Mesoscale Discussion 0581 NWS Storm Prediction Center Norman OK 0847 PM CDT Sun Apr 27 2025 Areas affected...Parts of northwest/north-central Nebraska Concerning...Tornado Watch 178... Valid 280147Z - 280245Z The severe weather threat for Tornado Watch 178 continues. SUMMARY...The supercell tornado risk continues across portions of northwest into north-central Nebraska. DISCUSSION...Several long-lived right-moving supercells have merged into a supercell cluster over the last hour over Cherry County Nebraska. The LNX VWP depicts a 50-kt low-level jet overspreading backed surface winds -- yielding a large clockwise-curved hodograph (280 m2/s2 0-500m SRH). This wind profile, combined with rich boundary-layer moisture (lower 60s dewpoints) will continue to support a supercell tornado threat with northeastward extent over at least the next hour. ..Weinman.. 04/28/2025 ...Please see www.spc.noaa.gov for graphic product...
