Mesoscale Discussion 1129
NWS Storm Prediction Center Norman OK
0351 PM CDT Sat Jun 17 2023
Areas affected...southeast Colorado...southwest Kansas...Oklahoma
Panhandle and northwest Oklahoma...portions of the eastern Texas
Panhandle
Concerning...Severe potential...Watch likely
Valid 172051Z - 172245Z
Probability of Watch Issuance...80 percent
SUMMARY...Severe thunderstorms are expected to develop along a
dryline over the next 1 to 2 hours, with large to very large hail,
damaging winds and a couple tornadoes possible. Trends will
continue to be monitored and a watch is likely in the next 1 to 2
hours.
DISCUSSION...Supercell thunderstorm development is likely to occur
along a dryline that extends through the central Texas Panhandle
north across the western OK Panhandle over the next couple of hours,
within a moderate-strongly unstable environment and 50-60 kts of
westerly deep-layer shear. Large to very large hail will be
possible given very steep mid-level lapse rates and considerable
CAPE in the -10C to -30C layer, and damaging gusts will also be
possible. Some potential will exist for low-level rotation and a
tornado or two as low-level hodographs become more favorable towards
early evening. With time, storms are likely to merge into an
eastward-moving MCS capable of all severe hazards and an increasing
risk for significant severe wind gusts.
Short-term trends will continue to be monitored and a watch will
likely be needed in the next 1 to 2 hours.
