0655 PM CDT Mon Jun 29 2020
Areas affected...North central Texas
Concerning...Severe potential...Watch unlikely
Valid 292355Z - 300130Z
Probability of Watch Issuance...20 percent
SUMMARY...There is a locally enhanced severe weather threat in
north-central Texas for the remainder of the evening.
DISCUSSION...At least 3 supercells have developed in Shackelford and
Throckmorton counties in the last hour. These storms have formed in
an environment with over 3000 J/kg MLCAPE per SPC mesoanalysis with
effective shear around 30 knots per KDYX VWP. This environment will
continue to support at least transient supercell structures with
this activity. The primary threats will be large hail and damaging
winds. These storms are surface based, and thus, given the lack of a
strong upper-level forcing, should weaken considerably after 9PM as
the boundary layer cools.
