MD 0960 CONCERNING SEVERE POTENTIAL…WATCH POSSIBLE FOR PORTIONS OF THE MISSOURI VALLEY
Mesoscale Discussion 0960 NWS Storm Prediction Center Norman OK 0440 PM CDT Sat Jun 30 2018 Areas affected...Portions of the Missouri Valley Concerning...Severe potential...Watch possible Valid 302140Z - 302315Z Probability of Watch Issuance...60 percent SUMMARY...Developing storms will pose a risk of damaging winds and large hail. A watch may be needed if convective trends warrant. DISCUSSION...A very evident MCV is lifting north/northeast towards the Kansas/Nebraska border this afternoon. Focused ascent ahead of and on the eastern flank of this circulation is assisting new convective development from the MCV to the KC Metro late this afternoon. Regional VWP data are not sampling much directional shear, but strong buoyancy combined with enhanced southwesterly flow aloft (around 35-45 kt at 6 km) will likely support damaging downburst winds and isolated large hail with cluster/multicellular modes. Convective coverage/organization may warrant new watch issuance. ..Picca/Thompson.. 06/30/2018 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...DMX...EAX...OAX...TOP...ICT...
