Watch issuance appears unlikely. DISCUSSION...High-based thunderstorms have developed along and east of the higher terrain in southeastern WY. This activity is occurring in a post-frontal, low-level upslope flow regime. Limited low-level moisture behind the cold front should hinder the development of any more than weak instability this afternoon. Still, up to around 1000 J/kg of MUCAPE, along with somewhat steepened mid-level lapse rates, should be enough for robust thunderstorms. A west-northwesterly flow regime aloft is supporting around 30-35 kt of effective bulk shear. Isolated thunderstorms that can persist may acquire occasional supercellular characteristics as they move southeastward this afternoon and early evening, with a related threat for large hail and severe downdraft wind gusts. Overall severe potential should be limited by the weak instability, and watch issuance appears unlikely at this time. ...Gleason/Bunting.. 07/14/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!-Wnfubv2Esz4Bj_xvScWv8vbHp6uMVRnaDC2xgfjJ0FtpQ2hKgKqcNfGznNy1cmvN4bJly4go= NHQwM3C0OCewBB27a0$ for graphic product...
