Thunderstorm coverage is expected to increase this evening across southwest/south-central Nebraska and northwest/north-central Kansas. Strong buoyancy and vertical shear will support the potential for large to very large hail over the next few hours when a more cellular mode is favored. A low-probability tornado risk exists during this time period as well. Thereafter, a trend towards a more linear storm mode is possible, with the primary severe threat transitioning to strong gusts. Isolated gusts may approach 75 mph.
