1118 PM CDT Tue Apr 25 2023

Areas affected...North TX into far southern OK

Concerning...Severe potential...Watch unlikely 

Valid 260418Z - 260615Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated hail is possible overnight. Watch issuance is
considered unlikely.

DISCUSSION...A strengthening low-level jet (as noted on recent KDYX
and KFWD VWPs) is likely contributing to a recent increase in
elevated convection across north-central TX. Meanwhile, a cluster of
elevated convection associated with the remnant of an earlier
long-lived supercell is moving eastward across western north TX.
While increasing MLCINH will tend to suppress the redevelopment of
surface-based convection, MUCAPE of greater than 1000 J/kg and
effective shear of 40-50 kt will support some modestly organized
elevated storms. A tendency for storm clustering may limit the
threat to some extent (compared to more discrete development), but
isolated hail will be possible with the strongest storms overnight.
With the magnitude and coverage of this threat expected to remain
relatively limited, watch issuance is considered unlikely at this
time.
