MD 0745 CONCERNING SEVERE THUNDERSTORM WATCH 211...212... FOR NORTHEAST KANSAS...SOUTHEAST NEBRASKA...AND NORTHWEST MISSOURI Mesoscale Discussion 0745 NWS Storm Prediction Center Norman OK 1233 AM CDT Sun May 17 2026 Areas affected...northeast Kansas...southeast Nebraska...and northwest Missouri Concerning...Severe Thunderstorm Watch 211...212... Valid 170533Z - 170700Z The severe weather threat for Severe Thunderstorm Watch 211, 212 continues. SUMMARY...Damaging wind threat should continue for the next 1-2 hours with a fast moving bowing segment moving across northeast Kansas and southeast Nebraska. Farther east, large hail will remain possible across portions of far northern Missouri. DISCUSSION...A well organized linear bowing segment continues to quickly move east this morning. The overall environment along and immediately ahead of the MCS remains conducive for damaging thunderstorm winds, with measured wind gusts within the last hour in excess of 85 mph. In the next 1-2 hours, the ongoing bowing segment should move into a less favorable environment across northern Missouri where ongoing thunderstorms continue to reinforce a stable boundary layer. In turn, this should begin to lessen the overall damaging wind threat. Given the current speed of the bowing segment, a local extension in time for Severe Thunderstorm Watch 211 may be required across eastern/southeastern portions of the watch. Farther east, the aforementioned thunderstorms across northern Missouri will continue to have the potential to produce large hail as they remain rooted within an elevated CAPE reservoir. An isolated damaging wind gust cannot be ruled out. ..Marsh.. 05/17/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...DMX...EAX...OAX...TOP...
