Areas affected...Northern Texas into southwest Oklahoma

Concerning...Severe potential...Watch unlikely 

Valid 301743Z - 301915Z

Probability of Watch Issuance...20 percent

SUMMARY...A developing cluster of storms in northern Oklahoma will
likely strengthen this afternoon as it moves into Oklahoma. These
storms may produce some large hail and damaging winds as the storms
move northeast this afternoon and into the evening.

DISCUSSION...A cluster of storms has started to develop in northern
Texas ahead of a weak MCV. As the boundary layer destabilizes
further across Oklahoma this afternoon, these storms will likely
continue to strengthen. Deep-layer shear is weak across much of the
Southern Plains, however the VWP from FDR and DYX is sampling an
area of enhanced mid-level flow (35 to 40 knots around 5 km)
associated with this MCV. Therefore, this combination of strong to
very strong instability across Oklahoma combined with the locally
enhanced shear associated with the MCV will provide an environment
supportive of one or more multicell clusters. The primary threat
from these storms will be large hail and damaging winds. No watch is
expected ahead of the current convection, however a watch may be
needed later this afternoon if this convection grows upscale and
becomes a more widespread threat.
