MD 0711 CONCERNING SEVERE THUNDERSTORM WATCH 172…173… FOR NORTHEAST KANSAS…NORTHWEST MISSOURI…SOUTHERN IOWA
Mesoscale Discussion 0711 NWS Storm Prediction Center Norman OK 0932 PM CDT Mon Jun 11 2018 Areas affected...northeast Kansas...northwest Missouri...southern Iowa Concerning...Severe Thunderstorm Watch 172...173... Valid 120232Z - 120430Z The severe weather threat for Severe Thunderstorm Watch 172, 173 continues. SUMMARY...A threat of damaging wind and hail continues across the watch area, and may extend into the remainder of southeast Kansas and western Missouri this evening. DISCUSSION...An MCS stretches from northeast KS into south central IA as of 0230Z. Northern portions of the line previously contained measured severe winds, but, may begin to weaken a bit as the most unstable air remains to the southwest. The bulk of the MCS was beginning to propagate in a more southerly direction, with locally damaging outflow winds along with embedded hail cores. A very unstable air mass extends from OK across eastern KS, and this air mass should maintain the MCS as it travels across the severe thunderstorm watch. Another watch may be needed later this evening for portions of southeast KS and western MO, should the storms still be severe at that time. Farther north into central IA, the threat appears more marginal for both wind and hail, with a gradual weakening trend expected as these storms encounter a stabilizing air mass due to cool east winds. ..Jewell.. 06/12/2018 ...Please see www.spc.noaa.gov for graphic product...
