Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0813 PM CDT Sun May 19 2024 Valid 200100Z - 201200Z ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF SOUTHERN/CENTRAL KANSAS... ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR NORTH-CENTRAL SOUTH DAKOTA AND SOUTHERN NORTH DAKOTA... ...SUMMARY... Severe thunderstorms capable of widespread damaging winds and large hail are expected to persist this evening across portions of southern/eastern Kansas and northern Oklahoma. ...Central Plains... 2 storms clusters have now congealed into a large line of storms across central and southern Kansas. This line of storms has a history of producing 75 to 100 mph winds earlier this evening. While the extreme wind threat is likely over, 70-80 mph winds are still possible for a few more hours as this squall line moves east across southeast Kansas with some wind threat expected to persist into Missouri during the overnight period. See MCD 842 for additional information. Farther south, a persistent, large supercell continues across western Oklahoma. This supercell has a history of baseball sized hail and at least one tornado. This storm will encounter increasing inhibition as the boundary layer continues to cool ahead of it. The HRRR suggests additional supercells may develop across northwest/northern Oklahoma late this evening along the trailing outflow boundary from the Kansas MCS as the low-level jet strengthens. These storms will have primary threats of large hail and severe wind gusts, although a tornado or two may also be possible. ...Dakotas... A cluster of storms produced a swath of damaging wind gusts across western South Dakota this afternoon and early evening. This threat has mostly abated, but additional supercells have developed near the ND/SD border which will pose a threat of damaging winds and large hail for a few more hours this evening.
