Valid 290233Z - 290430Z The severe weather threat for Severe Thunderstorm Watch 413 continues. SUMMARY...Gusty winds will accompany convection as it spreads into northeast Montana. DISCUSSION...A semi-organized cluster of convection that matured over central MT has progressed into the eastern portions of ww413. This activity continues its northeast forward propagation into an air mass that has gradually cooled, but remains adequately buoyant for maintaining robust updrafts. Gusty winds have been noted with these storms and locally severe remains possible for the next few hours as it spreads across the plains, primarily between GGW and MLS, eventually progressing into far northeast MT where further weakening is anticipated. ..Darrow.. 06/29/2022 ...Please see www.spc.noaa.gov for graphic product...
