DISCUSSION...An intense cluster of cells has developed near the surface trough over northern NE, under the influence of the upper wave moving across the Dakotas. Temperature aloft are relatively cool, with midlevel westerlies around 40 kt aiding deep-layer shear for storm longevity. Surface temperatures are cool and in the low 60s F, but stronger south/southwest winds just off the surface are likely aiding destabilization and storm relative inflow within the 850 mb theta-e gradient. Given the relatively large size of the complex and favorable elevated influx of moisture out of the south/southwest, it seems likely that hail and locally damaging wind potential will persist within a narrow zone immediately to the southeast. Trends will continue to be monitored for any additional expansion in threat area, and watch potential could be reconsidered at that time. ..Jewell/Gleason.. 06/23/2026 ...Please see www.spc.noaa.gov for graphic product...
