Administrators NorthGeorgiaWX Posted July 17 Administrators Posted July 17 MD 1672 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR EXTREME SOUTHEAST WY INTO THE NE PANHANDLE...EASTERN CO AND EXTREME WESTERN KS Mesoscale Discussion 1672 NWS Storm Prediction Center Norman OK 0349 PM CDT Wed Jul 17 2024 Areas affected...Extreme southeast WY into the NE Panhandle...eastern CO and extreme western KS Concerning...Severe potential...Watch possible Valid 172049Z - 172245Z Probability of Watch Issuance...40 percent SUMMARY...Trends are being monitored for an increasing severe-wind threat. Isolated hail remains possible. DISCUSSION...At 2045 UTC, convective outflow was moving southward near the common border of WY/NE/CO, southeast of Cheyenne, and some recent tendency for increasing convection near the outflow has been noted. In the short term, moderate buoyancy (MLCAPE of 1000-1500 J/kg) and marginally sufficient deep-layer shear could continue to support isolated marginal supercells, with an attendant threat of large hail and localized severe gusts. There is some potential for this outflow to grow with time and potentially consolidate with outflow from storms closer to the CO Front Range. Should this occur, a somewhat greater severe-wind threat could evolve late this afternoon into early evening, and watch issuance would be possible in order to address this threat. Otherwise, occasionally organized semi-discrete cells could continue to pose a threat of isolated hail and severe gusts across parts of eastern CO and adjacent portions of southeast WY and western NE/KS through late afternoon. ..Dean/Hart.. 07/17/2024 ...Please see www.spc.noaa.gov for graphic product...
