Mesoscale Discussion 1262

Areas affected...Parts of southeastern WY...far northeastern
CO...and the NE Panhandle

Concerning...Severe potential...Watch unlikely=20

Valid 252138Z - 252345Z

Probability of Watch Issuance...20 percent

SUMMARY...An isolated strong to severe storm or two is possible this
afternoon/early evening. Marginally severe hail and locally severe
gusts are the primary concerns.

DISCUSSION...Isolated convective initiation is underway along the
higher terrain in southeastern Wyoming this afternoon -- aided by
low-level upslope flow and eroding MLCINH. While weak large-scale
ascent and marginal buoyancy limit confidence in storm coverage and
longevity, around 50 kt of effective shear (characterized by a
long/straight hodograph) will conditionally support splitting
supercell structures. Isolated strong/severe gusts and marginally
severe hail could accompany any persistent/organized storms that
develop over southeastern WY, far northeastern CO, and the NE
Panhandle through this evening.
