Isolated large hail and damaging gusts are possible with these storms. Limited overall severe coverage is expected to preclude watch issuance. DISCUSSION...Thunderstorms have developed over northwest KS, in the vicinity of a remnant MCV drifting gradually eastward. Additional storms have developed farther northeast into north-central NE, along a southwestward-progressing outflow boundary. Another cluster of storms appears to be developing in the vicinity of the surface low over central NE. Continued mesoscale forcing for ascent from each of these mechanisms is expected to result in increased thunderstorm coverage this afternoon. The airmass is moderately buoyant but weakly sheared, which is expected to result in a predominantly multicellular mode. Even so, the moderate buoyancy will still result in robust updrafts, with some storms capable of isolated large hail and strong downdrafts. Lone supercell over Wheeler County NE appears to be significantly overachieving given the environment, giving additional credence to the potential for more severe thunderstorms this afternoon. However, given the overall environment, the severe coverage is currently expected to remain isolated, likely precluding the need for a watch. ...Mosier/Thompson.. 06/09/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!5rUE8kAq25c_DC82iPZ1nA6csa_Tj3CYAGvzYo834q9d00WpHplbmxdw1mJ0-WH-G18lrz66_= A8LRkz0mxTgCW9sYLQ$ for graphic product...
