Given the short-lived nature of the severe threat, a WW issuance is not expected. DISCUSSION...A small MCS has organized along the CO/KS border, supported by a strong cold pool (per latest surface observations) and strong surface-10 kft rear inflow (per KGLD inbound velocities). The ambient environment can be characterized by steep surface-500 mb lapse rates and a dry boundary layer (when subjectively interpolating between the 00Z DDC and LBF observed soundings), with over 35 kts of line-normal effective bulk shear (per 00z mesoanalysis). This ambient environment will support continued severe gusts while the boundary layer remains coupled/well-mixed. However, decoupling associated with nocturnal cooling should temper the severe threat to a degree in the next couple of hours, so the organized severe wind threat is expected to be short-lived. As such, a Severe Thunderstorm Watch is not currently anticipated. ...Squitieri/Grams.. 07/27/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!5fqqoGYs_AlnWtVrhWztNcrxZN1n4yqoMxuopHdCPJQ3ayw0nKHBsgJ_IchK5MQWOPE8zYRZU= 5GWXVdyPfOLRcslwWU$ for graphic product...
