Valid 202101Z - 202230Z The severe weather threat for Severe Thunderstorm Watch 523, 524 continues. SUMMARY...Some threat for damaging wind and hail will continue into early evening. DISCUSSION...While a well-organized bowing cluster has moved into Ontario, somewhat more discrete storms are ongoing along a cold front into northeast IN and extreme southeast MI. With moderate buoyancy and increasing deep-layer shear (as noted in the 20Z ILN and PIT soundings) in advance of a midlevel shortwave trough moving across MI, strong to potentially severe storms will persist into early evening and perhaps increase in coverage into parts of northern OH. Relatively steep midlevel lapse rates will continue to support a large hail threat with any of the more discrete cells, with some potential for an increasing damaging wind threat as one or more upscale growing clusters eventually evolve with time.=20 Farther southwest, prefrontal storms across central IN had shown a weakening trend after their initial development, but some strengthening has been noted again over the last 30 minutes. While large-scale ascent is somewhat weaker compared to areas farther north/east, a few stronger storms may pose a hail and damaging wind threat as they approach southeast IN and southwest OH into early evening. ...Dean.. 07/20/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!83Vc8P3SWwPUa3RnI81GtjfVi3dE4rJItCVLFOzHaezpFSlUasRo898oeO4YVSPvsQ5pjzuYG= -xh4ykVh6_5KtKeDfE$ for graphic product...
