Areas affected...Northwest Oklahoma into Southwest Kansas
Concerning...Severe potential...Watch likely=20
Valid 181931Z - 182130Z
Probability of Watch Issuance...95 percent
SUMMARY...Large to very-large hail, severe winds, and tornadoes will
be possible this afternoon. The degree of tornado/very-large hail
threat will depend on a discrete storm mode. A watch is likely.
DISCUSSION...Towering cumulus are increasing in the vicinity of
Dodge City as convergence along a cold front has increased over the
past couple of hours. With 40+ kt of effective shear and observed
7.9 C/km mid-level lapse rate on the 18Z DDC sounding, initial
supercells capable of very-large hail and severe winds can be
expected. Tornadoes will also be possible where discrete modes can
be maintained longer given the low-level shear. However, the linear
forcing from the cold front may be enough to encourage a quick
transition to a more linear mode. Regardless of the exact evolution,
all severe hazards will be possible. A watch will likely be needed
this afternoon.
