The episode as NWS TSA wrote it up.
Severe thunderstorms developed along a dry line over central and western Oklahoma during the afternoon of the 1st, as a strong upper level disturbance translated into the Southern Plains. The storms moved through eastern Oklahoma during the late afternoon and evening hours. Moderately strong instability combined with strong deep layer shear to support the development of some supercell thunderstorms, which produced several tornadoes, and damaging wind gusts. The storms evolved into a squall line that also produced damaging wind gusts during the late evening.

Area Forecast Discussion National Weather Service Tulsa OK 220 PM CDT Mon Apr 1 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (The rest of this afternoon ) Issued at 156 PM CDT Mon Apr 1 2024 The main weather concern today is the impending severe weather threat that will be ramping up for the remainder of this afternoon and evening. Key Messages: 1.) There is an moderate risk (45% chance within 25 miles of a point) of severe weather across the area today. 2.) The severe hazard most likely to occur is large to very large hail (45% chance). Tornadoes (10% chance) and damaging wind (30% chance) may also occur. 3.) Severe storms will most likely occur in the mid afternoon to early evening in northeast OK, and in the mid to late evening in southeast OK and northwest AR. Details: A broad (but positively tilted) trough across the Desert Southwest and associated upper level jet are impinging on the region and promoting broad lift. This will gradually lower surface pressure along the cold front, with low level warm and moist advection continuing east of the front. In the near term, a stout elevated mix layer is currently keeping instability capped, but there are signs of this changing. Recent ACARS profiles have shown the ML to be deepening, eroding the cap from underneath. Additionally radar/satellite have shown CI further west across central OK. As we progress through the afternoon and evening, synoptic scale lift beneath the upper level jet streak and eventually mesoscale lift ahead of the cold front is expected to break this cap and allow for convective initiation within the forecast area. As far as timing, the initial storm activity will occur in northeast OK as rather modest low level shear coupled with steep lapse rates promotes a risk of large to very large hail. This will occur as initially discrete cells fire near the dry line. There will also be a threat of isolated tornadoes and damaging wind gusts. To account for these threats a Tornado Watch was recently issued for portions of eastern OK. As we head deeper into the afternoon, long and straight hodographs will promote splitting supercells that will eventually merge into more of a QLCS feature. The low level jet will punch out the lower level wind fields a bit more near sunset, relatively increasing the tornado threat for areas east of the dry line at that time. It's worth mentioning that although widespread flooding does not appear to be in play, some localized minor flooding could occur with any training or particularly heavy storms. The cold front will push into northeast OK in the late evening, gradually moving southeast overnight, ending the severe weather threat. Gusty northerly winds and much cooler air will follow behind the cold front. && .LONG TERM... (Tonight through Monday) Issued at 156 PM CDT Mon Apr 1 2024 Tuesday will be cloudy and drizzly/showery in spots as much cooler air spills in behind the cold front. High temperatures will only reach the mid 50s to low 60s for most areas, coolest in the northwest. Skies are expected to clear out into Wednesday morning, with low temperatures falling into the mid 30s to low 40s. A few of the most cold-prone spots could see a light frost. The deep low pressure responsible for this cooler weather will gradually move east through mid week with higher pressure building in from the west. High temperatures will gradually warm, with highs in the 60s Wed-Thu and 70s Fri-Sun. Meanwhile, as the next weather system deepens in the west, breezy southerly winds will develop by late in the week. This will once again increase the fire weather potential across the area. As this system approach the area next Saturday-Sunday, rain chances will increase once again. The solar eclipse of April 8th may be impacted by this weather system or another one that is set to affect the area around next Tuesday. Ensemble cluster analysis does not shed much light on the subject at this time, with models split roughly 50- 50 into two camps for relatively better or worse viewing conditions. && .AVIATION... (18Z TAFS) Issued at 1236 PM CDT Mon Apr 1 2024 Thunderstorms will be the main impact to flight conditions through this afternoon and evening. Scattered to numerous strong to severe thunderstorms are expected to track across eastern Oklahoma and western Arkansas beginning mid afternoon through the evening hours. Reduced visibility and strong gusty winds will accompany any storms that affect terminals. A cold front will move through later tonight bringing a shift to westerly and then northwesterly winds across all sites through tomorrow morning. Low clouds will funnel back in behind the boundary tomorrow morning with MVFR conditions likely and possibly some scattered IFR conditions, especially across northeast Oklahoma sites.

AREA...Eastern Oklahoma and Western Arkansas. ONSET...Ongoing. DISCUSSION... Severe thunderstorms are expected from late this afternoon through much of the evening. The primary threat will be very large hail up to tennis ball size, and damaging wind gusts up to 70 mph. There is also a conditional threat of a few tornadoes during the early evening. The primary severe weather threat will evolve as a cold front and dry line approach eastern Oklahoma. Thunderstorms are expected to develop across eastern Oklahoma between 3 and 6 pm and quickly become severe, with potential for very large or damaging hail. Storms are expected to increase and spread eastward through the evening with a continued threat of very large hail, and an increasing damaging wind threat as storms grow upscale. Low level winds are expected to strengthen near sunset, which may increase the tornado potential some for part of the evening. Most of the storms will exit the area around midnight. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Activation of the Regional Spotter Network Expected. Severe weather watches and warnings will likely be issued for much of eastern Oklahoma and western Arkansas. Forecast details regarding the location of highest severe weather threats will continue to evolve throughout the day today. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday. TUESDAY AND WEDNESDAY...High Wind Potential. THURSDAY AND FRIDAY...No Hazards. SATURDAY AND SUNDAY...Thunderstorm and High Wind Potential. EXTENDED DISCUSSION... Breezy and cooler conditions will occur behind the system Tuesday and Wednesday.
