Large hail\n    will be the primary hazard initially, with damaging wind potential\n    increasing this afternoon. A Severe Thunderstorm watch will likely\n    be required to address this severe weather threat.\n\n    DISCUSSION...Recent radar trends indicate thunderstorms gradually\n    increasing in coverage across portions of eastern OK, driven largely\n    by a low-level warm advection regime occurring to the north of a\n    surface boundary stalled across southeast OK into central AR. RAP\n    proximity soundings suggest the developing storms are rooted in a\n    moist layer centered around 850 mb, with steep mid-level lapse rates\n    contributing to MUCAPE of 1500-2000 J/kg.\n\n    Water vapor imagery shows a vigorous short-wave trough moving into\n    western KS this morning with an area of downstream, implied forcing\n    for ascent progressively overspreading the discussion area over the\n    next several hours. That combined with the available reservoir of\n    moderate, elevated instability, and relatively strong cloud-bearing\n    shear will support the potential for elevated supercells capable of\n    large hail initially. Some cloud breaks (evident in visible\n    satellite) may allow for a subset of the elevated storms to become\n    surface-based by afternoon, at which point, a damaging wind threat\n    would increase.\n\n    ..Mead/Guyer.. 04/28/2026\n\n    ...Please see www.spc.noaa.gov for graphic product...\n\n    ATTN...WFO...PAH...LSX...LZK...SGF...TSA...\n\n    LAT...LON   35769576 36959488 37869282 37869097 36649096 36149149\n                35549395 35169505 35769576\n\n    MOST PROBABLE PEAK TORNADO INTENSITY...100-125 MPH\n    MOST PROBABLE PEAK WIND GUST...55-70 MPH\n    MOST PROBABLE PEAK HAIL SIZE...2.00-3.50 IN\n\n\n\nRead more",
