...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
NORTHWEST INTO NORTH CENTRAL TEXAS...

...SUMMARY...
Large hail and damaging winds remain possible this evening across
parts of northwest into north central Texas.

...01z Update...

Loosely organized cluster of thunderstorms is propagating southeast
across northwest TX. This activity will continue drifting southeast,
within modestly strong northwesterly flow that extends across the
southern Plains. Water-vapor imagery suggests a weak short-wave
trough may be associated with this convection, and this may
contribute to some longevity as updrafts are favorably sheared for
some organization. Latest radar data suggests large hail is noted
with many of these updrafts, and this appears to be the greatest
risk through the evening hours. Some increase in the LLJ is expected
across the TX South Plains later this evening, and this may aid
southward propagation.
