With time, severe potential is expected to increase from northeast Missouri into southeast Iowa. A watch will likely be needed in the next few hours, but timing is uncertain. DISCUSSION...Elevated convection developing across central Missouri may initially pose a marginally severe hail risk over the next 1-2 hours. Moderate to strong MLCINH is still apparent from central MO into southeast IA late this morning, stronger heating is underway amid broken cloudiness. Temperatures have warmed into the low to mid 70s F amid low 60s F dewpoints, resulting in modest destabilization. With continued heating and eastward progression of large-scale ascent impinging on the area by early afternoon, capping should sufficiently erode such that severe potential will gradually increase over the next few hours. Quite a bit of uncertainty still exists in the exact evolution of storms given areas of ongoing convection and cloud cover. Additionally, more than one round of storms appears possible for parts of the region. Altogether, this is resulting in uncertainty in timing of watch issuance. Trends will continue to be monitored for watch issuance within the next few hours. ..Leitman/Guyer.. 04/16/2024 ...Please see www.spc.noaa.gov for graphic product...
