Mesoscale Discussion 1732 NWS Storm Prediction Center Norman OK 0723 PM CDT Tue Aug 13 2019 Areas affected...southwest KS Concerning...Severe Thunderstorm Watch 580... Valid 140023Z - 140130Z The severe weather threat for Severe Thunderstorm Watch 580 continues. SUMMARY...Corridor with widespread 60-75mph gusts expected near the bow apex for the next 0.5-2 hours. DISCUSSION...Radar mosaic/10km CAPPI shows a mature bow moving to the south-southeast between 35-40kt with a few more intense cores located near the apex of the bow. Instrument-measured observations during the past hour have sampled gusts generally in the 60-75mph range. The 00z Dodge City raob showed weak flow in the lowest 6km but veering with height resulting in around 25kt effective shear. However, steep 0-3km lapse rates (8 degrees C/km) and the mature bow with a well-defined rear-inflow jet, will probably result in a continued risk for widespread severe gusts ranging in the 60-75mph range near the apex of the bow. The bow will move towards the Dodge City vicinity during the next 1-1.5 hours prior to 9pm CDT. ..Smith.. 08/14/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...DDC...
