MD 1695 CONCERNING SEVERE THUNDERSTORM WATCH 495… FOR SOUTHEAST NEBRASKA INTO PARTS OF NORTHEAST AND CENTRAL KANSAS
Mesoscale Discussion 1695 NWS Storm Prediction Center Norman OK 0650 PM CDT Fri Oct 06 2017 Areas affected...southeast Nebraska into parts of northeast and central Kansas Concerning...Severe Thunderstorm Watch 495... Valid 062350Z - 070115Z The severe weather threat for Severe Thunderstorm Watch 495 continues. SUMMARY...Severe storms over central Kansas will continue to track east-northeast into the MCD area this evening. Hail and strong wind gusts will be the main concern with these storms into tonight. DISCUSSION...Radar trends over the last hour show a transition from discrete supercell structures over western Kansas into clusters and bowing line segments as storms track east across central Kansas. This should result in a diminishing large hail threat into the nighttime hours. MRMS MESH trends over the last hour seem to support this notion as values have been decreasing even in semi-discrete cells. Somewhat poorer lapse rates and instability across northeast Kansas into southeast Nebraska also are likely contributing to a downward trend in hail indicators. Regardless, the environment will continue to support at least a marginal hail threat this evening. As storms continue to grow upscale into a better organized line, damaging winds will become the main concern with eastward extent. ..Leitman.. 10/06/2017 ...Please see www.spc.noaa.gov for graphic product...
