MD 2022 CONCERNING SEVERE THUNDERSTORM WATCH 592...594... FOR PORTIONS OF CENTRAL AND EASTERN NEBRASKA Mesoscale Discussion 2022 NWS Storm Prediction Center Norman OK 1121 PM CDT Mon Aug 17 2026 Areas affected...portions of central and eastern Nebraska Concerning...Severe Thunderstorm Watch 592...594... Valid 180421Z - 180545Z The severe weather threat for Severe Thunderstorm Watch 592, 594 continues. SUMMARY...A brief bout of severe hail or a gust may still occur with one of the stronger embedded cells within the broader thunderstorm cluster. However, the overall severe threat should diminish with time tonight. DISCUSSION...A loosely organized MCS continues to propagate eastward as cold pools with surrounding supercells and multicells merge. 04Z mesoanalysis depicts increasing MLCINH, indicating a gradually decoupling boundary layer. Ongoing storms should continue to become progressively elevated with time, which will further limit the severe threat. In the next 1-2 hours though, isolated severe hail or wind may accompany the stronger storm cores given over 2000 J/kg MUCAPE and 40+ kts of effective bulk shear in place. ..Squitieri.. 08/18/2026 ...Please see www.spc.noaa.gov for graphic product...
