Mesoscale Discussion 0826 NWS Storm Prediction Center Norman OK 0303 PM CDT Sat May 18 2024 Areas affected...parts of central and northern Wisconsin into western Upper Michigan Concerning...Severe potential...Watch possible Valid 182003Z - 182200Z Probability of Watch Issuance...40 percent SUMMARY...Storms will increase in coverage over the next few hours, with areas of strong to locally damaging gusts and marginal hail. DISCUSSION...Strong heating across the area has resulted in up to 1000 J/kg MLCAPE as temperatures rise through the 80s F. A prominent cold front/wind shift is moving across western WI and into the western MI U.P. with signs of deepening convection within a pre-frontal warm conveyor. Winds veering with height which may tend to favor cellular storm mode, with a broken line of storms possible along the front. This may favor hail initially. With time, outflows may consolidate, with perhaps linear segments along the front aiding wind potential. Midlevel wind speeds averaging near 40 kt along with the steep boundary layer lapse rates may tend to favor strong outflow production this afternoon into the early evening. ..Jewell/Hart.. 05/18/2024 ...Please see www.spc.noaa.gov for graphic product...
