A WW issuance is not expected. DISCUSSION...Convective initiation/intensification is underway across the Higher Terrain of WY/CO. Ahead of the developing storms, a well-mixed boundary layer has materialized, characterized by 30 F surface temperature/dewpoint spreads and 9-10 C/km 0-3 km lapse rates (per 20Z mesoanalysis). Forecast soundings depict around 500 J/kg of tall/thin MLCAPE, distributed in roughly the 700-300 mb layer. Given elongated hodographs, storms that can mature in this environment may produce a couple instances of severe hail/wind. However, the severe threat should be sparse and a WW issuance is not anticipated. ...Squitieri/Guyer.. 08/10/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!6pC6wlv0QibnWy2cL2C_86QqzRqf5LAt0tr57by_8oCi-QB0klrRYVYKSl5w7xnUqYRzVRVGC= _3elwKVuzezGim5DqM$ for graphic product...
