   1105 PM CDT Tue Jun 23 2026

   Areas affected...portions of far southwestern Nebraska into western
   Kansas

   Concerning...Severe potential...Watch possible 

   Valid 240405Z - 240500Z

   Probability of Watch Issuance...60 percent

   SUMMARY...The severe threat may increase through the late evening,
   with severe wind/hail becoming more widespread through tonight east
   of Severe Thunderstorm Watch 385. A WW issuance may be needed
   pending favorable trends in storm intensification.

   DISCUSSION...Multicells/transient supercells have developed along
   the CO/NE border, at the terminus of an intensifying low-level jet.
   These storms are poised to track southeastward amid 2500+ J/kg
   MUCAPE and 60 kts of effective bulk shear. As such, any storms that
   can become sustained may pose a severe hail threat, a few stones of
   which could exceed 2 inches in diameter. Isolated to potentially
   scattered severe gusts are also possible, especially if an MCS
   begins to materialize sooner than expected. If storms continue to
   increase in coverage and intensity, a Severe Thunderstorm Watch may
   be needed.
