NWS Storm Prediction Center Norman OK
0745 PM CDT Tue Apr 01 2025
Areas affected...Portions of central and northwest Texas
Concerning...Severe potential...Watch possible
Valid 020045Z - 020245Z
Probability of Watch Issuance...40 percent
SUMMARY...Isolated large hail and locally severe gusts are possible
with initial discrete storms in central/northwest Texas. It is
unclear if severe coverage will warrant a watch, though trends are
being monitored.
DISCUSSION...An isolated thunderstorm has developed ahead of the
dryline in central/northwest Texas -- where steep boundary-lapse
rates are intersecting the western edge of the warm/moist sector
(upper 50s/lower 60s F dewpoints). Weak large-scale forcing for
ascent and 40-50 kt of cross-boundary 0-6 km shear (per DYX VWP)
will support discrete supercellular structures, aided by around 2000
J/kg MLCAPE. Initial storms will mainly pose a risk of isolated
large hail and locally severe gusts. However, if these storms can
persist long enough and track eastward into the increasing low-level
shear/SRH, the tornado threat would also increase. The overall
coverage and evolution of storms remains unclear, though trends are
being monitored for a possible watch.
