932 ACUS11 KWNS 190127 SWOMCD SPC MCD 190127 KSZ000-190330- Mesoscale Discussion 1991 NWS Storm Prediction Center Norman OK 0827 PM CDT Mon Aug 18 2025 Areas affected...Northwestern Kansas...Southwest Nebraska Concerning...Severe Thunderstorm Watch 601... Valid 190127Z - 190330Z The severe weather threat for Severe Thunderstorm Watch 601 continues. SUMMARY...Strong gusts along with some hail threat continues across northwestern Kansas into southwest Nebraska. DISCUSSION...Much of the western half of ww601 has stabilized due to extensive convective overturning. Surface temperatures have cooled into the 60s across northeast CO and the more buoyant air mass now resides downstream across the central Plains. Strong, slow-moving thunderstorms continue along a boundary that is draped from Greeley County-Ellis County KS, but even this activity has gradually weakened over the last hour or so. Given the lack of meaningful large-scale support, or a strong LLJ, severe wind/hail risk should be more isolated in nature as storms propagate slowly this evening. ..Darrow.. 08/19/2025 ...Please see www.spc.noaa.gov for graphic product...
