  "textContent": "MD 0828 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF THE MID-MISSOURI VALLEY\n\n\n\n\n    Mesoscale Discussion 0828\n    NWS Storm Prediction Center Norman OK\n    0524 PM CDT Fri May 22 2026\n\n    Areas affected...portions of the mid-Missouri Valley\n\n    Concerning...Severe potential...Watch unlikely\n\n    Valid 222224Z - 230030Z\n\n    Probability of Watch Issuance...5 percent\n\n    SUMMARY...Isolated thunderstorms forming along/ahead of an\n    approaching cold front may bring a low-end risk for small to\n    marginally severe hail over the next few hours. Watch issuance is\n    not expected.\n\n    DISCUSSION...Latest radar imagery depicts modest deepening of a\n    low-topped thunderstorm south of the Omaha, Nebraska, vicinity, with\n    additional thunderstorm activity noted within a narrow corridor of\n    weak buoyancy (500-1000 J/kg MLCAPE per latest objective analysis).\n    While mid-level flow remains modest at best, as sampled by the OAX\n    VWP, 25-35 kts of effective bulk shear may support some organization\n    of stronger updrafts, with marginal/transient supercells possible.\n    While relatively warm mid-level temperatures (sampled above 600 mb\n    per a recent OAX ACARS profile) and generally weak mid-level lapse\n    rates (6-6.5 C/km sampled by the 18z OAX observed sounding) are\n    likely to temper overall updraft intensity, a low-end risk for small\n    to marginally severe hail may accompany the strongest updrafts. This\n    potential appears to decrease with southward extent into\n    northeastern Kansas where effective shear is lower (less than 25\n    kts). Given the limited nature of severe coverage/magnitude, watch\n    issuance is not expected.\n\n    ..Chalmers/Thompson.. 05/22/2026\n\n    ...Please see www.spc.noaa.gov for graphic product...\n\n    ATTN...WFO...DMX...EAX...OAX...TOP...\n\n    LAT...LON   38649683 38819719 39249717 40099692 41209673 41849666\n                42109648 42149607 42089580 41929557 41609540 40959526\n                40479532 39919557 39459581 39049606 38739652 38649683\n\n    MOST PROBABLE PEAK HAIL SIZE...UP TO 1.25 IN\n\n\n\nRead more",
