Valid 130211Z - 130415Z The severe weather threat for Severe Thunderstorm Watch 407 continues. SUMMARY...The threat of large hail persists over a small area of eastern Nebraska into western Iowa in the near term. Storms will likely shrink in size during the next 1-2 hours. DISCUSSION...A pair of large supercells with history of very large hail remain over western IA into far eastern NE near the Omaha area. The 00Z sounding from OAX shows a rather deep moist layer up to nearly 700 mb, not far from the LFC, with favorable deep-layer shear. Given the loss of heating, the cooling boundary layer will gain convective inhibition relatively quickly, perhaps in the next hour, which should result in a weakening trend with these cells. Until then, hail will remain likely through about 03-04Z, with locally gusty winds as well prior to ..Jewell.. 06/13/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OAX...
