SPC Jun 26, 2021 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0757 PM CDT Fri Jun 25 2021 Valid 260100Z - 261200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE CENTRAL PLAINS VICINITY EAST-NORTHEASTWARD INTO THE MIDWEST... ...SUMMARY... Strong/locally severe storms will linger into tonight from portions of the southern/central High Plains into the Midwest. Locally damaging wind gusts, hail and a tornado or two remain possible. ...The Plains... Scattered showers and thunderstorms -- a good portion of which initiated over higher terrain to the west earlier this afternoon -- continue moving eastward across western Kansas/western Oklahoma and the Texas Panhandle. Another cluster of storms is moving eastward across eastern Nebraska, in the vicinity of small mid-level vort max. While a large portion of northeastern Kansas and northern Missouri has been overturned by earlier convection (which is now spreading south and southeast across central Missouri and southeastern Kansas) the environment immediately ahead of the western Kansas-to-Texas Panhandle convection remains moderately unstable. This combined with moderate mid-level flow across the area atop increasing nocturnal low-level southerlies will support local risk for severe weather -- including both marginal hail and damaging winds -- this evening. While storms will likely spread across Kansas, and portions of Oklahoma overnight, as the low-level jet increases, severe risk should gradually wane. ...The Midwest... Showers and scattered thunderstorms are ongoing at this time from northwestern Ohio and northern Indiana west-southwestward to Missouri, along a weak surface boundary. From Missouri westward into Kansas, more numerous storms -- comprising a rather large/loosely organized MCS -- continue. With ample instability near and ahead of the ongoing storms, expect locally robust convection to continue locally, aided by a belt of west-southwesterly mid-level flow around 40 kt. While gusty/locally damaging winds and marginal hail will remain the primary severe risk this evening, a tornado cannot be ruled out. Storms should gradually diminish into the overnight hours, along with any lingering/attendant severe risk. ..Goss.. 06/26/2021 Read more LIVE: spc.noaa.gov
