Mesoscale Discussion 0666 NWS Storm Prediction Center Norman OK 0913 PM CDT Mon May 06 2024 Areas affected...Parts of southwest into central/northeast OK Concerning...Tornado Watch 189... Valid 070213Z - 070315Z The severe weather threat for Tornado Watch 189 continues. SUMMARY...A threat for tornadoes, hail, and severe gusts will approach the I-35 corridor in central OK through 10 PM CDT, with redevelopment still possible into southwest OK. DISCUSSION...A tendency toward upscale growth has been noted this evening from northern into west-central OK, with embedded supercells tending to traverse the outflow of downstream storms, resulting in a gradually expanding cold pool. As a result, cells have generally struggled to become tornadic, despite a very favorable environment across the region. While the storm mode is currently rather unfavorable, any persistent discrete supercell will still pose a tornado threat. Conditional strong tornado potential remains evident across the region, with strong buoyancy and deep-layer shear, and 0-1 km SRH of around 300 m2/s2. Line-embedded tornadoes will also be possible, especially if any more prominent bowing segments can develop. The greatest short-term tornado threat may be associated with the trailing cells in the cluster, if they can avoid being undercut by outflow. These cells will approach the I-35 corridor in central OK through 10 PM CDT. The discrete cell moving into southeast Osage County in northeast OK will also pose a tornado threat. Farther southwest, a cluster of cumulus remains evident on IR satellite into southwest OK and northwest TX, and redevelopment remains possible across this region a little later this evening, as the Pacific cold front continues to move eastward, and increasing ascent noted on WV imagery begins to overspread the warm sector. While evolution of any later development remains somewhat uncertain, supercells capable of all severe hazards would be possible if additional storms develop. ..Dean.. 05/07/2024 ...Please see www.spc.noaa.gov for graphic product...
