundant cloud cover and precipitation will limit instability and overall severe risk, but may see sufficient instability by late in the day along the Red river for a few low end severe storms. Main impacts may be rainfall as some locations may see an inch or two by the end of the day tomorrow. Some of the models are also hinting as descent rain chances and amounts across parts of western/northwestern by late tomorrow and tomorrow night. && .LONG TERM... (Tuesday night through next Sunday) Issued at 322 PM CDT Mon Apr 8 2024 Rain chances continue Wednesday as the upper low translates east across north Texas. Another round of heavier rainfall will also be possible across southern Oklahoma and north Texas. Limited instability will preclude in additional severe risk. However, if these bands of heavier rainfall end up moving through some of the same areas, some localized flooding might be possible. The cloud cover and associated precip, as well as colder air filtering south in the wake of the aforementioned cold front, temperatures will be a bit cooler as well Wednesday and even into the day Thursday. Although the precip should end Wednesday night from west to east. Mid-level ridging then builds across the Rockies out into the Plains as we go into the latter part of the week and the weekend. This will result in another warming trend with much of the area back in the 80s by Sunday. Next chance of rain/storms comes back into the forecast early next week. && .AVIATION... (00Z TAFS) Issued at 542 PM CDT Mon Apr 8 2024 A frontal boundary moved through all but KDUA TAF site so sites north of the front will have winds from the N to NE while KDUA is expected to have a SE to E wind. Storms are expected to move across portions of the area this evening/overnight with another wave of showers/storms moving in early Tuesday then moving across the area. The highest chances for showers/storms will be across southern OK and north TX. VFR and MVFR ceilings are expected this TAF period. && .PRELIMINARY POINT TEMPS/POPS...
