Areas affected...portions of north Texas

Concerning...Tornado Watch 149...

Valid 200310Z - 200415Z

The severe weather threat for Tornado Watch 149 continues.

SUMMARY...The supercell tornado threat continues across southern
parts of Tornado Watch 149. A brief, short-term uptick in tornado
potential is possible with supercells merging with a baroclinic
boundary.

DISCUSSION...Three supercells are currently tracking northeastward
across portions of north TX, west of the DFW metroplex. The Parker
County supercell has a history of tornadoes, and tornado potential
will continue with both of these storms over the next few hours. In
the next 1-2 hours, these storms are poised to merge with a
baroclinic boundary, which has encouraged other storms to merge into
an MCS. With the boundary merger, a localized, brief uptick in
tornado potential may be realized, and a strong tornado may occur.
Thereafter, the storms will merge into the MCS and either become
embedded supercells, or LEWPs/bowing segments, with some tornado
threat persisting, though severe gusts will also be a concern.
