   Mesoscale Discussion 1109
   NWS Storm Prediction Center Norman OK
   0136 PM CDT Sat Jun 01 2024

   Areas affected...northeast New Mexico...eastern Colorado...western
   Kansas...and the western OK Panhandle

   Concerning...Severe potential...Watch likely 

   Valid 011836Z - 012030Z

   Probability of Watch Issuance...80 percent

   SUMMARY...The threat for large hail and severe wind gusts is
   increasing across northeast New Mexico and eastern Colorado.

   DISCUSSION...Convection has started to form along the Front Range
   from central Colorado to northern New Mexico. Currently, the
   environment east of the mountains remains capped amid a well-mixed
   atmosphere. Another hour or two of heating should erode inhibition
   across this region and permit strong to severe storm development
   east of the mountains. Effective shear remains sufficiently strong
   (35-40 knots per SPC mesoanalysis) to support rotating updrafts
   across central Colorado with decreasing shear farther south.
   Initially, the threat will be large hail (some 2+ inch where
   supercell mode is favored), but severe wind will also be a threat
   given the inverted-v soundings, favorable for strong downdrafts.
   Eventually, expect storms to congeal into a few clusters by this
   evening with an increasing severe wind threat. A severe thunderstorm
   watch will be needed by mid-afternoon to address the threat from
   these storms.
