Mesoscale Discussion 1708 NWS Storm Prediction Center Norman OK 0713 PM CDT Sun Aug 11 2019 Areas affected...northeast Colorado and western Nebraska Concerning...Severe Thunderstorm Watch 570... Valid 120013Z - 120215Z The severe weather threat for Severe Thunderstorm Watch 570 continues. SUMMARY...Severe weather continues moving quickly eastward across WW 570, and will shift east of the watch in northwest Nebraska over the next hour. A new WW may be needed. DISCUSSION...Latest radar loop shows storms now accelerating eastward across WW 570, moving into downstream Tornado Watch 572 in southwest Nebraska/northwest Kansas and far northeast Colorado. Farther north, storms will begin moving out of the watch across northwest Nebraska. With risk for primarily damaging winds potentially accompanying this convection as it exits the eastern fringe of WW 572, a new WW, or WW extension in area, may be needed. ..Goss.. 08/12/2019 ...Please see www.spc.noaa.gov for graphic product...
