Mesoscale Discussion 1031 NWS Storm Prediction Center Norman OK 1016 PM CDT Sat Jun 27 2020 Areas affected...Northern KS...Southern NE Concerning...Severe Thunderstorm Watch 311... Valid 280316Z - 280515Z The severe weather threat for Severe Thunderstorm Watch 311 continues. SUMMARY...Scattered strong/severe storms will spread across mainly the northern portions of ww311. DISCUSSION...High-plains convection has evolved into a line segment, roughly 50mi in length, as it propagates across northwestern portions of the watch. Earlier, winds gusted to 50kt at Burlington CO with this squall line. Latest observational data suggest earlier surface boundary that was lifting north across southwest KS has advanced to near the I-70 corridor, and warm advection is now focused north of this wind shift. In addition, LLJ is beginning to strengthen into this zone which should aid longevity of convection as it spreads east into the early morning hours. ..Darrow.. 06/28/2020 ...Please see www.spc.noaa.gov for graphic product...
