The episode as NWS OUN wrote it up.
Thunderstorms developed by late afternoon of the 22nd across southwestern Oklahoma and western-north Texas. This activity was initiated near convective outflow boundaries from prior thunderstorms and enhanced by strong surface heating. The resulting environment featured strong instability, steep lapse rates, and favorable deep-layer wind shear for organized thunderstorms. Multiple splitting supercell thunderstorms emerged in this regime, producing widespread reports of large to very large hail during the evening.
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 May 22, 1:16 PM CST, 1 hour 38 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Norman OK 216 PM CDT Thu May 22 2025 ...New NEAR TERM, SHORT TERM... .KEY MESSAGES... Updated at 155 PM CDT Thu May 22 2025 - Thunderstorm chances continue into the holiday weekend with a chance of severe storms each day - Heavy rainfall and flooding may occur especially with a cold front Saturday night into Sunday - Cooler temperatures are possible behind a front early next week. && .NEAR TERM... (Rest of today and tonight) Issued at 155 PM CDT Thu May 22 2025 The strongest part of our early morning convection continues to move slowly southward into northern Texas/far southern Oklahoma. An associated outflow boundary extends from near Binger southward to Lawton and then southeastward into northern Texas. Ahead of the outflow, better moisture return is occurring into the DFW area where upper 60 to lower 70 dewpoint temperatures reside. Farther west, surface temperatures are warmer with slightly lower dewpoint air. As strong heating continues, it is likely that additional severe storms will form across parts of southwest Oklahoma and western north Texas. With the ongoing convection in southern Oklahoma and cloud cover, additional severe convection this afternoon should stay south of the Red River in Texas (eastern part of the outflow boundary). Despite some weakness in the mid level flow, good direction turning and high instability will support the risk of very large hail and damaging wind gusts. Any storm that can become establish and move along the outflow boundary will have the potential to produce a tornado or two. Most of the convection this afternoon and early evening should be south of our area by mid evening. Most areas will remain dry from the mid evening into the overnight hours, with increasing chances of elevated storms around sunrise Friday. && .SHORT TERM... (Friday through Saturday night) Issued at 155 PM CDT Thu May 22 2025 A much stronger low-level jet is expected to focus elevated thunderstorms by early Friday morning (6-8 am). Currently, it appears north central and central Oklahoma will be the favored areas of seeing this development. Elevated instability is progged to be around 1500+ J/kg, so strong to severe thunderstorms appear likely. The mid and upper level flow will generally move storms to the east and southeast around 30-35 mph. It's certainly possible the majority of the storms will move east of the area by early afternoon with a lull in rain and storm chances through the late afternoon/early evening. A surface low is expected to deepen during the day across southeast Oklahoma. With a 10 mb gradient across the main body of Oklahoma and mixing, breezy southerly winds can be anticipated. A few storms may develop across a dryline in the central/eastern Texas Panhandle which may drift into far western Oklahoma/western north Texas by early/mid evening. Modest height rises are expected across the southern/central Plains Friday night/Saturday morning with very warm mid-level temperatures (13-15 C) overspreading the western third of Oklahoma. Several models indicate a complex or two of storms will develop mainly north of Oklahoma in Kansas near the nose of a rather strong low level jet. This activity is expected to move east and southeast during the overnight, with some storms entering central and eastern parts of the area. Convective trends Saturday afternoon and night will likely depend on a possible outflow boundary from morning convection, and a cold front located across northern and western parts of Oklahoma. A capping inversion may limit convection and or storm coverage across parts of western Oklahoma/western north Texas. && .LONG TERM... (Sunday through Wednesday) Issued at 310 AM CDT Thu May 22 2025 The stormy pattern will roll on into Sunday, focused once again near a frontal boundary as a weak upper wave begins to translate eastward. With continued strong instability and sufficient wind profiles, some severe weather risk is likely to remain, though details on coverage/areas/severity are murky and will likely be highly dependent on evolution of previous day(s) thunderstorms and the aforementioned front. The surface front looks likely to accelerate east of the forecast area by early Monday, with very pleasant/unseasonably cool high temperatures (low to mid-70s) possible on Monday and Tuesday. A low (20-30%) chance for precipitation exists on Monday afternoon across the southern tier of the area, though this concern will be highly dependent on how fast the front moves/clear during the day. Ungar && .AVIATION... (18Z TAFS) Issued at 1224 PM CDT Thu May 22 2025 Area of showers and thunderstorms tracking across east-central and southern Oklahoma is resulting in some MVFR and isolated IFR conditions, currently. Storm redevelopment is expected this afternoon and evening, primarily over western north Texas into southwest Oklahoma. && .PRELIMINARY POINT TEMPS/POPS...
