Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
0747 PM CDT Wed Apr 27 2022

Valid 280100Z - 281200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM NORTHEAST NEW
MEXICO INTO SOUTHWEST KANSAS...

...SUMMARY...
Isolated severe wind gusts and some severe hail remain possible this
evening, especially from southwestern Kansas into the northern Texas
Panhandle and extreme northeast New Mexico.

...01z Update...

Early-evening water-vapor imagery depicts a well-defined short-wave
trough suppressing the ridge as it tracks across southeast
CO/northeast NM toward the High Plains. High-based convection has
gradually increased in areal coverage in response to this feature
and intense boundary-layer heating. It appears the LLJ will assist
an upward-evolving corridor of clusters, and a few supercells as
they propagate east, then southeast toward northwestern OK later
this evening. While hail may acco*pany this activity, especially
early, if adequate clustering occurs, or more linear structures
evolve, then damaging winds will beco*e the primary threat. This may
be occurring from Ford County KS into eastern Texas County OK where
an MCS-like co*plex appears to be forming. Have expanded severe
probabilities a bit downstream to account for this scenario.  The
air mass over south-central KS into portions of OK is not
particularly buoyant, and this activity should weaken as it
encounters more stable conditions.
