jojo762 Posted March 7, 2017 Share Posted March 7, 2017 Mesoscale Discussion 0266 NWS Storm Prediction Center Norman OK 0916 PM CST Mon Mar 06 2017 Areas affected...Far eastern Oklahoma into northwestern Arkansas Concerning...Tornado Watch 64... Valid 070316Z - 070515Z The severe weather threat for Tornado Watch 64 continues. SUMMARY...Tornadic supercells may eventually evolve out of a cluster of storms currently over eastern Oklahoma and northwestern Arkansas. DISCUSSION...Radar shows a cluster of storms increasing in intensity and coverage across much of northwestern AR into far eastern OK. Cells are already showing mesocyclones at times. This cluster of developing and evolving cells will continue to have access to relatively warmer surface air with mid 70s upstream as dewpoints remain in the lower 60s. Given these storms are well ahead of the cold front, a few of them could become tornadic supercells. A strong tornado could occur given extreme/rare shear values with 0-1 km SRH of 500-600 m2/s2 and continued pressure falls as the surface trough approaches. Additional pre-frontal discrete storms may also form farther west of the current cluster, just before the cold front/squall line moves through. ..Jewell.. 03/07/2017 Link to comment Share on other sites More sharing options...
