MD 0878 CONCERNING SEVERE THUNDERSTORM WATCH 242… FOR SOUTHEASTERN MONTANA
Mesoscale Discussion 0878 NWS Storm Prediction Center Norman OK 0718 PM CDT Fri May 26 2023 Areas affected...Southeastern Montana Concerning...Severe Thunderstorm Watch 242... Valid 270018Z - 270215Z The severe weather threat for Severe Thunderstorm Watch 242 continues. SUMMARY...Despite some decrease in buoyancy, a modest increase in shear into Montana may allow for a brief increase in some storm intensities over the next 1-2 hours. DISCUSSION...Semi-discrete convection continues to the north into southeastern Montana. Modest diurnal cooling has already been noted on recent surface observations. Storms, however, are moving into an environment with nominally greater shear. Over the next 1-2 hours, some activity could see a brief uptick in intensity. Large hail and isolated strong/damaging winds would be a possibility. Unless greater cold pool organization occurs, storms should steadily decrease in intensity as further surface stabilization occurs into the later evening. ..Wendt.. 05/27/2023 ...Please see www.spc.noaa.gov for graphic product...
