It is not clear that a severe weather watch is needed, but trends will continue to be monitored for this possibility. DISCUSSION...Low-level forcing for ascent is rather weak, but a lingering confluence zone near the interface of a corridor of stronger surface heating and modest boundary-layer moisture is becoming the focus for destabilization across parts of northwestern Oklahoma through eastern Kansas. While this is likely to remain characterized by mixed-layer CAPE less than 1000 J/kg, low-level lapse rates are becoming steep beneath seasonably cool mid-level air around -18C. Scattered convection is beginning to from and deepen in response to the continuing surface heating, and model output generally indicates that this will lead to the development of a few thunderstorms by 23-00Z. It appears that stronger storms may gradually focus where deep-layer shear and mid-level forcing for ascent become maximized, near the left exit region of a digging northerly mid-level jet streak (around 40 kt at 500 mb), roughly near and south-southwest of the Enid vicinity. Given the environment, some of these storms may pose a risk for (mostly) sub-severe to marginally severe hail and wind gusts. ...Kerr/Guyer.. 04/10/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!-1V-Fn1zRYUlsV0h_hSCk8eNDlOOvsiLJ8WUbcR6c_Ub9c5HKfw6OyG5TPePi_Y45DdAsvCMT= V4TwNZ5RW6cpbmEW0k$ for graphic product...
