MD 1603 CONCERNING SEVERE THUNDERSTORM WATCH 524... FOR NORTHWEST TO EAST-CENTRAL MN
Mesoscale Discussion 1603 NWS Storm Prediction Center Norman OK 0847 PM CDT Sat Jul 13 2024 Areas affected...northwest to east-central MN Concerning...Severe Thunderstorm Watch 524... Valid 140147Z - 140315Z The severe weather threat for Severe Thunderstorm Watch 524 continues. SUMMARY...A small cluster with an embedded supercell may evolve into a small bow and move southeastward across parts of central Minnesota tonight. This may yield a confined swath of damaging winds and some hail, with an additional severe thunderstorm watch likely. DISCUSSION...A trio of updrafts persist over northwest MN in Clay and Becker counties, the more prominent of which has been a supercell on the western flank. This specific supercell along the composite front/outflow appears to be developing a substantial enough cold pool for potential acceleration and bowing evolution as it likely tracks along the pronounced MLCAPE gradient to its southeast. The 00Z MPX sounding in the midst of the gradient sampled ample buoyancy and favorable west-northwesterly mid to upper-level flow to support an organized strong to severe wind threat tonight. While low-level flow will remain modest, the degree of warm theta-e advection should be adequate to sustain a small MCS. Latest trends suggest this will likely impact areas along the I-94 corridor into the overnight. ..Grams/Gleason.. 07/14/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1602 CONCERNING SEVERE THUNDERSTORM WATCH 522...525... FOR SOUTHEAST MONTANA
Mesoscale Discussion 1602 NWS Storm Prediction Center Norman OK 0757 PM CDT Sat Jul 13 2024 Areas affected...Southeast Montana Concerning...Severe Thunderstorm Watch 522...525... Valid 140057Z - 140300Z The severe weather threat for Severe Thunderstorm Watch 522, 525 continues. SUMMARY...The threat for severe hail and wind continues as a cluster of semi-discrete storms moves into southeast Montana. Gradual upscale growth is still expected later this evening as storms move towards the Dakotas. DISCUSSION...Despite numerous storm interactions, the predominant storm mode has remained supercellular across eastern MT. At least two supercells continue to exhibit robust mid-level mesocyclones based on KGGW velocity imagery, suggesting that these storms may persist for the next hour or two with an attendant large hail threat. Strong right-mover supercell motion continues to favor a mean south/southeasterly storm motion, but propagation along a diffuse buoyancy gradient may result in a more southeasterly motion with time. Gradual upscale growth is still anticipated later this evening as this cluster of semi-discrete storms migrates further into southeastern MT. Early hints of a somewhat more consolidated cold pool are noted in lowest-tilt velocity imagery between the cells, suggesting that eventual upscale growth remains probable - though the exact timing remains uncertain. Recent probabilistic hazard guidance suggests the wind threat should slowly increase as the cluster migrates closer to the ND/SD border. ..Moore.. 07/14/2024 ...Please see www.spc.noaa.gov for graphic product...
